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 VANC Processing 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 3.3 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 MUX-8258 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.
4. In the Line column, locate the line you wish to delete the VANC components for. Notice for interlaced formats
that the Line column on the left lists the lines in Field 1 , and the Line column on the right lists the lines in
Field 2 .
