> What you need to do is resize 720P to D1, encode/decode, then resize D1
Erm, I think that sorta defeats the purpose of 720P encoding wouldn't it? The descaling at the first stage would result in a net loss of information which cannot be recovered; However, if you just want a effective SD resolution scaled to 720P using bicubic scaling or its variants, then yes it is maybe possible - the DSP utilization at a VBR H.264 encode of D1 high motion scene itself goes up to about 76-85%, with the VICP co processor being on. Scaling should be able to fit into this MIPS budget However, doing native 720P encode/decode on the C6P+ is next to impossible I think with the DM6446 based on the MIPS numbers - TI has released the 6467 to meet this niche (can do 720P encode/decode and 1080i encode/decode) Jerry
