Title:
VIDEO CODING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/155334
Kind Code:
A1
Abstract:
The present invention relates to the encoding and decoding of a quantization coefficient group among video compression techniques and, more particularly, to a method for performing encoding and decoding by using a variable-sized quantization coefficient group. A video decoding method, according to the present invention, comprises the steps of: obtaining information of a quantization coefficient group for current inverse quantization; obtaining quantization coefficients through entropy decoding on the current quantization coefficient group; obtaining transform coefficients through an inverse quantization process for the obtained quantization coefficients; and obtaining differential signals through an inverse transform process for the obtained transform coefficients.
