Problems solved by technology

[0004] In the process of realizing the embodiment of the present invention, the inventor found that in the existing fast channel switching process, the unicast media data received by the terminal may be insufficient, which affects the continuity of the user's viewing of live program content; or, the unicast media data received by the terminal There may be too much unicast media data, which not only makes the time delay for end users to watch live programs longer, but also causes a waste of FCC server bandwidth resources
Therefore, in the prior art, during the fast channel switching process, the transmission efficiency of unicast media data is low

Abstract

The embodiment of the invention provides a transmission method of media data, a network-side apparatus and a communication system, wherein the transmission method of the media data comprises the steps of: determining a predicted time length required for completing the channel switching by a terminal when receiving a channel switching request sent by the terminal; determining a starting internal coding frame according to the predicted time length, wherein the starting internal coding frame is a starting frame corresponding to unicast media data to be sent to the terminal; and sending the unicast media data cached after the starting internal coding frame is determined to the terminal, and stopping sending the unicast media data to the terminal when a unicast media data packet currently sent to the terminal is same as a first multicast media data packet received by the terminal from a multicast source. The embodiment of the invention is beneficial for improving the sending efficiency of the unicast media data in the fast channel switching process.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of Internet TV, and in particular to a media data transmission method, network side equipment and communication system. Background technique [0002] In the Internet Protocol Television (IPTV for short) system, live programs are transmitted by multicast devices in the form of multicast, and only the content of the live programs selected by the user will be forwarded to the terminal used by the user (such as: a set-top box )superior. The user channel switching process usually includes three stages: the user sends a channel switching request to the multicast device through the terminal, the terminal obtains the multicast address from the multicast device and receives the multicast data, the terminal confirms receipt of the first complete I frame and starts Play the channel's live program content to the user. It can be seen that the user channel switching process takes a long time. ...
