A method for sending live streaming data, a live streaming acceleration server, and a terminal

Abstract

An embodiment of the present invention provides a method for sending live stream data, a live broadcast acceleration server, and a terminal. The method includes: delaying sending the relay live stream to the terminal, so that the preset delay time for the terminal to receive the relay live stream is t1; If the channel change request sent by the terminal after receiving the relay live stream is received, the sending location of the relay live stream being sent is obtained; according to the sending location, the target data is sent to the terminal in unicast mode; so that all After receiving the target data, the terminal closes the unicast channel and joins the multicast group at the same time, and according to the target data and the relay live stream, combines the multicast stream data to be played with the played unicast stream data The multicast streaming data are connected, and the multicast streaming data is played after a preset delay time t3. The live acceleration server executes the above method; the terminal executes another method. The method, the live broadcast acceleration server and the terminal provided by the embodiment of the present invention reduce the bandwidth consumption of the terminal during channel switching.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of streaming media, and in particular to a method for sending live streaming data, a live streaming acceleration server, and a terminal. Background technique [0002] In the field of IPTV video live broadcast, UDP multicast is usually used to realize user live video. Based on the characteristics of compressed and encoded GOP (Group of Pictures) in UDP multicast video streams, the terminal can only complete the subsequent decoding process after receiving a complete I frame; the waiting time for the video I frame to arrive is usually more than 800 milliseconds (depending on the size of the GOP, the wait The time is different), which is the biggest factor affecting the speed of changing channels. [0003] The current fast channel switching scheme is adopted, and a live broadcast acceleration server is added to the traditional live broadcast network. During the channel switching process, t...

Problems solved by technology

In the process of realizing the present invention, the inventors found that the above-mentioned prior art has at least the following problems: at the stage when the unicast flow and the multicast flow are delivered at the same time, the unicast flow and the multicast flow consume bandwidth at the same time, resulting in a large amount of bandwidth consumption. many
