Abstract

Various techniques and tools for coding and decoding interlaced video are described, including (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 a signal 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 various techniques and tools can be used in combination or independently.
