Embodiment
Display system described in literary composition is the realization to described video information processing method and video broadcasting method, below narrates basic display system and the more specifically realization of system thereof.
With reference to figure 1, the basic structure block diagram that this figure is this display system, display system consists of main frame, choosing mouthful module, control module, display module.Display module consists of two above display units, and control module consists of input interface, processing unit, storage unit, two above output interfaces.Main frame and choosing mouthful module provide a road current video information and choosing mouthful instruction to the input interface of control module respectively, processing unit, according to the choosing mouthful movable output interface current video of instruction process current video information providing information, is also supplied with the video information that fixes of inactive output interface history by the storage of storage unit.
The video information that fixes refers to circulate and read the video information of anchor-frame from storage unit, by output interface, supplies with display unit, makes the latter maintain a static picture.
Current video information is while being provided by video card, this main frame refers to by PC and device that wherein video card forms jointly, at this moment use a control enclosure as control module, the video output interface of video card is connected with the video input interface of this control enclosure, a choosing mouthful module is connected with control enclosure by USB interface, control enclosure is supplied with digital video information by each video interface to each display unit arranged side by side, the video information that in control enclosure, processing unit is also processed video card input is so that it mates with display unit, and this processing can comprise frame per second, picture pixel, convergent-divergent, trimming, video format etc.
Now, because this control enclosure fixedly mates with display unit, the versatility of video output interface is inessential, can select LVDS.For adapting to the video card of different PCs, the video input interface of control enclosure can be supported various video form, and while comprising HDMI, control enclosure increases audio frequency output.The storage of this memory storage is to take buffer memory as object, only needs several two field pictures of storage, during storage, does not compress.Because the read-write flow of this memory storage is larger, select DDR3.Processing unit is read and write storage by read-write controller, can select dual-port read-write memory.Processing unit main body can realize by FPGA or DSP+FPGA mode.
If directly give each display unit supplying video information with special many output video card, omit above-mentioned control box, the fore-end of PC and this video card forms described main frame, and the rear end part of this video card forms described control module.PC is supplied with choosing mouthful instruction as the part of control module by the data command interface of this video card in this video card.
A kind of easy implementation is provided again.Can in ordinary PC, pass through USB external-connection displayer, basic display unit and external slave display form described display unit, PC inside arranges video processing program as control module process information, it is responsible for according to choosing mouthful command assignment video information, comprise by USB and send corresponding video information to slave display, easier method is slave display can be made as to the demonstration that fixes all the time.Latter two pattern has been simplified the signal flow of display system but has been reduced adaptability, and below narration be take control enclosure pattern as main.
