Abstract
Disclosed in the utility model is a serial port-to-ethernet conversion communication system that comprises a unidirectional set-top box and an EOC terminal. The unidirectional set-top box is used for connection with a television set and obtaining instruction information by the television set; and the EOC terminal is connected is connected with an ethernet network by a coaxial cable. A first RS232 serial port module is arranged in the unidirectional set-top box and is connected with a central processor; a second RS232 serial port module is arranged in the EOC and is connected with a control module. A sending out port of the first RS232 serial port module and an incoming port of the second RS232 serial port module are in bidirectional communication connection; and an incoming port of the first RS232 serial port module and a sending out port of the second RS232 serial port module are in bidirectional communication connection. And the second RS232 serial port module receives information from the first RS232 serial port module and converts the information into one in an EOC data format. According to the serial port-to-ethernet conversion communication system disclosed by the utility model, a unidirectional set-top box can be utilized to carry out modification; and an effect of interactive transmission of a bidirectional set-top box can be realized.
Description
Technical field
The utility model relates to digital TV data conversion field, and relating in particular to a kind of serial ports for the television set passback changes the ether communication system.
Background technology
The digitized process of radio and television has entered the new stage of pushing forward comprehensively, and national cable digital TV development is swift and violent, and digital television is also constantly popularized.Common broadcast formula digital television only can passively be accepted digital television signal, and the programme content that provides is comparatively single.And what can make really that Digital Television has powerful glamour is " interactive TV ", i.e. interactive digital television.The interactive digital TV function provides the two-way interactive function of user and local side, and the user can also realize multiple business such as program guide, video request program except watching common digital television program.Existing one-way set-top box with serial ports can not carry out interactive transmission, if change existing one-way set-top box into bi-directional set-top box, will need substantial contribution, and causes the idle of a large amount of one-way set-top boxes, is unfavorable for taking full advantage of of resource.
Therefore, utilizing existing one-way set-top box and it is transformed, and reach the effect that bi-directional set-top box can carry out interactive transmission, is the technical problem that those skilled in the art need solution badly.
The utility model content
The purpose of this utility model provides a kind of serial ports changes the ether communication system, can utilize one-way set-top box and it is transformed, and reach the effect that bi-directional set-top box can carry out interactive transmission.
To achieve these goals, the utility model provides a kind of serial ports to change the ether communication system, is used for connecting television set and Ethernet, comprises one-way set-top box and EOC terminal; Described one-way set-top box is used for connecting television set, and obtains command information by television set; Described EOC terminal is connected with Ethernet by coaxial cable; Be provided with a RS232 serial port module in the described one-way set-top box and be connected with its central processing unit, be provided with the 2nd RS232 serial port module among the described EOC and be connected with its control module, the outgoing port of a described RS232 serial port module is connected with described the 2nd RS232 serial port module incoming port both-way communication, and the incoming port of a described RS232 serial port module is connected with described the 2nd RS232 serial port module outgoing port both-way communication; Described the 2nd RS232 serial port module is the EOC data format from described RS232 serial port module reception information and with above-mentioned information translation.
Preferably, the grounding ports of a described RS232 serial port module is connected with described the 2nd RS232 serial port module grounding ports both-way communication.
Compared with prior art, serial ports provided by the utility model changes the ether communication system, according to the propelling along with unification of three nets, the EOC end product is popularized, and also be provided with the situation as the serial ports of universal debugging interface on the EOC end product, utilize EOC terminal and one-way set-top box to form serial ports and change the ether communication system, from television set, obtain command information, and be the EOC data format with above-mentioned information translation in the serial port module in the EOC terminal, send to Ethernet; And the ingenious data of having utilized the two-way interactive function low code stream of Digital Television, the characteristics that do not need the very high network bandwidth, serial ports by one-way set-top box and EOC terminal is finished data dissemination, realized the interactive transmission of Digital Television, make the client to send instruction by the remote controller of television set, finish the function of two-way interactive, therefore, the serial ports that provides that the utility model provides changes the ether communication system, can utilize one-way set-top box and it is transformed, and reach the effect that bi-directional set-top box can carry out interactive transmission.
Description of drawings
Fig. 1 is the structured flowchart that a kind of serial ports that the utility model proposes changes a kind of embodiment of ether communication system.
Embodiment
The purpose of this utility model provides a kind of serial ports changes the ether communication system, can utilize one-way set-top box and it is transformed, and reach the effect that bi-directional set-top box can carry out interactive transmission.
