Multi-condition reception supporting system and method used for set up box

Abstract

The invention discloses a system and a method for multi-condition receiving and support on the set-top box; the method is used in the set-top box system formed by an interlayer, a software development kit module and a portable application programming interface module. The interlayer comprises a video and audio control object, a service information engine object and a condition receiving object interface. The method comprises two concurrent processes of a background processing of the authorization management information and a radio station processing. The multi-condition receiving and support system used in the set-top box of the invention comprises an interlayer and a portable application programming interface module, and the interlayer further comprises: a video and audio control object and a condition receiving object interface, and a service information engine object used to acquire the related control information of the condition receiving according to analyzing the service information form; the portable application programming interface module can be used to support the broadcasting of the video and audio, the receiving of the service information and the condition receiving data, the transmission of the smart card data, the usage of the descrambling device and the invoke of the operating system.

Description

technical field [0001] The invention relates to a multi-conditional reception support technology, in particular to a system and method for a multi-conditional reception support used on a set-top box. Background technique [0002] With the acceleration of the national cable TV digitization process, set-top boxes are becoming a hot product, but set-top boxes cannot be sold in shopping malls as ordinary commodities. Because set-top boxes are customized for specific operators, each set-top box must obtain an order from the operator before production. The operator specifies a series of technical requirements, especially software and applications, and then can be produced according to the order. In this way, the current manufacturers cannot produce large-scale products like ordinary home appliances, and then directly promote them through their own sales channels. Domestic manufacturers hope to turn set-top boxes into general-purpose consumer products similar to color TVs, so that...

Problems solved by technology

In order to solve the openness problem of the set-top box, a technical solution of machine-card separation is proposed. At present, there are several schemes for realizing machine-card separation: 1) The scheme based on PCMCIA card. The disadvantage of this scheme is that the cost is high. The cost of the module is even higher than the cost of the whole machine

2) Plug-in-based small card solution The disadvantage of this solution is that it reduces the security of the original CA and increases the complexity and manufacturing cost of the IC card itself

It is quite complicated and inoperable to obtain the support of existing CA manufacturers
