A particular implementation detects scene cut artifacts in a bitstream without reconstructing the video. A scene cut artifact is usually observed in the decoded video (1) when a scene cut picture in the original video is partially received or (2) when a picture refers to a lost scene cut picture in the original video. To detect scene cut artifacts, candidate scene cut pictures are first selected and scene cut artifact detection is then performed on the candidate pictures. When a block is determined to have a scene cut artifact, a lowest quality level is assigned to the block. |
