Embodiment
Below in conjunction with embodiment and with reference to accompanying drawing the utility model is further described.
Referring to Fig. 1, a kind of principle of device block diagram that uses a plurality of decryption cards that a plurality of CMMB programs are decrypted.Related terms is explained as follows:
RF IN:CMMB rf input interface;
The TUNER:CMMB tuner;
The USB:USB interface;
USB HUB:USB hub;
TF Cardx8:8 TF card;
TF Readerx8:8 TF card reader;
CPU: microprocessor.
The microprocessor that the present embodiment adopts is with USB interface, and internal memory, and flash memory etc. form the minimum system of microprocessor; The CMMB tuner is supported USB interface simultaneously, and the card reader of TF card is also supported USB interface; Adopt a usb hub that the USB interface of microprocessor is expanded, expand altogether 9 USB interface, one of them is connected with the CMMB tuner, and other 8 connect the TF card reader, and the TF card is inserted in the card reader.Comprise the CMMB rf input interface, rf input interface links to each other with tuner; Comprise 8 TF cards, 8 TF card readers, TF card are inserted in respectively on the corresponding TF card reader; The data that microprocessor obtains tuner by usb hub are dealt in the decryption card and are decrypted, the data flow after obtaining to decipher.
Referring to Fig. 2, a kind ofly use a plurality of decryption cards that the device program decryption that a plurality of CMMB programs are decrypted is arranged schematic diagram.A plurality of decryption cards (TF card) are housed on the present embodiment, and in the situation of available free decryption card, the program distribution decryption card of deciphering for needs is decrypted, thereby realizes the function that multiple programs is deciphered simultaneously.
Microprocessor comprises the initial stage module, and the state of all programs of initial stage module initialization for deciphering obtained current quantity and the initial stage of carrying out that decryption card has been installed; Comprise that the change deciphering arranges module, the change deciphering arranges the change that module is decrypted setting as required, the setting of the programs of needs deciphering is deciphering, the setting of the programs that does not need to decipher is non-decrypting, the user need can select deciphering and the program that does not need to decipher voluntarily, and arranging needs the number of programs of deciphering can not surpass current mounted decryption card quantity; Comprise the program decryption processing module, the program decryption processing module is carried out the program decryption set handling, and all program distribution decryption cards that need to be decrypted processing are decrypted, and as distributing decryption card, then is set to non-decrypting.
Referring to Fig. 3, a kind of device program decryption set handling flow chart that uses a plurality of decryption cards that a plurality of CMMB programs are decrypted.
Functional description: carry out the program decryption set handling, all program distribution decryption cards that need to be decrypted processing are decrypted, as distributing decryption card, then be set to non-decrypting.
When decryption card is set, decryption card and the program that needs deciphering are bound, and with the decryption card of correspondence be configured such that with in state.
When need deciphering program surpasses decryption card quantity, only have the program of processing first can bind decryption card and be decrypted operation, the program that exceeds decryption card quantity can be set to non-decrypting.
This flow process exists in program after obtaining the rendition list always, when deciphering setting can enter in the deciphering setting procedure after changing automatically.
Referring to Fig. 4, a kind of device change deciphering set handling flow chart that uses a plurality of decryption cards that a plurality of CMMB programs are decrypted.
Functional description: be decrypted as required the change of setting, the setting of the programs that needs are deciphered is deciphering, and the setting of the programs that does not need to decipher is non-decrypting.
When discharging the decryption card of program use, the decryption card binding that program is corresponding with it is removed, and its corresponding decryption card is set to untapped state.
When originally non-decrypting program change is set to decipher, in this flow process, only upgrades deciphering and be set to decrypted state, be not decrypted the card bindings; Finish in program decryption set handling flow process with the bindings of program card.
Can design as required usb hub in the present embodiment and can expand to 3,4, in addition 10 USB interface, corresponding TF card, the TF card reader can be designed as 2,3, even 9; Decryption card can make the TF card, also can be Micro SD card, or other are used for the storage card of CMMB condition reception.
Require emphasis in addition, all devices neither uniquely design by the USB interface expansion, SPI, and Ethernet interface, even I2C interface all are fine; As long as microprocessor, the CMMB tuner, card reader is supported this kind interface, the data that microprocessor is obtained tuner by this kind interface are dealt in the decryption card and are decrypted, the data flow after obtaining to decipher.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection range of the present utility model.
