Announcing PlayReady as a service and AES dynamic encryption with Azure Media Services

From mingfeiy.com - April 7, 2014 4:38 PM

Now Azure Media Services allow you to deliver Http-Live-Streaming (HLS) and Smooth Streams encrypted with Advanced Encryption Standard (AES) (using 128-bit encryption keys). Media Services also provides the key delivery service that delivers encryption keys to authorized users.

Azure Media Services also provides a Microsoft PlayReady license delivery service. PlayReady is a full-featured content access protection technology developed my Microsoft that uses Digital Rights Management (DRM). It protects a content media stream during playback by using a license server that provides the decryption key needed to decrypt the media stream.

Firstly, you need to pre-encrypt Smooth Streaming file with PlayReady License, by providing us License Acquisition URL, Key ID and Content Key. You could follow this MSDN article to use Azure Media Encryptor to encrypt the Smooth Streaming file. As a output, you could further package the encrypted Smooth Streaming into HLS and DASH (See how here). You could also define how the license could be authorized to your user. Similar to AES dynamic encryption, we enable Token/IP/Open authentication service.

Which platform/devices that PlayReady SDK covers?

Azure Media Services can be used to encode, download, or stream Smooth Streaming or MPEG DASH content encrypted with PlayReady. For consuming PlayReady encrypted content, client SDKsand the PlayReady Porting Kit are available under commercial licensing terms. (PlayReady clients for Windows 8.1 Store Apps can be built using the free SDK located HERE). These client-side SDKs are not part of this preview.

Will New Standards Rationalize the Industry?

From www.v-net.tv - August 24, 2011 6:56 PM

As summer draws to a close and we are all geared up for IBC 2011, a renewed focus on technical and commercial standards has emerged. While non-proprietary security standards may seem counter-intuitive (how can an open standard provide the right level of security to deliver high value content?), there are multiple benefits and clear value associated with a multi-vendor DRM scheme. These benefits have no doubt been amplified by recent progress on the fronts of multiple standards – plus the dramatically expanding landscape of multiple screens ideal for consuming video content.

The State of Streaming Media Protocols 2013

From www.streamingmedia.com - February 26, 2013 3:12 PM

It's all about DASH: Adoption is moving at a rapid pace, as industry insiders see a strong need to get DASH implemented in the field in the coming year.

The Pantos spec, as it is known in the industry, is a series of working drafts for HLS submitted by two Apple employees as an information draft for the Internet Engineering Task Force. As of the time of this article, the Pantos spec is currently at informational version 10.

Much has changed between the early versions and the most recent v10 draft, but one constant remains: HLS is based on the MPEG-2 Transport Streams (M2TS), has been in use for almost 2 decades, and is deployed widely for varied broadcast and physical media delivery solutions.

In that time frame, however, little has changed for basic M2TS transport stream capabilities. For instance, M2TS still lacks an integrated solution for digital rights management (DRM). As such, all HLS versions cannot use "plain vanilla" M2TS, and even the modified M2TS used by Apple lacks timed-text or closed-captioning features found in more recent fragmented elementary stream streaming formats.

Yet Apple has been making strides in addressing the shortcomings of both M2TS and the early versions of HLS: In recent drafts, the HLS informational draft allows for the use of elementary streams, which are segmented at the time of demand rather than beforehand. This use of elementary streams means that one Achilles' heel of HLS -- the need to store thousands, tens of thousands, or hundreds of thousands of small segments of long-form streaming content -- is now eliminated.

Google, with its Android mobile operating system platform, has adopted HLS for Android OS 4. Some enterprising companies have even gone back and created HLS playback for earlier versions of Android OS-based devices.

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

From www.netview.no - January 17, 2012 6:51 PM

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

Streaming Video Technologies Panorama, part 2 : Server-Side Stream Repackaging

From blog.eltrovemo.com - July 19, 2011 7:46 PM

There are basically two ways to sustain the extensive growth of video formats that you must, as a media distributor, serve to your different clients’ target devices : the most common answer is to choose the best in breed most-powerful encoders to prepare all the target formats during the content preparation time (see Panorama article N°1 on this topic), but you can adopt a different approach saying that you want to prepare your contents once and have the distribution part of the overall workflow take care of the repackaging and protection of the contents on the fly.

Server-side repackaging of the streams consists eventually in :
- choosing languages in audio and subtitle tracks available in the original mux (optional)
- transcoding/transrating the video content in different sizes/bitrates from a high quality video file (optional)
- applying a DRM compatible with the output format (optional)
- generating the manifest file corresponding to the target adaptive streaming technology (mandatory)
- remuxing and chunking the video data according to the output protocol requirements (mandatory)

Historically, repackaging was pushed as a quick solution for broadcasters to add iOS streams on top of existing Smooth or Flash streams. In a wider OTT/Adaptive Bitrate perspective, this alternative approach means : less files to manage in the main production workflow, less storage, less bandwidth to populate the origin servers, smaller time to contents’ online availability and easier support for new formats – shortly said, an agile path.

Potentially a risky one, but quite attractive…

Let's examine the available options on the market, to do it on your own platform or in the cloud !
