Control Descriptions
Output Format
The output format can be selected from 1080i,
720p or SD. Although it is possible to select the
output to be the same as the input format, apart
from 1080p, setting the output to a higher
format than the input will be flagged as
incompatible and the output will be replaced
with black, blue or muted as selected in the
output incompatibility mode menu. The position
of the on-board links PL2, PL3 and PL4 must be set
to give either an SDI output or analogue output as
required.
Analog Output
Format
As the Q-Down 3G range supports both
Standard Definition and High Definition
analogue output formats, the final analogue
output presented will be determined by both the
analogue output format selection and digital
output format selection. Setting the output
format to SD will allow the analogue output
format to be selected from any of the available
choices. If one of the High Definition output
formats were to be selected, the analogue
outputs would be limited to either HD YUV or
RGB. The analogue video line rate will be the
same as that of the input video. The position of
the on-board links PL2, PL3 and PL4 must be set to
give either an SDI output or analogue output as
required.
NTSC Levels
Set the luminance, chrominance and sync
levels to the correct values for either
SMPTE/EBU N10 or Betacam standards.
Pedestal
Set black level offset for NTSC standard.
Vertical
Bandwidth
When down converting, the vertical bandwidth
can be optimised for a given application by
selecting the most appropriate vertical
bandwidth filtering. There are four filters to
select from, ranging from the highest (sharpest)
to the lowest (softest).
Select
Should the video input format and output
format selection become incompatible, for
example in the situation where the input is a
lower bit rate than the output selection, the
output can be set to go to black, blue or muted
to no output.
