One of the patents appears to be 7,310,374, which does include method claims:
1. A method of encoding a picture in an image sequence, comprising:
dividing said picture into a plurality of smaller portions, wherein each of said
smaller portions has a size that is larger than one macroblock;
selectively encoding at least one of said plurality of smaller portions at a
time in frame coding mode and at least one of said plurality of smaller portions
at a time in field coding mode; and
selectively encoding at least one block within at least one of said plurality of
smaller portions at a time in inter coding mode.
2. The method of claim 1, wherein at least one motion vector is computed for
said at least one block within at least one of said plurality of smaller
portions.
3. The method of claim 2, wherein said at least one motion vector is spatially
predictive coded for a current block of said plurality of smaller portions.
Another is U.S. pat No. 7,310,375:
1. A method of encoding a picture in an image sequence, comprising:
dividing-said picture into a plurality of smaller portions, wherein each of said
smaller portions has a size that is larger than one macroblock;
selectively encoding at least one of said plurality of smaller portions at a
time in frame coding mode and at least one of said plurality of smaller portions
at a time in field coding mode; and
selectively encoding at least one block within said at least one of said
plurality of smaller portions at a time in intra coding mode.
2. The method of claim 1, wherein said intra coding mode employs spatially
predictive coding for a current block in accordance with a plurality of
neighboring blocks to said current block.
And a third is U.S. Patent No.: 7,310,376:
1. A method of encoding a picture in an image sequence, comprising:
dividing said picture into a plurality of macroblocks, each macroblock
containing a plurality of blocks;
generating a plurality of processing blocks, each processing block being
generated by grouping said plurality of macroblocks as a processing block, said
plurality of macroblocks including a pair of macroblocks or a group of
macroblocks; and
selectively encoding at least one of said processing blocks at a time in frame
coding mode and at least one of said processing blocks at a time in field coding
mode,
wherein said encoding is performed in a horizontal scanning path or a vertical
scanning path.
2. The method of claim 1, wherein said processing block includes a pair of
macroblocks.
3. The method of claim 2, wherein each pair of macroblocks of said image is
encoded from left to right and from top to bottom if said encoding is performed
in said horizontal scanning path, and
wherein each pair of macroblocks of said image is encoded from top to bottom and
from left to right if said encoding is performed in said vertical scanning
path.
4. The method of claim 2, wherein said pair of macroblocks comprises a top block
and a bottom block, where said top block is encoded prior to said bottom block
in said frame coding mode.
5. The method of claim 2, further comprising:
splitting said pair of macroblocks into a top field block and a bottom field
block when said pair of macroblocks are encoded in said field coding mode, and
where said top field block is encoded prior to said bottom field block.
6. The method of claim 1, wherein said processing block includes a group of at
least four macroblocks blocks.
The patents do also include apparatus claims.
