Video decoding with error detection and concealment
A system and method of decoding input video information is disclosed which includes performing error detection for each video block of a frame, determining whether a scene change occurs for the frame, and when an error is detected in a video block, performing spatial concealment by concealing error of the erroneous video block using neighboring video information within the frame when the erroneous video block is intraframe encoded or when a scene change is detected for the frame, or performing temporal concealment by replacing the erroneous video block with a reference video block from a reference frame when the erroneous video block is interframe encoded and when a scene change is not detected for the frame. The method may further include detecting false frames based on comparing current and new frame number and picture order count values of a new slice.
