Prerequisites

• You need to purchase additional licenses for this function. Please contact your local dealer.

• Either registered devices or IP streams can be served as inputs/outputs.

• Add IP stream inputs referring to Manage Input Streams.

• Add IP stream outputs referring to Manage Output Streams.

• Registered devices models refer to Supported Products.

• Total number of all outputs of all channels is limited by the License "Active Outputs" which you can find in the "Settings > License > Authorized Info" section.

• In the Control Hub deployed on a Linux system, after each channel is successfully added, it automatically generates an NDI® stream (requires specifying the NDI discovery server address). The number of NDI® streams does not count toward the License's "active outputs".

1. Enter the Streaming > Channels page from the navigation pane.
2. Check current streaming conversion work status from the banner. Click the right arrow at the end of the banner to get the detailed bandwidth usage.
3. Set up a channel.
   • To create a channel: click on at the upper right, specify a case-insensitive channel name containing 1 to 64 characters, then save your configuration.
   • Click Advanced Settings to configure NDI stream parameters:
     • Enable NDI Output: The default state can be set in General > Default NDI Output Enable. When the switch is toggled on, NDI streams will auto-sync transmit when this channel is opened. (Linux systems only)
     • Group Name: Defaults to public. Group names are case-insensitive and support A-Z, a-z, 0-9, and special characters (including _-). The converter allows sending to multiple groups simultaneously—set values separated by English commas (e.g., group1,group2).
     • Transport Mode: options are Auto (default), UDP (Unicast), UDP (Multicast), RUDP (Unicast), TCP (Single Connection), TCP (Multi-Connection).
       • UDP (Unicast): Transmits to receivers via UDP protocol in unicast mode. Achieves lower latency, and multiple receivers can simultaneously receive streams without interfering with each other.
       • UDP (Multicast): Transmits to receivers via UDP protocol in multicast mode. Suitable for scenarios requiring simultaneous transmission to multiple receivers. The encoder only needs to send one stream, reducing CPU utilization. Parameters:
         • Multicast IP: 224.0.0.0 ~ 239.255.255.255
         • Multicast Mask: Set according to the network configuration. Valid values range from 255.0.0.0 to 255.255.255.252.
         • Time to Live (TTL): 1 ~ 255 (default: 1)
       • RUDP (Unicast): Transmits to receivers via RUDP (Reliable UDP) in unicast mode. Optimizes connections, maximizes bandwidth utilization, and adapts to weak network environments by enhancing transmission at the application layer.
       • TCP (Single Connection): Establishes a single TCP connection with receivers, transmitting audio/video packets through the same port. Provides lower CPU utilization compared to UDP (Unicast) and TCP (Multi-Connection) under similar streaming conditions. Offers more reliable connections and ensures stable 4K NDI streaming.
       • TCP (Multi-Connection): Establishes multiple TCP connections with receivers, transmitting audio/video packets through different ports. Performs better in complex network environments while maintaining TCP's reliability advantages, ensuring stable 4K NDI streaming.
     • After enabling NDI Output, the NDI discovery server address must be configured for functionality.
     • Stream Key and Playback Key are auto-generated.

   • To edit your existing channel: click and enter channel settings page.
   • To delete a channel: click Delete from the droplist shown as below from the Channels list.
4. Set up your input.
   • Use the created channel as a streaming server.

     There are "Stream key" and "Playback key" for RTMP/SRT streaming services. Get stream links as below.
   • To add an input: click below Input from the Channels list or on the channel settings page and select an input from Devices list or Presets, or add a preset.
     

     Add IP stream inputs to Presets referring to Manage Inputs Streams.

     The Push links of the Control Hub fail after you add an input, but the Play links still work.
   • To switch an input: click behind Input from the Channel bar and select another input from Devices list or Presets.
     

     Add IP stream inputs to Presets referring to Manage Inputs Streams.

   • To modify parameters of input connection for device input: enter channel settings page and click the , set the parameters below.

     • Protocol: device uses Default(RTMP) to communicate with Control Hub, options are RTMP, SRT.
     • Stream: choose from Main stream and Sub stream when Protocol is RTMP or SRT. And you need to turn on the Sub stream function for the device when here uses Sub stream.
     • Latency: specify SRT latency. The range is from 20 to 8000ms, and the default is 120ms.
   • To delete an input: enter channel settings page and click Delete shown as below.
5. Set up your output(s).

   • To add output(s): click below Output and select one or more outputs from Devices list or presets, or add a preset.
     

     Add IP stream outputs referring to Manage Outputs Streams.

   • To modify parameters of output connection for device outputs.

     • Protocol: device uses Default(RTMP) to communicate with Control Hub, options are RTMP, SRT.
     • Latency: specify SRT latency. The range is from 20 to 8000ms, and the default is 120ms.
     • Buffer duration: specify RTMP/SRT buffer. The range is from 1 to 5000ms, and the default is 120ms.
   • To delete an output: enter channel settings page and click "X" shown as below.
6. Start/stop your channel.

   Toggle on/off the switch of target specific channel(s) on the Streaming > Channels page.

   Then you can check the working status of your channel. Click on the thumbnail preview area, then you can get enlarged video preview.
