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 (Output Line All PKTs). The Data Unit ID can be set to Teletext Subtitle,
Teletext Non-Subtitle 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 previously).
5.13.3 SMPTE 2020 Output
SMPTE 2020 Output: Selects the output line on which to insert a SMPTE 2020 VANC packet
if the output is enabled. The range is from line 8 to line 20 in one-line steps. Preset is line 10.
It is possible to set a forced association in the SMPTE 2020 metadata which sets the
Secondary Data ID (SDID) values used to identify the VANC packets to 45/02 (pair 1).
To use this control, enable “SDID Pair 1 Forced Assoc” from the Dolby menu under the
sub-menu SMPTE 2020 Output. When enabled, the outgoing 2020 data will be labelled
45/02 (pair 1).
Note:
Only one WST origin line may be remapped.
