2. If the "Reset HDCP Rx by gating clock" mode is enabled, the generator resets the
receiver, and gates off transmitter clock and data. Otherwise, the receiver is not reset.
3. The transmitter reads the Bksv (HDCP receiver KSV), over the I2C bus, and verifies
that it has 20 zeros and 20 ones.
This step is the first interaction between the transmitter and receiver.
4. The receiver writes the receiver KSV to the transmitter.
5. The transmitter generates An (session random number).
6. The transmitter writes An to the receiver, using the I2C bus.
7. The transmitter writes the transmitter KSV to the receiver, using the I2C bus.
8. Load the transmitter keys.
9. The transmitter reads the Ri value (link verification response) from the receiver chip
and compares it with its own generated Ri value. They should match to proceed. If this
step fails, the test returns to step 1.
10. Generate authentication.
11. Transmitting encrypted data.
Test sequence for Silicon Image transmitters:
1. Reset the transmitter.
2. If the "Reset HDCP Rx by gating clock" mode is enabled, the generator initialize the
transmitter. Otherwise, do not initialize the transmitter.
3. At transmitter generate An.
4. Write An to the receiver, using the I2C bus.
This step is the first interaction between the transmitter and receiver. The transmitter
reads the Bksv, over the I2C bus, and verifies that it has 20 zeros and 20 ones.
5. Write the transmitter KSV to the receiver.
6. Read and verify the receiver KSV.
7. Write receiver KSV to transmitter.
8. Ri ready at transmitter.
9. The transmitter reads the Ri value from the receiver chip and compares it with its own
generated Ri value. They should match to proceed. If this step fails, the test returns to
step 1.
10. Generate authentication.
11. Transmitting encrypted data.
