<p>A channel adaptive video transmission system and method. A system (10) is provided that includes: a variable length decoding system (VLD) (14) for generating header codes and discrete cosine transform (DCT) run length codes from the compressed video signal; a DCT codes marking system (16) for inserting markers into the DCT run length codes to define marked DCT coefficient segments; and a bit stream processing system (18) that determines whether to keep marked DCT coefficient segments based on current channel conditions.</p> |
