This method makes it difficult for set-top box manufacturers to effectively manage the authorized software for a long time. For example, when the software expires or the authorization is revoked, if it is to be updated in time, it is necessary to control all the extended applications that have been released in the set-top box terminal. All changes are costly

A method for generating and obtaining authorized application list information includes that: authorized application list information is generated in a front server, then the authorized application list information is sent to a digital TV set reception terminal, the digital TV set reception terminal obtains the authorized application list information from the front server in a way of a bi-directional network or wireless data carousel scheme, verifies and updates an authorized application list in the digital TV set reception terminal, so that, when the digital TV set reception terminal is initiated, the digital TV set reception terminal can add the corresponding expanded software into an application team according to the authorized application list. Accordingly, the corresponding device and system are disclosed in the present invention, which realize effective management of expanded software, and ensure a safe operation of software of the digital TV set reception terminal.
Description
technical field [0001] The present invention relates to the technical field of digital television, in particular to a method for generating and acquiring authorized application list information, a corresponding device and a system. Background technique [0002] With the development of digital technology, the function of the set-top box is greatly expanded. In addition to the original function of watching programs, the application manager on the set-top box can also control the operation of the extended application on the storage medium of the mobile hard disk. [0003] At present, the industry lacks a unified standard management extension software. The operation, suspension, recovery and stop of the extension software are generally controlled by the application manager. The extension application in the set-top box can obtain the corresponding interface to run through the service registered by the application manager. However, since the application manager of the existing set...
