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 invention provides a control method and a control device based on IPTV playing mode switching. The control method comprises the steps of receiving a mode switching request through a data control channel, wherein the mode switching request is used for requesting playing mode switching from a current first mode to a second mode; acquiring media data from a server through a data flow channel according to address information which is carried in the mode switching request, wherein the data control channel and the data flow channel are independent from each other; testing whether the media data correspond with the second mode; and if not, discarding the media data, and performing decoding on the condition that the received media data correspond with the second mode. According to the control method and the control device, because the acquired media data are processed before decoding, problems of standstill and screen blurring in decoding are prevented.

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...
