The systems and methods can be used to transcode 5 or convert input signals having certain characteristics into desired output signals having different characteristics requirements. The systems and methods are based on compressed domain processing, partial decoding-reencoding, or full decoding-reencoding with side information, depending on the specific characteristics of the input and desired output signals.WO 2007/115133 PCT/US2007/065554 1/6 FIG. 1: TRANSCODING SYSTEM Input Input Video Output Video Otu Input Bitstreamn Bitstream Otu Video PP Transcoder P.
