Selenio X100
Installation and Operation Manual
63
At this time, Bar Data and Pan-Scan for VI and AFD are not supported in data embedding
and de-embedding. The X100 supports closed captioning, Teletext (OP-47), and timecode.
Other ancillary data will be stripped from the output stream, except when the X100 is in
frame sync mode.
SCTE-104
Overview
The X100 uses VANC data packets that are conveyed according to the SCTE-104 standard,
for transmission of operation messages containing SCTE-35 splice requests and DTMF
descriptor requests. These operation messages can be extracted from the RS-422/RS-232
serial data inputs, and are also triggered by GPIO inputs and outputs.
The X100 generates VANC data packets that carry multiple operation messages as defined
in SCTE-104. The UDW carries the multiple_operation_message() defined in section 7.2.3 of
SCTE-104 standard.
Although each multiple operation message can support more than one request, the X100
will only send one splice request and one DTMF descriptor request (only when requested)
per message.
SCTE-104 Insertion
The X100 supports a maximum of 8 GPIO inputs (each GPIO input is configurable but
shared with GPIO outputs). Each GPIO input can be programmed to generate a specific
splice request message and DTMF descriptor request message when triggered. For each of
the 8 GPIO inputs, the following parameters can be set by the user from the GUI:

AS_index

DPI_PID index

Time type (none or GPI)

Splice insert type (reserved, start normal, start immediate, end normal, end immediate,
cancel)

Splice event source

Unique program ID

Pre-roll time

Break duration (in tenths of sec)

Avail num

Avails expected

DTMF pre-roll time (in tenths of sec)

DTMF input
When the X100 detects a GPIO input being triggered, a VANC packet with the associated
request message will be created and inserted into the video on the next available video
field.
