Abstract
The invention discloses a television (TV) picture split-screen expansion system which comprises a main TV with a picture-in-picture (PIP) function, and an expansion display device connected with a video interface of the main TV. A multiplexing chip Mux used for converting audio and video data decoded by a decoding chip of the main TV into transport stream (TS) data flow through multiplexing synthesis and outputting the TS data flow to the video interface is arranged inside the main TV. According to the TV picture split-screen expansion system, the multiplexing chip Mux is arranged inside the main TV and used for converting the audio and video data decoded by the decoding chip of the main TV into the TS data flow through the multiplexing synthesis and outputting the TS data flow to the video interface of the main TV, then the TS data flow is output to the connected expansion display device through the video interface for being decoded and then output in a split-screen displaying mode, and therefore the display function of the main TV is enhanced, and viewing demands of different people can be met at quite low cost.
Description
Technical field
The present invention relates to a kind of television image split screen expanding system.
?
Background technology
At present, people often can only watch a television image in the section at one time when watching TV.The expanded scope that digital television can be used as computer uses, although its picture-in-picture PIP function can realize showing simultaneously two kinds of different signal pictures, but owing to there is no corresponding expansion display device or device, this function of digital television can not given full play of at present, thereby can not satisfy the demand of viewing and admiring of watching different television images in people's the same time.
Summary of the invention
The object of the present invention is to provide a kind of television image split screen expanding system, it can show the television image split screen, to watch the demand of viewing and admiring of different television images in the same time of satisfying people.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of television image split screen expanding system comprises the main television with PIP function and the expansion display device that is connected with the video interface of described main television; Described main TV is built-in with the audio frequency of its decoding chip decoding, video data by the multiplexed synthetic multiplexed chip Mux that the TS data flow outputs to described video interface that is converted to.
Described video interface is USB, HDMI or VGA interface, and described expansion display device is connected on described main television by USB, HDMI or VGA interface.
Described expansion display device is display, projecting apparatus or digital television.
The present invention is converted to by multiplexed synthesizing the video interface that the TS data flow outputs to main television by audio frequency, the video data of the main television decoding chip being decoded at the built-in multiplexed chip Mux of main television, the expansion display device that outputs to connection by the video interface rear split screen of decoding shows output, thereby strengthened the Presentation Function of main television, satisfied the demand of viewing and admiring of different people with less cost.
Description of drawings
Fig. 1 is the structural representation of the television image split screen expanding system that provides of the embodiment of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.
The multiplexed chip Mux of the present invention by being built in digital television DTV inside by the multiplexed synthetic video interface that the TS data flow outputs to main television that is converted to, then shows output by the expansion display device that video interface the outputs to connection rear split screen of decoding with the audio frequency of main television decoding chip decoding, video data.
Referring to Fig. 1, a kind of television image split screen expanding system comprises the main television with PIP function and the expansion display device that is connected with the video interface of described main television; Described main TV is built-in with the audio frequency of its decoding chip decoding, video data by the multiplexed synthetic multiplexed chip Mux that TS (Transport Stream) data flow outputs to described video interface that is converted to.
Described video interface is USB, HDMI or VGA interface, and described expansion display device is connected on described main television by USB, HDMI or VGA interface.
Television image split screen expanding system workflow of the present invention is as follows:
by being built in the multiplexed chip Mux of main television, to the main television audio frequency, the audio frequency that video decoding chip decodes, video carries out multiplexed, synthesize and be converted to basic TS data flow, pass through USB, HDMI or VGA interface are transported to the TS data flow on the expansion display device that connects, display device is decoded to the TS data flow of inputting, and the Audio and Video data of decoding are exported by screen and loudspeaker, thereby realize that different television signals or identical TV signal split screen that main television is received are shown on the expansion display device of connection.
Described expansion display device can be digital television, display and projecting apparatus etc.
After described expansion display device is connected on main television by USB, HDMI or VGA interface, open the PIP function of main television, by this television set, this expansion display device is identified, the TV signal that by multiplexed chip Mux, main television is received after identification is carried out the multiplexed synthetic expansion display device that the TS data flow outputs to connection that converts to, carries out by output after the decoding of expansion display device the TV signal that split screen shows this input.
The above is only the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (3)
