Every 16 video frames: Reads PJ from the serializer and PJ’
from the deserializer.
If PJ matches PJ’, the enhanced link integrity check is suc-
cessful, go back to step 3.
If there is a mismatch, retry up to two more times from step
3. Enhanced link integrity check fails after three mismatch-
es. After the detection of failure of enhanced link integrity
check, the FC ensures that the A/V data not requiring
protection (low-value content) is available at the serializer
inputs (such as blue or informative screen). Alternatively,
the FORCE_VIDEO and FORCE_AUDIO bits of the serializer
can be used to mask the A/V data input of the serializer.
Writes 0 to the ENCRYPTION_ENABLE bit of the serializer
and the deserializer.
Restarts authentication by writing 1 to the RESET_HDCP bit
followed by writing 1 to the START_AUTHENTICATION bit in
the serializer.
If RI does not match RI’, link integrity check fails. After
the detection of failure of link integrity check, the FC
ensures that A/V data not requiring protection (low-value
content) is available at the serializer inputs (such as blue
or informative screen). Alternatively, the FORCE_VIDEO
and FORCE_AUDIO bits of the serializer can be used to
mask the A/V data input of the serializer.
Writes 0 to the ENCRYPTION_ENABLE bit of the
serializer and deserializer.
Restarts authentication by writing 1 to the
RESET_HDCP bit followed by writing 1 to the
START_AUTHENTICATION bit in the serializer.
