Copyright protection has been around since the era of VHS. Anyone who’s attempted to copy a Blockbuster movie rental can tell you. Back then, it was dubbed Macro vision, which resulted to CSS for DVD and finally HDCP for DVD players, Blu-ray and HDTV devices similar to cable boxes & satellite. What is HDCP? HDCP stands for High-Bandwidth Digital Content Protection. It is a copy protection system to reduce the possibility of intercepting digital data midstream within the source to the display. HDCP is a design by Intel Corporation that requires the use of HDCP-certified products to receive an HDCP-encrypted digital signal. How it works is by encrypting a digital signal with a key that requires authentication from the transmitting and receiving device.The Digital Content Protection LLC organization that licenses HDCP describes the scope of HDCP as preserving digital entertainment content across the HDMI & DVI interface.
HDCP versions 2.2, 2.1 and 2.0 in detail:
HDCP 2.0 was issued in October 2008. New additions to version 2.0 include wireless capacity and locality checks. Many products in the current market will have an early HDCP version, which is fine because HDCP is compatible across versions.
HDCP 2.1 applies to specifically, the variant of HDCP mapping described by Revision 2.10 of this spec along with its associated errata, if applicable.
HDCP 2.2 is the newest evolution of copy protection. It’s intended to create a secure connection between a source and display. Supposedly, this is so you can’t use the output from a source (a DVD player, say) & plug it into some brand of recorder, to make a copy of the content. DRM, the encryption of the content itself, is another issue. HDCP doesn’t mind what goes across the cable, as long as that cable is protected.
It does this by generating encrypted keys between the source and the display(sink). Enabled repeaters similar to receivers, can be in the string also. The source and the sink need to be in balance, understanding their keys or no content gets transferred. If you’ve ever installed gear and get a blank screen (or turned on equipment in the wrong order and get a blank screen), the HDCP “handshake” is normally the issue.
4K HDCP 2.2 compliant HDMI Matrix Switchers utilizing HDBaseT™ are designed for 4K/UHD @ 60Hz video signals with POE, which stands for Power over Ethernet for receivers and analog audio breakout. Many matrix switchers provide flexible HDBaseT routing with both extended distance of 100 meters or long distance at 230 feet.
4K/UHD HDMI Extenders utilizing HDCP 2.2 transmit HDMI 4K signals up to 100 meters over s single category cable with Ethernet pass-through, IR/RS232 control, plus Power over Ethernet. They are compatible with signals up to 4K/UHD @ 60Hz with set multi-channel audio and remote for 12V, 24V & 48V power for the supporting receiver.
