Abstract

The embodiment of the invention provides a CAM card automatic identification method and identification device, and display equipment. After a CAM card is inserted into the display device, the type of the CAM card is determined according to a content control system identifier. Then the corresponding first verification data is sent to the CAM card according to the type of the CAM card to generate a first key. And meanwhile, the display equipment receives second verification data sent by the CAM card, generates a second secret key and sends the second secret key to the CAM card. And after the secret key exchange process is completed, the CAM card judges whether the first secret key and the second secret key are the same or not, and if the first secret key and the second secret key are the same, the CAM card is determined to be successfully authenticated. According to the embodiment of the invention, after different types of CAM cards are identified according to different content control system identifiers, a corresponding key exchange process is carried out according to the types of the CAM cards, so that the authentication of the CAM cards is completed. Therefore, no matter which type of CAM card is inserted by a user, automatic identification can be carried out, finally, media assets of any type of CAM card can be played, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of display equipment, in particular to a CAM card automatic identification method, identification device and display equipment. Background technique [0002] CAM (Conditional Access Module), also known as conditional access card, CAM card, its main function is to control the user's authority to watch authorized digital TV programs. In the smart TV system, the CAM card allows digital TV operators to control and manage authorization for users, thereby realizing paid services for digital TV programs. [0003] At present, there are mainly two types of CAM cards on the market, one is a standard CAM card, and the other is an ECP CAM (Enhanced Content Protection Conditional Access Module) card. According to the iteration of technology, the standard CAM card will be gradually replaced by the ECP CAM card, and the standard CAM card will also become a transitional product. [0004] However, in the product ...
