Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described embodiment is only some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of the application protection.
Embodiment one
Refer to Fig. 1, it illustrates a kind of flow chart of the Conditional Access Module of the application offer and the adaptation method of carrier network, it is possible to comprise the following steps:
Step S11: Conditional Access Module selects customization function module to be used from carrier network.
In the present embodiment, customization function module to be used is be adapted to carrier network corresponding to conditions present receiver module and be adapted to the customization function module of conditions present receiver module, its concrete function provided corresponding to the carrier network operator that conditions present receiver module is corresponding.
Wherein, the form of customization function module to be used does not limit, it is possible to be software module, it is also possible to be configuration file.
In the present embodiment, owing to there is multiple different customization function module in same carrier network, therefore Conditional Access Module needs to select customization function module to be used from multiple customization function modules successively.
It should be noted that customization function module to be used corresponding to different carrier networks is different.
Conditional Access Module selects the customization function module to be used in carrier network successively, until Conditional Access Module has stored all of customization function module to be used in carrier network.
Step S12: described Conditional Access Module obtains and store described customization function module, so that described Conditional Access Module can run described customization function module to be used, is decrypted and experiences, to the digital television program of encryption, the various functions that operator provides.
In this application, owing to passing through to throw in the customization function module being adapted to this operator in the operator network, chosen in use by Conditional Access Module, download and store customization function module, it is no longer necessary to the Conditional Access Module integrated customization function module being adapted to each operator in advance, therefore Conditional Access Module manufacturer can produce the Conditional Access Module of not integrated customization function module in advance, each operator need not be respectively directed to and produce the Conditional Access Module of customization, thus being no longer necessary to management for the substantial amounts of customization function module of all operators, reduce production cost, improve production efficiency.
