    • Lecture 2
      • Multimedia Hardware and Software
    • MM hardware
      • We need to distinguish between hardware requirements for MM production , and hardware requirements for MM delivery
    • 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
    • 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
    • MM Delivery
      • Computer hardware to be used for running MM products requires particular specifications
    • Multimedia Hardware
      • Apple computers have had multimedia capabilities since 1984 (played sound)
        • Apple Macintosh series
      • Multimedia PCs available since late 1980s
        • 386 series
    • Apple Mac
      • Variety of Models since 1984
      • eg PowerPc, Quadra, Classic
      • Latest - iMac, G4 and G5, eMac
    • 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)
      • Full details can be found at:
      • www.apple.com/imac
    • 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 /
    • 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 /
    • PC
      • Multimedia PC (MPC) standard introduced to allow users to decide whether a particular PC was capable of running MM applications
      • 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.
      • MPC 2 1993
