The device usually communicates via Virtual and listens to incoming connections on port 9000.
Supported Features
This protocol allows to configure up to 6 Virtual Inputs and the Active Input Select.
Supported Commands
| /api/activeInput | GET/POST |
|---|---|
| /api/inputConfigure | GET/POST |
Configuration Details
The user can specify the poll time via the Web UI. If the Flow.Port parameter needs to be “any” please set the value to “0”. The parameter RTP Payload Type is used in ST2110-20 mode.
Configuration Details for Hybrid SDI and 2110 Environments
NOTE: You must be on Prism Version 3.3.2 or higher in order to apply this configuration.
In previous versions of Prism, the following issues can occur:
- Losing NMOS receiver in PRISM by changing the input to SDI will lose the visibility of PRISM unit in the LAWO system.
- LAWO system doesn’t use API commands unique to PRISM.
- Operator will interact input button on the PRISM front panel to change monitoring between SDI and IP.
- The transport assignment (SDI or IP) on each input on the PRISM front panel must be unchanged.
- In the current workflow, selecting "IP" input on the PRISM front panel will make NMOS receiver appear in the LAWO system. But when operator did it, the previous streams coming up for monitoring causes confusion on the operator. This is the issue you would resolve.
This workflow can cause the following when comparing IP program and SDI program in previous version :
- Operator is now monitoring SDI signal assigned to “SDI” input.
- Operator may select IP stream from control panel.
- Operator may select “IP” input, then the streams selected in #2 should come up for monitoring.
What has been applied in the latest version based of this workflow is the following:
#1 PRISM NMOS receiver to be available all the time even while operator is monitoring SDI signal.
#2 NMOS patch should happen on a manually specified input even while operator is monitoring SDI signal.
For #1, Telestream added a selection of "Persistent Receiver” in Setting menu (Setting->Network->NMOS) to make NMOS receivers to be available always. Turn this on to enable this.
For #2, Telestream added Radio Buttons, “Target Input”, to let user to select an input to apply NMOS Patching. The selected input will always get NMOS patching.
See attached UI image for reference.
These two updates will allow above process #2, “Operator may select IP stream from control panel“ even while operator monitors SDI signal".
