发明名称 Video encoder using a refresh map
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).
