Configure SMPTE ST 2110 output

The Receiver service on the RX1 can output uncompressed digital video signals and associated audio and data using SMPTE ST 2110 via the optional Mellanox X5 network interface card. This allows the individual media essences normally encapsulated in an SDI bitstream to be transmitted as individual IP streams.

SMPTE ST 2110 requires the use of a PTP (Precision Time Protocol) clock. Currently, setup for this is only possible via the front panel.

It may also be required to modify the server performance profile by setting an alternative output profile. See Configure the output Profile.

License Mellanox X5 card

When ordering the Mellanox X5 card for an existing RX1 it will need to be licensed.

To obtain and enable the license the following steps must be performed:

1. Connect to the RX1 unit using one of the following options:

   • Use an SSH connection.
   • Connect a mouse and keyboard directly to the unit.

2. Use the login credentials below:

   • Username: mfeng
   • Password: 2u4y&C

3. Type the command:

   sudo lspci -vv | grep "Serial number"

   The unit serial number should be seen, for example: Serial number: MT2038K20657.

4. Provide the serial number to MediaKind supply, SW.Supply@mediakind.com. License key file is provided.

5. Rename the file to rivermax.lic.

6. SCP onto the unit and place the file into /opt/mellanox/rivermax/rivermax.lic. License is enabled, SMPTE ST-2110 is enabled.

Configure SMPTE ST 2110 output

Before you start, ensure:

• At least one Receiver service is configured.
• The following option is present: MKP/HWO/PCI/NIC/25GDUAL

To configure an SMPTE ST 2110 output, follow these steps:

1. From the Home page, select the RECEIVER item from the required feed then click .

2. From the Parameters section, select the Output tab.

3. If an SMPTE ST 2110 tab is not present under the Output tab, click the + to add an output. Select SMPTE ST 2110 from the pull-down list in the Add Output pop-up box then click the Add button.

   If a UHD SMPTE ST 2110 output is created, then all other outputs must be deleted as the UHD service only supports a single output.

4. Complete the Video, Audio, Data, and Essence parameters.

5. When two or more output exists, additional outputs can be deleted using the x button on the Output tab.

Configure SMPTE ST 2110-20 video output

To configure SMPTE ST 2110-20 video output, follow these steps:

1. From the SMPTE ST 2110 tab, select the Video tab.

2. Select the required Dynamic range signalling and failure mode options.

3. Configure the output essence.

Configure SMPTE ST 2110-30 audio output

To configure SMPTE ST 2110-30 audio output, follow these steps:

1. From the SMPTE ST 2110 tab, select the PCM Audio tab.

2. By default only one essence is configured, however, more essences can be added by selecting + next to the Essence 1 tab.

3. Use the Add component, Add all and Remove all buttons to add the required number of decoded audio components to the list of output components.

4. Use the Component pull-down list on each component to select the decoded audio component to be output as part of the SMPTE ST 2110-30 audio stream.

5. Use the Embedding pull-own list on each component to select the essence to embed the component into.

6. Configure the output essence.

Configure SMPTE ST 2110-31 audio output

To configure SMPTE ST 2110-31 audio output, follow these steps:

1. From the SMPTE ST 2110 tab, select + next to the Video, Audio and Data tabs to add a new tab.

2. Select AES3 Audio as the type for the tab.

3. By default only one essence is configured, however, more essences can be added by selecting + next to the Essence 1 tab.

4. Use the Add component, Add all and Remove all buttons to add the required number of decoded audio components to the list of output components.

   When using multiple essences it is best to use Add Component and then select the required essence for that component.

5. Use the Component pull-down list on each component to select the passthru audio component to be output as part of the SMPTE ST 2110-31 embedded audio stream.

6. Use the Embedding pull-own list on each component to select the essence to embed the component into.

7. Configure the output essence.

Configure SMPTE ST 2110-40 data output

To configure SMPTE ST 2110-40 data output, follow these steps:

1. For each available data type, select either OFF or the line number that the data should appear on.

2. Configure the output essence.

Configure SMPTE ST 2110 output essence

For each media type configured for the SMPTE ST 2110 output, configure the essence output by following these steps:

1. From the Essence tab, enable the output by ticking the Output enable checkbox.

2. Set a value for the Payload type.

3. On the Primary tab:

   1. enter the destination IP address and port for the stream.
   2. Select the network interface from the options in the pull-down list.
   3. Either leave the source port setting on Auto or enter a valid value.
   ⚠️

   The Secondary source port will use the same value for source port as the Primary setting. This is due to a driver limitation that may be resolved in future releases.

   4. Set a value for the TTL parameter.

4. To support SMPTE ST 2022-7, a secondary stream can be output that is a duplicate of the primary stream:
   Click + next to the Primary tab and set the values for the output on the Secondary tab.

5. Click Save and continue to save your changes.

Download SDP file

The SDP (Session Description Protocol) files that describe each SMPTE ST 2110 essence are generated each time the essence parameters and source input are changed. These SDP files can be used to configure the inputs of equipment that are required to receive the SMPTE ST 2110 essence streams.

The SDP file for each media type can be obtained by clicking in the Output status section. This appears on the Stats page and on the Edit page for the Output.

It is advisable to wait 30 seconds after setting up an essence and providing a source stream before downloading the SDP files to ensure the SDP file is fully updated.

NMOS Support

Once the required service has been started, SMPTE ST 2110 outputs can be discovered using products that support the NMOS IS-04 Discovery and Registration standard. In addition, active SMPTE ST 2110 outputs can be managed using products that support the NMOS IS-05 Device Connection Management standard.

mDNS Configuration

The RX1 receiver service supports the ability to use multicast DNS (mDNS) protocol to resolve domain names within the attached SMPTE ST 2110 network.

This can be enabled from the GUI of the RX1 via the NMOS tab on the appliance page:

1. From the Home page, select the RECEIVER item from the required feed then click .

2. Click the RX appliance tab.

3. Click the NMOS Tab.

4. Enable the checkbox as shown below:

   

   NMOS basic settings also include:

   • Label: This is the label used for the device when used as an NMOS node.

   Further advanced settings are available:

   • mDNS multi-label domains: When selected, you can enable mDNS to support domains with multiple labels.

   Example: en.mediakind.local, where en is subdomain of mediakind.local.

   • DNS priority (pri): This is used for the 'pri' TXT record when advertising the node via mDNS.
     Specifying 2147483647 (maximum value) disables advertisement completely.

   • Registration Server highest Priority: This is used to specify the highest 'pri' value of discovered registration server, to avoid development and live systems colliding.
     Smaller numbers indicate higher priority; 0 is highest priority.

   • Registration Server lowest Priority: This is used to specify the lowest 'pri' value of discovered registration server, to avoid development and live systems colliding.
     Larger numbers indicate lower priority; 2147483647 is lowest priority.
