Problems solved by technology

[0004] However, since the media data sent by the FCC server to the playback device is not the latest media data of the target live channel, compared to other playback devices that have been playing the target live channel or have completed channel switching based on the head-end response, The playback screen is closer to the video screen forwarded by the headend in real time than the screen played by the current playback device, so that the playback device introduces playback delay after channel switching through the FCC server, which reduces the user experience of the live broadcast service

Embodiment 1

[0045] In order to solve the broadcast delay problem caused by fast channel switching, the embodiment of the present application provides a live service processing method. See Figure 4 , Figure 4 It is a schematic flowchart of a live broadcast service processing method provided in the embodiment of the present application. Depend on Figure 4 The above-mentioned live broadcast service processing method includes the following steps:

[0046] S10. The playback device sends first identification information.

[0047] In some feasible implementation manners, after the playback device completes the fast channel switching based on the server, it may send the first identification information to the server before it performs channel switching again. Here, the first identification information is mainly used to mark the first media data segment in the live media stream of the first live channel. The above-mentioned first live channel is a live channel that is being played after th...

Embodiment 2

[0077] See Figure 5 , Figure 5 It is a schematic structural diagram of a live broadcast service processing device provided in the embodiment of this application.

[0078] Wherein, the device may be located in the above-mentioned server 102, and the device includes:

[0079] The transceiver unit 101 is configured to receive the first identification information sent by the playback device. Wherein, the first identification information is used to mark the first media data segment in the live media stream of the first live channel. The live media stream includes multiple media data segments sent by the headend at multiple time nodes. A piece of media data corresponds to a piece of identification information. The first media data segment is a media data segment played by the playback device after switching from the second live channel to the first live channel.

[0080] The media data fragment determining unit 102 is configured to determine a second media data fragment accor...

Abstract

The embodiment of the present application discloses a method and device for processing a live broadcast service. The method includes: the server receives the first identification information sent by the playback device. Here, the first identification information is used to mark the first media data segment in the live media stream of the first live channel. The server determines the second media data segment according to the first identification information and the cached media data. Here, the time node at which the head end sends the second media data segment is after the time node at which the first media data segment is sent. The server sends the second identification information corresponding to the second media data segment to the playback device to instruct the playback device to start playing the live media stream from the second media data segment marked by the second identification information. By adopting the embodiment of the present application, the playback delay introduced by channel switching can be reduced, and the user experience of the live broadcast service can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for processing live broadcast services. Background technique [0002] With the continuous improvement of user access bandwidth and the continuous enhancement of the performance of playback devices such as set-top boxes, mobile phones, and tablet computers, Internet protocol television (IPTV), which integrates various technologies such as the Internet, multimedia, and communications, has also gained popularity. spread widely. However, because IPTV usually uses video and audio compression coding algorithms in the process of live broadcasting, that is, video pictures are coded into multiple image groups composed of I frames (ie key frames), P frames and B frames, and then form media streams on the network. in transmission. Therefore, the playback device can only decode the packet corresponding to the picture group and play the video content...
