Description of drawings
Fig. 1 is the structural representation of handheld terminal disclosed in this invention;
Fig. 2 is the flow chart of the display interface of instant playback handheld terminal shown in Figure 1 on computers.
Embodiment
Main design of the present invention is, after the data bitmap boil down to video data stream with the handheld terminal interface, send to computer (PC) side, at this moment, receive the PC of video data stream, only handheld terminal need be seen the video capture device that makes a standard, interface that just can the instant playback handheld terminal.
Below in conjunction with the drawings and the specific embodiments technical solution of the present invention is described in further detail.
A kind of handheld terminal, as shown in Figure 1, comprise the display interface data extracting unit, data compression unit and the data transmission unit that connect successively, the display interface data extracting unit links to each other with the handheld terminal display module, data transmission unit link to each other with outside display system (for example PC), wherein, can adopt communication modes such as USB (USB, Universal Serial Bus), infrared ray or bluetooth between handheld terminal and the outside display system.Introduce the function of each unit below in detail:
The display interface data extracting unit, be used to extract the display interface data of handheld terminal, and the data of extracting are sent to data compression unit, wherein, this unit is used for depositing the buffering area of the interface data that had shown from display module, the display interface data of timing extraction handheld terminal, in this process, the data of display interface data extracting unit timing extraction from buffering area are a width of cloth width of cloth data bitmap, in the present embodiment, in order to satisfy the requirement that image shows, this unit per second extracts 10 secondary data at least, and extraction time is no more than at most 25 times in the per second;
Data compression unit, display interface data (i.e. a width of cloth width of cloth data bitmap) the boil down to video data stream that is used for to receive (promptly can with each width of cloth data bitmap boil down to one frame video), and the video data stream after will compressing sends to data transmission unit, wherein, data compression unit meets the requirement of PC side according to the video data stream of prior art compression, promptly can be transformed into and get final product for the data flow that PC side upper layer software (applications) uses by the PC side, H.263 this data compression unit can be used or video flowing encryption algorithm H.264, also can adopt other any video flowing algorithm in other embodiments;
Data transmission unit, be used for sending video data stream to the PC side, in this example, after handheld terminal and PC side connect by USB interface, video data stream after this unit will compress sends to PC and gets final product, in other embodiments, handheld terminal also can be with after PC sets up bluetooth and is connected, and the video data stream after this unit will compress sends to PC.
After above-mentioned handheld terminal and PC connect, the Windows operating system of PC side thinks that by enumerating the handheld terminal that inserts is a video capture device, on the other hand, after handheld terminal is judged enumeration succeeds (be PC with handheld terminal as video capture device), handheld terminal extracts the data bitmap of display interface, sends to the PC side after according to prior art the data bitmap that extracts being compressed into video data stream again; After PC receives video data stream, the standard device read-write mode reading video data stream by Windows operating system, and offer the upper layer software (applications) of PC side, be used for instant playback, record a video or take pictures.This process is divided into following steps particularly, as shown in Figure 2:
Step 201, handheld terminal and PC connect;
In the present embodiment, handheld terminal and PC side connect by USB interface, in other embodiments, handheld terminal can also and the PC side between adopt communication modes such as infrared ray, bluetooth.
After the handheld terminal that step 202, physically connected are gone into was enumerated, what identification inserted was video capture device, sets up data transmission channel between handheld terminal and the PC subsequently;
In this step, PC can be identified as video capture device with handheld terminal by the driving of video capture device.
In this step, handheld terminal is deposited from its display module in the buffering area of the interface data that had shown, extracts the display interface data, wherein, the interface data of extraction is a data bitmap, in the present embodiment, the number of times that the handheld terminal per second extracts data is at least 10 times, and is no more than 25 times.
In this step, handheld terminal can be compressed into video flowing with the interface bitmap according to existing video-frequency compression method.
Step 206, PC is the video data stream that receives, and offers the upper layer software (applications) of PC as the video capture device data of standard, is used for showing, recording a video or take pictures.
From the foregoing description as can be seen, the data that the PC side is obtained in the technical solution of the present invention are from the display interface of handheld terminal, the data of the handheld terminal camera that obtains with PC side in the prior art are compared, interface operation that can the instant playback handheld terminal, and the display interface that can preserve handheld terminal in real time is in order to reference to research.In addition, because technical solution of the present invention is transferred to the PC side with the display interface of handheld terminal in the mode of video flowing, therefore the PC side does not need special software to cooperate demonstration, the video capture device that only needs handheld terminal to be invented a standard just can show, records a video or take pictures, thereby as can be seen, the operation of technical solution of the present invention is very simple and efficient.
The above embodiment is the preferred embodiment that proves absolutely that the present invention lifts, and protection scope of the present invention is not limited thereto.Being equal to that those skilled in the art are done on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
