NAD T 765 - Manual (Page 19)

ABOUT VIDEO FORMATS
For many years, there was only one type of video format used. Composite video signals include the
Luminance (black & White) and Chroma (color) signals combined on one wire. S-Video uses separate
wires in a single cable for Luminance and Chroma signals. Component Video goes a step further
with separate cables for Luminance and the two elements of Chroma. For NTSC (America, japan)
as well as PAL signals(Europe, Asia) these are labeled Y, Cr, Cb. Television studios use the Component
Video format to keep these signals separate in order to maintain the best quality. As consumer video
equipment has improved this higher quality format has been included.
VIDEO FORMAT CONVERSION
The T 765 is equipped with a Video Format Converter. This allows for a simplified video
connectionbetween the T 765 and your TV Monitor when using multiple video formats such as
Composite (CVBS), S-Video, and Component (YUV). This format change is accomplished by encoding
the analog video signal intoa digital signal using a very high quality digital encoder to maintain the
best possible picture quality. Once in a digital format, it can be decoded into any of the three standard
analog video formats.
It is suggested that you select the highest quality video format available on your TV Monitor and
utilize this for your Monitor OUT connection from the T 765 to the TV Monitor. In most cases this will
be Component Video, but on some older TV’s S-Video may be the best quality connection. See also
the item “3 COMPONENT VIDEO 1-3, COMPONENT VIDEO OUT” under “Identification of Controls – Rear
Panel” discussions.
NOTES
Video signals are converted between all three formats:
• Composite, S-video and Component Video.
• All three monitor outputs will always be active no mater what the source format is.
• OSD menu is always available on all three output formats.
A/V PRESET
A particular Source can be assigned a stored Preset. The parameters set up in the selected Preset
number will be adopted into the particular Source it is assigned (Please refer to the separate section on
‘A/V Presets’ for further understanding of Preset settings).
Scrolling to ‘A/V Preset’ and by pressing and then keys, a Source could be assigned a Preset
number ranging from Preset 1 to 5.
If it is desired not to assign the particular Source a Preset setting, select ‘None’.
TRIGGER OUT
The Trigger Out for a particular Source is dependent on the configurations done in a separate menu on
Trigger Setup (See ‘Trigger Setup’ below). If all three available Trigger outputs are assigned to ‘Source Setup’
in the separate ‘Trigger Setup’ window, a particular Source can have the following Trigger Out combinations
Trigger Out ➜ 1 ➜ 2 ➜ 1 + 2 ➜ 3 ➜ 1 + 3 ➜ 2 + 3 ➜ 1+2+ 3
These combinations are dependent on the assignment of ‘Source Setup’ for ‘Trigger 1 Out, Trigger 2
Out or Trigger 3 Out’ at the Trigger Setup menu.
Another option is ‘None’ whereby the particular Source is not assigned any Trigger Out.
For ‘Trigger Out’ to become enabled and assignable at ‘Source Setup (Normal View)’ menu, make sure
to carry out or note the following beforehand
• In the separate ‘Trigger Setup’ menu, assign ‘Trigger 1 Out, Trigger 2 Out or Trigger 3 Out’ to ‘Source
Setup.’
• ‘Trigger Out’ will not appear as an option at the Source Setup (Normal View) menu if at the
separate ‘Trigger Setup’ menu, ‘Trigger 1 Out, Trigger 2 Out or Trigger 3 Out’ are all assigned to
‘Main, Zone 2, Zone 3, Zone 4, or Zone 2+3+4’; with not even one ‘Trigger Out’ port allocated to
‘Source Setup.’
