Live broadcasting method and device and terminal

Abstract

The application provides a live broadcasting method and device and a terminal. The live broadcasting method includes the following steps: acquiring the evaluation data in an evaluation interval, wherein the evaluation data includes the number of data packets in a host cache acquired when the time points in the evaluation interval meet the data acquisition condition; analyzing the evaluation data to obtain the data packet accumulation result of the host cache in the evaluation interval; determining a code rate adjustment strategy based on the data packet accumulation result, wherein the code rate adjustment strategy indicates to increase or decrease the code rate; and adjusting the code rate of the host according to the code rate adjustment strategy so that the host can compress the live stream generated by the host according to the adjusted code rate and obtain and store data packets in the host cache. The code rate can be adjusted automatically according to the accumulation of data packets in the host cache. Live broadcasting of higher quality can be provided on the basis that smooth live broadcasting is ensured.

Description

technical field [0001] The present invention relates to the field of live broadcast technology, and more specifically, to a live broadcast method, device and terminal. Background technique [0002] Live broadcast refers to the process in which the host end compresses the live stream to obtain data packets, and then pushes the data packets to the server, so that the audience can obtain the data packets from the server in real time for viewing. Among them, the anchor end can be considered as the generator of the live stream during the live broadcast process, and the viewer end can be considered as the receiver of the live stream during the live broadcast process, and the live stream can be audio and video data, etc. [0003] Because the live broadcast process involves the transmission of live streams, the live broadcast process is closely related to the network conditions of the anchor and viewers. For example, when the network condition of the host end and / or the viewer end ...

AI Technical Summary

Problems solved by technology

For example, when the network condition of the host and / or audience is poor, there is often a problem of unsmooth live broadcast

At present, in order to solve this problem, it is usually to set a fixed small bit rate for the host end to realize the compression of the live stream. In this way, the compressed live stream will be smaller in size and occupy less network resources. It is convenient to improve the efficiency of network transmission and make the live broadcast smoother; however, although this method can make the live broadcast smoother, it often reduces the clarity of the live broadcast and cannot guarantee a good enough live broadcast quality
