摘要： A method of reducing processing of fast inverse transform of an input transform block by a video decoder includes determining whether a block type is one of zero, DC, left, and top. If not, the inverse transform is performed and a residual video block is provided as residual information. When the block type is zero, inverse transform is bypassed. When the block type is DC, reduced complexity inverse transform of a DC coefficient is performing and a single residual coefficient is provided as residual information. When the block type is left, reduced complexity inverse transform of a left column of the input transform block is performed and a single column of residual coefficients is provided as residual information. When the block type is top, reduced complexity inverse transform of a top row is performed and a single row of residual coefficients is provided as residual information.

摘要： 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.
