A KSV is commonly called an HDCP ‘key’. A unique <br />ID for each HDMI sink that must be sent to HDCP-enabled sources <br />in order for the sinks to receive content. <br />3)The AV switching system shall not send a source more KSVs than it <br />supports. <br />4)The AV switching system shall cache the KSVs from each connected <br />sink. <br />5)The AV switching system shall authenticate all cached KSVs with <br />each source up to the source’s KSV limit, so that authentication does <br />not need to be re-started each time content is routed to a new <br />output. <br />g.Signal Detection
