Encoder - Input

This section is dependent on how the program is ingested by the MIP. MIP currently supports four types of video acquisition.

  • Video Input – capture card used to interface MIP to program source

  • Transport Stream (TS) – IP based direct program access

  • Cloud – IP based CDN streaming

  • Device Direct – tethered cell phone acquisition

Table: Video Input Profile (Capture Card and Transport Stream)

External switch output

If an external A/V switcher is used this entry specifies which switcher output port feeds the associated Encoder input (assuming the switcher has more than one output port).

Set value to 1 if an external input switch is not used.

Restart on input recovery

Automatically restart encoder when its input is recovered. Relevant for BlackMagic cards only. This is done to avoid time stamp issues.

Signal loss restart interval:

During periods of no input the encoder will automatically restart at the specified interval. This is done to avoid time stamp issues.

Video device name:

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

ADD/DELETE

Define video input parameters. If card supports multiple input channels each needs to be defined. Clicking add opens another submenu.

Volicon, a division of Verizon Digital Media Services, support is responsible for adding and deleting channels.

Video Input Misc

Connector Type

Pulldown to select video connector

Format

Pulldown to select type: i.e. PAL-B 1080i, frame rate and resolution.

Video Input External Switch

Note: not yet implemented in MIP

Remote Control

Not implemented, only supported in STB/RPM systems.
Table: Audio Input Profile (Capture Card & Transport Stream)

Name:

Card name and additional information about audio input type.

Profile

Audio profile in XML format.

Add/Delete

Add audio profiles in addition to the main audio profile.

Table: Transport Stream 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 the encoder losses the feed it keeps recording a black screen, until the feed comes back. In this way downtime is represented in the recorded data.

Detect PAT/PMT events

Depreciated, no longer used.

Handle PAT/PMT events:

Depreciated, no longer used.

Handle XDS events:

The system will process Extended Data Services events and log them.

Stop on scrambled:

Ignore encrypted streams so MIP does not generate erroneous alerts.

Enable low bitrate streams:

Enable/Disable handling of low bitrate streams. This is normally disabled because it may slow down recovery in the event of connection loss. When there is almost no payload (black video for example) this should be enabled.

Akamai access ACL:

Optional access control list (ACL) to access the server.

Key:

Preshared key (PSK) to access the Akamai server.

Audio format:

Normally set automatically based on the input feed, but may be sent manually.

Feed

Bitrate and resolution.

URL:

Channel specific URL on the CDN server.

Video format:

Normally set automatically based on the input feed, but may be sent manually.
