Grass Valley iTX System v.2.6 - Manual (Page 162)

Configuring channels
Note:
• For iTX to work in this way, the operator must select the Allow External Takes option for
the sequence in the Event Editor.
• It is not possible to have SCTE104 and Enhanced SCTE104 enabled at the same time.
Enhanced SCTE104
The Enhanced SCTE104 output server controls provide additional VANC commands and
increased functionality compared to the standard SCTE104 output server controls. This
includes:
• Processing of Multiple Operation Messages, which allows for both Local & National Avail
Insert Commands and the ability to react to legacy DTMF triggers.
The following additional commands are supported when included as a part of a Multiple
Operation Message.
• splice_request_data
• splice_insert_type
• Pre_roll_time
• splice_event_id
• insert_segmentation_descriptor_request_data (which identifies local or
national avail)
• insert_DTMF_descriptor_request_data
• The pass through of SCTE messages is also extended to include:
• All inbound SCTE104 Messages can be either passed through or blocked.
• Support for the following SCTE 104 messages, when received as part of a Multiple
Operation Message:
• splice_request_data()
•
time_signal_request_data()
•
insert_avail_descriptor_request_data()
•
insert_DTMF_descriptor_request_data()
•
insert_segmentation_descriptor_request_data().
• The ability to enable and disable pass-through messages.
• When pass-through is enabled, iTX allows for the passing of “NULL” SCTE
messages for heartbeating to downstream services.
• Support for enabling or disabling pass-through applies to all commands within a
Multiple Operation Message, not just individual splice_insert_type level
commands.
• Splice commands received outside of a configured available window are
unchanged.
• Outbound SCTE messages support the following additional operations:
• insert_segmentation_descriptor_request_data (which identifies local
or national avail)
• insert_DTMF_descriptor_request_data
