  1. Technology and Multimedia Communications Rachel Brown Julie Grimley Stephanie Kozikowski Peter North

  2. The integration of various forms of media Synthesis of: Text Graphics Animation Audio Still images Motion video What is Multimedia?

  3. Overview • History of Multimedia Technologies in Isolation • Beginning of Multimedia As We Know It • Modern-Day Multimedia Technologies

  4. History of MultimediaTechnologies in Isolation: Text, Image, and Audio

  5. Key Moments in Text • 1450: Invention of the Printing Press • 1702: First newspaper, The Daily Current • 1837: Invention of the telegraph • 1867: Invention of the manual typewriter • 1953: Electric Typewriter invented

  6. Key Moments in Still Image • 1837: Daguerreotype (photographic reproduction) invented • 1881: Halftone process enables mass reproduction of images • 1888: Kodak camera and roll film • 1947: First instant camera by Polaroid • 1996: Affordable digital cameras widely available

  7. Key Moments in Moving Image • 1888: Kinetograph (first motion picture camera) invented • 1895: First Motion Picture, La Sortie des Ouvriers de L’usine Lumiere a Lyon • 1906: First Animation Film, Humorous Phases of Funny Faces • 1980: First consumer camcorder

  9. Beginning of Multimedia As We Know It • Different media forms continued to develop in isolation, but they also began to converge…

  10. TEXT AND IMAGE 1839: Visual images in magazines (wood cuts and lithographs) IMAGE AND SOUND 1926: Demonstration of first television 1927: “The Jazz Singer” The Synthesis The First Talkie!!

  11. The Synthesis Continued INTERACTIVITY • 1972: First video game system • 1999: Birth of Napster • 2001: iTunes rocks the world

  12. The Synthesis Continued COMPUTER • 1958: First transistor computer • 1965: Word processor introduced • 1977: First PC with color graphics, Apple II • 1985: First true multimedia computer born, the Commodore Amiga

  13. The Synthesis Continued INTERNET • 1971: First email message • 1983: Birth of Internet • 1985: NSFNET connects supercomputers at 5 universities • 1987: Hypercard (helps construct interactive hypermedia documents) by Apple • 1991: World Wide Web introduced • 1992: Introduction of HTML

  14. Modern Examples of Evolved Hybrid Multimedia

  15. From Pens to Podcasts • Text synthesized with image, and then abandoned for sound and video. • One way communication limitation. • Ease of publication.

  16. MUDs and MMORPGs • Text evolved into image and sound.

  17. MUDs and MMORPGs • Added element of interactivity. • Two different sides of technological evolution.

  18. Evolution of Purpose I

  19. Evolution of Purpose II

  20. Modern-Day Multimedia Communications E-mail, Instant messaging, Blogs, and Wireless Communication

  21. The Internet • E-mail • Predates the internet, was crucial in developing the internet • Started in 1965 to aid communication between users of a time-sharing mainframe computer • Ray Tomlinson of ARPANET first to put “@” between name and machine in 1971 • Today, 91% of internet users between 18 and 64 use e-mail

  22. Instant Messaging Services • Began in 1970s using UNIX and other multi-user operating systems • Graphical User Interface (GUI) based messaging services (ICQ, AIM) developed in late 1990s • Originally a text-only form of communication like email, IM services now include • Video conferencing • Voice Over Internet Protocols • Web conferencing

  23. Blogs An abbreviation of “web log,” they are online diaries Began sometime in 1994; the actual word “blog” wasn’t coined until 1999 Predominantly text based, blogs today may also include photos, sketches, audio files/podcasts, videos, and hyperlinks Today, blogs have stretched beyond diary form, and they can be found discussing everything from politics to newspaper comics Blogs are being seen more and more as important sources of news not covered by mainstream media Hurricane Katrina CBS – “Rathergate”

  24. Wireless Communication • Developed as an offshoot of radio, wireless systems today use radio waves to transmit info • Two main forms of wireless communication today: Bluetooth and Wi-Fi

  25. Bluetooth Became popular by enabling communication between cell phones and hands-free headsets Low power consumption Range of 10~100 meters Can be used with a wide range of devices cell phones, laptops, printers, digital cameras, PCs, video game consoles

  26. Wi-Fi • greater power consumption than Bluetooth in exchange for a stronger connection • Need to be near a “hotspot,” or access point to use Wi-Fi enabled devices • Wi-Fi devices must be configured to transmit files and share resources and audio links • Faster connection than bluetooth, hotspots have better range, overall Wi-Fi is more secure • Wi-Fi allows users to connect to the internet and each other (through peer-to-peer mode)
