Video Compression: MBONE tools
ivs used Haar transform (1996)
nv likewise non-DCT, but much better for Internet
vic is major advance on ivs, nv
- Abandoned inter-frame coding - packet loss confused
- Uses “Intra-H.261”…..Artifacts, Tiling
- Set (high??) threshold for macroblock updates
- Background process ensures everything updated sometime
- Less cpu-bound than ivs
- Better compression than nv
- Better packet loss tolerance than nv, ivs
