| 摘要 |
The present invention, mainly applicable in streaming and broadcast for TV, video on demand and storing systems, relates to a video encoder (ENC) for encoding frames (FR) of a video signal before transmission, said video encoder (ENC) including a bit rate allocation unit (BRAU) for allocating a bit rate to encoded data in a encoding unit (ENU). According to the invention, this video encoder (ENC) further implements a dependency map calculation unit (DMCU) which calculates, for each data of said frame (FR), a corresponding dependency value (DV) taking into account Intra and Inter prediction mechanisms. This dependency value (DV) expresses on which degree said data will be used in further encoding, the dependency map (DM) being used by the bit rate allocation unit (BRAU). |
