Cloud Streaming - Classroom Presentation Board Playback Issues

Issue: Swank Motion Picture video streams require that the playback devices support Widevine Digital Rights Management (DRM).  Customers have reported that classroom presentation boards listed below may not support the required DRM. 

• Promethean
• Vivi*
• ViewSonic Viewboards
• Newline**

Cause: This can occur when the playback equipment is using the internal Android operating system on the presentation board and DRM is not supported. 

Alternative Solution

We suggest using another device such as a laptop or desktop computer as a streaming source and using the external video input on the equipment to facilitate playback. This should bypass the internal operating system and use the board simply as a monitor. 

If you are using a laptop and the output is still an issue or you are getting an HDCP error, you can change your monitor settings from "mirror" monitors to "extend" monitors and drag the playback window to the external screen. This should allow playback without error. 

How do I Confirm Widevine support for my device?

The simplest way to verify Widevine DRM support on an Android device is to install and run an application called DRM Info (linked below)

Here's a screen shot of what the relevant details look like on an Android phone for example -

 
As you can see in this image, this device supports Widevine Level 1 DRM.  There are three Widevine DRM levels. 

Widevine Level	Security Type	Typical Devices	Max Resolution
L1	Hardware-based (TEE)	Certified Android devices, TVs	Up to 4K
L2	Mixed	Some Android / embedded systems	Usually 720p–1080p
L3	Software-only	PCs, kiosks, touch panels	Usually SD–720p

 
If a device reports L3 support, we still recommend performing a playback test on the device using your Swank streaming portal.
