1. Overview digital media...

2. Discussion -- revisit theory What does ‘the media’ refer to? Press, cinema, broadcasting, etc.) The ‘new media’ as a term? Less settled, known, identified Intensity of change Ideological connotations of new Non-technical inclusiveness (gui)

3. New Media… New textual experiences (hypertext, cgi) New ways of representing the world New relationships between subjects Shifts in the personal and social experience of time, space and place Unclear distinctions between human / artificial, nature / technology New patterns of organization and production

4. “Key terms in discourses about new media” Digitality – (vs. analogue) – assigning numerical values to phenomena Interactivity – an opportunity to manipulate and intervene in media Hypertextuality – when a work is made up of discrete units of material in which each one carries a number of pathways to other units Dispersal – distribution of information – for new media, through multiple input / output channels Virtuality – immersive experience, or identification of being in a space (MMORPGs, Second Life)

5. Key Terms... Postmodernism – a sense of blurring of boundaries between previously distinct or opposite phenomena: high culture / popular culture, local/ global, public/private Technoculture – Concept of a modern culture where technology has so deeply saturated into cultural practices that the two distinctively different spheres are seen to be inseparable CMC – Computer Mediated Communication Convergence – the coming together of previously discrete media forms and processes through digital technologies

6. But how did we get here?

7. Before personal computers... Mechanical computers Vacuum tubes Mainframe computers Transistor (Bell labs / Shockley, Bardeen, Brattain) Integrated circuit

9. Vannevar Bush (1890-1974) Many consider Bush to be the Godfather of our digital age, often making reference to his 1945 essay, "As We May Think." Bush described a theoretical machine he called a "memex," which was to enhance human memory by allowing the user to store and retrieve documents linked by associations. This associative linking was very similar to what is known today as hypertext.

10. Others… Gottfried Leibniz (math, logic, philosophy) Charles Babbage ( invented first mechanical computer) Alan Turing (father of computer science and artificial intelligence) Ted Nelson (‘discovered’ hypertext) Roland Barthes (structuralism, semiotics) Bill Gates?

13. Programs on the Internet… WWW -- Tim Berners-Lee devised HTML language which led to Mosaic A browser interprets the HTML What else has come along? XML--extensible markup language SOAP--simple objects access protocol (based on XML XHTML--another form of XML VRML

14. HTML extensions… Continued HTML development... HTML 5 CSS Cascading styles sheets -- a way to style HTML. Whereas the HTML is the content, the style sheet is the presentation of that document. PHP An HTML-embedded scripting language. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. The goal of the language is to allow web developers to write dynamically generated pages quickly."

23. Development of Technologies 3G cell phones -- packet and circuit switching EV-DO example 4G LTE -- ‘not true 4G’ Wi-Fi 802.11 and 802.11x refers to a family of specifications developed by the IEEE for wireless LAN technology. Institute of Electrical and Electronics Engineers, pronounced I- triple-E WiMax Also known as IEEE 802.16--intended for wireless "metropolitan area networks". Provides broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m).

24. Why 802? The 802 group is the section of the IEEE involved in network operations and technologies, including mid-sized networks and local networks. Group 15 deals specifically with wireless networking technologies, and includes the now ubiquitous 802.15.1 working group, which is also known as Bluetooth.

25. Other Wireless Technologies Bluetooth Name comes from Harald Bluetooth, king of Denmark in the late 900s There are lots of different ways that electronic devices can connect to one another--Component cables, Electrical wires, Ethernet cables, WiFi, Infrared signals… Bluetooth is essentially a networking standard that works at two levels: It provides agreement at the physical level -- Bluetooth is a radio- frequency standard; AND, it provides agreement at the protocol level, where products have to agree on when bits are sent, how many will be sent at a time, and how the parties in a conversation can be sure that the message received is the same as the message sent. (cell phone, GPS, PDA--Starfield example)

26. Other Wireless Technologies ZigBee The set of specs built around the IEEE 802.15.4 wireless protocol. Name "ZigBee" derived from the erratic zigging patterns many bees make between flowers when collecting pollen. The standard is regulated by a group known as the ZigBee Alliance, with over 150 members worldwide. Bluetooth focuses on connectivity between large packet user devices--laptops, phones, major peripherals…. ZigBee is designed to provide highly efficient connectivity between small packet devices -- thermostats, home appliances to the home network

30. Cell phone as a hybrid medium Delivery of video to cellular phones is becoming more widespread… voice / data … and Verizon’s V-Cast service; Sprint’s MobiTV service. Both use the cellular network to deliver the content. New service and technology, MediaFlo, developed by Qualcomm, uses part of the television broadcasting spectrum (channel 55) to send multi- media content to mobile phones. --see FloTV--see FloTV Allows wireless carriers to offer video content without taking up much needed bandwidth in their cellular network.

31. Broadband delivery -- wired DSL DSLAM / extenders (digital subscriber line access multiplexer) IPTV (AT&T: U-verse, Verizon: FiOS) Dedicated line (no slowdown) Cable modem (DOCSIS -- 1.0 / 2.0 / 3.0) Shared down trunk line (slowdown) Information service / no open access Fiber to the home/premises (FTTH/P) Or... FTTN -- fiber to the node (last mile is coaxial cable for cable & twisted-pair copper for DSL Broadband over power line (BPL) Interference State approval

32. Broadband delivery -- wireless Fixed wireless broadband (FWB) (from MMDS) 3G mobile wireless (4G / pre-4G / 4G LTE) Wi-Fi (IEEE 802.11) (‘WLAN’) Wi-Max (802.16) -- www.clear.com Satellite HughesNet & WildBlue Latency problem (VoIP, games) “a time delay between the moment something is initiated, and the moment one of its effects begins or becomes detectable” Some downlink only (dial-up modem uplink)

33. Broadband today (3) Sites like Metacafe.com, blip.tv, Veoh.com Hulu.com and others are driving a whole new category of video that could eventually be a more popular format than 30 or 60 minute programs.Metacafe.comblip.tvVeoh.com Hulu.com These days consumers themselves are driving this "broadband or TV" debate into irrelevance. They're busy accessing programming on demand - whether "broadband" or "TV" This is through a host of devices and services whose popularity is only going to skyrocket in the future. These include TiVo, Xbox, Netflix, Wii, etc.

34. Broadband Today (4) With the proliferation of available broadband video comes a massive user navigation challenge. Modern Feed launched (4/8/08) to address this. Now Clicker.Modern Feed Part search engine, part aggregator, with a specific focus on indexing professionally- produced programming, not user-generated video. It's also focused on actual programs, not promotional clips.

35. Broadband Today (5) J.D. Heilprin, Modern Feed's founder/CEO: But -- check it out and see if it has managed that the company is targeting mainstream users providing the easiest way to find available, high-quality video. It employs a team of "Feeders" charged with curating the best videos to include on the site. The result is approximately 550 "networks" and 25,000 pieces of content now indexed ”Networks" is a loose term ranging from traditional broadcasters to indies new entrants like Boston Symphony or Architectural Digest.
