HDCP GMSL SERIALIZER

HDCP GMSL DESERIALIZER

—

Generates Ri and updates the

RI register every 128 VSYNC

cycles.

Generates Ri’ and updates the RI’

—

Continues to encrypt and

transmit A/V data.

Continues to receive, decrypt, and

output A/V data.

Every 128 video frames (VSYNC cycles) or

every 2s.

—

Reads RI from the GMSL serializer.

—

Reads RI’ from the deserializer.

—

Reads RI again from the GMSL serializer and

makes sure it is stable (matches the previous

RI that it has read from the GMSL serializer). If

RI is not stable, go back to step 5.

—

If RI matches RI’, the link integrity check is

successful; go back to step 3.

—

If RI does not match RI’, the link integrity

check fails. After the detection of failure of

link integrity check, the FC makes sure that

A/V data not requiring protection (low-value

content) is available at the GMSL serializer

inputs (such as blue or informative screen).

Alternatively, the FORCE_VIDEO and

FORCE_AUDIO bits of the GMSL serializer

can be used to mask A/V data input of the

GMSL serializer.

—

Writes 0 to the ENCRYPTION_ENABLE bit of

the GMSL serializer and deserializer.

Disables encryption and

transmits low-value content A/V

data.

Disables decryption and outputs low-

value content A/V data.

Restarts authentication by writing 1 to the

RESET_HDCP bit followed by writing 1 to the

START_AUTHENTICATION bit in the GMSL

serializer.
