castLabs’ PRESTOplay for Desktops Facilitates Secure Offline and Online Video Playback

Facilitating secure offline and online video playback as stand-alone applications for Windows® and Mac® systems. Alongside PRESTOplay for iOS and Android, this now enables content service providers to deliver multi-screen offline playback experiences usin

Berlin, Germany(17 May 2017)

castLabs, a digital video technology and services company, has announced the release of PRESTOplay for Desktops, a new video player software development kit (SDK) which provides digital rights management (DRM) enabled offline and online playback as stand-alone applications for Windows® and Mac® computers.

As video content is consumed across a variety of devices, providing native desktop and laptop player apps is an opportunity to reach users with a branded experience. castLabs’ PRESTOplay for Desktops allows video streaming services to quickly develop bespoke feature-rich players for these screens. Using HTML5, CSS, and JavaScript web technologies, just a single program needs to be written for publication on both Windows and Mac operating systems.

The comprehensive solution also takes advantage of the Google Widevine™ DRM system to enable protected studio content for VoD, live, and offline use cases. For offline scenarios, PRESTOplay for Desktops facilitates the secure downloading of both DRM-enabled MPEG-DASH content and license keys to a user’s computer to accommodate playback during travel or situations where internet is either unavailable or unreliable. The DRM feature is also compatible with Google’s new Verified Media Path (VMP) security technology.

“The launch of PRESTOplay for Desktops extends our offline playback offering across all screens,” said Michael Stattmann, CEO of castLabs. “OTT services can now deliver their own premium content streaming applications on devices where proprietary browsers were typically the only option. And importantly, they can also meet consumer expectation for offline viewing experiences without relying on aging technologies such as Silverlight® or Adobe® AIR®.”

Complementing the existing functionality of PRESTOplay SDKs for browsersiOS, and Android devices, as well as castLabs’ DRMtoday cloud licensing service, OTT providers can provide holistic, multi-platform experiences from a single supplier.
