Abstract
A kind of user authorization method which is used in digital TV set top box pickaback plane and master adds top box master infrared sending module, remote control infrared receiving module. Unique authorization key which is relative with master is between the top box master and pickaback plane, the key is in master, the pickaback plane needs key for normal work. The master secrets key encryption and then transfers to the remote controller, the remote controller transfers the information encrypted to the pickaback plane, the pickaback plane deciphers and obtains key for work. The remote controller accomplishes transmission of once information, and eliminates current authorization information stored in inner memory. The method can stop possibility that user uses digital TV set top box pickaback plane, it possesses characters that realization is easy, production cost is low, safety is high, usage is convenient.
Description
Affiliated technical field
The present invention relates to a kind of authorization method that is used between digital TV STB slave-master device, especially can effectively stop the method that the user illegally uses the digital TV set-top box handset.
Background technology
At present, digital TV set-top box adopts a machine one box in the use usually, independent charge.For the family that multiple TV set is arranged, for looking after user ' s right, existing way is that first set-top box fully charged, and the license fee of all the other set-top box is successively decreased by platform.
Owing in set-top box, lack effective user authorization mechanism at present, after occurring the user easily and purchasing many set-top box, give other people to use in the handset mode, the license fee usefulness that covert escape should be paid has greatly been damaged the rights and interests of operator and other validated user.
In simulated television Fare Collection System in the past, there is the method for carrying out subscriber authorisation by the radio signal of using the FSK modulation, but the hardware cost of this method higher (more than 35 yuan), and have problems such as external interference and electromagnetic pollution.
Summary of the invention
In order to solve the problem that lacks subscriber entitlement method between the existing digital TV STB slave-master device, the present invention proposes a kind of authorization method by remote controller transmission authorization message, can address this problem under extremely low hardware cost.
The technical solution adopted for the present invention to solve the technical problems is: at hardware aspect, machine tool increases an infrared signal radiating portion, and remote controller increases an infrared signal receiving unit; Aspect software, there is unique authorization key between machine tool and the handset, this key is present among the machine tool, handset need be obtained this key ability operate as normal, machine tool sends remote controller to after with secret key encryption during use, information after remote controller will be encrypted sends handset to, obtains key after the handset deciphering and begins operate as normal.
The invention has the beneficial effects as follows that this subscriber entitlement method can be realized the mandate binding between handset and the machine tool with very cheap hardware cost (being approximately 3 yuans), guarantees the rights and interests of digital-TV operator and validated user.
Description of drawings
Fig. 1 is a functional-block diagram of the present invention.
Fig. 2 is a circuit connection diagram of the present invention.
Fig. 3 is a software flow pattern of the present invention.
Embodiment
In Fig. 1, (1) is the infrared receiving module of set-top box machine tool, (2) be the CPU of set-top box machine tool, (3) be the infrared sending module of set-top box machine tool, (4) be the infrared receiving module of remote controller, (5) are the infrared receiving modules of set-top box handset, and (6) are the CPU of set-top box handset, (7) be the CPU of remote controller, (8) are the infrared sending modules of remote controller.Wherein, the infrared sending module (3) of set-top box machine tool and the infrared receiving module (4) of remote controller are the hardware components that increases on the basis of original television set and set-top box, and cost is approximately 3 yuans.
In Fig. 2, D1 is the infrarede emitting diode of the infrared sending module of set-top box machine tool, and D2 is the infrared photodiode of the infrared receiving module of remote controller, and R1, R2 are current-limiting resistances, and T1 is the switching tube of the infrared sending module of set-top box machine tool.
In Fig. 3, during system works, the user at first uses a teleswitch and sends the instruction of request authorization code to the set-top box machine tool, after the set-top box machine tool is received instruction, with the business cipher key in the current digital television code stream authorization code is encrypted, authorization code after will encrypting then is (unique corresponding with the set-top box machine tool, and bind legal mandate set-top box handset) send to remote controller, authorization code after remote controller will be encrypted again passes to the set-top box handset, after handset is received this information, with the business cipher key in the current digital television code stream to the authorized sign indicating number of its deciphering, if authorization code effectively then begin video output.After remote controller is finished the transmission of an authorization message, remove the current authorization message of storage inside automatically.
Claims (2)
1, a kind of method of authorization of digital TV STB slave-master device, increase the infrared sending module of set-top box machine tool, remote controller infrared receiving module, it is characterized in that: have the unique authorization key relevant between set-top box machine tool and the handset with machine tool, this key is present among the machine tool, and handset need be obtained this key can operate as normal; Machine tool sends remote controller to after with secret key encryption, and the information after remote controller will be encrypted sends handset to, obtains key after the handset deciphering and could begin operate as normal.
2, a kind of authorization of digital TV STB slave-master device method according to claim 1 is characterized in that: after remote controller is finished the transmission of an authorization message, remove the current authorization message of storage inside automatically.
