A live broadcast signal source inductless switching control method and control system

Abstract

The invention discloses a live broadcast signal source inductless switching control method and a control system, wherein, the method comprises the following steps: A. the encoding parameter of the original live broadcast signal source is set in an encoder and the decoding parameter of the original live broadcast signal source is sent to a terminal; B. the encoder encodes the live video stream in the original live broadcast signal source and sends it to the terminal, and the terminal decodes and plays the data output from the encoder; C. whether the live broadcast management background sends out switching instruction is checked, if not, step B is executed; if yes, step D is executed; D. the terminal keep playing the original live broadcast video stream, and the live broadcast server retrieves the encoding and decoding parameter of the new live broadcast signal source; E. the encoding parameter of the new live broadcast signal source is set in the encoder, and the decoding parameter of the new live broadcast signal source is sent to the terminal; F. the encoder encodes the live video stream in the new live broadcast signal source and sends it to the terminal; G. the terminal decodesand plays. The invention can smoothly switch to a new live broadcast signal source for playing, avoids the phenomenon that the terminal is subjected to blurred screen and black screen or can not play,and improves the user experience.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a control method and a control system for non-inductive switching of live signal sources. Background technique [0002] In the prior art, smart TVs, smart phones, computers and other terminals can all be connected to a live signal source, so as to obtain a live video stream of the live signal source, so as to play the video images of the live video stream. Wherein, the live signal source generally includes a live TV program or a live network video, and the like. [0003] In the prior art, during live broadcast, first, the encoder encodes the live video stream in the live signal source; then, sends the encoded data to the terminal; finally, the terminal decodes and plays the received data. [0004] The streaming media transmission protocols used in the live broadcast technology mainly include rtmp, http, hls and rtsp. No matter which transmission protocol is...

Problems solved by technology

[0006] Since the encoding parameters and decoding parameters corresponding to the live broadcast signal source are set before the live broadcast starts, during the live broadcast process, if the original live broadcast signal source is switched to a new live broadcast signal source, the original encoding will continue to be used after switching. Parameters and decoding parameters, and the original encoding parameters and decoding parameters may not match the new live signal source, so the terminal may have blurred screen, black screen or can not play, you need to exit and reopen the live channel on the terminal to start playing The new live signal source, the smoothness of live signal source switching is low, the user experience is poor, and eventually leads to the loss of users
