Abstract
The utility model relates to television technique, and discloses a CD television combination machine. The technical scheme of the utility model is formed by the method that the CD television combination machine comprises a video channel, a display unit and a microprocessor. The utility model is characterized in that the utility model also comprises a display control device which is connected with the video channel, the display unit and the microprocessor, and the display control device controls the operating state of the display unit according to control signals output by the microprocessor. The utility model has the advantages that not only audio-video normal play can be achieved, but also an image can be closed so as to achieve the purpose that sound can be heard individually, and then the function advantage of a combination product which integrates two functions can be further improved so as to improve the convenience of usage for users. The utility model is especially suitable for the application to a portable CD television combination machine.
Description
Technical field
The utility model relates to TV tech, particularly a kind of combination tv.
Background technology
The combination of combination tv, particularly CD-ROM device and televisor, with its compact conformation, easy to use and just becoming a direction of TV development.This combination tv generally comprises DVD module, audio unit, video channel, display unit and microprocessor.The combination tv that has, its audio unit are HIFI audio unit (audio unit comprises the HD Audio treatment circuit), the high fidelity sound tone signal on can reset stereophonic TV sound accompaniment and the video disc.
The DVD module of today all has the function of multiple form video discs such as DVD playing back, SVCD, VCD, CD, MP3, but the combination tv of prior art is play when only can realize audio frequency and video.When CDs such as CD that puts into absolute music in DVD or MP3, display screen is still in running order, and display screen presents blue background or shows the picture that some are specific, no matter user's happiness is disliked all full-screen panel to be turned off.The uncontrolled combination tv of this display unit had both caused the waste of the energy, had consumed the life-span of display also meaninglessly, also was a kind of functional defect simultaneously.
The utility model content
Technical problem to be solved in the utility model is exactly the uncontrolled shortcoming of combination tv display unit at prior art, provide a kind of can be according to the CD TV unit mahine of optical disc's type or user command control display unit duty.
The utility model solves its technical matters, and the technical scheme of employing is, a kind of CD TV unit mahine comprises video channel, and display unit and microprocessor is characterized in that: also comprise display control unit; Described display control unit is connected with video channel, display unit and microprocessor; Described display control unit is according to the control signal control display unit duty of microprocessor output;
Described display control unit comprises video signal detection circuit and on-off circuit; Described video signal detection circuit input end is connected with video channel, and output terminal is connected with microprocessor; Described on-off circuit control end is connected with microprocessor, and input end is connected with power supply, and output terminal is connected with display unit.
The beneficial effects of the utility model are not only can realize the normal play of audio frequency and video, and can turn off picture, realize listening separately of sound, greatly facilitate user's use, further improved the functionality advantage of two-in-one combination product, for the user has increased the convenience that uses.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The technical solution of the utility model is that display control unit is set in unit mahine.The user can pass through operation push-button, closes the display unit power supply according to the hobby of oneself, realizes independent auditory function.Also can be set to auto state by unit mahine, close or connect the display unit power supply automatically according to the type of video disc.The two-in-one TV (combined system of DVD and LCD TV) that with the display unit is the LCD display unit below is example, and the technical solution of the utility model is described.
Embodiment
This routine display control unit comprises video signal detection circuit and on-off circuit, and the video signal detection circuit is connected with video channel, the vision signal in the video channel is detected, and with testing result input microprocessor (MCU); Microprocessor is according to testing result or user command, to on-off circuit control end output control signal; Power supply is connected with display unit by on-off circuit.
In the setup menu of opening to the user, increase the independent auditory function option switches of sound, freely select the opening and closing of this independent auditory function by the user according to hobby; When this independent auditory function is opened, system can monitor the disc kind of putting into DVD automatically, when the CD of absolute music such as play CD or MP3, owing to do not have vision signal in the video channel, video identification status register SID in the LCD TV Video Decoder (Video Signal IDent) is 0, and the SID here promptly is this routine Video Detection circuit.MCU monitors after this register is 0, and promptly by I/O mouth output control signal, on-off circuit is received control signal, closes the video unit power supply.And the audio unit of LCD TV still is in normal operating conditions at this moment, and the user still can hear the sound in the CD, has so promptly realized listening separately of absolute music CD sound.
When DVD playing back in DVD, VCD CD, vision signal is arranged in the video channel, SID is a non-zero status, and MCU does not have control signal output, and display unit is in normal operating conditions, and combination tv carries out normal audio frequency and video and plays.
The user also can pass through operation push-button, and the combination tv display unit is arranged to closed condition, no matter plays which kind of laser disc or TV programme, and screen does not all have any demonstration, and whole two-in-one TV only has sound playing.This routine circuit structure as shown in Figure 1.
This routine implementation step is as follows:
Increase the independent auditory function option switches of sound in setup menu, whether user's independent auditory function that selects a sound activates;
After auditory function activated separately, system's real-time dynamic monitoring was put into the disc kind of DVD, as monitors when being the absolute music CD, SID return state value 0;
It is 0 o'clock that MCU monitors the SID register value, closes liquid crystal display back of the body lamp by I/O mouth output steering order;
After back of the body lamp was closed, and then MCU control scaler closed the video data of closing screen;
After closing video data, and then MCU closes the power supply of screen module by the I/O mouth;
When monitoring the video disc of putting into DVD is non-absolute music CD, during as DVD, VCD etc., whether closes demonstration to be controlled by combination button by the user, and after MCU received the combination button order that the user sends, the control procedure that closing image shows was the same.
The foregoing description is to be that the combination tv of LCD display unit is that example describes with the display unit.At display unit is that implementation of the present utility model is similar in the CD TV unit mahine of led display unit, PDP display unit, CRT display unit.Independent auditory function of the present utility model is particularly suitable at the portable combined TV and has in the combination tv of HIFI audio unit using.
