Presentation Input

Presentation Input in SubC Software takes an active Streaming Presentation as its video input source.

Presentations are created & configured in SubC Streaming Service Web application in Menu → Presentations and are accessible in SubC Software desktop applications as Presentation Input.

A subscription to SubC Streaming Service is required for this Presentation Input function. If you do not have SubC Streaming Service subscription, please contact sales@subcimaging.com.

The Presentation must be assigned to a Channel and Streaming in order for the Presentation to be available to the Channel as Presentation Input.

If your company has subscribed to Streaming Services and you have activated your SubC Software host PC with your Streaming Service Group, you will be able to proceed with configuring your Channel with Presentation Input.

Activate

If the Activate prompt appears when you select the Presentation Input this may mean:

You have not subscribed to SubC Streaming Services. Click the link in the prompt message “Click here to find out more”
You have a SubC Streaming Service subscription, but your SubC Software host PC is not yet activated with your SubC Streaming Service Group
- Open SubC Streaming Services web application, click the green “+” circle to obtain an Activation Code, then copy/paste the Activation Code on the line in the Activate box and click OK.

Presentation Stream

One-Time Stream

Note how the options are different when One-Time Stream is selected.

You must Sign In to your SubC Streaming Service Account, then the One-Time Stream Address field will appear.

Then paste the Once-Time Stream URL in the Address field and click Start. (Obtain the One-Time Stream URL from a member your Report Operations team who started the Channel streaming to the One-Time Presentation)

See One-Time Stream page for more details.

Back arrow – Returns to the Input selection window.
Presentation Stream - Select if you want to connect to a regular Presentation (not a One-Time Stream)
One-Time Stream - Select if you want to connect to a One-Time Stream.

Continuing with regular Presentation Stream Input overview…
Refresh - Click to reload the list of currently streaming Presentations if you do not yet see the name of the Presentation to which you want to connect.
Presentation – Drop-down field shows a list of Presentations created in your SubC Streaming Service Web application Group from which you can select.
Source - Select the Channel that is streaming the video to the Presentation
The Presentation you select must be active, currently streaming. An active Presentation & its source Channel is identified by a green illuminated button in front of the Presentation Name.
Access Code - Enter the Access Code for the selected Presentation.
1. A unique Access Code is assigned to each Presentation created in the SubC Streaming Service web application to ensure only those who you invite to your Presentations can login to the Presentation Web Viewer to view your presentation.
2. However, Presentation Access Code can be made optional, see Ignore Access Code - Optional, below.
Start – Click Start button to begin the input Source with selected settings
Start button remains disabled until the valid Access Code is entered, unless Ignore Access Code has been selected, in which case you will not require an Assess code.

Presentations using Transmission Type: Smooth

SRT Receiver Latency Low | Medium | High

If you have selected a Presentation that is streaming via Transmission Type: Smooth, once the Presentation and Source is selected, the SRT Receiver Latency Low | Medium | High buttons appear. These settings allow you to adapt to variations in your Network quality.

You can select Low = 2s, Medium = 5s, High = 10s - whichever best suits your current Network conditions. For example:

If you have optimal Network conditions, low dropouts, less buffering required, select Low for 2 seconds of buffering.
If you have less than optimal Network conditions and need more buffering, select Medium for 5 seconds or High for 10 seconds.

Ignore Access Code - Optional

Select Menu → Settings → Admin Settings → Ignore Access Code

You can also use a Presentation as an input to a Channel, so we’ve made Presentation Access Code optional as a convenience for this specific purpose.

Check Ignore Access Code. When Ignore Access Code is checked on, the Presentations Input selection window will omit the Access Code field.

Select an active Presentation and its Source Channel [Ignore Access Code is on], Click Start

Show Media Capture Wizard checkbox

Checked → When the Start button is clicked, the input video feed will start and the Media Capture Wizard will appear.
- You can then configure your Blackbox and Recording directory and file settings preferences
- Or you can click Cancel Wizard button (in this case BlackBox or Media Capture configuration panels will not appear) and the video input will display.
Unchecked → When the Start button is clicked, the input video feed will start the video input (without presenting the Media Capture Wizard.

Example: For demonstration purposes only - This is not a typical use case.

Below is an image of the DVR+O Channel 1 Streaming video to a Presentation called “DVR+Ov7-Presentation” and Channel 2 is configured with Presentation Input type using the Presentation named “DVR+Ov7-Presentation”.

Typically, the Streaming Channel would be configured on another PC running a SubC Stream enabled application. In this example we are using the same DVR+O desktop application to illustrate a sending side Streaming (Channel 1) and receiving side using Presentation Input (Channel 2).
