Embodiment Construction

[0035] Such as figure 1 As shown, it is a flowchart of an embodiment of the media stream encoding method of the present invention, and the method includes:

[0036] Step 101, the wireless network controller counts the audience rating information of at least two channels and sends it to the video headend;

[0037] The paging channel or broadcast channel requires the terminal using a certain MBMS service to send a reply message. After receiving the reply message sent by the terminal, the radio network controller (RNC) calculates and updates the audience rating information of the above channel in real time, and sends To the head end of the video; the ratings information here uses the concept of average ratings, that is, the ratio of viewers who watch a certain column (or a certain channel) in a certain period of time to the total number of TV viewers in the analysis area;

[0038] Step 102, the video head-end analyzes the received audience rating information of each channel, and...

Abstract

The embodiment of the invention relates to a media stream encoding method, a media stream encoding device and a media stream encode switching system, wherein the media stream encoding method comprisesthe following steps: the audience rating information of at least two channels is analyzed, so as to generate an analysis result; the frame-to-frame value of frames to be inserted in a video stream isadjusted according to the analysis result; and the video stream is encoded according to the frame-to-frame value of the frames to be inserted, so as to facilitate the encode switching to the video stream. The media stream encoding method, the media stream encoding device and the media stream encode switching system greatly reduce the standby time of reference images, thereby greatly decreasing the time delay of the channel switching.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a media stream encoding method, device and switching system. Background technique [0002] With the deployment of the third generation mobile communication technology (3G) and the integration of fixed and mobile networks, mobile video will gain more development and application. business, this mobile video service can be implemented in three different ways: based on satellite networks, using digital terrestrial broadcasting and using mobile networks. [0003] Among them, the way of using the mobile network is mainly based on the multimedia broadcast and multicast service ( MBMS) streaming media technology mainly uses streaming media technology to promote mobile TV as a data service. This method can take advantage of the strong interactive capabilities of communication networks to provide users with more personalized services without changing th...
