Dash.encrypt Segmenter from castLabs

Dash.encrypt Segmenter from castLabs | DRM video | Scoop.it

Usually when creating a video, all that is needed is to encode it using a codec (for example H.264 or HEVC). However, to transmit a video using MPEG-DASH, an extra segmentation step is required. Typical encoders do not provide this step and produce content which is not compatible with DASH.

 

Our dash.encrypt project provides a solution. It takes encoded video and audio from an array of different formats and repackages them as valid DASH streams. It also generates the required manifest which is the table of contents for the stream.

 

Hosted as a GitHub project, it is available as an open-source application written in Java. We provide everything you need to start creating DASH content and invite you to help refine the program.

Reducing Complexity of Multiscreen Video Services with PlayReady and MPEG-DASH

Reducing Complexity of Multiscreen Video Services with PlayReady and MPEG-DASH | DRM video | Scoop.it

Adaptive streaming protocols need to be integrated with content protection schemes. PlayReady was originally designed to work with Smooth Streaming. It has also been integrated with HLS, which is probably the most popular of the proprietary adaptive streaming schemes. Integration of PlayReady with MPEG-DASH is likely to be viewed as a safe choice, in line with the way the industry is going. That solution came into view this month as BuyDRM and Fraunhofer IIS announced an integration of MPEG-DASH with PlayReady for the HBO GO service in Europe. HBO GO is HBO’s “over the top” service for subscribers.

Intertrust’s Wasabi Marlin Client SDK v.1.3 supports MPEG-DASH multi-screen streaming [PR]

Intertrust’s Wasabi Marlin Client SDK v.1.3 supports MPEG-DASH multi-screen streaming [PR] | DRM video | Scoop.it

Recognizing the growing demand for a standards-based streaming technology for Over the top (OTT) content delivery, Intertrust today announced a new version of its Wasabi Marlin Client SDK that supports MPEG-DASH (Dynamic Adaptive Streaming over HTTP).

[...]

 

Intertrust’s Wasabi Marlin Client SDK v.1.3, available immediately, is a complete Software Development Kit (SDK) for developing media applications based on the Marlin DRM standard. Wasabi allows quick and efficient deployments based on Marlin DRM on desktop (PC and Mac), mobile (iOS and Android), and embedded systems (set top box and connected TV), with support for MPEG DASH and Common Encryption on all those platforms.

Marlin-DRM protected DASH POC : MMSys 2011 Ericsson research paper

Marlin-DRM protected DASH POC : MMSys 2011 Ericsson research paper | DRM video | Scoop.it

Dynamic adaptive HTTP streaming (DASH) is a new concept for video streaming using consecutive downloads of short video segments. 3GPP has developed the basic DASH standard which is further extended by OIPF and MPEG. In all versions available to date, content protection is not properly enabled. Extensions are needed to enable important use cases like pay-per-view, license change in an ongoing video channel, and pay-per-maximum-quality.


In this publication, Frank Hartung, Sinan Kesici and Daniel Catrein have examined which extensions are needed, in order to use DASH for DRM protected content. This comprises required changes in the DASH standard, namely MPD metadata extensions, as well as changes in the used transport file formats, namely the inclusion of a ISO file format box carrying a segment key, and finally a suitable key and license structure applied to the underlying DASH concept. All those changes have been proposed and explained in the paper. With these changes and additions, which do not change the core idea of DASH, even more complex use cases like pay-per-view and pay-per-maximum-quality are possible. As a proof-of-concept, the authors have implemented the proposed changes and integrated them with a real DRM key and license management system. For the proof-of-concept, they have used Marlin DRM, but any other similar DRM would be equally usable.

Content Decryption Module Interface Specification: An open interface for enabling HTML5 Encrypted Media Extensions in open source browsers

Content Decryption Module Interface Specification: An open interface for enabling HTML5 Encrypted Media Extensions in open source browsers | DRM video | Scoop.it

The W3C HTML working group is developing media extension specifications for HTML5 to enable the delivery of commercial video to consumers over the Web. One of these is the Encrypted Media Extensions (EME) specification. The current specification describes an open interface which may be used to implement an EME-compliant Content Decryption Module (CDM) within a User-agent, providing access to a platform DRM component which supports the defined Content Decryption Module interface (CDMi).

HbbTV improved adaptive streaming

HbbTV improved adaptive streaming | DRM video | Scoop.it

The HbbTV (Hybrid Broadcast Broadband TV) consortium has announced the publication of version 1.5 of its hybrid TV specification. Building on existing standards and web technologies, the HbbTV specification provides the features and functionality required to deliver feature rich broadcast and internet TV services.

 

Version 1.5 of the HbbTV specification notably introduces support for HTTP adaptive streaming based on the recently published MPEG-DASH specification, improving the perceived quality of video presentation on busy or slow Internet connections. It also enables content providers to protect DASH delivered content with potentially multiple DRM technologies based on the MPEG CENC specification, improving efficiency in markets where more than one DRM technology will be used. Version 1.5 significantly enhances access to broadcast TV schedule information, enabling operators to produce full seven-day electronic programme guides as HbbTV applications that can be deployed across all HbbTV receivers to provide a consistent user experience. The latest advances are based on activity within the HD Forum in France as part of the development of the TNT 2.0 specification

Netview Technology Media Client SDK - Smooth, DASH and PlayReady support for iOS and Android apps

Netview Technology Media Client SDK - Smooth, DASH and PlayReady support for iOS and Android apps | DRM video | Scoop.it

Input media formats:

- Smooth (VoD & Live). An adaptive HTTP format specified by Microsoft. Used by Microsoft in Silverlight, but is an open format that third party clients also support.

- Apple HLS (VoD & Live). An adaptive HTTP format specified by Apple. Used by Apple in iPhone/iPad, but is – like Smooth – an open format.

- MPEG DASH (VoD). A new adaptive format specified by ISO. Wide and promising industry backing. We support both MPEG-2 TS and MP4-based (ISOBFF) profiles.

 

Input DRM formats:
- Microsoft PlayReady DRM
