Frameworks (1):
  • Video for Windows: Microsoft platforms, proprietary standard, .AVI file format, codecs: Indeo, Cinepak, M-JPEG, MPEG
    • SW and HW decoders, DCI support, MCI application interface, disk oriented
    • Advantages: easy to integrate with applications; disadvantages: network support requires non-trivial custom programming
  • QuickTime: Apple (secondary: Windows XX, SGI), proprietary standard, general isochronous delivery framework, codecs: JPEG, Cinepak....
    • Modest video quality, no explicit network support (integration with OpenTransport pending), SW only
    • Popular Video CD/Games technology, spectacular QT-VR extension
    • Limited acceptance - rarely considered as professional network digital video platform
