Embedding Non-PCM Signals
You can configure the card to embed non-PCM signals, such as Dolby® Digital and Dolby® E,
using the options available in DashBoard.
To configure the card to embed non-PCM signals
1. Launch DashBoard on your computer.
2. Display the Device View for the card you wish to configure.
3. Select the AES Inputs tab for the input channel you wish to configure.
4. Set the Sample Rate Conversion to Off.
5. Clear the Sum box to disable channel summing.
6. Set the Channel Gain to 0.
7. Clear the applicable Ch Invert check box to disable inverting on the channel.
HANC Processing
SMPTE 291M formatted ancillary packets, such as SMPTE 12M-2 (timecode), that are found in
the Luma portion (Y stream) of the HANC in an HD video signal (other than audio related
packets) will be passed from input to output.
VANC Processing
The VANC Processing tab in DashBoard provides options for replacing the full active portion of
selected lines of video with black. The tab is divided into separate sub-tabs for each format
(1080p, 1080i, 720p, 576i, and 480i) to provide selection of the lines. This enables you to
individually select any combination of lines, from line 1 up to the third line after the VI for the
current video format. For interlaced formats, the lines in the two fields are separately configured.
Table 3.4 lists the allowable line selections based on format.
To delete the VANC components in a line:
1. Display the Device View in DashBoard for the card you wish to configure.
2. Select the VANC Processing tab.
3. Select the sub-tab, located at the bottom of the VANC Processing tab, for the applicable
video format.
Note — When embedding the non-PCM signal, the A and B channels of the input
signal must be embedded on Channels 1 and 2, or Channels 3 and 4 of a given
group. For example, you would embed AES1A in G1Ch1, and AES1B in G1Ch2.
