Systems and methods for coding alternate fields of interlaced video sequences.

Summary

Lead Inventors: Dimitris AnastassiouDescription: Methods and systems for coding alternate fields of an interlaced video format are described. Systems for arrangements wherein the other fields have already been coded is also described.The system and method comprises of an input means for coupling a field of a current frame of interlaced pixel data and fields of the frames of the data. A storage means is coupled to the input for storing data and for providing data. A block-matching means compares a block of pixel data from current frames and past frames to develop motion vector signals indicative of best-matched blocks of data. A comparator performs multiple mode comparisons of a block of pixel data. An output coupled to the comparator provides the best-mode signals, motion vector signals and pixel error signals of data for transmission to a decoder.The methods and systems provide coding for interlaced video data so as to permit efficient and accurate decoding.
