1 Multimedia Components (Develop & Delivery System)  Introduction  Multimedia Computer develop system  Multimedia Application Develop  Multimedia Personal Computer  System requirement for MM Develop  Multimedia Delivery system

2 Introduction l Hardware environment for developing multimedia lMultimedia programs with digital sound, stills, animation, and motion video increase the required performance needs of a personal computer to a completely new level lTechnology has moved forward with faster, more efficient microprocessors such as the Power Mac and Pentium

3 MM Computer Development system Typical Hardware Components of MPC

4 Features of MM Computer Development system ¥ Windows-based and Macintosh computers are used to create multimedia titles. Because the Macintosh was the first popular personal computer to provide a graphical interface - has superior handling of graphics and cross-platform capabilities, it has been used extensively in multimedia development. ¥ Today, a Pentium III 500 processor is considered the minimum needed for development work. A Pentium tit 750 or better is desirable ¥Multimedia titles are extremely memory-intensive. 128 MB of RAM min Req., with 256 MB being more desirable. ¥For video -digitized using a video capture card. The card fits internally within the computer, and a video source (camera, VCR, TV) is then plugged into the card.

7 hardware components of the basic computer model communicate with microprocessor software components of the compter communicate with the operating system

8 Multimedia applications offer significant challenges to computer architecture in terms of its ability to:  Input various data formats  Store and retrieve digital multimedia data  Manipulate and edit multimedia data; for example, editing graphics, audio, and digital video files  Output multimedia data including converting digital version into an analog format suitable for the end user

9 Hardware Elements in MM Computer

10 Hardware Comp of Multimedia Computer System

11 Inputs: Keyboards- also special layouts for limiting and controlling user input Mouse-also track balls, joysticks, and similar devices Graphic tablets-used in drawing and painting applications Scanner-capable of capturing images ranging from black and white to millions of colors Digital camera-capable of capturing and converting images and video directly into a computer-digital format Analog audio input from microphones and audio player sources Analog video input- raw and processed video input. Some hardware systems even decode television signals for display. Network support for distribution of multimedia files Modem

12  Outputs  High resolution monitors capable of displaying black and white to millions of colors. A 256-color display is considered the minimum requirement for multimedia display.  Specialized projection devices to replace or augment single user monitor/displays for larger audiences. These devices usually function in lieu of or simultaneously with a computer monitor.  Audio output to speakers or to other audio devices such as amplifiers or tape devices. Raw video output for television monitor display-the computer typically creates a television video compatible signal

13 Specialized Multimedia Hardware Multimedia hardware focuses on the ability to capture, store, and present text, pictures, audio, and video. Each type of data, the computer must be able to convert it into digital format and store that data in a file. This file can then be edited and/or applied into a multimedia presentation product. The presentation software, in conjunction with the operating system, then converts the data back into an analog format that can be viewed, heard, or experienced by an end user

14 Fig 3.8 Cost Comparison of various forms of Storage

15 Types of Storage devices

16 Access methods n Sequential access: records must be retrieved in order n Direct access: records can be retrieved in any order –Direct access storage devices (DASDs)

17 Devices and Media: Magnetic Media n Magnetic tapes n Magnetic disks n RAID n Storage Area networks (SAN)

18 Devices and Media: Optical Media n Optical disks –CD-ROM –CD-W (aka WORM) –CD-RW n Magneto-optical (MO) disks n Digital video disks (DVDs)

19 Three Stages of Audio and video Capture, storage and Playback

20 Video hardware consists of devices to display and capture video. Video display devices, often called graphics adapters, enable the computer to present information on monitors capable of displaying up to 16 million colors
