Presentations

The Presentation (created in the SubC Streaming Service web application, Menu → Presentations) must be assigned to a Channel and Streaming in order for the Presentation to be available to the Stream Channel as Presentation Input.

Below is an overview of the Presentations Input in the Stream Desktop UI

Presentations using Transmission Type: Smooth

Sending Side Stream Desktop Channel Menu → Streaming Video → Transmission Type: Smooth

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

Ignore Access Code - Optional

If you prefer not to have to enter a Presentation Access Code when you are using Presentation as Input to your Channels, you can select Menu → Settings → Admin Settings -->Ignore Access Code

Ignore Access Code only applies to Channel → Presentation Input; The Presentation Viewer web application still requires your invited viewers to authenticate with their email address and Presentation Pass.

Select Menu → Settings → Admin Settings → Ignore Access Code

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

Using Presentation Input - Example

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

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

Below is an image of Stream Channel 1 Streaming video to a Presentation called “SubC Stream Presentation” and Channel 2 is configured with Presentation Input type, taking the “SubC Stream Presentation” as its input.
