Description

Method, system, device and set top for displaying multiple channel information in the same screen

Technical field

The present invention relates to the field of digital multimedia, and more particularly to a method, system, device and set top box for displaying multiple channel information in the same picture. Background technique

In Internet Protocol Television or Interactive Personal Television (IPTV) and Digital Television (DTV), there is an Electronic Program Guide (EPG) display that simultaneously displays multiple channel programs on the same screen. Means, generally referred to as Mosaic. The business experience provided by the mosaic is: dividing the display screen into multiple areas, each area independently displaying a program of one channel, the user can watch the programs of each channel in these areas, and select the area corresponding to a certain channel through the remote controller. After clicking, the program of the corresponding channel is viewed in full screen. Compared with the channel program composed of text and pictures, the mosaic can display the program being played by each channel in real time, providing users with more intuitive and attractive program preview function.

The specific implementation of the mosaic is: The set top box simultaneously receives the media stream of each channel program, decodes each media stream, and divides the display screen into multiple regions, for example, Ν Μ 区域 regions, each region independently displaying a channel program, The set top box combines the contents of the media streams of the plurality of channel programs and simultaneously displays them on the screen, and the user can watch the programs of the respective channels through the small screen of each area. After the user determines the program to be viewed, the channel corresponding to the program is selected by the remote controller. Clicking on the area, the set-top box receives the command input by the user, stops receiving other media streams other than the channel, and plays the program of the channel selected by the user to the user in full screen.

In the existing scheme for implementing mosaic, the set-top box needs to receive the media streams of multiple channels at the same time, which will lead to the excessive cost of the overall implementation scheme, and the realization of the set-top box is greatly complicated. In the IPTV network, when implementing a 3 x 3 mosaic service, the set top box needs to receive the media stream at 9 multicast ports, and the decoding chip of the set top box needs to decode the received 9 channels of media streams at the same time. If a channel needs to occupy 1.2 to 2.5 megabits per second (Mbps) of bandwidth, a 3 x 3 mosaic service requires an access bandwidth of 10.8 to 22.5 Mbps, which makes it necessary to implement mosaic services in an IPTV network. More transmission resources. In addition, the decoding chip of the set top box can decode the multiple media streams at the same time, and the set top box is required to divide the display screen into regions, and the content of each media stream is combined and displayed on the screen at the same time, so that the complexity of the set top box is very high. High, this will lead to a sharp rise in the cost of the set-top box.

In the DTV network, although the transmission bandwidth is fixed regardless of whether the media stream is transmitted or the multi-channel media stream is transmitted at the same time, the mosaic service does not occupy additional transmission resources, but the mosaic service in the DTV network also needs to be implemented. The set-top box simultaneously receives the multi-channel media stream, and still needs the decoding chip of the set-top box to simultaneously decode the multi-channel media stream, and also needs the set-top box to divide the display screen into regions, and merge the contents of the media streams and display them on the screen, so that The complexity of the set-top box implementation is still very high, resulting in a sharp increase in the cost of the set-top box.
