Abstract
The invention relates to a home television-computer networking monitoring system, which comprises a personal computer and a TV set. The home television-computer networking monitoring system is characterized in that: the personal computer converts a digital signal into an analogue signal by a built-in modulation module, and transmits the analogue signal by a network; a monitoring module of the TV set receives the analogue signal and transmits the analogue signal to a built-in demodulation module of the TV set; and the demodulation module converts the analogue signal into the digital signal and displays the digital signal on a TV screen. The home television-computer networking monitoring system can realize the function of monitoring computer operations on the television set to prevent a child from being addicted to online games and browsing negative network information; moreover, monitoring software is run in background without any hint on the computer to ensure certain confidentiality and achieve relatively better monitoring effects.
Description
Technical field
The present invention relates to the surveillance of the technical field of a kind of television set and compunlcation, particularly a kind of home television-computer networking.
Background technology
At present in home network, communicating by letter between TV and computer can only be transmitted or the wireless technology such as UWB by VGA holding wire.Due to the restriction being subject on space, the equipment that VGA holding wire is connected in different rooms needs wiring, extremely inconvenient; And current applications of wireless technology is concealed not in supervisory control system, do not have the effect of monitoring; Communicating by letter between TV and computer, resource that can be shared is also very limited.
Summary of the invention
In view of this, the object of this invention is to provide a kind of surveillance of home television-computer networking, can realize the function of monitoring calculation machine operation on TV.
The present invention adopts following scheme to realize: a kind of surveillance of home television-computer networking, comprise PC and TV machine, it is characterized in that: described PC is changed digital signal through built-in modulation module, form analog signal, by network, send, the monitoring module of TV end receives this analog signal, is transferred to the built-in demodulation module of TV, demodulation module converts analog signal to digital signal again, on TV screen, shows.
In an embodiment of the present invention, described network comprises wireless network or cable network.
In an embodiment of the present invention, also further comprise the mobile phone that is provided with described monitoring module, described mobile phone monitors by GPRS network and television set networking.
In an embodiment of the present invention, described TV facility have picture-in-picture function or split screen function, can monitor sending the multiple pc machine of monitoring request simultaneously.
In an embodiment of the present invention, when described TV machine is connected with PC, be by password authentification.
The present invention is the function of monitoring calculation machine operation on TV, prevents child's enthrallment network game, browse network flame, and monitoring software is at running background, on computer, without any prompting, has certain crypticity, can play good supervision effect.In addition,, by this system, can realize network and the media resource of synchronous Sharing computer on TV.PIP function or the split screen technology of utilizing TV, can realize and monitor many computers on TV simultaneously, or share the network of many computers, media resource simultaneously.

Fig. 1 is structural principle schematic diagram of the present invention.
Fig. 2 is the control flow schematic diagram of the embodiment of the present invention.
Fig. 3 is Principle of Communication schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 1, the invention provides a kind of surveillance of home television-computer networking, comprise PC and TV machine, it is characterized in that: described PC is changed digital signal through built-in modulation module, form analog signal, by network, send, the monitoring module of TV end receives this analog signal, be transferred to the built-in demodulation module of TV, demodulation module converts analog signal to digital signal again, on TV screen, shows.Network protocol stack of the present invention can be wireless network, can be also cable network, and they form local area network (LAN) by network route, and when user opens PC, PC sends monitoring request automatically to TV, after the identification of TV monitoring module, is connected communication with PC.The digital signal that PC produces is a kind of non-modulated, the signal of frequency spectrum since 0.The signal that is generally connected to the demonstration of various device terminal by VGA holding wire from PC is all non-modulated, as PC connects slide projector, shows the PPT document in PC, the signal that just belongs to non-modulated at this moment showing by slide projector on curtain wall.This signal demand is changed through modulation module, forms analog signal, could send by network.In addition, the monitoring module of TV, as server end, can be set up Socket after startup, detects the connection request order in whole family lan, after receiving order, agree to request, bundling port, sends monitor command to PC end, the monitored order of PC termination, determine the port of TV server end, connect with server, after success, just can carry out the mutual of data.The Principle of Communication of whole process based on Socket, and can realize by writing software program.
Specifically, please refer to Fig. 2, Fig. 2 is the control flow schematic diagram of the embodiment of the present invention.After TV start, user selects to monitor accordingly menu, enters monitoring menu and need input password, if password mistake, prompt cipher input error, returns to monitoring menu, and password is correct, enters search condition; In search procedure; if there is no PC in start networking state; TV monitoring module just cannot receive the connection request order of PC; system prompt is without available devices; if have PC in start networking state; TV monitoring module receives after the bind command of PC, accepts request and can connect with PC, and show all PC that detect on screen; User selects the PC that will monitor as required, and now monitoring module can send monitor command to this PC, after the monitoring software of PC takes orders, start to send the signal data of PC, this signal data after modulation /demodulation is processed, on screen with PC simultaneous display.If user thinks another PC to be monitored simultaneously, enter PIP function or split screen function that menu is opened TV, repeat above operation, can realize.Software operation on PC of the present invention is all to process on backstage, on computer, without any prompting, therefore, has certain crypticity, can play good supervision effect.
Continue referring to Fig. 1 and Fig. 3, in figure, PC and TV link family lan (wired or wireless) by network router, and network router is supported UPnP function, and as access point; After PC start, operating system drives monitoring software, by network protocol stack, to TV end, sends connection request order, and the monitoring module of TV end is accepted, after this order, to be connected with PC; When user selects after arbitrary PC option at TV end, monitoring module sends monitoring request command by network protocol stack, and the monitoring software of PC is accepted after this order, can set up and communicate by letter with TV.PC digital signal is changed through built-in modulation module, forms analog signal, by network, sends, the monitoring module of TV end receives this analog signal, be transferred to the built-in demodulation module of TV, demodulation module converts analog signal to digital signal again, finally on TV screen, shows.
It is worth mentioning that, if system of the present invention is in conjunction with telecom operators, TV can also be connected into GPRS network, can also mobile phone be monitored or by mobile phone, TV or PC be monitored, effectively prevent child's enthrallment network game, browse network flame.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
