Embodiment Construction

[0031] see Figure 2A , which is a sequence of input symbols encoded using a hybrid binarization scheme for Rice parameters from 0 to 4. As shown in the second column of the table, when the Rice parameter (cRP) is equal to 0, the threshold (cTRMax) is 4, where the truncated Rice binarization is used to encode the input symbols below the threshold; when the Rice parameter is equal to 1 When , the threshold is 8, below which truncated Rice binarization is used to encode input symbols; when the Rice parameter is equal to 2, the threshold is 16, below which truncated Rice binarization is used to encode Encodes the input symbols; when the Rice parameter is equal to 3, the threshold is 32, below which truncated Rice binarization is used to encode the input symbols; and when the Rice parameter is equal to 4, the threshold is 64, below which This threshold is used to encode input symbols using truncated Rice binarization. Furthermore, when the Rice parameter is equal to 0, TR binariz...

Abstract

A method of binarizing an input symbol using a hybrid Truncated Rice / k-th order exp-Golomb binarization scheme with a Rice Parameter includes: determining a threshold; comparing the input symbol with the threshold; constructing a codeword using a Truncated Rice (TR) binarization process for the input symbol when a comparison result belongs to a first type of comparison result; and constructing a codeword with an initial prefix and a suffix for the input symbol when the comparison result belongs to a second type of comparison result; wherein the suffix is constructed using an exp-Golomb binarization process.

Description

【Technical field】 [0001] The present invention relates to the method of binarization and de-binarization of input symbols of digital video or image, and especially relates to a kind of mixed truncated Rice / k-order exponential Columbus binarization scheme with Rice parameters to binarize the input A method of notation and related methods for generating index values ​​from codewords for digital video or image encoding / decoding. 【Background technique】 [0002] Digital television (Digital television) and streaming video technologies have given people access to a wealth of information no matter where they live. While video typically takes up a lot of space, digital compression means that many megabytes of data can be transmitted as stored files as well as real-time data (live streaming). The application of this technology is far-reaching: high-quality live media streaming has presented its latest application in the Middle East, where world-changing events are instantly recorded ...
