Digital Audio and Video II

Network bandwidth may be more important
- H263 needs 30-100 kilobits per second (POTS to ISDN) and is certainly suitable for video conferencing and educational material
- MPEG1 (1.5 megabits per second) or MPEG2 (many megabits per second) give entertainment quality but at significant network performance requirements
CD-ROMs will be able to have bandwidth and storage capability for many hours of MPEG1 quality video
Audio will run over POTS/ISDN and does not need ATM etc.
