Abstract
A video encoder for encoding a video into a data stream using motion compensated prediction for inter predicted blocks, comprising a hypothesis number control, configured to control a number of prediction hypotheses of the inter predicted blocks within a predetermined portion of the video to meet a predetermined criterion.
Claims12
Video encoder (10) for supporting multi-hypothesis motion compensated prediction, configured to
- use, for n-th hypotheses of inter prediction block, a motion vector accuracy which depends on n.
Video decoder (20) for supporting multi-hypothesis motion compensated prediction, configured to
- use, for n-th hypotheses of inter prediction block (80), a motion vector accuracy which depend on n.
Method for encoding for supporting multi-hypothesis motion compensated prediction, comprising
- using, for n-th hypotheses of inter prediction block, a motion vector accuracy which depends on n.
Method for decoding for supporting multi-hypothesis motion compensated prediction, comprising
- using, for n-th hypotheses of inter prediction block (80), a motion vector accuracy which depend on n.
A non-transitory digital storage medium having a computer program stored thereon to perform the method for encoding for supporting multi-hypothesis motion compensated prediction, comprising
- using, for n-th hypotheses of inter prediction block, a motion vector accuracy which depends on n.
