[0045] In the first embodiment, the method and steps of the present invention for identifying digital television broadcast signals are as follows:

[0046] (1) At the front end of the digital TV broadcast signal transmission, use the digital TV program content to generate the identification code of the broadcast TV signal;

[0047] (2) At the front end of the digital TV broadcast signal transmission, the ID code of the broadcast TV signal is placed in a custom data stream conforming to the digital TV stream standard, and multiplexed with the original digital TV transport stream;

[0048] (3) At the digital TV broadcast signal transmission receiving end, by extracting and detecting the digital TV signal identification code, and combining its corresponding program content, the legality, validity and integrity of the received content are judged.

[0049] In the above step (1), the process of generating the broadcast and television signal identification code is:

Abstract

The invention discloses a method of personal identification of digital TV broadcasting signal, which applies part or all of program content, time information and channel identification information of digital TV to generate personal identification code of a broadcasting TV signal on a transmission front end of the digital TV broadcasting signal, then the personal identification code of the broadcasting TV signal is placed in a self-defined data code flow which meets the standard of digital TV code flow and the self-defined data code flow reuses the transmission together with the former digital TV transmission flow; the illegal signal can be identified effectively through judging the legitimacy, effectiveness and integrity of the received content by selecting and detecting the personal identification code of the digital TV signal on a transmission receiving end of the digital TV broadcasting signal. Each part of information of personal identification code provided by the invention has a uniformed simple block structure, and the receiving end can carry out the analysis conveniently. The invention can reasonably choose the corresponding signature information to generate the personal identification code according to different safety protection requirements, thus realizing the higher performance cost ratio on the premise of guaranteeing the system requirements.

Description

Technical field [0001] The invention belongs to the technical field of digital television broadcasting, and specifically relates to a method for identifying digital television broadcasting signals. Background technique [0002] my country's current radio and television transmission system is basically one-way broadcasting, mainly to ensure the normal transmission of radio and television programs, and does not have the ability to detect and distinguish illegal signals. my country’s current radio and television transmission mainly uses public communication satellites. According to ITU regulations, the main parameters of satellite transponders must be disclosed. Technically, any satellite signal transmission facility with certain conditions may enter the current satellite channel interference. In normal broadcast and television signal transmission, the satellite itself cannot determine whether the transmission is an illegal signal. At the same time, because the satellite channel is ...
