SRG-4500 User Guide (v7.0) Front Panel Menu System • 53
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, SDI 3 output, SDI 4 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 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-4500 over the Ethernet interface. You will need to find some maintenance time to do this as
a power cycle may be required.
Refer to the section “
4K UHD BNC Connections ” on page 127 for additional notes regarding 4K (Quad or 2SI)
selection.
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, SDI 3 output, SDI 4 output, and Composite 1 output.
Each of the five 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 is 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.
Keep the following in mind:
• 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).
• When you edit the pre-programmed ID Text memories, start from character position 1, then overtype with spaces
(char. #32) any extraneous characters at the end of the line.
• To quickly edit ID text memories, use the DashBoard interface. Refer to the section “ Accessing the SRG-4500
Interfaces in DashBoard ” on page 40 for details.
