Embodiment Construction

[0017] In order to enable those skilled in the art to better understand the content of the present invention, the content of the present invention will be specifically described below in conjunction with the accompanying drawings and specific embodiments.

[0018] The basic flow of program switching provided by the embodiment of the present invention can be referred to figure 1 , mainly including steps:

[0019] A1. Receive a program switching request sent by the terminal, where the program switching request includes an identifier of the program to be switched by the terminal.

[0020] The terminal sends a program switch request to the media control module through the PLAY command carrying the Require: 3gpp-switch-req-sdp identifier and the SDP-requested header field. The program switch request includes the switch program identifier. For example, the program the user is watching is "Sky" , at this time, the user initiates a program switching request and wants to receive the p...

Abstract

The embodiment of the invention discloses a program switching method, a system and a device. The method comprises the following steps: adopting a program switching request sent by a receiving terminal, wherein the program switching request contains a program identification to be switched by the terminal; based on the program identification, judging that the program to be switched is not in a media server which broadcasts programs for the terminal; and based on the program identification, initiating a real-time streaming protocol (RTSP) link establishment request to the media server containingthe program to be switched, so as to realize program rapid switch among different media servers.

Description

technical field [0001] The present invention relates to the communication field, in particular to a program switching method, system and device. Background technique [0002] With the digitization of TV signals, while bringing clear TV programs, it is also necessary to realize fast switching of channels / programs. In the prior art, the fast switching of programs is based on the fact that the content before and after the switching is in the same media server; when the programs before and after the switching are not in the same media server, the switching speed is slow and the user experience is poor. Contents of the invention [0003] In view of this, the present invention provides a program switching method, system and device to solve the problems of slow program switching speed and poor user experience. [0004] A method for program switching, comprising: receiving a program switching request sent by a terminal, wherein the program switching request includes a program ide...
