Similarly, if the rate is increased then more nulls are introduced between the messages. This applies
equally whether in Drop/Repeat mode, or doing frame rate conversion.
CEA-708 has a more complex packet structure which allows for a variable amount of data per packet,
but the overall principal still applies.

Miscellaneous
This menu contains miscellaneous parameters generally associated with setting up the configuration of
the whole unit rather than input or output parameters. Use the up and down arrows to scroll to the
required sub-menu and press the Select/Enter key to enter the sub-menu. The following sections list the
sub-menus.
4.13.1.
Select Test Pattern
When Test Pattern is selected as the input channel the required test pattern can be selected here. Test
Patterns can also be changed with the up/down keys directly when the root menu with the status
information is up.

Channel Logo Overlay
A channel logo can be overlaid on the video image. Logo location can be set to be in the top left, top

Input Channel Config
This menu allows configuration of the various input channels. Scroll to the Input Channel Config menu.
Press the Select/Enter key. Scroll to the Input you want to configure and press the Select/Enter key. The
following items are available for each channel.
Input Select Key
There are 4 select buttons on the front of the unit which can be associated with inputs; these are used
for quick selection of inputs.
Native Modes in EDID (HDMI only)
This is to allow the unit to be seen by a source to operate with a preferred video input mode. Some
sources output a de-interlaced SD signal automatically and they can be forced to output an interlaced
output.
Legacy Mode (HDMI only)
Puts the unit into HDMI 1.1 mode to support older sources which are unable to operate correctly on
seeing an HDMI 1.3 receiver. This can happen with some HDMI repeaters which copy EDID data from
the unit where that data exceeds the source equipment’s own HDMI capability.
Colour Space (DVI/HDMI only)
Some HDMI sources or repeaters may not output in the color space they report. Some DVI sources may
not output in the RGB colour space. Their output colour space can be forced with this setting.
Colour Range (DVI/HDMI only)
Some HDMI sources or repeaters may not output in the color range they report. Some DVI sources may
not output in the full colour range. Their output colour range can be forced with this setting.
Component Format (Component only)
For analogue Component Video inputs only, select whether the input source provides YPbPr, YPbPrS,
RGB or RGBS video. It is also possible to choose between 0.7v and 1.0v video levels on the component
inputs. Most sources provide 0.7v video, plus 0.3v sync, but some do provide 1.0v (excluding syncs).
