Encoder: Input

This section is dependent on how the program is ingested by the Volicon Media Intelligence service. Currently, there are four types of video acquisition.

  • Video input: Capture card used to interface Volicon Media Intelligence service to program source

  • Transport Stream (TS): IP-based direct program access

  • Cloud: IP-based, typically via CDN streaming

  • Device direct: Tethered cell phone acquisition

Table: Video input profile (capture card and Transport Stream)

External switch output

If external A/V switch used, entry specifies which switch output port feeds associated encoder input, assuming switch has more than one output port; set value to 1 if external input switch not used

Restart on input recovery

Automatically restarts encoder when its input is recovered; relevant for Blackmagic cards only to avoid timestamp issues

Signal loss restart interval

During periods of no input, encoder automatically restarts at specified interval to avoid time stamp issues

Video device name

Text string with the card name and channel ID if the card supports multiple channels

Name

Required text field

Connector type

Dropdown used to select video connector

Format

Dropdown used to select type (i.e., PAL-B 1080i, frame rate and resolution)

Add format

Used to open dialog to create another format

Table: TS input profile (IP ingest section)

Host

IP address or URL of the program source

Port

IP port address to access the program

HTTP node name

The name of the HTTP node, as configured in the Mediahub, for streaming data of the required PID

Storage node name

The name of the storage node, as configured in the Mediahub, where data for the required PID is stored

Program name

The name of the program to encode the TS stream

Close gaps from cache

If encoder losses feed, it keeps recording black screen until feed returns; allows downtime to be represented in the recorded data

Detect PAT/PMT events

Depreciated, no longer used

Handle PAT/PMT events

Depreciated, no longer used

Handle XDS events

System to process Extended Data Services events and log them

Stop on scrambled

Ignores encrypted streams so Volicon Media Intelligence service does not generate erroneous alerts

Enable low-bitrate streams

Enable/disable handling of low-bitrate streams; usually disabled due to slowing down of recovery in event of connection loss; to be enabled if nearly no payload (e.g., black video); this should be enabled
