Video encoding and decoding with improved error resilience

摘要

A sequence of digital images is encoded into a plurality of encoding units. An image portion is encoded by motion compensation with respect to a reference image portion indicated by an item of motion information. A motion information predictor is determined among a set of motion information predictors and the item of motion information is encoded with respect to the motion information predictor. It is determined to encode the motion information predictors of an encoding unit using either a first encoding mode, which provides encoded data efficiently compressed but not parseable by a decoder in case of losses in the bitstream, or a second encoding mode which provides encoded data less efficiently compressed but systematically parseable by a decoder even in case of losses in the bitstream.
