Embodiment 1

[0028] figure 1 The structure of the audio and video protection system provided by the first embodiment of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0029] Such as figure 1 As shown, the audio and video protection system includes a digital TV system front end 1 and an audio and video terminal 2 . In the present invention, the audio and video terminal may be a digital TV set-top box, a tablet computer or a mobile phone, etc., preferably a digital TV set-top box. The front-end 1 of the digital TV system and the audio-video terminal 2 are connected and communicated in a wireless or wired manner.

[0030] The digital TV system front-end refers to a digital TV front-end system, including a source part, a processing part, a transmission part and a management part. The information source part is mainly used to generate various TV programs and data information, and the sourc...

Embodiment 2

[0041] figure 2 The implementation flow of the audio and video protection method provided by the second embodiment of the present invention is shown, and the details are as follows:

[0042]In step S201, when recording a program, the audio-video terminal receives a transport stream sent by the front end of the digital television system, and the transport stream includes fingerprint information and a scrambled audio-video stream.

[0043] In this embodiment, the audio-video terminal receives the transport stream sent by the front end of the digital television system when recording a program, and the transport stream includes fingerprint information and scrambled audio-video streams. The audio and video terminal is a digital TV set-top box, a mobile phone or a tablet computer.

[0044] In step S202, the audio-video terminal analyzes the transport stream to obtain the audio-video stream and fingerprint information before scrambling, encrypts the audio-video stream and fingerpri...

Embodiment 3

[0049] image 3 The implementation flow of the audio and video protection method provided by the third embodiment of the present invention is shown, and the details are as follows:

[0050] In step S301, the front end of the digital television system generates fingerprint information, scrambles audio and video streams, multiplexes the scrambled audio and video streams and fingerprint information to obtain transport streams, and sends the transport streams to audio and video terminals.

[0051] In the embodiment of the present invention, the audio-video terminal is a digital TV set-top box, a mobile phone or a tablet computer; preferably a digital TV set-top box. The fingerprint information includes the position of the fingerprint display, the duration of the fingerprint display, the size of the fingerprint font and the color of the fingerprint font, but does not include the content of the fingerprint.

[0052] The fingerprint content is generated by the audio-video terminal, ...

Abstract

The invention belongs to the field of digital television, and in particular relates to an audio-video protection method and an audio-video terminal, comprising: when the audio-video terminal records a program, it receives a transmission stream sent by the front end of a digital television system, and the transmission stream contains fingerprint information and scrambled Audio and video stream; analyze the transport stream to obtain the audio and video stream and fingerprint information before scrambling, encrypt the audio and video stream and fingerprint information, and store the encrypted audio and video stream and fingerprint information in a designated storage equipment; when the audio and video terminal plays the recorded program, read the encrypted audio and video stream and fingerprint information from the specified storage device, and decrypt the encrypted and saved audio and video stream and fingerprint information to obtain the audio video stream and fingerprint information, play the audio and video stream and display the fingerprint content. The invention can protect the audio and video streams recorded in the audio and video terminals from malicious copying or recording.

Description

technical field [0001] The invention belongs to the field of digital television, in particular to an audio and video protection method and an audio and video terminal. Background technique [0002] Digital TV refers to the type of TV that uses digital TV signals in all links from the studio to transmission, transmission, and reception, or that all signal transmissions to the system are transmitted through digital streams composed of 1 and 0 digital strings. With the acceleration of the digitization process of the TV industry, more and more digital multimedia content is transmitted through digital signals, which not only improves the transmission efficiency, but also brings users a more high-definition experience. [0003] In the digital TV system, the encryption protection technology for audio and video streams in the front end and video transmission process has been very mature. However, at the terminal, the audio and video stream obtained after the authorized set-top box ...
