ABSTRACT:
In block based video compression, a frame is divided into blocks which define a tiling pattern. The tiling pattern is varied from frame-to-frame to prevent an accumulation of errors which tend to appear at tile edges and can increase over time when using block-based compression. In a preferred embodiment, a normal frame is padded by a border all around the normal frame size. The padding is operable to extend any blocks around the periphery of the image frame which might be smaller in dimension than the standard blocks, such as those within the interior of the frame, such that they can be treated by the block-based compression systems as full size blocks.
