PRESERVING ROUNDING ERRORS IN VIDEO CODING |
摘要 |
An input receives a video signal comprising a plurality of frames of a video image, each frame comprising a plurality of higher resolution samples. A projection generator generates a different respective projection of each of a sequence of the frames, each projection comprising a plurality of lower resolution samples, wherein the lower resolution samples of the different projections represent different but overlapping groups of the higher resolution samples which overlap spatially in a plane of the video image. Inter frame prediction coding is performed between the projections of different ones of the frames based on a motion vector for each prediction. The motion vector is scaled down from a higher resolution scale corresponding to the higher resolution samples to a lower resolution scale corresponding to the lower resolution samples. An indication of a rounding error resulting from this scaling is determined and signalled to the receiving terminal. |
