Description
Technical field
The utility model relates to image display technology, particularly the display technique of game machine vision signal on televisor.
Background technology
Popular in the market game machine generally comprises game host and display.The vision signal of game host output, for different game machines, its signal format difference.Current popular game machine, video signal format mainly contains following several: field frequency 60Hz, line frequency 15kHz, the mixed signal of three primary colours and composite synchronizing signal, i.e. RGB+CS signal; Field frequency 60Hz, line frequency 24kHz, RGB+CS signal; Field frequency 60Hz, line frequency 24kHz, 600 * 400 non-standard VGA signals; Field frequency 60Hz, line frequency 31kHz, 38kHz, 48kHz, 640 * 480,800 * 600,1024 * 768 standard VGA signals.Because the video signal format complexity is various, the game machine of prior art all is game host to be cooperated with the display of special use constitute the game machine product.The ubiquitous problem in international market is the update speed of constantly accelerating with respect to game host at present, the progress of game machine display is but not fairly obvious, when certain class game host is eliminated by market, the ground that display is out of use force, can only eliminate, and the price of game machine display is often far above the price of game host thereupon.Upgrade the game machine product and can increase very big financial burden to the user.And since Hesperian blockade on new techniques, domestic game machine user, and product can not upgrade in time.
The utility model content
The technical matters of all solutions of the utility model is exactly at game machine video signal format complexity, and the shortcoming that game machine display cost is high provides a kind of refuting to connect the various game machines that connect, and shows the televisor of game machine video image.
The utility model solves its technical matters, and the technical scheme of employing is: a kind of televisor, comprise display unit, and the video inputs mouth, central processing unit is characterized in that: described televisor is provided with game machine video interface device; Described game machine video interface device is connected with video inputs mouth and central processing unit;
Concrete scheme is: described game machine video interface device comprises the RGB+CS interface, VGA interface, video switch switch, signal processing circuit and microprocessor; Described RGB+CS interface, VGA interface are connected with the video switch switch; Described video switch switch is connected with signal processing circuit; Described signal processing circuit is connected with the televisor input port; Described microprocessor is connected with signal processing circuit and video switch switch; Described microprocessor through bus is connected with central processing unit;
Above-mentioned televisor display unit is back projection display unit, LCD display unit or PDP display unit.
The beneficial effects of the utility model are, have further expanded the application of televisor, make televisor reduce the cost that gaming machine update is regenerated as the display of game machine.
Description of drawings
Fig. 1 is the circuit block diagram of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
Existing televisor, particularly novel large-screen receiver, as the LCD televisor, PDP televisor and CRT, DLP, LCD, LCOS back projection television etc., its video inputs mouth comprises VGA signal port, YUV (brightness aberration) signal port.These televisors generally all have processing, show field frequency 50～100Hz, the ability of line frequency 15～50kHz standard VGA signal and YUV signal.The utility model makes full use of the powerful signal handling capacity of new television models, on existing televisor, increase game machine video interface device, game machine RGB+CS conversion of signals is become YUV signal, or the corresponding input port that becomes the standard VGA signal to send into televisor the non-standard VGA conversion of signals of game machine processs and displays.Because game machine all has the common simulation Audio output port, can directly be connected with the tv audio interface, the utility model does not relate to its treatment technology.
Embodiment
This example is an example with the CRT back projection television, describes the technical solution of the utility model.
This routine game machine video interface device comprises the RGB+CS interface, the VGA interface, and the video switch switch, signal processing circuit and microprocessor, circuit structure is seen Fig. 1.The RGB+CS interface is used to connect field frequency 60Hz, line frequency 15kHz mixed signal or field frequency 60Hz, and line frequency 24kHz mixed signal, because the RGB+CS signal all is video output signals of early stage game machine product, its load capacity is relatively poor.In order to improve load capacity, this road signal inserts the video switch switch through emitter follower in this example.The VGA interface is used to connect field frequency 60Hz, line frequency 24kHz, 600 * 400 non-standard VGA signals; Field frequency 60Hz, line frequency 31kHz, 38kHz, 48kHz, 640 * 480,800 * 600,1024 * 768 standard VGA signals.The game machine signal is selected through the video switch switch, the input signal treatment circuit.Signal processing circuit is discerned automatically to input signal under microprocessor control, and separates trip, field sync signal from composite synchronizing signal.Microprocessor carries out respective handling according to recognition result control signal treatment circuit, and with the central processing unit of recognition result by bus input back projection television, central processing unit places corresponding work mode according to recognition result with the CRT back projection television.When the signal of input was the RGB+CS signal, signal processing circuit became YUV signal with the RGB+CS conversion of signals, imported the CRT back projection television by the YUV signal port of CRT back projection television and carried out subsequent treatment and demonstration.Non-standard VGA signal for input, signal processing circuit is under microprocessor control, input signal is carried out format conversion make it become the standard VGA signal that the CRT back projection television can receive, the VGA signal port of input CRT back projection television processs and displays.If the signal of input is the standard VGA signal, then signal processing circuit is in pass-through state, and the standard VGA signal directly enters back projection television and processs and displays.Circuit block diagram is seen Fig. 1.
Have in physical circuit to be existent technique, this example only is illustrated with block diagram, for those of ordinary skill in the art, according to the above description, can reproduce the technical solution of the utility model fully, and physical circuit can have various ways.
The foregoing description is the example that the utility model is used on the CRT back projection television, is televisor of LCD, PDP display unit etc. for display unit, and its implementation is similar.
