Title: Qian Tang: Innovator in Adaptive Binary Arithmetic Coding
Introduction
Qian Tang is a notable inventor based in San Jose, CA (US). He has made significant contributions to the field of adaptive binary arithmetic coding, holding 2 patents that showcase his innovative approach to encoding systems.
Latest Patents
His latest patents include a "Context-based adaptive binary arithmetic coding engine." This system comprises a binarization module, a prediction module, and a shifting module. The encoding module is designed to encode symbols using context-adaptive binary arithmetic coding, where the symbols are generated by binarizing a syntax element. The prediction module generates a prediction for the number of renormalizations needed to adjust an interval range when encoding a symbol. The shifting module creates a renormalized interval range by shifting the binarized syntax element R times, where R represents the number of leading zeros before a 1 in the binarized syntax element. The encoding module then encodes the next symbol based on the renormalized interval range.
Another patent by Qian Tang is also titled "Context-based adaptive binary arithmetic coding engine." This system includes a binarization module, an encoding module, and a prediction module. The binarization module binarizes a syntax element and generates symbols. The encoding module encodes these symbols using context-adaptive binary arithmetic coding (CABAC). The prediction module generates a prediction for the number of renormalizations to be performed to adjust an interval range when encoding a symbol. The encoding module encodes the next symbol based on the prediction before the renormalization of the interval range is completed.
