SMPTE ST 2022-6 output

The Receiver service on MK.IO Beam can output SDI over IP using SMPTE ST 2022-6 via the server's network interfaces.

Capabilities

Video

Video formats

The following video formats are supported:

UHD is not supported.

Video processing

The following video processing functions are available:

• Conversion of 1080p to 1080i
• Dynamic range conversion, with optional user-supplied lookup table
• Dynamic range signaling of transfer characteristics and colorimetry
• Video failure modes

Audio

Up to eight audio components, or a total of eight stereo channels, can be added.

Data

Data is embedded into the VANC (Vertical Ancillary) lines of the SDI frame before encapsulation into SMPTE ST 2022-6. It is possible to embed more than one data type onto a single VANC line.

The following data types are supported:

• VITC/Time code
• AFD/BAR
• Closed captions
• OP-47 teletext
• SMPTE-2031 teletext
• SCTE-104 splicing
• Generic data

Clock Reference

SMPTE ST 2022-6 output is synchronized to the PCR contained in the incoming transport stream.

Network card

Any network card with sufficient network bandwidth may be used.

Add SMPTE ST 2022-6 output

1. From the Home page, select the RECEIVER item from the required feed then click .
2. Check that the Configuration type is SD/HD.
3. In the Parameters window, select the Output tab.
4. Click the + button, then select SMPTE ST 2022-6 from the drop down menu.

Configure video processing

For each video processing parameter, select the required value from the drop down list.

HDR to SDR conversion custom lookup table

When the Dynamic range conversion option is set to Custom HDR to BT.709 lookup table, a custom lookup table may be specified.

Please refer to the HDR to SDR section for information on uploading custom lookup tables.

Configure audio

From the SMPTE ST 2022-6 tab, select the Audio tab.

The output audio component list is initially populated with the decoding audio components at the time the SMPTE ST 2022-6 output was created.

Add an audio component

Select Add component. A new entry is added to the audio component list.

Configure audio embedding

For the row corresponding to the output audio component to be configured:

1. Select the audio decoding component from the Component drop down list.
2. Select the position where the audio decoding component will be embedded from the Embedding drop down list (select the No embedding option to disable embedding).
3. Set the lip-sync adjustment in the Lip-sync adjustment field. Lip-sync may be adjusted in the range +/- 50 milliseconds. In low delay modes negative lip-sync adjustments may not be possible.

Remove an audio component

Click the button in the Action column for the row corresponding to the audio component to be removed.

Add all audio components

Select Add all. All the decoding audio components that are not currently included in the output audio configuration are added to the component list.

Embedded channels are allocated in sequence until all available channels are filled.

Remove all audio components

Select Remove all. All the audio components are removed from the list of outputs.

Configure data

1. From the SMPTE ST 2022-6 tab, select the Data tab.
2. Set the line number from the drop down menu for each data type.
3. Select OFF from the drop-down menu for each data type that you want to disable. Once disabled, the data is no longer embedded into the output.

SCTE-104 splicing

1. The SCTE-104 configuration is displayed when the SCTE 104 splicing line is set.
2. Apply the configuration values based on the information in the SCTE-35 to SCTE-104 section.

Configure the primary stream

1. From the SMPTE ST 2022-6 tab, select the Primary stream tab.
2. Set the Destination IP address, Destination port and Network interface.
3. Optionally, set the Source IP address and Source port.
4. Optionally, set the TTL.

Configure the secondary stream

1. Optionally, from the SMPTE ST 2022-6 tab, click the + button next to the Primary stream tab.
2. Follow the same instructions as for the primary stream to configure the secondary stream.
