Description
Technical field
The present invention relates to TV domain, relate in particular to a kind of 2D and turn OSD display packing and system under the 3D video format.
Background technology
The 3D video is becoming more and more universal at present, generally uses 2D to turn the 3D technology in the 3D video technique development primary stage.This technology just can have been watched the 3D video frequency program so that common high definition set top box cooperates one to support 2D to turn the television set of 3D function.Turn in the 3D process at this 2D, the OSD menu on the 3D video is demonstration correctly, and this is the basic function requirement of a qualified high definition set top box.
In conjunction with Fig. 1, have high definition set top box so that the viewing area 10 final output image contents on the television display screen are made of two-layer content: one deck is program video layer 20, and one deck is OSD layer 30(on-screen display, and screen menu type is regulated).The program video layer is display program video content (program video image); The OSD layer is used for showing UI menu (user's operation and information etc.).
In existing high definition set top box, set-top box is jointly to be made of complete programs video layer content and complete UI menu content to the picture material of television set output.Its basic demand to television display is: what is exported only need what show faithfully.Do not consider that fully television set may need to carry out different Graphics Processings according to program video layer content.For example, television set is when using 2D to turn the 3D technology, and the 2D that carries out for the program video layer turns the processing of 3D.The form of supporting 2D to turn the frame of video of 3D mainly contains following 3 kinds: left and right sides form, up and down form and color-difference formats, and the below illustrates respectively:
Left and right sides form: when taking, left frame and right frame all are complete two field pictures, the viewing effect of left two field picture representative left eye, the viewing effect of right two field picture representative right eye, between the two may the location and the difference of angle, but each image can the expressed the video content of non-3D, just when post-production, the width of left two field picture and right two field picture is dwindled respectively half, highly remain unchanged, then synthesize on an image, (only show the program video layer among Fig. 2, not shown OSD layer) as shown in Figure 2.When playing, video frame images after synthetic is sent to television set, image after should synthesizing comprises left two field picture 21 and the right two field picture 22 after dwindling, after television set receives this image after synthetic, this two field picture is split into left two field picture 21 and right two field picture 22, and the width of the left two field picture 21 after will splitting respectively and right two field picture 22 is put and is twice, highly remain unchanged, then the left two field picture after will amplifying, right two field picture played in order goes out, send simultaneously signal of telecommunication control 3D glasses right and left eyes synchro switch, make every two field picture only have an eye seeing, left eye is seen left two field picture, right eye is seen right two field picture, thereby has formed the 3D stereoeffect in people's brain;
Form up and down: for the frame of video of form up and down, it is similar that its 2D turns mode and the left and right sides form of 3D, difference only is, when post-production, in conjunction with Fig. 3, the height of left two field picture and right two field picture is dwindled respectively half, width remains unchanged, then synthesize on an image, the image after this is synthetic comprises left two field picture 23 and the right two field picture 24 after dwindling.When playing, the image that receives is divided equally into up and down left two field picture 23 and right two field picture 24;
Color-difference formats: the formation of the frame of video of color-difference formats and above two kinds of forms have larger difference, the independent formation of one frame video layer content (different colours primary colours) the left frame of one frame (or right frame), when every frame video layer content outputs to successively 2D and turns the 3D television set, display shows left two field picture or right two field picture successively, and be sent to people's right and left eyes with different technologies (polarisation or shutter etc.), form the 3D display effect.
