<p>An encoding apparatus for coding digital video signals describing a scene having at least one moving object and a stationary background, the digital video signals being represented by a series of video frames, each video frame being divided into a plurality of coding blocks, having a capability of adaptively selecting one of an intra coding technique and a non-intra coding technique to be applied to each coding block, comprises uncovered area detector for, in responsive to a current frame and the previous and next frames thereof in the digital video signals, detecting an uncovered area representing a portion in the current frame, which used to be hidden behind the moving object in the previous frame but becomes visible after a movement of the moving object between the previous and current frames; and coding mode controller for determining, for each of the coding blocks in the current frame, whether the coding block belongs to the uncovered area or not, and applying the intro coding technique to the coding block regardless of the adaptively selected coding mode. <IMAGE></p> |
