BASIC REQUIREMENTS AND LIMITATIONS

• Speed of access ????????????????????
• Interactive or one-way
• Quality of the signal
• Richness of signal
• Security
• Mobility
• How much does it cost?

34
BIT-RATEANDLATENCY

• ?????????? delay ????????????????????
  ??????????????? ?????????????????????
  ????????????????????????????????-?????????

36

• In general, the strictest requirement for
  entertainment multimedia is in the need for a
  sufficient bit-rate to cope with high quality
  video and sound. Delay is not an issue because
  there is no need to get the content exactly when
  it happens. In interactive conferencing, the
  requirement is exactly the opposite limited
  bandwidth is acceptable, but long delay is not.
