Processing of video signals prior to compression |
摘要 |
Video analysis processing upstream of a compression encoder provides for use by the encoder flags such as a shot change flag; a frame/field based encoding flag; a 3:2 pull-down flag; a 25/24 telecine flag; a luminance fade flag and a flash effect flag. The encoder makes use of these flags in its coding decisions to improve coding efficiency or to reduce artefacts. |
