Output MTP settings
To set the output skew:
1. Connect an oscilloscope (preferred) or a monitor (acceptable) to the VGA output of
the MTP/HDMI U R receiver.
2. Apply a crosshatch pattern to the input to be optimized.
3. Use the test equipment or examine the displayed video image with a critical eye to
determine which video signal (red, green, or blue) is most shifted to the left.
4. From the View menu in DSP Configurator, select Video I/O to open the Video I/O
workspace. Alternatively, press <F4>, or click Video I/O in the Legend section of
another workspace.
5. Double-click the MTP block on the output side. The Output MTP Settings dialog box
opens.
6. In the Skew section, click the Up and Down arrows or enter a value into the R, G, or B
field to adjust the skew setting of the leftmost video signal to the right until all three
colors are properly converged.
7. Click OK.
To set the output pre-peaking:
1. From the View menu in DSP Configurator, select Video I/O to open the Video I/O
workspace. Alternatively, you press <F4>, or click Video I/O in the Legend section
of another workspace.
2. Double-click the MTP block on the output side. The Output MTP Settings dialog box
opens.
3. Select the Pre-peak check box to enable pre-peaking. To disable pre-peaking, clear
the check box.
HDCP Compliance
Operation
The Audio & Video I/O workspace and the Video I/O workspace show an HDCP status
indicator section. HDCP status is derived from the digital input signal or digital output
signal.
The MLS 608 checks for output HDCP compliance only when the selected input source is
encrypted. When the source is encrypted, the firmware authenticates the output, checking
whether the sync is HDCP compliant or non-compliant.
When the selected input does not have a source connected or if the signal is not
encrypted, the output HDCP status is given as "unknown". Furthermore, when no source
is connected on the selected input, the TMDS lines on the Tx (output) are turned off, so
HDCP encryption status is lost for the output and all the inputs. Then the HDCP status is
given as unknown or unavailable.
When the MLS is currently on an active and encrypted digital input, the HDCP status
indicators in the software indicate the status on all digital inputs and output. If the input
is then switched to any analog input, the switcher mutes its digital output in favor of the
analog input. However, because only digital video is muted, the TMDS lines are not turned
off, and so the HDCP status indicators remain on.
