Description
Affiliated technical field
The present invention relates to a kind of digital television system, particularly a kind ofly carry out mutual digital television system by the mobile communication channel.
Background technology
Along with the popularization of Digital Television One-to-All Broadcast and popularizing of set-top box, utilizing digital channel to carry out data service will become the new business opportunities of television operator.Utilize the both-way communication means to carry out full interactive application, as video request program, audience rating statistical, guess on the net, send short messages mutually, online chat, interactive advertisement, network gaming, online business, online finance etc., will make data service obtain great success.
Above-mentioned interactive service all needs the information return path, and the digital television broadcasting net has multiple mode to carry out the passback of data, and as PSTN MODEM, CABLE MODEM, xDSL, ETHERNET, its shortcoming is that speed maybe needs to carry out the network rebuilding slowly.
Summary of the invention
Purpose of the present invention is exactly will provide a kind of to carry out mutual digital television system by the mobile communication channel, can must not carry out carrying out the data interaction business apace under the situation of the network rebuilding.
When realizing purpose of the present invention, taked following technological means:
This digital television system includes digital TV front-end machine room local side 1, mobile communication network headend room 2, apparatus of digital television receiving 3, wireless communication base station 4, CATV net 5.
Include mobile channel modulator/demodulator 7, primary processor in the apparatus of digital television receiving 3 wherein and show 8, user's ascending control information is gone out by mobile channel modulator/demodulator 7 modulate emission by primary processor and after showing 8 mobile communication signaling process.
This transmits and receives and handle through wireless communication base station 4, then user's ascending control information is passed to mobile communication network headend room 2, data switching exchane by mobile communication network headend room 2 carries out the information processing conversion, wireless communication base station 4 is given in passback then, and launch by wireless communication base station 4, give digital TV front-end machine room local side 1.
Digital TV front-end machine room local side 1 wherein has the mobile communication data receiving function, therefore can receive the also ascending control information of process user, sends digital television business broadcasting then.
The digital television business broadcast singal enters apparatus of digital television receiving 3 by CATV net 5, also include television channel demodulator 6, infrared receiving terminal 9, Infrared remote controller 10 in the described apparatus of digital television receiving 3, television channel demodulator 6 becomes the digital television business broadcast singal binary data stream of base band, and send into primary processor and show 8, at primary processor and show in 8 that this data flow is separated multiple connection to be handled, tell three data flow: audio frequency, video and data, audio stream is wherein exported simulated audio signal through decoding; Wherein video flowing forms vision signal one through decoding, and data flow wherein becomes visual information with data transaction through primary processor and show 8 CPU analyzing and processing, forms vision signal two; Vision signal one and vision signal two are after synthesizing, the output analog video signal, and show, the user is after seeing this visual data information, its feedback information sends by Infrared remote controller 10, receive by infrared receiving terminal 9, and convert infrared signal to the signal of telecommunication and send into primary processor and show in 8, primary processor and show that 8 handle and after interactive application handles by CPU, user's feedback information is carried out the mobile communication signaling process, modulate and be transmitted into wireless communication base station 4 by mobile channel modulator-demodulator 7 again, this transmits and receives and handle through wireless communication base station 4, then user's ascending control information is passed to mobile communication network headend room 2, data switching exchane by mobile communication network headend room 2 carries out the information processing conversion, and wireless communication base station 4 is given in passback then, and is launched by wireless communication base station 4, give digital TV front-end machine room local side 1, thereby form closed loop.
Because in the present invention, the information of uploading in the data interaction business is to be undertaken by the mobile communication channel, and at present, mobile communication is quite universal, service price is also more and more lower such as in China, its overlay area has surpassed the zone that the digital cable TV net is covered, therefore just can present digital cable TV net not transformed, and cost of access is also low.Native system has demonstrated fully the characteristics of asymmetric transmission, the downlink information that promptly contains much information is undertaken by the very wide digital cable TV net of frequency band, and the mobile communication channel of the little uplink information of amount of information by the frequency band relative narrower carry out, so the speed of data interaction business is fast.And, therefore can not produce interference between the two because up-downgoing is different communication modes.
