2 Chapter 1 Testing HDMI Devices
Encoding audio into HDMI stream
This section describes how to encode audio signals, for internal and external sources, into
the HDMI stream output from the generator.
Encoding internal audio into HDMI content stream
The HDMI generator can generate an audio stream sinewave signal, which is output with
the HDMI signal. The audio stream is IEC 60958-3 Consumer LPCM, with left and right
channels.
The digital audio stream uses 16 bits per sample. The ARAT command (page 6) can set the
sampling frequency at 32.0, 44.1, or 48 (default) KHz.
The audio stream is a sinewave with a frequency between 20 and 20,000 MHz, and an
amplitude between -96.3 and 0.0 dBFS. The SRAT command (page 22) controls the
frequency. The SAMP command (page 18) controls the amplitude.
To encode an internal audio source with the HDMI output:
1. Establish a command terminal connection with the generator, using HyperTerminal or
VGM.
2. At the R:> prompt, enter SDMG 1 to configure the generator to use internal audio,
rather than external audio.
3. Load one of these images to generate the audio signal:
4. To adjust the amplitude (in decibels, full scale), press the Step button, and then turn the
Image knob. The SAMP command can also be used to control the amplitude.
The amplitude setting is saved until you change it again.
Encoding external audio into HDMI content stream
Currently, the HDMI generator outputs only basic audio signals. However, it can encode
audio signals from an external source, such as a DVD player, with the HDMI content
stream. The audio stream type must be Linear PCM.
Audio_L Outputs left channel only.
Audio_R Outputs right channel only.
Audio_LR Outputs left and right channels.

802BT HDMI Video Test Generator Users Guide (Rev A) 3
To encode an external audio source with the HDMI output:
1. Use the RCA-to-VGA cable (provided with generator) to connect the external audio
source to the AV connector on the generator.
The AV interface is a modified VGA connector, which uses pins 6 and 11 for SP/DIF
input.
2. Establish a command terminal connection with the generator, using HyperTerminal or
VGM.
3. At the R:> prompt, enter SDMG 2 to configure the generator to accept an external audio
source.
4. (Optional) Use the ARAT command (page x) to set the sample frequency to match the
frequency of the source. The default frequency is 48 KHz, which is used by DVD
players.
5. Turn on the audio source.
Currently, the generator cannot independently control channels from external sources.
You must use the device generating the audio signal to control the channels.
6. Load any image and an appropriate video format.

6 Chapter 2 Testing HDCP-Compliant Devices
Testing DVI Tx with DVI Rx
Quantum Data 802 DVI generators use either a Broadcom DVI transmitter or a Silicon
Image DVI transmitter. The Broadcom transmitters support production and public
(A1/A2 and B1/B2) keys. Generators with a Silicon Image transmitter support only
production keys.
To identify the transmitter type in your generator:
1. Load the GenStats image.
2. Read the information under the Options heading.
If DVI (SiI) or DVI Analyzer (SiI169) is displayed under Options, the generator has a
Silicon Image transmitter. If DVI is displayed, the generator has a Broadcom
(BCM7500) transmitter.
To test HDCP:
1. Connect the DVI transmitter on the generator to the device’s DVI receiver.
2. Select an appropriate test image.
If you are testing a device with a production key, select the HdcpProd(uction) image.
The HdcpProd image assumes that both the HDCP transmitter and receiver have a
production key.
If you are using a Broadcom DVI transmitter to test a device with a public key, select
the appropriate image below. For example, if the receiver has pubic key B2, and you
want to use public key A1 in the transmitter, then select the HdcpA1B2 image.
• HdcpA1B1
• HdcpA1B2
• HdcpA2B1
• HdcpA2B2
The image will indicate if the test passed or failed. If the test fails, see “Troubleshooting
HDCP errors” on page 10.
3. To test another device, connect the cable to the new device.
The HDCP test starts automatically.

802BT HDMI Video Test Generator Users Guide (Rev A) 7
Testing HDMI Tx with HDMI Rx
All HDMI transmitters in Quantum Data generators support only production keys.
To test HDCP with HDMI devices:
1. Connect the HDMI transmitter on the generator to the device’s HDMI receiver.
2. Select the HdcpProd(uction) image.
The image will indicate if the test passed or failed. If the test fails, see “Troubleshooting
HDCP errors” on page 10.

8 Chapter 2 Testing HDCP-Compliant Devices
Testing HDMI Tx with DVI Rx
HDCP 1.1-compliant devices must interoperate with HDCP 1.0-compliant devices using
the DVI protocol. Generators with an HDMI transmitter can be used to test HDCP with
devices that have an DVI receiver.
To test HDMI Tx with DVI Rx:
1. Establish a command terminal connection with the generator, using HyperTerminal or
VGM.
2. At the R:> prompt, type HDMI 0; ALLU to set the HDMI transmitter into DVI mode,
which disables audio.
The DVI mode setting is saved until you change it.
3. Use an HDMI-to-DVI cable (provided with HDMI generator) to connect the HDMI
transmitter to the DVI receiver.
4. Load the HdcpProd image. This image assumes that both the transmitter and receiver
are using production keys.
The image will indicate if the test passed or failed. If the test fails, see “Troubleshooting
HDCP errors” on page 10.
To change HDMI transmitter from DVI to HDMI mode:
1. Establish a command terminal connection with the generator, using HyperTerminal or
VGM.
2. At the R:> prompt, type HDMI 1; ALLU

802BT HDMI Video Test Generator Users Guide (Rev A) 9
Testing HDCP with static images
The standard HDCP images have color bars in the background. A special mode is
available for testing HDCP with any static background image you specify.
To test HDCP with a different background image:
1. Turn on generator while holding down the G and ACS buttons until hdcp tester is
displayed.
2. Select a format that is supported by the display, and then load any static image.
The HDCP test begins automatically when you connect the display.
The generator displays the image you specified if the HDCP test passed. If the test
failed, the display will remain blank. See “Troubleshooting HDCP errors” on page 10.

10 Chapter 2 Testing HDCP-Compliant Devices
Troubleshooting HDCP errors
Common problems
This table describes possible solutions to problems that may occur during HDCP testing.
Running HDCP test in manual mode
The generator normally runs the steps in the HDCP test automatically. If the test fails, the
test is restarted after a few seconds, which makes it difficult to read values at the step
where the test failed. All HDCP tests have a manual mode, which you can use to pause the
test after each step.
To run the HDCP test in manual mode:
1. At any step during an HDCP test, press the Step button.
2. Turn the Image knob to advance to the next step. If you are using an PCI-based
generator, use the commands displayed on the screen to advance to the next step.
3. Press the Step button again to return to automatic mode.
Understanding the HDCP test
Understanding what the generator does during an HDCP test can help you determine
why an HDCP test failed.
Test sequence for Broadcom transmitters:
1. The generator resets the transmitter and its HDCP engine.
Problem Solution
Test fails at step 3 Transmitter could not read Bksv from the receiver,
Bksv was read correctly but is a wrong value, or an
I2C error occurred.
If the EdidData image loads, the I2C communication
is working properly.
Verify that the Bksv value is 5 bytes (that is, 40 bits of
which 20 zeros and 20 ones) by reading the value from
the test image.
HdcpProd image flashes repeat-
edly at step 9
Restart the generator while holding down the Out-
puts button, which starts the generator in “Reset
HDCP Rx by gating clock” mode.

802BT HDMI Video Test Generator Users Guide (Rev A) 11
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.
