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.

技术领域 FIELD

[0001] 本发明属于数字图像处理与视频显示技术领域,具体涉及ー种数字电视机顶盒。 [0001] The present invention pertains to digital image processing and video display technology, particularly to seed ー STB. 背景技术 Background technique

[0002]目前数字电视飞速发展,数字电视用户数成爆发式增长,随着用户需求的不断提升,目前大多数数字电视机顶盒都提供了多个视频信号输出端,对应有不同的视频信号输出格式,例如高清HDMI输出和标清AV输出。 [0002] the current rapid development of digital television, the number of digital TV users to explosive growth, along with rising user demand, most digital TV set-top boxes offer multiple video signal output, corresponding to different video output format for example HD and SD AV output HDMI output. 对于用户而言,希望无论是高清HDMI输出,还是标清AV输出,希望都能看到有电视节目输出。 For users, expect both high-definition HDMI output, AV output or SD, I hope we can see a television program output. 目前数字机顶盒采用高清和标清同源的输出方式,能够满足用户上述需求,但是由于高清HDMI输出与标清AV输出,电视边缘部分被遮挡宽度不一样,可能高清HDMI输出上能看到的部分画面在标清AV输出上却不能看到,针对这种情況,需要机顶盒对标清输出部分屏幕进行调整,以使用户能看到整个画面,但基于现有方式,调整标清的输出会影响到高清的输出。 Currently STB high definition and output SD homologous to meet the user above needs, but since the high-definition HDMI output and SD AV output, TV edge partially occluded width is not the same, may be a high-definition HDMI output to see the partial screen in SD on the AV output can not be seen, for this situation, the need for standard-definition set-top box output portion of the screen is adjusted so that the user can see the whole picture, but based on existing, adjusting the standard definition to high definition output will affect the output. 发明内容 SUMMARY

[0003] 本发明所要解决的技术问题是:提出ー种数字电视机顶盒,既能满足多个视频信号输出端同源输出,又能够单独调整各视频信号输出在电视屏幕中的位置,解决传统技术中只能支持多个视频信号输出端同源输出,不能支持单独调整各视频信号输出在电视屏幕中位置的缺陷。 [0003] The present invention solves the technical problem: Species STB ー raised, both to meet the plurality of output video signal output terminal homology, but also to adjust the position of the video signal output on the TV screen in the individual, to solve the conventional art can only support a plurality of output video signal output terminal homology, can not support the video signal output individually adjust the position of the defect on the television screen.

[0004] 本发明解决上述技术问题所采用的技术方案是: [0004] aspect of the present invention to solve the above technical problem is:

[0005] ー种数字电视机顶盒,包括有: [0005] ー kinds of digital TV set-top boxes, including:

[0006] 一个视频解码器和多个视频信号输出通道; [0006] a video decoder and a plurality of video signals output channel;

[0007] 每个视频信号输出通道对应有ー个视频层、一个处理器; [0007] Each output channel corresponding to the video signal with a video ー layers, one processor;

[0008] 所述的ー个视频解码器,用干与所有视频层相关联,其解码出的视频数据被拷贝到所有视频层; [0008] The video decoder of ー, dry associated with all video layer, decodes the video data is copied to all the video layer;

[0009] 所述处理器,用于接收与同一视频信号输出通道所对应的视频层所输出的视频数据,然后进行位置处理产生视频信号; [0009] The processor is configured to receive video data of the video output from the same layer of the video signal corresponding to the output channel, and generating a video signal processing position;

[0010] 所述视频信号输出通道,用于接收相应处理器所产生的视频信号,并将视频信号送至电视机进行显示。 The [0010] Video signals output channel, for receiving the respective video signals generated by the processor, and the video signal to the television for display.

[0011] 本发明的有益效果是:由于每个视频信号输出通道对应有ー个视频层、一个处理器,而每个处理器都可进行独立的位置处理,因此可以既能满足多个视频信号输出端同源输出,又能够单独调整各视频信号输出在电视屏幕中的位置。 [0011] Advantageous effects of the invention are: Since each output channel corresponding to the video signal with a video ー layers, a processor, and each processor can be carried out independently of the position of the processing, it is possible to satisfy both a plurality of video signals an output terminal outputting homology, but also to adjust the position of the output video signal of the TV screen separately.

附图说明 BRIEF DESCRIPTION

[0012] 图I是本发明的装置架构图。 [0012] FIG. I is a schematic diagram of apparatus according to the present invention.

具体实施方式[0013] 下面结合附图和具体实施例对本发明作进ー步说明。 DETAILED DESCRIPTION [0013] The following drawings and specific embodiments of the present invention will be further described in conjunction with the intake ー.

[0014] 本实施例以两个视频信号输出,其中一个为高清HDMI输出,另ー个为标清AV输出为例进行说明,针对其他两个以上不同视频信号输出方式,解决方式类同。 [0014] In the present embodiment, two video signal output, wherein a high-definition HDMI output, the other one will be described ー SD AV output to, for example, different video signals for the other two or more output modes, similar solutions.

[0015] 如图I所示,对于两个视频层,其中一个关联到高清输出通道,为高清视频层;另一个关联到标清输出通道,为标清视频层。 [0015] FIG. I, for the two video layers, wherein a definition associated output channel, high-definition video layer; SD associated to the other output channels of standard definition video layer.

[0016] 对于两个osd层,一个关联到高清输出通道,为高清osd层;一个关联到标清输出通道,为标清osd层。 [0016] For osd two layers, associated to a high-definition output channels, high definition osd layer; SD associated to a channel output, to SD osd layer.

[0017] 一个视频解码器同时关联到高清视频层和标清视频层,解码后的视频数据同时拷贝到高清视频层和标清视频层。 [0017] At the same time a video decoder associated with video layer HD and SD video layer, while the decoded video data copied to the HD video and SD video layer layer.

[0018] 对于osd图像层,可以创建公共的osd作图缓冲器来供画图,产生画图数据,然后通过硬件加速将画图数据分别拷贝到高清OSd层和标清OSd层。 [0018] For osd image layer, you can create a common buffers osd plotted for drawing, drawing data is generated, and the hardware acceleration drawing data are copied to the HD and SD OSd layer OSd layer.

[0019] 通过处理器I接收并混合高清视频层数据所输出的视频数据和高清osd层所输出的视频数据,混合后的视频数据经位置处理产生视频信号,该视频信号从高清输出通道送至电视机高清HDMI接ロ进行视频显示。 [0019] and receiving high definition video data and the mixed layer osd HD video layer output data outputted by the video data processor I, after mixing the processed video data to generate a video signal position, the video signal supplied from the HD output channel HD TV HDMI connection for video display ro.

[0020] 通过处理器2接收并混合标清视频层数据所输出的视频数据和标清osd层所输出的视频数据,混合后的视频数据经位置处理产生视频信号,该视频信号从标清输出通道送至电视机标清AV接ロ进行视频显示。 [0020] The video data of the video data processor 2 receives and mix video layer data SD through the output and SD osd layer output video data location process generating a video signal after mixing, the video signal output channel supplied from SD TV ro SD AV connector for video display.

[0021] 修改处理器I中高清视频数据在电视屏幕中的位置,不会影响处理器2标清视频数据在电视屏幕中的位置;同样修改处理器2中标清视频数据在电视屏幕中的位置,不会影响处理器I高清视频数据在电视屏幕中的位置。 [0021] I in high-definition video processor modifying the position data of the TV screen, the processor 2 will not affect the position of the standard definition video data in a television screen; the same position processor 2 to modify the winning definition video data in a television screen, I will not affect the position of high-definition video data processor in the TV screen. 从而既能满足高标清同源输出又能够单独调整高标清输出在电视屏幕中的位置,解决了传统技术中只能支持高标清同源输出,不能支持单独调整高标清在电视屏幕中位置的缺陷。 So can meet the high standard definition homologous output and can be individually adjusted HD and SD output position in the TV screen to solve the conventional technology can only support SD and HD homologous output, it can not support a separate adjustment High SD position in the TV screen defects .

[0022] 同样,本实施例通过视频数据与OSD屏幕图像数据的同步处理,也解决了OSD屏幕图像数据的同源输出和位置调整的问题。 [0022] Also, the present embodiment by a synchronization processing with the OSD video data to the screen image data, but also solve the problem of homologous and output OSD screen position adjustment of image data.
