About the PDS

^=tçêÇ=^Äçìí=ea`m

The PDS supports High-Bandwidth Digital Content Protection (HDCP), an industry-wide content protection system designed to prevent illegal copying of digital audio and video content across interfaces such as DisplayPort (DP), High-Definition Multimedia Interface (HDMI), and Digital Visual Interface (DVI). HDCP prevents the display of encrypted content on devices that do not support content protection.

The HDCP format was designed by Intel® Corporation, and it uses an “authentication and key exchange” procedure to accomplish the required protection. For proper implementation, products that are compatible with the HDCP format require a secure connection to a compliant display, such as a projector or monitor.

When an HDCP-compliant display is connected to the PDS, an HDCP “session” is created. In this session (which is transparent to the user), “keys” are exchanged between the source device (e.g., a Blu-Ray player) and the HDCP-compliant display. The source device queries the display to ensure that the equipment is HDCP compliant before video is displayed.

Non-HDCP equipment such as a PC will work with any DVI-compliant display, but HDCP- compliant equipment shows protected content only on HDCP-compliant displays.

With the HDCP option enabled, the PDS accepts encrypted content from an external source, decrypts the signal for internal processing such as scaling or color balance, then re-encrypts the output video for display. During this process, all PDS output connectors that are not HDCP-compliant are turned off, when the protected content is selected to be shown on those outputs. In addition, if a non-HDCP compliant monitor is connected to the DVI Program output, Preview will show Black for an HDCP source regardless of the HDCP capability of the DVI monitor connected to the Preview output. This is to maintain the true "look-ahead" preview functionality of the PDS.

This feature is available on the PDS DVI input and output connections. Please note the following important points:

You can turn the HDCP option on or off. If the option is turned off and the signal is encrypted, the PDS does not send the signal to the output device.
