AI Technical Summary

Technical Problem

Existing video encoding technologies are difficult to effectively utilize intra and inter prediction when compressing video signals, resulting in low encoding efficiency, especially in high resolution and high frame rate video scenarios, where bandwidth and storage requirements are still high.

Method used

The processing circuit is used to realize the combination of intra-inter prediction modes. By encoding the combination of inter prediction and intra prediction of the current block, the position-dependent prediction combination (PDPC) technology is used to exclude motion correction based on bidirectional optical flow, and adjacent samples are selected for combination to reconstruct the samples of the current block.

Benefits of technology

Improves the efficiency of video encoding, reduces bit rate, reduces bandwidth and storage requirements, and achieves higher compression rates especially in high resolution and high frame rate video scenarios.

Abstract

Various aspects of the present disclosure provide methods, devices, and computer-readable storage media for video encoding. In some examples, the video encoding device includes a processing circuit. For example, the processing circuit is configured to receive a current block; encode prediction information of the current block into a video bitstream, wherein the prediction information indicates an intra-frame-inter-frame prediction mode, and the intra-frame-inter-frame prediction mode uses a combination of intra-frame prediction and inter-frame prediction of the current block; wherein the result of the inter-frame prediction is used to be combined with adjacent samples of the current block to reconstruct at least one sample of the current block during decoding, and exclude motion correction based on bidirectional optical flow from the inter-frame prediction of the current block, and the adjacent samples are selected based on the position of the at least one sample.
