In HDCP mode, all downstream traffic from X20 will be encrypted using HDCP Cipher irrespective of the nature
of incoming video through upstream connections. The upstream devices may choose to encrypt or not to
encrypt the contents based on the type of video content, but as soon as a device is connected downstream to
X20, X20 starts the authentication process and only HDCP enabled displays or devices will function.
HDCP mode also restricts the X20 outputs to function only in single link mode even for the Odd numbered
outputs (In normal mode Odd-numbered DVI outputs in X20 function at Dual-link rates).
During HDCP Authentication and content transfer, devices use the I2C (DDC) channel in DVI connections. The
reliability of I2C communication, in certain cases may depend on the length and quality of the cable and can
impact the HDCP communication.
Another concern is regarding usage of DVI distribution amplifiers, routers or splitters which are used in between
the sources and X20. If these devices are unable to manage HDCP or pass-through the DDC communication with
reliability, HDCP connection may end up being broken and unusable.
The X20 is categorized as an HDCP repeater. The definition of a repeater (from Wikipedia) is as follows:
A repeater accepts content, decrypts it, then re-encrypts and retransmits the data. It may perform some signal processing,
such as up-converting video into a higher-resolution format, or splitting out the audio portion of the signal.
Note that after source content is decrypted in the X20, it may not be retransmitted / output in any unencrypted
signal. HDCP support is a system-wide switch in X20, and as a result there are no supported scenarios involving
simultaneous HDCP outputs and non-HDCP outputs in the same system.
Configuring HDCP Mode
Enabling / disabling HDCP mode for X20 can be performed from the frame configuration panel (‘Server’
->
‘Frame Configuration’) in Vista Advanced, and requires a ‘soft’ restart of the X20 frame. When enabled, only
DVI
outputs which have made a successful HDCP handshake with the downstream display device will be enabled. All
other output connectors will be disabled.
