Embodiment

[0029] The live channel real-time video navigation method realized by the IP channel proposed by the embodiment of the present invention, in the actual application process, specifically includes the following steps:

[0030] 1. Video synthesis of live channel, including the following operations

[0031] 1. Video decoding of each live channel: Decode the IP stream or TS stream of the live channel and restore it to an uncompressed picture stream.

[0032] 2. Reduce the resolution of the picture stream: For each picture in the picture stream of each live channel, some pixels are extracted horizontally and vertically through a certain algorithm to form a new picture. Different degrees of extraction are performed according to the size of the live channel in the navigation video on the screen.

[0033] 3. The synthesis of the navigation video. At a certain point in time, the pictures (at the same time point) with reduced resolution of multiple live channels are spliced ​​into a lar...

Abstract

The invention provides a live channel real-time video navigation method realized through an IP channel, and belongs to the field of video navigation. The method solves the problem that an existing video navigation technology occupies too many physical channel resources, and comprises the steps that when a user watches a live broadcast channel, a video navigation key is pressed down; the set top box acquires the synthesized video stream from the cloud through the IP channel and plays a group of live channels; judging whether a live channel to be played is in the current group of playing channels or not; and if so, selecting a required live broadcast channel from the current group of channels, and playing the live broadcast channel in a full-screen manner after selection is confirmed, otherwise, switching from the current group of playing channels to the next group of playing channels until the current group of playing channels is switched to the group of live broadcast channels where the required live broadcast channel is located, selecting the required live broadcast channel, and playing the live broadcast channel in the full-screen manner after selection is confirmed. The navigation video is transmitted through the IP channel, and does not occupy a physical channel.

Description

technical field [0001] The invention relates to a video navigation technology, in particular to a real-time video navigation method realized through an IP channel, aimed at broadcasting of a live channel based on a DVB channel or an IP channel. Background technique [0002] Currently, operators that provide live TV services generally have hundreds of live TV channels. The way for users to select a live channel is either to increase or decrease the channel, or to directly input the channel number, or to use textual navigation information, which is very unintuitive. Video navigation technology has appeared in the radio and television operator market before, that is to synthesize multiple live channels into one video in 3*3 or 3*4 format, and broadcast it as one live channel. This method needs to occupy channel resources. If there are 240 TV channels, 7 physical channels need to be occupied by using the 3*3 synthesis method. At present, cable TV basically only has about 80 p...
