Fast Link Verification
HDCP periodically verifies that the HDCP
Receiver is correctly synchronized. Setting this bit
will increase the rate at which synchronization is
verified. When set to a 1, Pj is computed every 2
frames and Ri is computed every 16 frames. When
set to a 0, Pj is computed every 16 frames and Ri
is computed every 128 frames.
