  1. Lecture 2 Multimedia Hardware and Software

  2. MM hardware We need to distinguish between hardware requirements for MM production, and hardware requirements for MM delivery

  3. Producing MM • MM production requires high quality, high speed equipment with massive storage • Need to store, and process, vast amounts of MM data such as images, sounds, and video

  4. Producing MM • Need to be able to capture video from camera to disc, at a constant rate • Need to be able to record sounds using high quality microphones in a sound studio

  5. MM Delivery • Computer hardware to be used for running MM products requires particular specifications

  6. Multimedia Hardware Apple computers have had multimedia capabilities since 1984 (played sound) • Apple Macintosh series • Multimedia PCs available since late 1980s • 386 series

  7. Apple Mac • Variety of Models since 1984 eg PowerPc, Quadra, Classic • Latest - iMac, G4 and G5, eMac

  8. Apple iMac • iMac is entirely suited for MM use • Has high-level spec for: • Processor and memory • Storage • Graphics • Communications • Audio • Optical storage (cd/dvd / rewrite options)

  9. Full details can be found at: www.apple.com/imac

  10. G5 Spec • More advanced than iMac • better processor 1.8-2.5 GHz single/dual • more memory 256Mb - 8Gb • more hard disk space 80-500 Gb • see notes pages: www.apple.com/powermac/

  11. eMac eMac now also available 128-256MB SDRAM - 1 DIMM Keyboard/Mac OS X - U.S. English 1.25GHz PowerPC G4 40-80GB Ultra ATA drive DVD-ROM/CD-RW Combo drive Mac OS X and Mac OS 9 included www.apple.com/emac/

  12. PC Multimedia PC (MPC) standard introduced to allow users to decide whether a particular PC was capable of running MM applications

  13. MPC 1 1989 • 386sx, 2mb ram, • 30 mb hard disk, • CD ROM Drive, • VGA video (16 colours), • an 8 bit audio board, speakers and/or headphones • Microsoft Windows software with Multimedia Extensions package - not powerful.

  14. MPC 2 1993 • 486sx 25 mhz, 4mb ram (minimum), • 160 mb hard disk, • CD ROM (double speed), • VGA video (64k colours) display resolution (640x480), • a 16 bit audio audio board (digital sound, midi playback), • 101 keyboard and mouse, midi, joystick, serial, parallel, • Windows 3.0, plus multi media extensions

  15. MPC 3 1995 • Pentium 75 mhz, 8mb ram (minimum), • 540 mb, CD ROM (quadra speed), • VGA video (64k colours) ( video enable graphics), • 16 bit audio board (digital sound, wavetable, midi playback), speakers must be measured at 3 watts per channel, • video playback, • 101 keyboard and mouse, joystick, serial, parallel, • windows 3.11 and DOS 6.0

  16. PC Today • Provides high-spec hardware and software capable of supporting MM applications • Vastly exceeds MPC 3 requirements • Distinction of ‘Multimedia PC’ no longer needed

  17. Example specification • 3.6 GHz pentium 4 processor • 512 – 4Gb memory • 160 Gb hard drive • cd/dvd rewrite • Windows XP • ~£1000

  18. Peripherals for multimedia • Extra Storage • external • hard discs • cd readers/writers • zip drives • dvd players/writers

  19. Input Devices • Trackballs • Touchscreens • Graphics Tablets • Scanners • OCRD • Infrared Remotes • Voice Recognition Systems • Digital Cameras (still and video)

  20. Output • projectors • video

  21. Software for multimedia • Multimedia application development software • eg Macromedia Authorware, Macromedia Director, Assymetrix Toolbook, Flash • Graphics Creation and editing software • eg Adobe Photoshop, Paintshop Pro, Adobe Illustrator • Text • Abobe Pagemaker, Adobe Framemaker, MS Word

  22. Software • Video • Adobe Premiere, Final Cut, iMovie, Cinema 3D • Sound • provided with sound card, eg Soundblaster for PC and Macintosh sound software • Web • Macromedia Dreamweaver, Adobe Go Live, Macromedia Flash and Macromedia Fireworks, shockwave www.shockwave.com
