Configure source error management

You can configure the encoder behavior in case of source error management. You can:

• Activate the switch on ES data loss to backup the source if video or audio input is lost.
• Configure a slate (replacement image) that will be displayed if the input is not detected at start.
• Activate the fast recovery to recover the signal faster.

Configure switch on ES data loss

Section titled "Configure switch on ES data loss"

You can activate the Switch on ES data loss to backup the source if video or audio input is lost. In case of video or audio input loss of both sources, the option selected with frame freeze management applies (see Configuring the video prefiltering).

Works both in Active/Active and in Active/Passive redundancy mode.

2. Click to edit the service. The General parameters display.
3. Select the Input tab to display parameters.
4. In the Source error management section, tick the Switch on ES data loss check box.
5. Under Delay, specify the time before switching to the backup source when loss of video or audio occurs. See Input - Source error management.

Configure a slate

Section titled "Configure a slate"

You can specify a slate (replacement image) that will be displayed if the input is not detected.

1. Display services.
2. Click to edit the service. The General parameters display.
3. Select Input tab to display parameters.
4. In the Source Error Management section, tick the Slate if no source at start check box.

The image displayed is the same as the one configured for Media Processing > Video Processing > Freeze Frame Management section.

5. Select the Default frame rate for this slate.

Configure fast recovery

Section titled "Configure fast recovery"

The Fast recovery option is activated by default.

• When checked, the encoder will process the access units as soon as possible to recover the signal faster, though temporary macroblocks may appear.
• When unchecked, the encoder will wait for the closest random access point (RAP), prioritizing video quality over signal recovery speed.

2. Click to edit the service. The General parameters display.
3. Select Input tab to display parameters.
4. In the Source Error Management section, tick or untick the Fast recovery check box depending on your needs.
