Abstract

The invention relates to a coding code rate adjusting device and method and electronic equipment, belongs to the technical field of communication, and aims to enable the coding code rate of a transmitting end to adapt to the change of a wireless transmission state more quickly, further improve the quality, stability and reliability of wireless video transmission, avoid the situation that a pictureis interrupted or unsmooth, and improve the user experience. The code rate adjusting device comprises an obtaining module used for obtaining the transmission state of each layer during wireless videotransmission; and the coding code rate adjustment module is used for dynamically adjusting the coding code rate based on the transmission state of each layer acquired by the acquisition module.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to an encoding rate adjustment device, method, and electronic equipment. Background technique [0002] Wireless video transmission is a hot spot in the current video application field. However, the inherent characteristics of wireless channels make it impossible to perform stable and reliable wireless video transmission. In order to improve the stability, reliability and quality of wireless video transmission, an existing solution is to adjust the coding rate of the sending end according to the feedback of the application layer protocol, such as Real-time Transport Control Protocol (RTCP). [0003] However, in the process of implementing this application, the inventors found that: the existing solution has a relatively large delay in adjusting the code rate, cannot respond quickly to changes in wireless transmission status, and the user experience is not good, ...
