Low-Cost Video Encoder

A method for encoding a new unit of video data includes: (1) incrementally, in raster order, decoding blocks within a search window of a unit of encoded reference video data into a reference window buffer, and (2) encoding, in raster order, each block of the new unit of video data based upon a decoded block of the reference window buffer. A system for encoding a new unit of video data includes a reference window buffer, a decoding subsystem, and an encoding subsystem. The decoding subsystem is configured to incrementally decode, in raster order, blocks within a search window of a unit of encoded reference video data into the reference window buffer. The encoding subsystem is configured to encode, in raster order, each block of the new unit of video data based upon a decoded block of the reference window buffer.
