SRG-4400 User Manual (Iss. 06) Menu System • 5–13
Frame and Sub-carrier offsets only appear when PAL or NTSC is selected on Composite 1, Black
1 and the Tri-black outputs.
Each of these fields is editable. Together with the timing offset in the top row, these fields enable
the user to apply offsets rapidly to individual video outputs.
Pattern Number
This menu pair allows the user to select the pattern for the video output they are operating on. The
options in the field are 0 up to the maximum number of patterns allowed for the output being
configured.
Patterns are selectable on: SDI 1 output, SDI 2 output, and Composite 1 output.
Additionally, patterns may also be selected to appear on the SDI Black outputs (same pattern as
selected on the associated Pattern outputs).
All other outputs normally produce only Black.
Each pattern generator is independent in both format and pattern. So, for instance, SDI 1 can be
outputting a RP219 bars in 1080i 60Hz while SDI 2 is outputting Pathological Test in 720p 24Hz
and Composite 1 is outputting SMPTE bars in NTSC-M.
The list of available patterns in each format can be different. Some patterns are format specific,
and so do not appear in the list for other formats, e.g. the SDI specific Pathological test pattern
does not appear in the list for an analogue NTSC output.
Pattern descriptions are as detailed as possible within the limitation of 30 characters.
The list of patterns is constantly changing as we add more patterns to the Pattern Library. These
new patterns can be uploaded to your SRG-4400 over the Ethernet interface. You will need to
find some maintenance time to do this as a power cycle may be required
ID Memory, Character, Description
This menu triplet allows the user to select and edit the ID Text/Image for the video output they are
operating on.
ID Text/Image is selectable on: SDI 1 output, SDI 2 output, and Composite 1 output. Each of the
three outputs has a separate set of ID Text/Image memories. When the ID Memory is selected to
be ordinary text, the options in the field are 1 through 3. These are ID text memories. Each
memory is edited individually. This field selects which memory is 'active' and hence enabled and
editable in the menu. When “n” is selected in the ID Memory line, “n” in the Character line
follows.
The options in the next field are: 01 through 30. There are a maximum of 30 characters in each ID
text memory. This field selects which character is 'active' and hence editable in the menu. In the
selected “
Description
” line, as this field is changed, a cursor gives a visual indication of which
character is active.
The options in the third field are: 000 through 255. There are 256 characters in the extended
ASCII font. Each ID character is edited individually. This field is adjusted to display the required
character in the selected ID Text memory.
Not all the characters 000 through 255 are allowed. The ones that are no allowed are
automatically skipped.
Notes:
• After adjusting the field “yyy”, use the Escape/Back button to select the next character to
edit, then press Select to edit the next character, etc.
• When using the available front panel controls, editing of the characters in ID text
memories is performed in Overtype mode (e.g. it is not possible to Insert or Delete
characters).
