Embodiment Construction

[0070] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0071] Since the existing IPTV-based playback mode has a data control channel and a data stream channel, the two are relatively independent and have no strict timing relationship. The data reception during mode switching is based on the timing of the data control channel. There may be problems with incomplete data, so there are occasional video fr...

Abstract

The present invention provides a control method and device for IPTV-based play mode switching. The method includes: receiving a mode switch request through a data control channel; the mode switch request is used to request to switch the playback mode from the current first mode to the second mode; according to the address information carried in the mode switch request, through The data stream channel obtains media data from the server; the data control channel and the data stream channel are independent of each other; detect whether the media data is the data corresponding to the second mode; if the media data is not the second mode corresponding data, the media data is discarded until the received media data is the data corresponding to the second mode and decoded. Because the present invention processes the acquired media data before decoding, the problems of stuck and blurred screens during decoding are avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control method and device for IPTV-based play mode switching. Background technique [0002] Internet Protocol Television (IPTV for short) technology is to receive the streaming media data sent by the live server, time-shift server or on-demand server through the network to provide users with live video services, time-shift / review or double-speed playback (Trick playback ) services, on-demand services, etc. [0003] The IPTV middleware injects the stream media data received through the network to the decoder. In this process, two channels will be established, one is a data control channel and the other is a data flow channel, and these two channels work independently. Therefore, the integrity of the data received by the data stream channel cannot be guaranteed. For example, in the process of obtaining time-shifted data from the data stream channel, a data reques...
