Video Inter-Frame Predictive Coding Method Based on Reference Slices

Abstract

The invention discloses a video inter-frame prediction coding method based on a reference slice. The video inter-frame prediction coding method is based on reference content management and an optimization scheme of the reference slice, can collect more information under the condition of limited DPB capacity, so that a current coding block can find a matching block with higher probability. Eventually, the video inter-frame prediction coding method has the overall effect of effectively improving the efficiency of video coding under the circumstance of slightly increasing complexity of coding and decoding ends.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to a video interframe predictive coding method based on a reference slice. Background technique [0002] In recent years, with the rapid development of the Internet, there are more and more requirements for video applications on the Internet, and the amount of video data is very large. In order to transmit in the Internet with limited bandwidth, the first problem that must be solved is the problem of video compression and encoding. . [0003] The video coding standards that have been formulated all belong to the hybrid video coding framework. The so-called hybrid video coding generally consists of the following parts: prediction (Prediction), transformation (Transform), quantization (Quantization) and entropy coding (Entropy Coding). The prediction is generally divided into intra prediction and inter prediction. A video frame that can only use an intra-frame predicti...

Problems solved by technology

[0009] 1. Multi-reference frame selection and management in HEVC adopts the same processing scheme for different video contents, which is not adaptive

[0010] 2. Adaptive reference frame selection based on video content requires pre-analysis of the video to be encoded, which is difficult to apply to streaming media encoding scenarios

[0011] 3. Improved reference frame list sorting based on the distribution of referenced content is greatly affected by the video content to be encoded, and additional reference frame memory is required for auxiliary processing

When the capacity of the reference buffer (Decoded Picture Buffer, DPB) at the decoding end is limited, the content in multiple reference frames is repeated, there is redundancy, and the utilization efficiency of the buffer is not high, which limits the further performance improvement of video coding
