VIDEO ENCODER UTILIZING COLUMNS OF SAMPLES ENCODED BY PREDICTION AND INTERPOLATION

Video signal samples from a video frame are divided into two sets of alternating interlaced columns one sample wide. Each sample from the first set is encoded differentially with a predicted value developed from reconstructed versions of priorly encoded samples from the first set. Each predicted val...

Zusammenfassung:Video signal samples from a video frame are divided into two sets of alternating interlaced columns one sample wide. Each sample from the first set is encoded differentially with a predicted value developed from reconstructed versions of priorly encoded samples from the first set. Each predicted value for a sample of the first set is of the weighted combination type. Each sample from the second set is encoded differentially with a predicted value developed from reconstructed versions of samples from the first set. Each prediction value for a sample of the second set is developed by means of interpolating adjacent reconstructed samples from the first set.
