Description
Technical field
The utility model relates to network communication equipment, relates in particular to a kind of set-top-box for bidirectional that can be used for carrying out between telecommunications, radio and television services provider and the user information interaction.
Background technology
At present, the set-top box device of domestic and international production and selling, mostly be one-way set-top box greatly, its operation principle as shown in Figure 1, the programme information that radio and television local side equipment sends, is converted to the TV function by set-top box and receives the analog signal of playing to set-top box by Hybrid Fiber and Coax Network HFC HFC (Hybrid Fiber Coax) one-way transmission program, and be input to users' television set, thereby realize the digital television function of traditional sense.Concrete shortcoming is as follows:
1, the unidirectional access of hfc plant, by radio and television local side tables of equipment to the transmission program to set-top box
The set-top box of prior art is only supported receiving digital television signal from hfc plant, and promptly set-top box only can satisfy the transmission of unidirectional program, and can't realize the interaction between service provider and the user effectively;
2, can't utilize the hfc plant developing value-added services
Radio and television services provider is as the operator, (especially passes through bidirectional rebuilding) after drop into substantial contribution and set up a cover hfc plant, and hope can provide more business and service for the user, thereby obtains higher commercial return.But be subjected to the restriction of set-top box, be difficult to carry out making functions such as real-time video program request (VOD), web page browsing, network gaming, video voice, and carrying out of these functions must provide reverse channel transmission to satisfy the mutual of information.
At present adopt reverse channel transmission, as the real-time VOD of exemplary system, it mainly relies on old-fashioned telephone network (PSTN) based on the reverse program request problem that set-top box solves real-time VOD system.When the user needs request program, at first by the mode of making a phone call, adopt button to import and select program, after the VOD system reception information, begin broadcast program in real time.This kind technical disadvantages:
1, cost height: realize real-time VOD system, the PSTN phone must be installed, need the program request instruction be sent to real-time VOD server by the PSTN network during request program in addition, need be to telco provider's defrayment.
2, efficient is low: request program need be made a phone call, and system response time is slow, and intuitive and interactivity are relatively poor.
3, poor stability: in a single day telephone wire is usurped, lose very big.
The utility model content
The purpose of this utility model is to solve the transmission that existing set-top box only can satisfy unidirectional program, and can't realize between service provider and the user interactive technical problem, propose a kind ofly can make the set-top box of carrying out the two-way communication of information interaction between telecommunications, radio and television services provider and the user.
For the problems referred to above, can consider from two aspects:
1, increase reverse module, transforming existing one-way set-top box is bi-directional set-top box
Used a large amount of one-way set-top boxes in the market,, will cause the massive losses of radio and television operator if simply change.But adopt the reverse module of external back transfer information, the RS232 serial ports of this module is connected with the RS232 serial ports of one-way set-top box, and oppositely the RJ45 Ethernet interface of module is realized being connected with IP network, thereby constitute backward channel.
2, increase backward channel, make improved bi-directional set-top box can be used for multiple backward channel
But the reverse module of back transfer information is set in the new one-way set-top box that produces, makes one-way set-top box upgrade to bi-directional set-top box.Its inner principle is as above 1 described.
For solving the problem that existing set-top box only can one-way transmission, the solution that the utility model proposes is: construct a kind of set-top-box for bidirectional, it comprises the one-way set-top box that can be connected with the external network signal of telecommunication, but the reverse module that also comprises a back transfer information that is connected with described one-way set-top box, described reverse module can be connected with ancillary equipment.
Reverse module described in the utility model, the RS-232 serial ports that comprises CPU/ single-chip microcomputer, the described one-way set-top box of connection and described CPU/ single-chip microcomputer, the RS232 serial ports of described reverse module is connected with the RS232 serial ports of one-way set-top box, also comprises the 10/100MRJ45 network interface that connects described CPU/ single-chip microcomputer and ancillary equipment.
Wherein, described reverse module and described one-way set-top box can be wholely set, also can the split setting.
Among the utility model first embodiment, described reverse module can be connected with two-way hfc plant by a cable modem; Described one-way set-top box can be connected with the two-way hfc plant signal of telecommunication; Described reverse module and described one-way set-top box can the split settings, and the RS232 interface by standard connects between the two.
Among the utility model second embodiment, described reverse module can be connected with two-way hfc plant by a cable modem; Described one-way set-top box can be connected with the two-way hfc plant signal of telecommunication; Described reverse module and described one-way set-top box also can be wholely set, and the RS232 interface by standard connects between the two.
Described cable modem can be arranged on the inside of described reverse module, also can be arranged on the outside of reverse module.
Among the utility model the 3rd embodiment, described reverse module can directly be connected with the ADSL net; Described one-way set-top box can be connected with the ADSL net signal of telecommunication.
Described reverse module also can directly be connected with Ethernet; Described one-way set-top box can be connected with the Ethernet signal of telecommunication.
The utility model is on the basis of existing one-way set-top box, but the reverse module of the back transfer information of increasing, make set-top box can be used for multiple network, satisfy the transmission of two-way program, thereby realize the interaction between service provider and the user effectively, service provider's developing value-added services provides business opportunity, also can satisfy user's different demands.As adopting the utility model in the VOD system in real time, the user can directly select program, request program, termination program, fast forwarding and fast rewinding program etc. by set-top box remote controller, except that the program request expense, does not increase extra-pay; In the request program process, the VOD system is presented at operating process on the television screen in real time in real time, and the user can arbitrarily operate intuitively; The VOD system all passes through the utility model to authentification of user in real time, has the uniqueness restriction, so fail safe is high.Be that the utility model can make customer using cost reduction, rating efficient and safety in utilization improve.
