Abstract

The invention belongs to the technical field of video encoding and decoding, and particularly relates to a data processing method, a data processing device, a computer readable medium and electronic equipment. The data processing method comprises the following steps: obtaining quantized data obtained by encoding a video image, wherein the quantized data is a numerical matrix comprising a zero value and a non-zero value; obtaining non-zero value position information of the non-zero value in the quantized data, and determining a non-zero region in the quantized data according to the non-zero value position information, the non-zero region being a matrix row or a matrix column in the numerical matrix; performing inverse quantization decoding on the quantized data to obtain inverse quantization data; and performing inverse transformation decoding on the inverse quantization data according to the non-zero region to obtain reconstruction data of the video image. According to the method, thecalculation duration and the calculation capability requirement of inverse transformation encoding can be dynamically reduced according to the distribution condition of the non-zero region in the quantized data, so that the calculation speed can be increased, and calculation resources are saved.

Description

technical field [0001] The present application belongs to the technical field of video encoding and decoding, and specifically relates to a data processing method, a data processing device, a computer-readable medium, and electronic equipment. Background technique [0002] Original video data can be generated after image information is collected, and the data volume of the original video data is generally very large. In order to facilitate the transmission and storage of video data, video codec technology is usually used to compress and encode video data to obtain encoded data, which is transmitted and stored in the form of encoded data, which can reduce the network bandwidth pressure of video data in network transmission. At the same time, the storage space of the video data can be compressed to reduce the cost of data storage. When the video data needs to be played or displayed, the coded data can be decoded and restored to reconstruct the video image and finally obtain t...
