625 Input - 625 Output
You can select which input lines of WST are encoded on the output (see instructions for SD
VBI line setup below). For the lines selected the status of WST being detected on that line is
reported back.
The unit allows for up to 15 lines of WST to be selected on the input. If valid WST is detected
on the selected lines, they will be placed on the same lines on the output. The status for each
line will be reported back.
It is also possible to remap one WST origin line. In this case, select Allow WST remap (see
menu list table on page 87). If valid WST is detected on the line selected by “WST origin line”
it will be put on the line selected by the user control “WST output line”.
625 Input - HD Output
In applications where the video is upconverted, you can select which lines of WST are
encoded.
1.
If RDD08 (OP47) conversion is selected, then up to 15 lines can be encoded in the
RDD-08 packet. A maximum of 3 packets are allowed on the output, each with
individual line number controls. The number of output RDD-08 packets on the output
is decided by the number of valid WST lines decoded on the input. The first five WST
lines are encoded in the first RDD-08 packet, the next 5 in the second RDD-08 packet
and so on.
2.
If SMPTE2031 conversion is selected, then the first 5 lines selected on the input are
encoded in the 2031 packet. Each single WST line corresponds to one SMPTE2031
packet on the output. All packets will be placed on the same line selected by the user
control (see control Output Line All PKTs in the menu list table on page 87). The Data
Unit ID can be set to Teletext, Non-Teletext or Inverted Teletext.
HD Input - HD Output
You can select which input HD WST packet is to be decoded - RDD-08 or SMPTE2031.
Cross-conversion between the packet types is allowed. The option to select individual WST
lines contained in the input packets is still available using the WST origin and status menu
items. This is because both the SMPTE2031 and RDD-08 packet contain within them the
original source SD line number information. The input line selection refers to this line number
and not the ANC packet position line number.
HD Input - 625 Output
You can select which input HD WST packet is to be decoded - RDD-08 or SMPTE2031. You
can specify which lines of WST to encode on the output using the WST origin and menu item.
The WST lines will be encoded on the line number information encoded within the input HD
packet, unless “Allow WST remap” is selected in which case you can change the line number
for one WST line on the output (similar to the SD to SD case described above).
Note:
Only one WST origin line may be remapped

Only one WST origin line may be remapped
