Selenio X100
Installation and Operation Manual
The X100 can also create SCTE-104 VANC packets when it detects an RS-232/RS-422/
RS-485 serial input data containing SCTE-104 multiple operation messages with splice
request messages or DTMF descriptor request messages. The VANC packet is inserted into
the video on the next available video field after the message is extracted from the serial
input data. The serial data must use the Basic Link Layer Syntax to carry the message, as
well as provide message synchronization The message data is carried in binary form.
SCTE-104 Extraction
The X100 extracts and decodes SCTE-104 VANC packets, and also trigger GPIO outputs. A
maximum of 8 GPIO outputs (configurable and shared with GPIO inputs) are supported.
Two extraction (decode) modes are supported: Static and Dynamic.
If the SCTE-104 decode mode is set to Static, (GPI and Rules Engine > GPI > GPI Output
> SCTE104 > BT1685 GPI Out Processing > GPI Delay & Hold Processing Mode), the
GPIO output 0 will be triggered whenever an SCTE-104 message is received from the VANC
space. The GPIO output pulse width and delay will be generated according to the user
specified GPI static hold and delay parameters. (For Static decode mode, only GPIO output
0 is triggered.)
If SCTE-104 decode mode is set to Dynamic, you can configure the X100 to extract a
specific item of the message, and then decode the value of that item to determine which
GPIO output to trigger. For example, if the X100 is configured to extract AS_index for the
GPIO outputs, then GPIO port 0 will be triggered if AS_index is 1.
Port 1 will be triggered if AS_index is 2; port 2 will be triggered, if AS_index is 3, and so
on. The table below lists all the items that can be decoded, as well as the mapping of item
values with GPIO output ports:

Note: The generation of the GPIO outputs will be aligned to the next start of field of the
selected input video (instead of output video).
