Before audio frequency and video are broadcasted, embed server by audio frequency and video in audio frequency and video, embed corresponding watermark information, obtain broadcast message;
Described broadcast message is broadcasted by satellite or transmitting station;
Receiving terminal reads the watermark information in the broadcast message received, and is uploaded to cloud server after the mark of described receiving terminal and the described watermark information read are generated Detection Information;
Whether what described cloud server judged corresponding broadcast message according to described Detection Information belongs to safe broadcast, and generates examining report.
Further, according to described Detection Information, described cloud server judges whether corresponding broadcast message belongs to safe broadcast, and generates examining report and comprise:
When the watermark information in described Detection Information is complete, then judge that described broadcast message has legitimacy;
When the watermark information in described Detection Information is imperfect, then judge that described broadcast message does not have legitimacy, generate the examining report that this broadcast message does not belong to safe broadcast.
Further, according to described Detection Information, described cloud server judges whether corresponding broadcast message belongs to safe broadcast, and generates examining report and also comprise:
When described broadcast message has legitimacy, judge that whether the watermark information in described Detection Information is consistent with the watermark information of embedding further, if consistent, then generate the examining report that this broadcast message belongs to safe broadcast, if inconsistent, then generate the examining report that this broadcast message does not belong to safe broadcast.
Further, the watermark information in described Detection Information is imperfect to be comprised no-watermark information or has part watermark information.
Further, the watermark information that described audio frequency and video embedding server embeds comprises program source mark.
Further, the mark of described receiving terminal comprises MAC Address.
Further, the method also comprises:
Described audio frequency and video embed server and carry out scrambling to described broadcast message;
According to the watermark information embedded in described Detection Information and described broadcast message, described cloud server judges whether described receiving terminal belongs to the terminal of the described broadcast message of licensed broadcasting;
When described receiving terminal belongs to the terminal of the described broadcast message of licensed broadcasting, scrambler sends to described receiving terminal to be used for described broadcast message descrambling by described cloud server.
The beneficial effect that the present invention brings is as follows:
To broadcast message, whether safe broadcast detects cloud server, simultaneously, the mark of receiving terminal is included in Detection Information, when occurring the situation of the non-safe broadcast of broadcast message, cloud server can record the receiving terminal occurring safe broadcast hidden danger, thus the reason be convenient to right-safeguarding and searched problem, ensure the safe broadcast of audio frequency and video, legitimacy and the integrality of broadcast TV program can be guaranteed comprehensively, fast and accurately, prevent from intercutting, mistake broadcasts or the appearance of the situation such as signal rogue attacks.Further, the program audio video adding watermark can be used for resisting the attack such as coding, overlapping text, station symbol, A/D and/or D/A in broadcast television transmissions process.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of specification, and can become apparent, below especially exemplified by the specific embodiment of the present invention to allow above and other objects of the present invention, feature and advantage.
