Technological Hurdles
  • Video File Server Bandwidth
    • Needs real-time O/S support for I/O (network and disk)
    • Need better understanding of parallel I/O for multimedia
    • Need faster I/O hardware, especially tertiary storage:
    • high-end tape -- 1MBps
    • low-end tape -- 100 KBps
    • optical disk -- 0.5 MBps
    • (long to very long seek times)
