The TL-C-HDCP converts an HDMI signal supporting HDCP 2.2 to HDCP 1.4. The HDMI input supports HDCP 2.2 and the HDMI output supports HDCP 1.4. The unit supports a 4K at 60Hz signal up to 15m, and transparently passes EDID signals. HDCP 2.2 is latest evolution of content protection. In other words, it’s the magic part of the HDMI signal that keeps people from copying DVDs, BluRays, streaming video, and other protected content. The good news is this allows Hollywood to capitalize on all their hard earned work. The bad news is you are going to have to purchase your own copy of Dances with Wolves. The even worse news is there are several versions of HDCP, and not all versions are compatible with each other.
