摘要： The present invention relates to a video encoder (ENC) for encoding frames (FR) of a video signal before transmission, said video encoder (ENC) including an encoding decision unit (EDU) for deciding which kind of coding will be used for each data of said frame (FR) in an encoding unit (ENU). Said video encoder (ENC) further implements a freshness map calculation unit (FMCU) for calculating, throughout the time, for each data of said frame (FR), a corresponding freshness value (FV) taking into account Intra and Inter prediction mechanisms, independently from a calculation of a distortion. Said freshness value (FV) express on which degree encoded data (ED) are relying on previously transmitted data and said freshness value (FV) is used by said encoding decision unit (EDU).

摘要： The present invention relates to a video decoder for decoding a bit stream corresponding to pictures of a video signal. The invention is such that, motion vectors having values coded at a nominal resolution in the bit stream, said video decoder includes a rounding unit for rounding decoded nominal motion vectors to a resolution different from the nominal resolution in a way that minimizes the error accumulation along prediction path by assigning to rounded successive motion vectors along the prediction path, successive values such that their average value is equal to the value of the nominal motion vector.
