1. A multiple description video encoding method comprising the steps of:

  • identifying based on content of a frame at least one region of interest (ROI) in said frame, said frame being one of a plurality of frames comprising a video sequence being encoded in parallel by two motion compensation processes to produce two respective streams to be transmitted to a decoder, each stream including a mismatch signal usable by the decoder to reconstruct a part of the video sequence motion compensated to produce the other stream;

    determining, for said frame, a portion of said mismatch signal that resides outside said at least one ROI; and

    precluding from the transmission said portion.
