HDCP Restrictions On CORIO2 Units

HDCP is a copyright protection system (High bandwidth Digital Copy Protection). Therefore its primary aim is to prevent protected material (usually High Definition video) from being copied.

It does this by encrypting the video signal between the source (e.g. DVD player) and sink (e.g. display). To do this, each source and sink must be HDCP compatible and negotiate with each other to create a secure link. They do this by exchanging 'keys' and working out a secret encryption 'password'.

Units that support HDCP in the CORIO2 range are required by the HDCP license to ensure that encrypted data from a source stays encrypted on its outputs.

This requirement then forces an HDCP-compliant unit to shut-down any non-encrypted outputs such as analog RGB, SDI or composite video.

This is not a fault with the CORIO2 unit, but a requirement by the HDCP license granted to tvONE - and thus all HDCP compliant units should work in the same way.

The HDCP implementation is version 1.2, with full repeater support of up to 10 down-stream devices.

Summary: a HDCP-encrypted DVI/HDMI source entering a unit *must* leave by a HDCP-encrypted DVI/HDMI output. No other outputs are allowed to work under the terms of the HDCP license.
