Abstract
The utility model relates to a set-top box used for multiple TV sets. The utility model comprises a set-top box and a remote controller, wherein the set-top box is provided with a plurality of video output interfaces, the video output is connected with the image input interfaces of a plurality of analog TV sets; the set-top box is provided with a wireless radio frequency receiving device; the remote controller is provided with a wireless radio frequency emitting device, and information is transmitted between the remote controller and the set-top box in a wireless radio frequency method. By means of the utility model, one set-top box can be connected with multiple analog TV sets, and the operation is convenient; besides, the utility model has the advantages of simple structure, convenient connection, low cost and convenient manufacture.
Description
Technical field
The utility model relates to digital TV set-top box, especially for the TV-set top box that is used in combination of simulated television.
Background technology
Simulated television can not receiving digital television signal, after the television digitization, wants to watch digital television program with it, must be equipped with device a---set-top box that can receive and handle digital television signal for it.
In China, many cities digital television program that started broadcasting, the user of Digital Television is more and more, has presented the trend of quick growth.From the use pattern, what present at present all is to be digital TV set-top box of existing simulated television configuration basically, and the mode that makes up with this digital-to-analogue solves the problem that simulated television is watched Digital Television.All-in-one is also rare, and all-in-one also is helpless to solve the problem that existing simulated television is watched Digital Television.Now, what have the above television set of two or two family in the city becomes quotidian thing, and generally except the parlor, the bedroom also can be put one in the family.If one family has only been joined a set-top box, so, just can only on a television set, watch digital television program, see Digital Television in the parlor, just can only see simulated television in the bedroom, the two can't be taken into account.This is a unluckily problem really.At present, two nothing but of the ways that addresses this problem: perhaps, a unique set-top box brought in several rooms back and forth do, perhaps buy many set-top box.But, this is not any good method, do the wiring hell to pay of taking out stitches because bring, several of over-bought can increase family burden again, and, this burden is not only disposable expenditure, comprises also from now in the long-term use that for each set-top box repeats to pay monthly rent and license fee, the expense of use is costliness relatively, from higher aspect, this also is disadvantageous to the development that promotes Digital Television.
Summary of the invention
At the problems referred to above, the application has proposed a kind of TV-set top box that is used for multiple TV set, and this device can provide digital television information to multiple TV set under the situation of a set-top box, and is convenient to operation control.
Another purpose of the present utility model is to provide a kind of TV-set top box that is used for multiple TV set, and this apparatus structure is simple, with low cost, easy to make, can be widely used in existing simulated television and use.
The utility model is achieved in that
A kind of TV-set top box that is used for multiple TV set includes set-top box and remote controller, it is characterized in that:
Set-top box is provided with a plurality of video output interfaces, and its video output is connected in the video input interface of many simulated televisions;
Set-top box is provided with the less radio-frequency receiving system;
Wireless RF transmitter is housed on the remote controller, transmits information with wireless radio frequency mode between remote controller and the set-top box.
The described TV-set top box that is used for multiple TV set, the signal between set-top box and the simulated television both can be the vision signals that is suitable for AV terminal, also can be other signals that Y/C separation signal etc. meets existing standard.
The described TV-set top box that is used for multiple TV set, the set-top box of this device includes video output device, master control decoding device, tuner and remote input units, video output device, tuner and remote input units are connected on the master control decoding device, video output device is provided with a plurality of video output interfaces, by this interface to the television set transmission video signal.
The described TV-set top box that is used for multiple TV set, its master control decoding device can provide video and audio signal to multiple TV set simultaneously, makes that the acceptance of the Digital Television between the different television sets is independently, does not constitute influence and interference mutually.
Because less radio-frequency can not blocked by wall, therefore, set-top box can be placed on any room with television set, can control by one or more remote controller.
The user watches in the hall if desired, the television set in the hall can be opened, and realizes watching by remote controller.Because guidance command transmits by wireless radio frequency mode, can be blocked by wall unlike infrared light, thereby can be easily in any room remote control set-top box.If watch in the bedroom, the bedroom television set can be opened, by remote controller control, realize watching.
By the utility model, one family only need be bought a set-top box, just can connect many simulated televisions, thereby does not need to move set-top box, just can watch digital television program at chummery not.And this TV-set top box is simple in structure, and is easy to connect, with low cost, and it is also convenient to make, and is very suitable for family and uses.
The utility model is by the remote control mode of transformation apparatus top box, and with the video output signals of a set-top box connect get home on all television sets, like this, the people is sitting in any television set in any one room before, just can watch digital television program by the remote controller in starting gently, this TV-set top box only solves the problem that several simulated televisions are watched Digital Television with a set-top box, and a kind of simple and effective solution of cheapness is provided for this class user.
Description of drawings
Fig. 1 overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the structural representation of digital TV set-top box, comprise remote controller, tuner, master control decoding device, video output device, remote input units and simulated television, on the remote controller of set-top box, Wireless RF transmitter is housed, the less radio-frequency receiving system is equipped with in the remote control importation on set-top box, remote controller sends control command with wireless radio frequency mode, and the remote input units of set-top box receives order with the less radio-frequency receiver.Its video output is connected on many simulated televisions.
Set-top box includes video output device, master control decoding device, tuner and remote input units, video output device, tuner and remote input units are connected on the master control decoding device, video output device is provided with a plurality of video output interfaces, by this interface to the television set transmission video signal.
The vision signal output of TV-set top box generally is to export a way word TV signal separately, controls a television set and watches.
In other execution mode, this TV-set top box, its master control decoding device can provide video and audio signal to multiple TV set simultaneously.Make that the acceptance of the Digital Television between the different television sets is independently, do not constitute influence and interference mutually.
