Problems solved by technology

[0006] It can be seen that the solution in the related art uses a fixed configuration, so it is difficult to meet the requirements of different terminals and different networks for FCC. At the same time, its synchronization method also relies on a specified video stream (such as RTP), and there are interoperability and performance problems in existing network applications.

Abstract

The embodiment of the invention provides a video playing method and related equipment, and belongs to the technical field of communication. The method is executed by a fast channel switching (FCC) scheduling server, and the method comprises the following steps: receiving a first FCC request message sent by user equipment, the first FCC request message comprising a channel identifier of a target channel; in response to the first FCC request message, generating an FCC parameter, the FCC parameter comprising a target FCC server identifier; returning the FCC parameter to the user equipment; the user equipment is used for sending a second FCC request message to a target FCC server corresponding to the target FCC server identifier, wherein the second FCC request message comprises an FCC parameter; requesting to join a multicast group of the target channel according to the FCC parameter so as to receive a multicast video stream of the target channel from the video multicast source server; and the target FCC server is used for sending the unicast video stream of the target channel to the user equipment according to the FCC parameter.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a video playing method, a fast channel switching FCC scheduling server, user equipment, a target fast channel switching FCC server, and a computer-readable storage medium. Background technique [0002] IPTV (Internet Protocol Television, Internet Protocol Television, also known as Interactive Network Television) widely uses multicast to carry live video services, because the multicast stream received by the client (also known as multicast video stream) It may not be an I frame (intra-frame coding frame, I frame represents a key frame, and only the data of this frame can be completed when decoding), but a B frame (bidirectional predictive interpolation coding frame) or P frame (forward predictive coding frame) , the client needs to wait to receive the I frame before it can decode, so the multicast switching delay is long (for example, more than 2 seconds), w...
