Abstract
The utility model discloses a set-top box serial number programmer. The programmer includes a main control module which controls the programming of serial numbers, an analog CA card module, a serial port/interface circuit and a serial interface, wherein the analog CA card module is connected with the main control module, and the serial interface is connected to the main control module through the serial port/interface circuit. The set-top box serial number programmer of the utility model has the following advantages that: (1) the CA card of a set-top box is a key component for decrypting program stream, and can realize normal viewing of digital scrambled programs, so a CA card interface is an indispensable interface of the set-top box, while an RS232 serial port, a USB interface and a network card interface belong to data service interfaces and are not indispensable, and therefore, the CA card interface of the set-top box can be adopted to realize the programming of the serial numbers, and the problems in the prior art can be solved, namely, the object of programming can be achieved, and cost can be reduced as much as possible; (2) a self-provided power source is not required, and therefore, hardware cost can be saved, and the adaptive capacity of the set-top box serial number programmer is improved; and (3) a variety of serial interfaces can be added on the set-top box, such that the extension of various functions of the set-top box is possible.
Description
Technical field
The utility model relates to a kind of sequence number fever writes, especially programming serial number of set-top box device.
Background technology
Along with the universal and development of digital television techniques, top box of digital machine has become the necessary equipment in many families parlor.Set-top box is a kind of conversion equipment that digital television signal is converted to analog signal, its receives the reduction of decoding of the image of digitalization compressed and voice signal through network, produce video and the voice signal of simulation, provide high-quality TV programme by television indicator and stereo set to spectators.
Sequence number of set top box is a carrier of set-top box monomer information, is the sign of set-top box uniqueness.At aspects such as set-top box production, set-top box use, set-top box users management, set-top box service management, set-top box maintenances, vital effect to be arranged all.Therefore set-top box must be with sequence number of set top box.
At present a large amount of sequence number of set top box burning modes of using be by set-top box self with the RS232 serial ports operate, the USB interface that also can carry by set-top box, perhaps the network interface card interface carries out the programming of sequence number, and for the consideration of cost optimization, set-top box should reduce parts inessential, that be of little use as far as possible.So just produced a contradiction, if when set-top box is not with RS232 serial ports, USB interface, network interface card interface, the programming of sequence number will become a difficult problem.Be with RS232 serial ports, USB interface, network interface card interface if set-top box just increases for the burning sequence number, this does not meet the theory of cost optimization.
The utility model content
The utility model proposes a kind of Novel STB sequence number fever writes for the contradiction of above-mentioned existence.
The design that the utility model is taked is:
A kind of programming serial number of set-top box device, the main control module of control sequence programming, simulation CA card module, serial interface circuit, serial line interface; Simulation CA card module is connected with main control module, and serial line interface is connected to main control module through the serial interface circuit.
Preferably, also comprise power supply changeover device, simulation CA card module provides voltage by power supply changeover device to the serial interface circuit.
Preferably, described serial interface circuit is MAX 232 chips, and serial line interface is the RS232 interface.
Preferably, described serial line interface is the RJ45 interface.
Preferably, described serial line interface is USB interface.
In sum, the utlity model has following significant beneficial effect:
(1) the CA card of set-top box is the critical component of deciphering program stream, realize normally watching of digital interference program, the CA card interface is the requisite interface of set-top box, and RS232 serial ports, USB interface, network interface card interface belong to the data service interface, and be not essential, based on this, can utilize the CA card interface of set-top box to realize the programming of sequence number, can solve and run into problem in background technology, can realize the programming purpose, have and reduced as far as possible cost;
(2) use the voltage of set-top box to provide power supply to fever writes, needn't be self-powered, namely saved hardware cost, improved again its adaptive capacity;
(3) described set-top box can increase multiple serial line interface, makes the various functions of set-top box expansion become possibility;
(4) simple for structure, production cost is low, is easy to large-scale production.
