Embodiment Construction

[0020] In order to assist a terminal that does not have the function of receiving broadcast TV programs to watch TV programs, the inventor considers using a device with functions of UAM and broadcast TV program reception to assist the terminal to watch TV programs. The device integrates the UAM and multimedia broadcasting receiving module that the terminal does not have, and the terminal only needs to establish a connection with the device, and the device can realize functions such as receiving and descrambling scrambled TV program data.

[0021] Specifically, based on the above-mentioned device, an embodiment of the present invention firstly provides a method for processing TV program data. The specific flowchart of the method is shown in figure 2 shown, including the following steps:

[0022] Step 21, the TV program data processing device (hereinafter referred to as the processing device) receives the TV program data request message carrying the terminal identification sent...

Abstract

The invention discloses a method, a device and a system for processing television program data, which are used for assisting a terminal which does not have a function of receiving a broadcast television program in playing a television program. The method comprises the following steps that: the device for processing the television program data receives a television program data request message which is sent by the terminal and carried with a terminal identifier, and selects a user authentication module (UAM) matched with the terminal identifier from UAMs in the device; the device determines a television program service key (MSK) acquired by the selected UAM; the device receives scrambled television program data and a program steam key (MTK) which are broadcast by a television program source server through a multimedia broadcast receiving module arranged in the device; and the device decrypts the MTK by using the MSK to acquire a control character (CK), descrambles the scrambled television program data by using the CK and sends the descrambled television program data to a television program data receiving terminal so as to play the television program data.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method, device and system 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, the new function of the more popular terminal is to use the terminal to order and enjoy mobile TV services, that is, to receive and play broadcast TV programs. This function enables the terminal to have a flexible ability to receive multimedia files. Welcome. [0003] A schematic diagram of a terminal receiving broadcasted TV programs through the mobile TV service is as follows: figure 1 As shown, the terminal needs to obtain the user key (MUK) and the encrypted service key (MSK) from the mobile communication network, and the...
