Function Description
TX AN7 TX_AN7: Value of byte 7 of the Serializer AN
Value
Reserved
Repeater
Indicates if the attached Receiver supports
downstream connections. This bit is valid once the
Bksv is ready as indicated by the BKSV_RDY bit
in the HDCP
KSV FIFO KSV FIFO Ready
Indicates the receiver has built the list of attached
KSVs and computed the verification value
Reserved
Features
HDCP v1.1_Features
The HDCP Receiver supports the Enhanced
Encryption Status Signaling (EESS), Advance
Cipher, and Enhanced Link Verification options.
Fast Re-
auth
The HDCP Receiver is capable of receiving
(unencrypted) video signal during the session re-
authentication.
Max
Devices
Maximum Devices Exceeded: Indicates a
topology error was detected. Indicates the number
of downstream devices has exceeded the depth of
the Repeater's KSV FIFO
Device
Count
Total number of attached downstream device. For
a Repeater, this will indicate the number of
downstream devices, not including the Repeater.
For an HDCP Receiver that is not also a Repeater,
this field will be 0
Reserved
Max
Cascade
Maximum Cascade Exceeded: Indicates a
topology error was detected — more than seven
levels of repeaters have been cascaded together
Cascade Indicates the number of attached levels of devices
Depth
for the Repeater
KSV FIFO KSV FIFO
Each read of the KSV FIFO returns one byte of the
KSV FIFO list composed by the downstream
Receiver.
