Abstract
The invention discloses a set top box of a digital television. The set top box comprises a video decoder and a plurality of video signal output channels. Each video signal output channel corresponds to a video layer and a processor. The video decoder is used for connecting with all the video layers, and decoded video data are copied to the video layers. The processors are used for receiving video data outputted by the video layers corresponding to the same video signal output channels and perform position processing to generate video signals. The video signal output channels are used for receiving video signals generated by the corresponding processor and transmitting the video signals to the television to display. Homologous output of multiple video signal output ends can be realized, and positions of various video signals outputted in the television screen can be independently adjusted.
Description
Technical field
The invention belongs to Digital Image Processing and video display technology field, be specifically related to a kind of digital TV set-top box.
Background technology
At present Digital Television develop rapidly, the digital cable customers number becomes explosive growth, continuous lifting along with user's request, the most digital TV set-top box all provides a plurality of VT, to different vision signal output formats should be arranged, for example high definition HDMI output and SD AV output.For the user, wish no matter be high definition HDMI output, or SD AV output, hope can both be seen TV programme output.Top box of digital machine adopts the way of output of high definition and SD homology at present, can satisfy user's the demand, but because high definition HDMI output and SD AV output, the TV marginal portion width that is blocked is different, the part picture that can see in the possible high definition HDMI output but can not be seen in SD AV output, for this situation, need set-top box that SD output screen is adjusted, so that the user can see whole picture, but based on existing mode, the output of adjusting SD can have influence on the output of high definition.
Summary of the invention
Technical problem to be solved by this invention is: propose a kind of digital TV set-top box, can satisfy a plurality of VT homology outputs, can adjust separately again each vision signal output position in video screen, solve and to support a plurality of VT homology outputs in the conventional art, can not support to adjust separately the defective of each vision signal output position in video screen.
The present invention solves the problems of the technologies described above the technical scheme that adopts:
A kind of digital TV set-top box includes:
A Video Decoder and a plurality of vision signal output channel;
Each vision signal output channel is to having a video layer, a processor;
A described Video Decoder is used for being associated with all video layers, and its video data that decodes is copied into all video layers;
Described processor is used for receiving the video data of exporting with the corresponding video layer of same vision signal output channel, then carries out the position and processes the generation vision signal;
Described vision signal output channel be used for to receive the vision signal that respective processor produces, and vision signal is delivered to television set shows.
The invention has the beneficial effects as follows: because each vision signal output channel is to having a video layer, a processor, and each processor can carry out independently position processing, therefore a plurality of VT homology outputs can be satisfied, each vision signal output position in video screen can be adjusted separately again.
Description of drawings
Fig. 1 is device architecture figure of the present invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Present embodiment is exported with two vision signals, and one of them is high definition HDMI output, and another describes for SD AV is output as example, and for other two above different video mode signal outputs, settling mode roughly the same.
As shown in Figure 1, for two video layers, one of them is associated with the high definition output channel, is the HD video layer; Another is associated with the SD output channel, is the SD video layer.
For two osd layers, one is associated with the high definition output channel, is high definition osd layer; One is associated with the SD output channel, is SD osd layer.
A Video Decoder is associated with HD video layer and SD video layer simultaneously, and decoded video data copies HD video layer and SD video layer simultaneously to.
For the osd image layers, can create public osd mapping buffer and come to produce the picture data for drawing, then copy respectively the picture data to high definition osd layer and SD osd layer by hardware-accelerated.
Receive and mix the video data that video data that the HD video layer data exports and high definition osd layer are exported by processor 1, mixed video data is processed through the position and is produced vision signal, and this vision signal is delivered to television set high definition HDMI interface from the high definition output channel and carried out the video demonstration.
Receive and mix the video data that video data that SD video layer data export and SD osd layer are exported by processor 2, mixed video data is processed through the position and is produced vision signal, and this vision signal is delivered to television set SD AV interface from the SD output channel and carried out the video demonstration.
Revise the position of HD video data in video screen in the processor 1, can not affect processor 2 positions of SD video data in video screen; The position of SD video data in video screen in the same modification processor 2 can not affect processor 1 position of HD video data in video screen.Can adjust separately again the position of high standard definition output in video screen thereby can satisfy the output of high standard definition homology, solve and to have supported the output of high standard definition homology in the conventional art, can not support to adjust separately the defective of high standard definition position in video screen.
Equally, present embodiment has also solved the homology output of osd screen view data and the problem that the position is adjusted by the synchronous processing of video data and osd screen view data.
Claims (2)
