Embodiment Construction

[0046] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with examples.

[0047] The core content of the present invention is: by establishing and maintaining the control channel between the playback terminal and the media server, the media server can receive the switch command sent by the playback terminal through the established control channel, and control the live broadcast and time according to the received switch command. Switch between live broadcast and time-shift playback, or switch time-shift playback to live broadcast, so as to realize fast switching between live broadcast and time-shift playback.

[0048] like image 3 as shown, image 3 It is an implementation flow chart of the overall technical solution for switching between live broadcast and time-shifted playback in the present invention. The premise of this method is to establish and ...

Abstract

The method establishes control channel between playing terminal and media server. The method also includes following steps: (1) through the said established control channel, the playing terminal sends the received switching command to media server; (2) after receiving the switching command, the media server executes switching between living broadcast and time shifting broadcast. The invention raises switching speed between living broadcast and time shifting broadcast greatly so as to provide better service for user. The invention is in favor of promoting and applying time shifting TV technique.

Description

technical field [0001] The invention relates to the field of network multimedia television, in particular to a method for realizing switching between live broadcast and time-shifted playback. Background technique [0002] As the mainstream TV technology in the existing broadcast TV system, the service provided by live TV to users is one-way. Users can only passively accept the schedule of TV programs and watch the specified TV programs at the specified time. Due to the complexity of the live broadcast bearer network, there are two implementation methods for live broadcast: unicast live broadcast and multicast live broadcast. Among them, in the case of unicast live broadcast, the media server forwards the live data stream received from the live encoder in unicast or multicast mode to the playback terminal according to the playback request received from the playback terminal; in the case of multicast live broadcast, the live broadcast The encoder acts as a multicast source, a...
