AI Technical Summary

Technical Problem

Existing compression technologies fail to effectively utilize the characteristics of different compression techniques when encoding video sequences, resulting in low encoding efficiency and an inability to achieve optimal encoding quality for each part of the video sequence.

Method used

The signal is decomposed into multiple components by using a multi-coder selection unit, and each component is encoded using a different encoding algorithm. The bit rate allocation of each component is determined by optimizing the cost function, and the encoding process is optimized by combining neural networks or deep learning algorithms.

Benefits of technology

It enables the use of the best combination of compression techniques in each part of the video sequence, optimizing encoding performance and quality while maintaining reverse compatibility, thus improving encoding efficiency and quality.

Abstract

Controlling a bit rate for encoding a signal. The signal is encoded using at least two different encoding algorithms. A total bit rate is allocated to at least two components of the signal. A first component of the signal is to be encoded using a first encoding algorithm. A second component of the signal is to be encoded using a second encoding algorithm.
