Problems solved by technology

[0004] In the process of realizing the above-mentioned mosaic TV service conforming to the DVB standard, the inventor found at least the following problems in the prior art: Although the standard TV picture is composed of a plurality of small video preview pictures, after being processed by the mosaic generator, the standard The small video preview screen in the TV screen can no longer be divided. When the terminal uses the mosaic TV service flow for navigation, it cannot manage each small video preview screen separately, resulting in poor operability of the terminal and bringing users bad experience

Embodiment 1

[0041] This embodiment discloses a mosaic TV service implementation method, the implementation method is executed by the front end of the operator, such as figure 1 As shown, the method includes the following steps:

[0042] 101. Scale down the TV program video streams of each channel, that is, the standard video streams for users to normally watch TV programs, to obtain corresponding small video streams. When standard TV programs with N (N is a positive integer) channels are scaled down and multiplexed into one channel for transmission, N small video streams will be obtained, and the picture of standard TV programs on each channel is reduced to the original 1 / N times the size.

[0043] 102. Multiplex the obtained small video streams into one mosaic TV service stream. If the reduced small video streams of N channels of standard TV programs are obtained, multiplex the obtained N small video streams into one mosaic TV service stream.

[0044] The multiplexing into one mosaic ...

Embodiment 2

[0050] This embodiment specifically describes the implementation method of the mosaic TV service.

[0051] combine figure 2 , specifically providing an implementation method of the mosaic TV service, and the implementation method is executed by the front end of the operator. Such as figure 2 As shown, the method includes the following steps:

[0052] 201. Scale down standard TV program video streams on each channel for users to normally watch TV programs at the front end of the operator, that is, compress the frames of each standard video in equal proportions, and obtain corresponding small video streams. When a standard TV program with N (N is a positive integer) channels is scaled down and multiplexed into one channel for transmission, N small video streams will be obtained, and the size of each small video stream is 1 / of the size of a standard TV program N times (considering the influence of the program content and the efficiency of the encoder, the size of the compress...

Embodiment 3

[0063] This embodiment discloses a mosaic TV service implementation method, the implementation method is executed in the user terminal, such as image 3 As shown, the method includes the following steps:

[0064] 301. The user terminal receives the mosaic TV service stream sent by the front end of the operator.

[0065] 302. Demultiplex the received mosaic TV service stream combined into one serial into each small video stream. When the front end of the operator multiplexes N (N is a positive integer) small video streams into one mosaic TV service stream, the user terminal can demultiplex N small video streams.

[0066] 303. The demultiplexed small video stream picture is compressed, and the small video picture is compressed or enlarged according to the video ratio, so that the picture is a small video preview picture of a preset size.

[0067] 304. In the terminal (such as: a set-top box), include a background layer for displaying the background color, a video layer for dis...

Abstract

The embodiment of the invention discloses a realization method, a realization device and a realization system for mosaic television services, which relates to the technical field of televisions and solves the problem that a terminal has poor operability to a preview picture of each small video in a picture in the prior art. A video stream of a television program of each channel is used to reduce the picture size of a video of the television program according to the proportion to obtain small video streams corresponding to the television program of each channel; all the small video streams are multiplexed into at least one path of mosaic television service flow; and the mosaic television service flow is sent to the terminal. At least one mosaic television service flow issued by a front end is acquired; at least one small video stream is demultiplexed from the mosaic television service flow; a picture of the small video stream is adjusted to the preset size; and the adjusted picture of the small video stream is displayed in the picture. The embodiment of the invention is mainly applied to a television program system to realize the respective management of the terminal to the preview picture of each small video.

Description

technical field [0001] The present invention relates to the technical field of television, in particular to a method, device and system for realizing a mosaic television service. Background technique [0002] The mosaic TV service is to divide the screen of the display device into several small areas, and each small area displays a full-motion video of a channel digital TV program. The user can move and select a certain full-motion video through the remote control, and then choose to watch the full-motion video. Linked standard TV channels. Compared with the electronic program guide (EPG) that transmits text information, the mosaic TV service has better interactivity and friendliness because it can provide users with program previews of TV channels. [0003] In a mosaic TV service conforming to the digital television broadcasting (DVB) standard, it is first necessary for the operator to be equipped with a relatively complex mosaic TV generator at the front end, and use the ...
