Embodiment Construction

[0021] Through the analysis of the prior art, the inventor found that the above-mentioned TV program sharing technical solutions adopted in the prior art have a common defect, that is, when a terminal that does not have the function of receiving TV program data is assisted by a terminal with the function When watching TV programs, the former can only receive the TV program data received by the latter, and the former has no function of descrambling the scrambled TV program data.

[0022] In addition, after further analysis of the defects in the prior art, the inventor found that in the prior art, the mobile TV service (the mobile TV service is the service in which the operator provides the terminal with TV programs that the terminal can watch , the service is generally a charging service) Features: The mobile TV service is a service item provided by the operator, and its profitability is the basis of service promotion. Therefore, similar to ordinary digital TV services and cabl...

Abstract

The invention discloses a method and a device for processing television program data, which are used for solving the problem that in the prior art, when a terminal without a television program data reception function watches television programs with the help of a terminal with the television program data reception function, the former only receives the television program data received by the latter, and the former cannot descramble scrambled television program data. The method comprises the following steps: a first terminal realizes television program subscription through registering into a television program service server by using UAM so as to obtain MSK, and sends a request message of subscribed television programs to a second terminal with the television program reception function; the second terminal receives the scrambled television program data which are broadcasted by a television program source server and corresponding to the request information as well as MTK, and sends the scrambled television program data and MTK to the first terminal; and the first terminal decrypts the MTK by using the MSK so as to obtain a control word CK, and uses CK to descramble the scrambled television program data.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method and device for processing television program data. Background technique [0002] With the popularization of terminals and the improvement of terminal performance, the scope of users' use of terminals is no longer limited to voice calls, but also includes using terminals to surf the Internet and browse multimedia files. Recently, a more popular new function of the terminal is to use the terminal to receive and play broadcast TV programs. This function enables the terminal to have a flexible ability to receive multimedia files, so it has been welcomed by users as soon as it is launched. In the prior art, if a terminal is to be used to receive and play broadcasted TV programs, the terminal is required to be provided with a module for receiving broadcasted TV programs (this module is generally a "television program receiving chip", also called a multimedia broadca...
