Implementation method and device of encryption self-adaptation of various digital copyrights in set top box

Abstract

The invention discloses implementation method and device of the encryption self-adaptation of various digital copyrights in a set top box. The method comprises the following steps of: configuring a parameter for each digital copyright encryption system by the set top box; when the set top box is powered on, acquiring the parameter of a current digital copyright encryption system and transmitting the parameter to an initialization interface; initializing a corresponding digital copyright encryption system by the initialization interface according to the parameter; synchronously establishing a connection by a connecting interface with a corresponding digital copyright encryption system server so as to carry out authentication, acquire a decryption key and transmit the decryption key to a decryption interface; establishing a decryption connection by the decryption interface to carry out program decryption; and transmitting a decrypted program to the set top box for playing. The system and the implementation method greatly improve the compatibility of terminals, the resource utilization rate and the matching capacity between various service operation systems, reduce the workload for maintaining different DRM (data rights management) editions and improve the safety of the system.

Description

technical field [0001] The invention relates to the field of multimedia terminals, in particular to a method and a device for implementing self-adaptive encryption of various digital copyrights in a set-top box. Background technique [0002] With the development of technology, multimedia terminal products, such as smart phones, PDAs and IPTV (Internet Protocol Television: Internet TV) set-top boxes, will gradually enter thousands of households and become an indispensable part of people's lives. As a typical multimedia terminal equipment, the IP set-top box greatly meets the needs of users with its rich program sources, convenient operation mode, and powerful multimedia service functions. However, the IPTV set-top box is still in the initial stage of development and needs continuous perfection. [0003] If IPTV is to develop, it will inevitably face the problem of piracy. Video and audio files are easily intercepted by others when they are transmitted over the network. This ...

AI Technical Summary

Problems solved by technology

[0005] At present, there are many excellent brands in the field of DRM encryption in the world, and they all have a good market share, but the encryption methods are not compatible

Therefore, in the process of IPTV international development, in order to meet the different needs of operators when using encryption systems, their terminals need to take into account multiple encryption methods when integrating DRM, but a new version is required for each DRM type. This will undoubtedly bring a lot of trouble to version maintenance, will greatly increase the workload, reduce the compatibility of the terminal, and also increase the burden on the operator, wasting a lot of resources of the operator
