What's the difference between SD, HD and Full HD? SD is the abbreviation for "Standard Definition", the standard image quality used in conventional analog broadcasting. HD or "High Definition" image quality appeared with the advent of digital broadcasting. While the number of horizontal scan lines on the TV screen used to be 480 for SD, HD has increased this number to 720 or 1080 lines, and the aspects ratio, which used to be 4:3 for SD was widened to 16:9 in HD, resulting in a wider screen format. The expression "Full HD" we hear a lot these days refers to a video component capable of accepting HD signals and able to display the full HD resolution of 1920x1080 (approx, 2.07 million pixels). And with the digitalization of TV and the marketing of network-ready components, techniques to compress video data became increasingly important. One of these is MPEG.IMPEG (Moving Picture Experts Group) was formed by the ISO (International Organization for Standardization) to set standards for audio and video compression and transmission. There are different standards for different media, as shown below. Main video standards 640×480 Resolution Analog broadcasting Remarks 1280×720 1920×1080 640×480 Digital broadcasting, PC, game machines Digital broadcasting PC HD SD 480p 720p 1080i 1080p 480i Standards Video compression standards Video CD Use Cell phones, etc., mobile communication Digital broadcasting, DVDMPEG-2 MPEG-4 MPEG-1 Standards Image quality Hi-vision only SD and HD refer to the image quality and resolution of TV broadcasts. 480 effective scan lines 1080 effective scan lines SDHD HD, with its greater number of scan lines, can deliver a more finely resolved picture. * See the image above.

The secret of producing the feeling of "being there" [H.264] What is H264? 「 H.264 」 is one of a family of standards recommended in by the ITU (International Telecommunication Union) in 2003 to standardize video coding techniques.It is used widely as standard format for moving pictures in a wide range of applications, including a terrestrial digital broadcasting service for cell phones called One Seg, Blu-ray Disc, portable video players, and game machines.Compared to conventional DVDs, MPEG-2 for digital broadcasting, and MPEG-4 for cell phones, H.264 is designed for a much wider variety of applications and offers 1.5 to 2 times the compression ratio.At the same video quality, it can reduce the data volume to nearly half. The H.264 technique is recommended by ISO (International Organization for Standardization), which cooperated with ITU in its development and formulation, to form a part of MPEG-4 (MPEG-4 Part 10 Advanced Video Coding).Therefore, both names are are normally used in the combined form "H.264/MPEG-4 AVC" or "H.264/AVC" when you read or hear about them.

The secret of producing the feeling of "being there" [AAC] What is AAC? As part of the MPEG audio compression specifications, the official name of AAC (Advanced Audio Coding) is MPEG-2 AAC. With 1.4 times the compression ratio of the previously used MP3 format, it is becoming the standard audio format in wireless communication, such as digital broadcasting and cell phones, as well as webasting. AAC is also used in MPEG-4, and an advanced form of AAC called HE (High Efficiency)-AAC has evolved through adoption of a technique for bandwidth extension.

The secret of producing the feeling of "being there" [SIP] What is SIP? A communications protocol is needed to control communication between PCs over a network.It follows certain rules and procedures to ensure that the system works properly.That is how the worldwide interchange of data over the Internet is made possible.SIP is an application layer-controlled protocol and falls into the 7th of the standardized layer model shown below.Other protocols are the standard Internet protocols IP in Layer 3 (Network), and TCP/UDP in Layer 4 (Transport), and the web and e-mail protocols HTTP and POP in Layer 5 (Session). The SIP (Session Initiation Protocol) is a VoIP (Voice Over IP) protocol widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP). SIP is a protocol for exchanging video and audio data between multiple parties and strongly favored in real time communication.

43 Q&A Appendix Automatic rate control: Adjusting the data volume transmitted to the level of network congestion Forward error correction: A system that adds redundancy to the transmitted data to allow the receiver to detect and correct errors without the need to ask the sender for additional data. (Error correction by time-consuming resending is not suitable for transmitting moving pictures, which requires real-time performance. ） Automatic repeat request: A system that notifies the sender when the network was unable to transmit data correctly and then retransmits only the unsent data. Because only the unsent data is retransmitted, the data volume transmitted via the network can be kept lower (However, the system is not suitable for applications with a large network delay, because requesting retransmission and retransmitting the unsent data requires time) Demarcation between forward error correction and automatic repeat request: FEC is used for networks with a large network delay, and automatic repeat request with its smaller volume of redundant data (required data other than video and audio) is used for networks with a small network delay. You don't have a choice between the two methods. Depending on the network delay, you use both by adjusting the balance adaptively to the optimum value.?? Decoder error hiding: Data packets where network transmission errors occurred, which cannot be corrected by FEC or repeat request, are subjectively and discreetly modified What is automatic rate control, forward error correction (FEC), automatic repeat request (ARQ), and decoder error hiding ? Please give a simple explanation. TRFC is short for TCP Friendly Rate Control. It refers to calculating the transmission rate based on the predictable TCP throughput on the same channel. What is rate control by estimation of the available bandwidth (TRFC)? QuestionsAnswers How much delay is there?One-way: less than 300msec 【 Breakdown 】 Main Unit delay (encoding/decoding): 200 to 220msec Camera/display delay ： approx. 60msec Transmission delay: depends on connection * Between Tokyo and Osaka over an optical fiber connection approx. 6msec When audio was still monaural, there was only one channel between speaker and microphone; in stereo, we have 2 speaker channels and 2 microphone channels, that is, 4 channels in all. In the past, it had been difficult to correct stereo echo because estimating the amount of echo is four times more complicated than for monaural. Panasonic applied independent component analysis to uniquely improve an algorithm for echo cancellation, and developed a stereo canceller that is capable of accurately estimating stereo echo. Full duplex audio: Audio amplified by the speaker is picked up by the microphone and returned. A system that turns off the microphone when the other party's audio is amplified by the speaker is called half duplex. On the other hand, a system where the other party's audio is continuously picked up by the microphone when amplified by the speaker, so that there are no gaps in the audio, is what is called full duplex. What is a stereo echo canceller? What is full duplex audio? What is unique about this technology? The analog signal output at the component terminal (YPbPr) can be videotaped. Can the customer record the visual and audio content of a meeting? It is capable of 360°stereo sound pick-up in all directions. When the video camera is located in the same direction as the speaker and the microphone faces the speaker, it will pick up the sound coming from the right for the left channel and the sound from the left for the right channel, so that the audio will be heard from the same direction as in the video. What are the special features of the Boundary Microphone? No problem. A VPN router is connected, and the Main Unit has a built-in AES encryption function. Are there any security problems when connecting to the Internet? QuestionsAnswers Is it correct to classify the system comprised of these products as a video conferencing system? It is a visual communication system that has changed the concept of the conventional TV conferencing system for being capable of showing even the texture of materials in full High Vision by simply connecting two ordinary digital video cameras. What novel features does it have? It features absolutely full duplex communication that allows parties to talk at the same time without experiencing clipped audio. Were there any obstacles to overcome in your development work? Yes, we had to solve the problem of providing high-definition visual communication given the low bandwidth of optical communication services, etc. available to the consumer. In what respect is your product superior to those of other manufacturers. ・ The HD quality and performance other companies offer at $30,000 is offered by us at $10,000. ・ You can talk at the same time without experiencing clipped audio (absolute full duplex audio) ・ You can use the system safely over an Internet connection. （ Rate control by estimation of the available bandwidth maintains communication quality and prevents packet loss. ） Can the customer connect a microphone other than the Boundary Microphone? Yes, it can be connected to the RCA terminal. In this case, however, some settings need to be changed at the receiving terminal because audio and video tend to get out of sync. Yes, you can connect a maximum of 4 Boundary Microphones in cascade connection. Can the customer install multiple Boundary Microphones?

44 The video camera can be controlled with the remote control that came with the camera. （ Digital Video Camera HDC-TM700: Zoom, System Camera AW-HE50: Pan, tilt, zoom) How do you operate the camera's zoom and pan functions? No, it does not.Does the interrupt function of a remote conference point work during a communication? No record remains in incoming call log for the following cases. 1, Receiving incoming call while system is activating 2, Forced disconnection of incoming call due to malfunction 3, Mismatch of encryption setting of incoming call 4, Mismatch of system version of incoming call 5, Incoming call while calling 6, Receiving incoming call at the same timing as outgoing call then return to standby screen after "collision of outbound and inbound call" is displayed 7, Incoming call while system error 8, Incoming call while maintenance (service stop) Occasionally, incoming call log record does not remain. No record remains in outgoing call log for the following cases. 1, When calling the wrong IP address 2, When receiving incoming call at the same timing as outgoing call, call operation is invalid and incoming operation is conducted. Occasionally, outgoing call log record does not remain. At this point, it is unable to determine whether it is 2 point call or 3 point call. Unable to determine whether inbound and outbound call log is 2 point call or 3 point call. Please check the energy saving setting (no signal automatic OFF function) of TV. When no signal automatic OFF function (function that turn power OFF automatically after a certain time when visual input becomes no signal) of TV is valid, image will not show even if turning screen standby OFF. Either void no signal automatic OFF function or power cycle of TV. Image is un-shown even if turning screen standby OFF. You can connect any display or camera having an HDMI interface. In this case, however, we cannot guarantee performance. Input resolution for the camera should be 1080i. Can I connect a display or camera by a different manufacturer? Please set TV screen display mode to full screen display. Please refer to TV instructions before use. For Panasonic brand TV: Set up to “full size ” for “HD display domain” of “screen setting” of “set up”. Top/bottom or left/right of screen may seem chipped. QuestionsAnswers It could affect the company's network bandwidth. And this could in turn seriously affect the customer's current operations. Please suggest applying for a separate line. Can you run the system over a company line? An HD-ready or Full HD-ready projector can be connected to an HDMI or analog component signal. Can the customer connect a projector? You can connect the HDMI terminal and the component terminal to different display devices and display the same picture. Displaying the camera image and the image on the PC screen on different display devices is not possible. Can the system handle video output from multiple display devices? Can it output the camera image and the image on the PC screen to different display devices? When setting as automatic incoming call, unintended call may automatically be received with a threat of peeping. Provide a thorough explanation to customers and upon recognition of the threat, turn power OFF when it is not in use. For automatic incoming call, what are necessary items to pay attention to? It is not compatible with the HDMI signal of components with HDCP functional protection. * For example, it cannot transmit the HDMI output of DIGA recorders. Is it HDCP compliant?

45 Terms you would want to know: Audio Visual 4K2K Image display technology with a high resolution of around 4,000 (H)×2,000 (V) pixels. "K" stands for "Kilo". It has roughly 4 times the number of picture elements of Full HD (1,920×1,080). Occasionally it also refers to a specific resolution, such as 3,840×2,160 or 4,096×2,160. DVI (Digital Visual Interface) A video interface standard developed for connecting a computer display device to a computer. It is designed to allow direct transmission of digital signals from a computer to a digital display device such as an LCD. It uses TMDS (Transition Minimized Differential Signaling), a serial transmission format developed by Silicon Image, Inc. Previously, image data stored in digital format on the computer was first converted to analog signals and then output to the display. DVI eliminates signal degradation due to conversion, resulting in a higher image quality. EL (Electroluminescence) Display A display that makes use of an optical and electrical phenomenon where a material emits light in response to an electric current passed through it. This is made use of by depositing electroluminescent material on a glass substrate and controlling an electric voltage applied to the substrate to achieve a display effect. EL uses a low electric current to produce high levels of luminance, visibility and response speed, and offers a long lifespan and low power consumption. Electroluminescent display devices can be designed as flat panels like LCDs. Depending on whether the deposited material is inorganic, such as zinc sulfide, or organic such as a diamine, they are referred to as inorganic or organic electroluminescent displays. The inorganic EL display of the past had problems, including difficulties with color display, which limited its applications. Practical uses include displays for medical equipment, cash registers in 24- hour convenience stores, and computer displays aboard the space shuttle. In recent years, research is proceeding with organic EL displays which do not have the shortcomings of inorganic EL displays, and they have found applications in areas such as displays for handheld devices. The EL principle is also used to produce backlights for LCDs. FSTN (Film Super Twisted Nematic) LCD Uses a single film compensating layer (film) between the LCD panel and rear polarizer for added sharpness and contrast. Types using 2 compensating films are called TSTN (Triple Super Twisted Nematic) LCDs. With many of the STN and DSTN LCDs of the past, light was polarized elliptically because of the wavelength used elliptically polarized, and there were problems not only with color display but with black-and-white display, as well. To compensate for these shortcomings, FSTN has a phase- compensating, birefringent polymer film applied to the surface of the LCD operating cell to improve the liquid display performance. This results in a reduction in size and weight, lower power consumption and lower cost as compared with conventional displays. FSTN LCDs are, therefore, often used in cell phones and PDAs (Personal Digital Assistants), but because the shortcomings of the STN type have not been overcome completely, the TFT type is the mainstream for use in notebooks and LCDs. TFT (Thin Film Transistor) LCD A type of LCD display that uses thin-film transistor technology. The transistor is formed by applying amorphous silicon, etc. on a glass substrate. It is used for LCD panels. PDP (Plasma Display Panel) A type of flat panel display (FPD), where a rare gas is enclosed between two panels of glass and made to emit light by application of a high voltage. The principle was discovered in 1966 at the University of Illinois in the USA, in the 1980s plasma display panels came into use as computer displays, and in 1997 they became generally popular with the release of plasma television sets by Pioneer. The principle is the same as that of a fluorescent lamp. A rare gas, such as helium or neon, at high pressure is enclosed between 2 glass plates to form electrodes. Applying an electric voltage causes the gas to ionize and form a plasma. Compared with other display technologies such as the LCD, the PDP features a higher response speed, a higher contrast ratio, a wider viewing angle, and it can be produced in larger sizes, all characteristics that have contributed to making it the most popular large size flat panel television (plasma television). Aspect ratio The aspect ratio of a screen or an image is the ratio of its height to its width (number of pixels). Whereas ordinary computer displays, terrestrial TV broadcasts and BS broadcasts except for Hi-Vision, have an aspect ratio of 4:3, Hi-Vision broadcasts including BS digital broadcasts use the 16:9 aspect ratio, resulting in a screen that is greater in width than in height. Computer monitors such as SVGA, XGA, UXGA, and SXGA+ have an aspect ratio of 4:3, only that of the SXGA monitor is 5:4. Some notebooks and PDAs will have other aspect ratios like 2:3, which means they are higher rather than wide. Liquid Crystal Display (LCD) Refers to a display device that uses liquid crystals. A structure to electronically display an image is obtained by supplying an electric charge to a liquid crystal material enclosed between two glass substrates to change the direction of the liquid crystal alignment, and increasing and decreasing light transmittance. While the crystal material itself does not emit light, a display is produced by using reflected light to reproduce bright areas and fluorescent light projected ?? from the rear (backlight) to reproduce dark areas. LCDs are roughly divided into passive matrix types such as STN and DSTN, and active matrix types like TFT, the former being cheaper to produce but inferior to the latter in terms of performance. Compared with other display devices such as CRT displays and PDPs, LCDs are thinner and lighter in weight, and are therefore the preferred choice for portable computers and small- footprint desktop PCs.

46 Terms you would want to know: Audio Visual Film valid pixels The pixels of an image which a digital camera or similar device records on a digital media such as a memory card. A digital camera converts from several hundred thousand to several million light- receiving elements to electric signals to record an image, but because the elements in the surrounding area often contain noise, not all elements are converted. For this reason, the number of light-receiving elements contained in an image differs from the number of pixels output to record the image. Since products have come out recently which are designed not to output one pixel for each picture element (for example, the Super CCD Honeycomb SR by FujiFilm), it is not always the case that each effective pixel becomes a film valid pixel. In other words, it is common for a digital camera delivering 1.3 million total pixels to output only 1280×960 pixels corresponding to a 1,228,800 pixel image. The total number of light-receiving elements equipped is referred to as total pixels and the number of elements that actually function and are recorded is called effective pixels. Transmissive liquid crystal A liquid crystal type that displays using the backlight behind the screen as light source. Compared with the reflective liquid crystal which displays by reflecting external light, the transmissive liquid crystal offers high saturation, giving it good visibility in darker indoor locations. Its disadvantages are that its power consumption is high and that it appears dark in bright outdoor locations. Recently a semi- transmissive type of liquid crystal, representing a combination of the reflective and the transmissive type, has come out, which uses backlight in the dark and external light in bright locations. Pixel A digital image consists of colored points. A digital image is formed by arranging these pixels orderly lengthwise and breadthwise in a square (rarely rectangular) grid. Multiscan display A display that supports multiple scanning frequencies. Depending on the type/performance of the PC and as needed, it can select several different display resolutions. In the past, displays that can use only a certain resolution for a certain type of device used to be common, but nowadays the majority of displays support multiscan. The performance index, a combination of display area and dot pitch, expresses the maximum resolution a display is able to handle. Mega-pixel A unit to measure the performance of digital cameras having a resolution of 1 million pixels and more. This class of digital camera is called a "mega-pixels camera" or "mega-pixel device". When digital cameras equipped with a 1-million-pixel or more CCD first appeared, "mega-pixel picture quality" and the like became widely used buzzwords. Terms like "1.92 mega-pixel" (= 1.92 million pixel) continue to be used to express the resolution of a digital camera. In fact, most of the digital cameras sold these days are mega-pixel cameras. Screen resolution Refers to the resolution of display devices such as computer monitors. In Japan and in the US, the total number of pixels used to describe a 1024×768 display is often referred to as resolution (screen resolution, browser resolution) in the computer field. This, however, is not the original meaning of the term.

47 Terms you would want to know: Storage AVCHD A format for home-use digital cameras used for shooting and recording of high-definition video. It was jointly developed by Sony Corporation and Panasonic (formerly Matsushita Electric Industrial Co., Ltd.) and announced in May 2006.The AVCHD format allows video signals to be compressed in the MPEG- 4 AVC/H.264 format and recorded on 8cm small DVD disks. It is planned to expand this in the future to recording on hard disk drives, memory cards, etc. The main aim of AVCHD is to allow the recording of HD TV quality video even with lower volume and lower speed media by using the H.264 format with its high compression ratio. People say said that with a double-speed 8cm DVD, you can achieve almost the same image quality as with an HDV standard tape cassette. On a single-sided disk, you can record roughly 20 minutes, and on a double- sides disk 40 minutes. The audio recording format used is Dolby Digital, allowing recording of highly realistic audio in 5.1-channel surround. The video recorded on disk can be played back on an AVCHD- compatible Blu-ray Disc player, Sony's Playstation 3, etc. Blu-ray Disc A rewritable phase change optical disk for large storage volumes developed jointly by nine companies, including Sony Corporation and Panasonic (formerly Matsushita Electric Industrial Co., Ltd.).It is a standard for the so-called "next generation DVD" with a larger storage capacity than the current DVDs. An optical disk with the same diameter as a CD or DVD, it is enclosed in a cartridge and has a maximum recording capacity of 27 GB and a data rate 36Mbps. Using the shorter wavelength blue- violet laser, it achieves a track pitch of 0.32μm, which is roughly half that of the DVD, and reduces the minimum pit length of each layer to around 0.14μm, resulting in a higher recording density. As the format is mainly intended for consumer-oriented video recording applications, each disk has a serial number recorded on it with copyright protection in mind. RAID A technology where two or more physical hard disks are combined into a single logical unit. RAID is an acronym first defined by David A. Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987 to describe a redundant array of inexpensive disks. By distributing data over multiple disks for recording, RAID increases input/output speed and data reliability. It does so by using special hardware or software. We differentiate by speed and data reliability between different RAID levels numbered from RAID-0 to RAID-5. Volume In the present context, volume refers to OS formatted continuous storage areas, mainly a management unit for an external recording device.???? When referring to a hard disk, the disk is either taken to be one volume or is divided into partitions and each partition is called a volume.??? When composing a RAID disk array, a combination of multiple disks can sometimes be taken to be a volume. In case of removal disks, one medium corresponds to one volume. The name assigned to identify volumes is also referred to as volume (or volume label). memo Appendix

It performs signal conversion and error control. It is usually built into the computer. Cisco Systems A US manufacturer of communications equipment founded in 1984. The company is engaged mainly in manufacturing and sales of equipment for telecommunications carriers. It is one of the world's largest makers of communication devices such as routers and switches used in Internet and corporate communication networks. It also conducts qualifying exams to certify the knowledge and skills of engineers handling the company's products and is widely known among communication experts. It was incorporated in Japan in 1992 under the then name of Cisco Systems Japan, Inc. (currently Cisco Systems G.K.), where it engages in sales of Internet communication equipment, etc. PBX (Private Branch eXchange) Refers to a telephone exchange that connects the internal telephone lines of a business or provides connection to public networks such as the public switched telephone network (PSTN) and the Integrated Services Digital Network (ISDN).You can build up a wide-area telephone network by interconnecting PBXs over dedicated lines. PPP (Point-to-Point Protocol) A protocol that is widely used to set up a dial-up connection between a computer and a network. It corresponds to the data link layer of the OSI reference model and is designed to work with numerous network layer protocols. It can provide authentication and compression functions and will see extended use in the future as new protocols are adopted., PPPoE (Point-to-point protocol over Ethernet) A network protocol that enables the use of PPP over Ethernet. It was standardized as RFC 2516 by the IETF (Internet Engineering Task Force), an organization that develops and promotes Internet standards, While PPP was originally developed to connect to a network over communication lines requiring call requests [??] such as telephone lines and ISDN lines, PPPoE is a version of PPP adapted to allow "always on" connections via a LAN, etc. Different from ordinary PPP, PPPoE identifies both computers by a unique MAC address and sets up a virtual channel between them. With PPPoE, user authentication, IP address and so on can also be assigned over a LAN. It also lets you switch easily between providers of always-on connection services such as ADSL, CATV and optical fiber networks. Many ADSL providers in Japan, as well, use PPPoE. Echo canceller Device or technology designed to prevent the input device from picking up electric signals or audio output, resulting in the generation of echo and howling. With a phone, for example, you could experience echo and howling when the phone's microphone picks up output from the speaker. To prevent this, the handset has an echo canceller built in. There are also external devices designed to suppress echo and howling among microphones, speakers and audio equipment. Last one mile The "last one mile" or "last one kilometer" is the final leg of delivering connectivity from a communications provider to a customer. Because the last mile of a network to the user is also the first mile from the user to the world, "first one mile" is sometimes used, but terms change as an increasing number of companies rethink their user focus. In Japan, the last one mile consists mostly of phone lines, on which NTT WEST and NTT EAST have a near monopoly. Making improvements to the communications environment is difficult, and while there is a growing demand for high-speed connections, low line speeds and high communication charges are the bottleneck. To improve this situation, some carriers have started to lay independent optical fiber into subscribers' homes by using wireless LAN and FWA (Fixed Wireless Access) technology to avoid the use of NTT's metal lines, while cable network television stations tend to use CATV coaxial cables for connection to the Internet or phone services. At the same time, with lifting on the ban on connection to Main Distributing Frames (MDF), ADSL which realizes high-speed always-on connection of high-frequency digital signals came into practical use even among carriers using NTT's metal lines, and many start-ups became subscribers.

49 Terms you would want to know: Network 100BASE-T A cable standard developed by the IEEE802.3 Committee for Ethernet networks running at 100Mbps. The standard covers twisted pair cables for a transmission distance of 100m in star connection. The categories concerned are UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair) category 5 cables or higher. DHCP (Dynamic Host Configuration Protocol) A protocol that automatically assigns the necessary configuration information such as an IP address to computers that are temporarily connected to a network like the Internet. It allows users to connect with the appropriate settings without having to configure the network connection manually, so that even inexperienced users can easily establish a connection. It also facilitates uniform management of a large number of clients by a network administrator. DNS （ Domain Name System ） This system matches host names to IP addresses on the Internet. It serves as a distributed database to which DNS servers worldwide contribute.It can resolve IP addresses based on host names and vice versa. Each DNS server possesses information on the domain it administers and stores its domain name and address in the 10 root servers in operation worldwide. H.323 A protocol used in the implementation of videophone systems, etc. that defines the audio, video, and compression/decompression system for sending and receiving one-to-one audio and video over a network. Designed for handling everything from VoIP to video conferencing, H.323 has found many applications. As network speeds keep increasing and computers become ever more powerful, it has come to be recognized as a useful protocol. A typical example of an H.323 application is Microsoft NetMeeting included with Microsoft's browser. HTTP A protocol used by web servers and clients (web browser, etc._) to send and receive data. It can be used to transfer files containing HTML text, images, and audio/video associated with text, together with information such as semantic representations. IEEE 802.1x A standard that provides an authentication mechanism for LAN users. IEEE 802.11b, in particular, is widely recognized as a user authentication specification for wireless LAN users and also supports wired LAN. It prevents all communication from clients whose authentification fails (except authentication request) and allows establishment of a connection only for authenticated clients. It also allows for regular re-authentication to prevent port scanning by other users. IP （ Internet Protocol ） A protocol developed by the Network Project of the U.S. Department of Defense. It corresponds to the third layer (network layer) of the OSI reference model and defines methods for assigning addresses (addressing) to devices using the network and selecting the communication path (routing) inside multiple interconnected networks. Because it is a connectionless protocol, it needs to be used concurrently with TCP in the next higher layer to ensure that data reaches its destination without fail. IPv6 （ Internet Protocol Version 6 ） A next generation Internet protocol (IP) designed to succeed IPv4, which is threatened with address exhaustion in the foreseeable future, to implement improvements such as a vastly larger address space, additional security features, and hierarchical route aggregation. MCU (Multipoint Control Unit) The Multipoint Control Unit (MCU) is an endpoint on the LAN that provides TV conference systems with the capability for 3 or more terminals to participate in a multipoint conference. Some MCUs are integrated with the TV conference terminal. MTU （ Maximum Transmission Unit ） MTU is the size (in bytes) of the largest protocol data unit that the layer can pass onwards. The value of the MTU can be fixed at the sending terminal. If the MTU of the sending host is greater than that of the receiving host, the sending terminal will repartition the data according to the MTU on the receiving side before sending it. Given that error data is retransmitted in units designated by the MTU, choosing a smaller MTU under bad communication conditions can result in a higher transfer rate. The MTU is expressed in bytes; the appropriate value for Ethernet is about 1500 bytes, that for a dial-up connection is around 576 bytes. ONU (Optical Network Unit) The ONU is a device for connecting a terminal such as a computer to an optical fiber subscriber network. It is installed in the subscriber's home. SMTP (Simple Mail Transfer Protocol ） A protocol for sending electronic mail (e-mail) across the Internet or an intranet. It is used for transferring e-mail between servers and for sending e-mail from the client to the server. T1 A standard for Digital Private Lines (DPL) established by ANSI (American National Standard Institute) and used in Japan and North America. It applies to the 1.5Mbps (=24 x 64kbps) bandwidth. In Japan it is implemented by optical fiber. As video conferencing usually takes place over ISDN-PRI lines, it is used with 23 B channels + 1 D channel or 24 B channels. In video conferencing, it is applied mainly to the MCU or GW. The corresponding standard in regions other than Japan and North America is E1 。 T.120 An international standard for multimedia conferencing recommended by the. It deals mainly with subjects such as whiteboards, application sharing, and file transfer. An example of T.120 compliant software is Microsoft's NetMeeting. TCP/IP (Transmission Control Protocol/Internet Protocol) A set of communications protocols used for the Internet, intranets and other similar networks. It is the result of a process to develop a computer network that would not fail in its entirety even if the U.S. Department of Defense was partially destroyed by a nuclear attack. Appendix

50 Terms you would want to know: Network VPN (Virtual Private Network) A service that provides a secure extension of a private network into an insecure network such as the Internet. VPNs are often installed by organizations to provide remote access to a secure organizational network, because this is cheaper than installing a private line. Global address The IP address uniquely assigned to all devices connected to the Internet. It corresponds to the address of a device on the Internet and is required for communicating over the Internet. Ethernet The most widely used LAN standard designed by Xerox and DEC and standardized by the IEEE 802.3. Committee. Ethernet is divided into varieties based on quality. Subnet A subnet is the product of breaking up a large computer network into several smaller networks and is used as a management unit for managing a network. A huge network like the Internet consists of a large number of interconnected smaller networks. Large companies and organizations may break up their network into several smaller units for better network management and more efficient allocation of line resources. These smaller networks used as management units are called subnets. The IP address that identifies the computer's address as per TCP/IP consists of the address of the subnet in which the computer is located (subnet address) and the address of the computer in the subnet (host address), while the higher-order bits are called the "subnet mask" and indicate the network address. Redundant Packet Refers to the sender sending extra data packets rather than just the minimum required data volume, to ensure that even if some packets are damaged, video and audio data can be made available continuously. Hub A device used as a branching or routing point for network cables forming a LAN or other network. With a single hub you can build up a small and simple LAN. hub. It has several RJ-45 ports and is used with 10BASE-T Ethernet cables (Ethernet over twisted pair). There are many other types of hubs for different uses, such as hubs that control the network speed (10BASE-T, 100BASE-T, switching hub) and so-called intelligent hubs equipped with management functions. Port Communication over a TCP/IP network uses a port number from 0 to 65535 as auxiliary address assigned under the IP address of communication devices and individual computers. This makes it possible to provide multiple services with one computer and to communicate simultaneously with multiple computers. Router An electronic device used to forward data between computer networks. In terms of the OSI reference model, it forwards using the network layer (layer 3) protocols and some transport layer (layer 4) protocols. Using its path select function, it checks the network layer address and decides the forwarding route. Any data that does not correspond to its own protocol is discarded. memo Appendix

51 Terms you would want to know: Multi Media DLNA (Digital Living Network Alliance) A standard used by manufacturers of consumer electronics to allow entertainment devices within the home to share their content with each other across a home area network (HAN). The term is also used to refer to devices that have it built in. fps A term to express the smoothness of video images. fps refers to the number of frames displayed per second. HDMI (High-Definition Multimedia Interface) A standard for a digital audio/video input/output interface, applicable mainly to electronic household appliances and audio/video equipment, that was formulated in December 2002. HDV (High-Definition Video) A recording method for digital video, that records video in HDTV equivalent quality on DV cassettes. NTSC (National Television System Committee) Name of the U.S. standardization body that developed the standard for the ground-wave analog color television broadcasting system. The standard adopted 525 horizontal scan lines and 30 interlaced frames per second (image is refreshed 30 times per second), a horizontal scan frequency of 15.75kHz and a vertical scan frequency 60Hz. PAL (Phase Alternating Line) A method for ground-wave analog television broadcasting. A broadcast television system developed in Germany in 1967 that was adopted in large parts of the world, including Western Europe except France, China and other countries in Asia, and Africa. The standard adopted 625 horizontal san lines (525 in Brazil) and 25 interlaced frames per second (image is refreshed 25 times per second). VOD (Video On Demand) A service which allows users to select and watch video content on demand. Drop frame Drop frames are frames which for some reason are dropped from a video (not played back). Composite video A system for transmitting video signals by combining the luminance signal and the color signal into one signal. Component Video A system for transmitting video signals where the color components are separated from the video signal and processed independently. For connection between equipment, there are three terminals to which the component cable, composed of three bundled cables compatible with each of the terminals, is connected.??? Howling (Audio feedback) This refers to a phenomenon where the sound output by a speaker is picked up by a microphone and fed back to the speaker, resulting in a continuous sound loop accompanied by a high-pitched squealing noise. Pan/Tilt Panning of the camera refers to its rotation in a horizontal plane, tilting refers to its rotation in a vertical plane. Frame rate Describes the frequency (rate) at which an imaging device produces unique consecutive images per second when playing back video. White balance In the context of cameras, this refers to a function that corrects neutral colors such as white, to ensure that they are reproduced correctly under light sources of varying color temperatures. Without applying white balance, a color that appears natural to the naked eye, will look unnatural when photographed with a camera. For example, when shooting with daylight film or using daylight white balance under fluorescent light, the image will appear unnaturally greenish. On the other hand, when shooting an object lit by incandescent light using daylight film, the image appears slightly orange colored. This is compensated by white balance. 720p A video standard for an HDTV video mode with an aspect ratio of 16:9, 1280 (H) x 720 (V) pixels, and progressive scan. 1080i A video standard for an HDTV video mode with an aspect ratio of 16:9, 1920 (H) x 1080 (V) pixels, and interlaced scan. 1080p A video standard for an HDTV video mode with an aspect ratio of 16:9, 1920 (H) x 1080 (V) pixels, and progressive scan. Interlaced scan A monitor display format also called interlaced scan. A small "i" is often attached to the name of video standards such as 1080i to make the distinction between interlaced and progressive scan. It alternately scans or displays the odd lines and the even lines of an image. It uses half the bandwidth that would be required for a full progressive scan while maintaining the necessary refresh rate to prevent flicker. Progressive scan A monitor display format also called non-interlaced scan. A small "p" is often attached to the name of video standards such as 1080i to make the distinction between progressive and interlaced scan. It scans or displays the lines of each frame in numerical sequence. Progressive scan requires higher bandwidth than interlaced video, but suppresses screen flicker. Appendix
