<P>PROBLEM TO BE SOLVED: To provide techniques and tools for coding and decoding interlaced video. <P>SOLUTION: The techniques and tools include (1) hybrid motion vector prediction for interlaced forward-predicted fields, (2) using motion vector block patterns, (3) selecting between dominant and non-dominant polarities for motion vector predictors, (4) joint coding and decoding of reference field selection information and differential motion vector information, (5) joint coding/decoding of macroblock mode information for macroblocks of interlaced forward-predicted fields, (6) using signal transmission of the number of reference fields available for an interlaced forward-predicted field, and (7) deriving chroma motion vectors for macroblocks of interlaced forward-predicted fields. The techniques and tools can be used in combination or independently. <P>COPYRIGHT: (C)2011,JPO&INPIT |
