Abstract

The present invention provides an audio/video processing method and device. The present invention relates to an audio/video processing method and device. The method comprises the following steps: receiving remote audio/video data, obtaining video data to be decoded from the remote audio/video data; obtaining a coding table from the video data to be decoded; segmenting the coding table to sub code blocks with a pre-determined quantity according to a retrieval frequency; obtaining a current block value based on the context; dynamically generating the data length value of the video data to be decoded according to the current block value and the sub code blocks; and performing CAVLC decoding of the video data to be decoded according to the data length value to obtain the remote video data in a YUV formula after decoding. The audio/video processing method and device can reduce the resource consumption in the audio/video coding and decoding process and improve the efficiency of the audio/video coding and decoding.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an audio and video processing method and device. Background technique [0002] The interactive transmission of mobile smart terminal information depends on the data transmission of the network. From text to pictures to voice and video, the size of the transmitted data increases exponentially, and the requirements for the network are getting higher and higher. Due to the popularity of the third-generation and fourth-generation mobile communication technologies (referred to as 3G and 4G for short), it provides a basis for mobile terminals to transmit large volumes of data. The peak value of 3G downlink speed can reach 3.6Mbit / s theoretically (some say 2.8Mbit / s), and the peak uplink speed can also reach 384kbit / s. Therefore, if the voice and video data is controlled within this range, the requirement for voice and video interaction between mobile terminals can be met...
