<p>The in loop filter (ILF) system comprises: an input buffer, a memory, a transform and filter unit, and an output buffer. The transform and filter unit advantageously performs video transformation and a filtering on the input data stream. The transformation is perferably performed on a macro block basis. The transform and filter unit interacts with the memory in a unique manner such that the input data required to generate an output macro block can be stored in a line buffer and a local buffer thereby minimizing the number of times the transform and filter unit accesses memory. The output buffer is also used to reorder the macro blocks, as well store processing information necessary for additional processing of the video stream. The present invention also includes novel methods for performing video transformation and in loop filtering.</p> |
