It is hard to protect the video content, for example, I can record what is playing on my screen or TV by a video camera.

Recording by application that capture the screen can be prevented in many ways, such as encrypting the digital content in the graphics card, enforce the use of customized video player the control the screen capturing.

To enable the full protection of video content copy right, the new screens and TV might enable adding vision glare that only can be detected by video recording lenses to prevent even the low quality video recording and the violation of copywrites.

This feature should be implemented with enable/disable property that can be controlled by the video producer by adding a preamble bytes that enable this features for screens and TV. Similar to the preamble bytes that used by S/PDIF encoding.

This also, will enable the verification of preventing the redistribution of video contents that need a consent to watch such as violent video content of slaughter animals that might be distributed for a ranch house livestock to proof for its consumers that the animals were killed in a specific religious way (Halal and Kosher).
