I know the function of the HDCP protocol, trying to figure out where the problem is, DVD can be normal to HDMI signal input to the display and TV, has been tested successfully, the video capture card can also be a normal collection to the camera HDMI; but the HDMI output signal of DVD but can not be video acquisition card collection want to understand, thank you!
All DVD Blu ray machines and other video source HDMI with digital rights protection all have HDCP, and the receiver must have authorized decryption chip to collect or display
Display manufacturers built-in HDMI chip, pay a patent fee, the camera's HDMI output is not HDCP protection, of course, no problem
The camera's HDMI output is not protected by HDCP, of course, no problem, all DVD Blu ray and other digital copyright protection of video source HDMI has HDCP, the receiver must have the authority to collect or display chip decryption
