VVC interframe coding unit prediction mode early decision and block division early termination method

Abstract

The invention discloses a VVC inter-frame coding unit prediction mode early decision and block division early termination method. The method comprises the following steps of analyzing the motion changes between video frames; comparing the rate distortion cost between the prediction modes in an inter-frame coding unit with the coding depth of 1, and comparing the selected optimal mode with the coding cost of the inter-frame prediction mode in the subsequent coding depth; for coding units meeting conditions, skipping the check on the coding cost of the inter-frame prediction mode directly, so that the calculation complexity is reduced. In addition, the optimal division size of the current coding unit is predicted through the ratio relation between the current coding depth of the coding unit,the selected optimal prediction mode and the rate distortion cost between the prediction modes, and the recursive division process with extremely high computational complexity is avoided by terminating the division of the coding units in advance, so that the calculation complexity of the coder is reduced, the time consumption of the coder can be effectively reduced under the premise that the video coding quality is not influenced, and the coding efficiency is improved.

AI Technical Summary

Benefits of technology

This patented technology helps compare two videos with each other by comparing their rates at varying levels of compression (CR) level or resolution. By analyzing how well they match up together during playback on an electronic device's screen, we are able to identify areas where more data needs less processing power than what was previously needed for better performance. It also suggests adjustments made based upon these results to enhance image quality while maintaining good overall visual experience. Overall, this technology improves encoding efficiency and reduces redundancy computation compared to traditional methods like motion compensation techniques.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving how well these advanced visual media formats like High Definition TV or Ultraviolet Vision Film (UMTV) display images without compromising quality while maintaining efficient processing capabilities at reasonable costs. Current compression techniques such as Huffman codes require significant computing resources, leading to slow convergence times even further adding extra delays. Interpolated decodable motion compensating (IMV)-HEVC proposals provide solutions through specific models called Multiplex Model Units (MMUs) and Fast Computational Structured Expansion Groups (SEQEGS). These enhancements aim to reduce computation requirements compared to older approaches, resulting in faster convergence rates and greater flexibility towards future changes in picture quality.
