    • 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.

    • 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.
    • 通过视频解码器减少输入变换块的快速逆变换处理的方法包括确定块类型是零,直流,左和顶之一。 如果不是,则执行逆变换,并且提供剩余视频块作为残差信息。 当块类型为零时,旁路逆变换。 当块类型为DC时,执行DC系数的降低的复杂度逆变换,并且提供单个剩余系数作为残差信息。 当剩余块类型时,执行输入变换块的左列的降低的复杂度逆变换,并且提供单列剩余系数作为残差信息。 当块类型为顶部时,执行顶行的降低的复杂度逆变换,并且提供单行剩余系数作为残差信息。
