PROBLEM – HDCP KEY OVERRUNS AUTOMATICALLY SHUTDOWN SOURCE DEVICE

HDMI/HDCP authentication requires sources to validate downstream display keys to ensure that all

destinations are HDCP compliant. However, there is no requirement specifying how many of those

device keys a source manufacturer must support. As a result, varying HDMI/HDCP sources support a

range of downstream keys. Even within a single manufacturer’s product line, key support numbers vary

and are rarely provided in product documentation. This unknown key support limit is generally only

discovered once it is exceeded and the source device simply shuts itself off.

NON-AMX SOLUTIONS - PREVENT USERS FROM WATCHING VIDEO EVERYWHERE THEY WANT

Overcoming key overruns has traditionally been dealt with via a set of tools or design considerations,

which limit the number of outputs a source can be switched to. Some sources support a single key,

which limits a matrix switcher to switch to only a single output at a time. When a user wants to switch to

more than one output or all outputs, this becomes an issue.

AMX SOLUTION – INSTAGATE PRO ELIMINATES HDCP KEY OVERRUNS

With InstaGate Pro, the entire HDCP negotiation process is handled within the matrix switching system.

Validation of each output is completed without concern for source key limitations. As long as a source

can handle a single key, it can be sent to any or all outputs as long as those displays are HDCP compliant.

This process is handled without additional tools or programming. Simply plug in compliant sources and

destinations and begin switching. In addition, because every output is being validated for HDCP

compliance individually, switching an HDCP source to a non-compliant display won’t negatively affect

compliant displays showing video from the same source. The non-compliant display simply receives a

visual indication (solid red screen) that it is not receiving video, while all compliant displays continue to

show video without issue.
