Futures:
-
MPEG-4:
-
currently in application identification phase. Standard expected end of 1998. Intended for very narrow bandwidth.
-
Compression class A (10 kbps), class B (48 kbps), class C (320 kbps)
-
Probably will include speech and video synthesis (compare to MIDI) and artificial intelligence technologies to build high fidelity pictures from minimal data.
-
Compression class E (synthetic images)
-
Certain probability that the H.263 standard will become heart of MPEG-4
-
Wavelets:
-
Most recent data compression technology discussed elsewhere in this tutorial. Potentially can achieve 300+:1 video compression rates in relatively simple algorithmic way. Superiority over MPEG for low bit rates is a point of controversy. Used in Indeo Video Interactive.
