Abstract
The present invention discloses a digital television system for conducting interaction via mobile communication channels, which comprises a machinery room local side of the front end of a digital television, a machinery room of the front end of a mobile communication network, a digital television receiving device, a wireless communication base station and a CATV network, wherein the machinery room local side of the front end of a digital television and the digital television receiving device both have a mobile communication function. On-line control information of a user can be transmitted from the digital television receiving device and is sent to the machinery room local side of the front end of a digital television via the wireless communication base station and the machinery room of the front end of a mobile communication network. Therefore, the machinery room local side of the front end of a digital television sends out digital television traffic broadcasts. The CATV network is used for sending the on-line control information to the digital television receiving device which is demodulated for displaying video and viewdata information. After the user sees, feedback information can be sent out through the digital television receiving device. Consequently, a closed ring is formed. Under the condition that the reconstruction of the network does not need conducting, the present invention can be used for rapidly conducting data interactive business.
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, be divided into three data flow: audio frequency, video and data, audio stream is wherein exported simulated audio signal through decoding; Video flowing wherein is through decoding, form vision signal one, and data flow is wherein passed through primary processor and is shown 8 CPU analyzing and processing, data transaction is become visual information, form 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, user's 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, 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, 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.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the system block diagram of native system.
Fig. 2 is the apparatus of digital television receiving block diagram.
