Abstract
Methods and encoders for tracing an error in a frame of a video to a subsequent frame of the video. In response to receiving an error notification message indicating an error has occurred in an encoded frame during decode, an encoder obtains: (a) the minimum and maximum horizontal motion vector components for each column of blocks of the frame immediately following the error frame; and (b) the minimum and maximum vertical motion vector components for each row of blocks of the frame immediately following the error frame. A rectangular region of blocks of the frame immediately following the error frame that the error is likely to have propagated to is identified using the minimum and maximum horizontal and vertical motion vector components.
