Abstract
The present invention relates to a method of realizing synchronous monitoring on a plurality of VGA sources of a LCD TV; and resolves the technical problem that the LCD TV designed and produced by the method can be simply operated and set to realize the synchronous block-division display and in-phase monitoring of the VGA signal source outputted by a plurality of computers via a TV set. The technical proposal is realized when the TV set has basic configurations including a liquid crystal display, a VGA port and at least two SCART ports with the support of a TV-set central control unit and a management program. The present invention has the advantages that the TV set, which is designed and produced by using the method, can greatly extend the product functionality and effectively save resources without increasing the production cost.
Description
Technical field
The present invention relates to method that televisor input information source channel is adjusted, selected and switches, particularly for the LCD TV of existing standard interface configuration.A kind of specifically method that on the LCD TV of standard configuration, realizes a plurality of VGA source synchronous monitorings.
Background technology
Existing digital television or LCD TV, input interface dispose the input of conventional arrangement 1 road computer VGA usually, the HDMI input on 1-2 road, and the SCART input port on 1-2 road is met customer need basically in addition.But the part specific user is arranged, have multiple computers in the family, take into account, operate many displays trouble very in the time of work simultaneously.Utilize existing a plurality of input port, can a plurality of computers demonstrations or the image that receives be outputed on the LCDs simultaneously.Then can make things convenient for these special users widely, also make LCD TV expand function.Because the source type of input channel and preset when dispatching from the factory in signal transfer mode; Must match and realize the function of standard interface with the supervisory routine that this machine shows; Cause the user can not adjust and be implemented in a plurality of VGA source synchronous monitorings on the LCD TV voluntarily, thereby wasted resource.
Summary of the invention
The object of the present invention is to provide a kind of method that on LCD TV, realizes a plurality of VGA source synchronous monitorings; Can be by liquid crystal TV set that this method designed or produced through shirtsleeve operation, setting, and the multiple computers outputting VGA information source that realizes the platform televisor on liquid crystal display synchronously the subregion Display Realization keep watch on synchronously.
Overall technology design of the present invention is: a kind of method that on LCD TV, realizes a plurality of VGA source synchronous monitorings is provided.This method be TV set LCDs, VGA interface and at least two SCART interfaces the support of basic configuration and televisor central control unit and supervisory routine under realize that this method may further comprise the steps:
1. be provided with one or authorize some function keys for " the synchronous monitored state of multi-source " key especially, get into running status to the supervisory routine that the control master routine sends interrupt request and calls the picture-in-picture display mode by this key,
2. display screen is divided into the viewing area; The code of each viewing area and institute's corresponding vision signal memory unit address vector memory block correspondence; The code that VGA interface, SCART interface 1 and SCART interface 2 are provided with according to the supervisory routine of picture-in-picture display mode at random and this code the storage unit of corresponding viewing area set up the information interaction agreement
3. each relevant pins of SCART interface 1 and SCART Interface Terminal is defined the address code of pin again according to the pass pin rule of VGA Interface Terminal,
4. under the support of the supervisory routine of picture-in-picture display mode, each interface pin of timesharing scanning will be taken out display reproduction in corresponding display respectively from the VGA signal of different computers again.
Be not affected according to the design of above method and the liquid crystal picture in picture TV set of being produced all functions under the complete prerequisite of basic configuration.The SCART interface remains effective passage that same category of device sends signal.Only receive the supervisory routine operation that just can end the execution of normal procedure after the interrupt request of " the synchronous monitored state of multi-source " key and access the picture-in-picture display mode at central control unit.But the object of operational management has not been to come from the vision signal that user-selected channel and this channel transmission are come, but selected a VGA port, SCART1 port and SCART2 port and the VGA signal of coming by this port transmission.Behind the following definition of this subroutine management, coding, VGA port, SCART1 port and SCART2 port and accordingly pin all with the digital image zone-setting in corresponding display screen district the information interaction relation.The computer picture of coming through different port transmission just can have the zones of different of being permitted of tucking in brilliant screen that is presented at, and has realized the synchronous demonstration of a plurality of VGA signal sources on same TV liquid crystal display.
Good effect of the present invention is: utilize the televisor of this method design and production effectively to have practiced thrift resource not increasing the function of having expanded product on the basis that produces widely basically.
Embodiment
Comprise in the concrete embodiment of the present invention to management pig program send interrupt request and to the picture-in-picture supervisory routine in increase VGA and SCART interface, particularly to the supervisory routine of SCART interface.Mainly the foundation of the information interaction relation between display screen district and the signal source under the effective state of interrupt routine.The main viewing area of picture kind flower not necessarily meets the wish of support under the corresponding relation of setting up at random, so continuous startup " the synchronous monitored state of multi-source " key will be set can forcibly changing display screen district.Can also realize that each interface rotated by the code that is provided with at random in proper order by means of repeatedly pressing of " the synchronous monitored state of multi-source " key, realize each computer picture-display-region territory by turns.
Be provided with in this method or authorize " the synchronous monitored state of a multi-source " key to replace, and selection and conversion that submenu is realized the initial display code of each interface are set with the respective items selected that is arranged in the televisor function menu.
During specific to liquid crystal TV set at present commonly used, on LCD TV, realize being defined as again the SCART interface pin in the method for a plurality of VGA source synchronous monitorings:
The 11st pin of scart terminal is defined as VGA signal green leading foot,
The 7th pin of scart terminal is defined as VGA signal blue signal leading foot
The 15th pin of scart terminal is defined as VGA signal danger signal leading foot
The 8th pin of scart terminal is defined as VGA signal rows synchronizing signal leading foot
The 16th pin of scart terminal is defined as VGA signal field synchronizing signal leading foot.
Realizing on the LCD TV in the concrete design that method instructed of a plurality of VGA source synchronous monitorings can be according to above VGA output port that is connected computer that the definition again of SCART Interface Terminal pin is made in advance and the conversion of signals line between the televisor SCART interface.To make things convenient for the special user to make the trouble of this patchcord.
