Embodiment 1

[0040] Such as figure 1 As shown, the flow chart of an OTT TV external anti-screen recording method provided by the disclosed embodiment of the present invention, the method includes:

[0041] S11: Obtain image frame data collected by an external camera device;

[0042] S12: Determine whether there is an illegal recording behavior according to the image frame data;

[0043] S13: If yes, generate an illegal screen recording message event to stop receiving signals.

[0044] In specific practice, the judging whether there is an illegal recording behavior based on the image frame data includes:

[0045] Compressing and coding the image frame data, sending the compressed and coded image frame data to the remote service module, receiving the compressed and coded image frame data by the remote service module, and compressing and encoding the compressed and coded image Decompress the frame data, and use the image recognition algorithm and model matching algorithm to detect and matc...

Embodiment 2

[0054] Such as figure 2 As shown, the embodiment of the present invention also provides an OTT TV external anti-screen recording device, including:

[0055] Obtaining module 21, is used for obtaining the image frame data that external camera equipment gathers;

[0056] Judging module 22, for judging whether there is an illegal recording behavior according to the image frame data;

[0057] The generating module 23 is configured to generate an illegal screen recording message event to stop receiving signals when there is an illegal recording behavior.

[0058] In specific practice, the judging module 22 is configured to compress and encode the image frame data, send the compressed and encoded image frame data to the remote service module, and receive the compressed and encoded image frame data by the remote service module. Decompressing the compressed and encoded image frame data, using an image recognition algorithm and a model matching algorithm to detect and match the deco...

Embodiment 3

[0062] Such as image 3 As shown, the embodiment of the present invention also provides an OTT TV external anti-screen recording system, including:

[0063] TV signal receiving module, event monitoring module, scene perception module and cloud service module;

[0064] In the start-up stage of the set-top box, the scene perception module is used to perceive and detect whether an external camera device is normally connected, if no externally connected camera device is detected, a message event is triggered to the application layer, and the application layer is notified to prompt the user that no external connection is found camera device, when the user requests to play, the event monitoring module captures the user request, and judges that the state at this time is the camera device not connected state, rejects the user's request to play, and when the external camera device is not connected normally, the user You will not be able to watch the video normally;

[0065] After the...

Abstract

The invention discloses an OTT television external screen recording prevention method and device, and the method comprises the steps: obtaining image frame data collected by external camera equipment; judging whether an illegal recording behavior exists or not according to the image frame data; if yes, an illegal screen recording message event is generated to stop receiving the signal, and the problem that in the prior art, piracy cannot be eradicated due to the fact that a digital copyright protection technology is adopted to encrypt video content or a watermark mode is adopted to declarate copyright ownership or a video recording behavior on a system level is achieved through control of an application layer is solved.

Description

technical field [0001] The invention relates to the technical field of multimedia video protection, in particular to a method and device for preventing external screen recording of an OTT TV. Background technique [0002] With the rapid development of online video, copyright issues have become increasingly prominent, and rampant piracy has hindered the healthy development of the video industry. At present, the means to prevent video piracy are usually to use digital copyright protection technology to encrypt video content or to declare copyright ownership through watermarking, or to realize video recording behavior at the system level through application layer control. However, the above methods still cannot To solve the problem of piracy, the pirate can watch the video through the identity of the authorized person, use an external video recording device (such as a video recorder, etc.) to record the video, and then edit the recorded video to crack the digital copyright prot...
