Coding Alternate Fields of an Interlaced Video Format:
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.
Coupling a Field of a Current Frame of Interlaced Pixel Data and Fields of the Frames of Data:
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.
