Abstract
In one embodiment of the method of decoding an encoded video signal including a first frame sequence and a second frame sequence by inverse motion compensated temporal filtering, one or more macroblocks in at least one frame in the second frame sequence associated with a current macroblock in a current frame in the first frame sequence are determined based on information included in a header of the current macroblock. The determined one or more macroblocks are decoded based on the current macroblock and the information, and the current macroblock is decoded based on the decoded one or more macroblocks.
Claims21
A method of decoding an encoded video signal including a first frame sequence and a second frame sequence by inverse motion compensated temporal filtering, comprising:
- determining one or more macroblocks in at least one frame in the second frame sequence associated with a current macroblock in a current frame in the first frame sequence based on information included in a header of the current macroblock;
- decoding the determined one or more macroblocks based on the current macroblock and the information;
- and
- decoding the current macroblock based on the decoded one or more macroblocks.
A method of encoding a video signal by motion compensated temporal filtering, comprising:
- determining one or more macroblocks in at least one frame adjacent to a frame including a current macroblock;
- encoding the current macroblock based on the determined one or more macroblocks to form a first sequence of frames in the encoded video signal;
- encoding the determined one or more macroblocks based on the encoded current macroblock to form a second sequence of frames in the encoded video signal;
- and
- adding information to a header of the encoded current macroblock indicating the determined one or more macroblocks associated with the encoded current macroblock.
