Digital TV set-top box
Technical field
The utility model relates to the digital TV set-top box field, more particularly, relates to a kind of digital TV set-top box that can realize remote wireless monitoring.
Background technology
Along with popularizing of national digital TV signal, digital TV set-top box becomes each family's imperative equipment.In the use of set-top box, after set-top box satisfies the basic audiovisual demand of people, there is increasing user that set-top box is proposed the more function demand.The fast pace of the modern life causes people to begin to be not content with must come the controller top box by remote controller in the parlor, satisfy the various requirement of oneself and want to control the set-top box that is placed in the parlor whenever and wherever possible, want to know the TV programme of every night whenever and wherever possible such as people, perhaps have child's the heads of a family to want the child who knows oneself to watch what program etc. by set-top box just at home now.This a kind ofly can realize easily that the set-top box of Long-distance Control satisfies people's requirement with regard to needing.In the set-top box of prior art, can realize that the set-top box of remote wireless control has adopted the Ethernet interface connection Internet by set-top box to realize mostly, perhaps by the control of short-distance wireless interconnection techniques such as bluetooth, WiFi realization to set-top box.
Realize that by short-distance wireless interconnection techniques such as bluetooth, WiFi scheme to set-top box " long-range " controlled in wireless, maximum shortcoming are exactly to accomplish real long-rangely, and these technical schemes are not very stable for data communication, are interfered easily.The method that connects Internet realization remote wireless control by Ethernet interface has bigger limitation to the residing environment of user, be that set-top box must be online always and will have the Internet network and be attached thereto, not having promptly can't to realize Long-distance Control under the environment of Internet, caused the scope of application limited.
Therefore, but how to solve the limited problem of the scope of application of the digital TV set-top box of remote monitoring, become one of technical problem that current urgent need solves.
The utility model content
The purpose of this utility model provides the wide digital television receiver of a kind of scope of application.
For solving technical problem of the present utility model, the utility model discloses a kind of digital TV set-top box, it comprises power supply, set-top box mainboard, mobile communications network communication module and interface module, described power supply is connected to described set-top box mainboard and mobile communications network communication module respectively, and described mobile communications network communication module is connected with described set-top box mainboard by described interface module.
More excellent, described mobile communications network communication module is one of cdma network communication module, GSM network communication module, TD-SCDMA network communication module, WCDMA network communication module
More excellent, described mobile communications network communication module is the GPRS communication module.
Compared with prior art, digital TV set-top box of the present utility model comprises the mobile communications network communication module, its can be immediately and mobile communications network connect, and owing to mobile communications network covers a wide range, thereby overcome of the restriction of Internet network interface, made the user to monitor set-top box by mobile communications network whenever and wherever possible or the transmit operation instruction the set-top box scope of application.
Description of drawings
Fig. 1 is the block diagram of digital TV set-top box of the present utility model.
Embodiment
In Fig. 1, can realize that the set-top box of Long-distance Control comprises a mobile communications network communication module 11, a power supply 12, a set-top box mainboard 13 and an interface module 14.Power supply 12 is connected to mobile communications network communication module 11 and set-top box mainboard 13 respectively, and it is used to mobile communications network communication module 11 and set-top box module 13 that power supply is provided.Mobile communications network communication module 11 is connected with set-top box mainboard 13 by interface module 14.Mobile communications network communication module 11 is for setting up the communication module of data transmission channel with mobile communications network, it can connect by inserting SIM card and mobile communications network, it can also be the GPRS communication module, is connected to Internet by setting up the GPRS ways of connecting.According to the difference of mobile communications network, mobile communications network communication module 11 can be communication modules such as cdma network communication module, GSM network communication module, TD-CDMA network communication module or WCDMA network communication module.Interface module 14 can be serial line interface, as RS232, USB interface, also can be parallel interface or.Set-top box mainboard 13 is used for some information of Digital Television are handled, and all programme informations that it can will be understood the user and the programme information of the current broadcast of set-top box carry out sending on the mobile communications network communication module 11 by interface module 14 after the data compression process.Mobile communications network communication module 11 connects with mobile communications network, by mobile communications network communicate with user's hand-held mobile terminal equipment or with set up GPRS and be connected, be connected to Internet.
The groundwork principle of this digital TV set-top box is as follows:
User's power-on 12, mobile communications network communication module 11 power on and register mobile communications network success after start working, set up a kind of end and connect to wireless IP.Set-top box mainboard 13 is also set up with the data of mobile communications network communication module 11 by interface module 14 and is connected, and waits for the user instruction that mobile communications network communication module 11 receives at any time.At this moment, the user can set up wireless connections with dial mode by cordless communication network and mobile communications network communication module 11 by hand-held mobile terminal, some simple instructions are sent to mobile communications network by hand-held mobile terminal, this instruction is forwarded to the mobile communications network communication module 11 that is inserted with SIM card by mobile communications network again, mobile communications network communication module 11 receives and this instruction is sent to set-top box mainboard 13 behind the command adapted thereto and handles, set-top box mainboard 13 can be operated accordingly according to the command content that the user sends at this moment, thus control and use set-top box.
In addition, mobile communications network communication module 11 can also be set up GPRS with cordless communication network and be connected, be connected to by the Internet network on the server of set-top box assigned ip, this moment, set-top box mainboard 11 sent to the state information of set-top box on the server of this assigned ip, and the user can check the state of set-top box and carry out Long-distance Control by visit Internet network.
Compared with prior art, DTV STB of the present utility model comprises a mobile communications network communication module 11, its can be immediately and mobile communications network connect, and owing to mobile communications network covers a wide range, thereby overcome the restriction of Internet network interface to STB, so that the user can monitor STB or the transmit operation instruction by mobile communications network whenever and wherever possible. In 3G network, data transmission bauds is fast especially, is more convenient for carrying out between long-distance user and the STB interaction.
