Reduced-memory video decoder for compressed high-definition video data

摘要

A video decoder for decoding compressed high-definition video data. The video decoder includes a down-converter and an up-converter placed in the decoder's data path to reduce the amount of video data that needs to be stored in frame buffer memory. Reference frame video data is decimated and low-pass filtered by the down-converter for storage in a frame buffer memory. The up-converter uses interpolation and low-pass with high boost filtering to reconstruct the reference frames on-the-fly for use in motion compensated prediction.
