With the rise of MPEG-DASH and the NAB-related announcements from both Microsoft and Adobe on the topic, we sat down with both companies to discuss the status of DASH support as well as their legacy ABR protocols, Smooth Streaming and HDS. In late 2012, Microsoft release the specification “DASH Content Protection using Microsoft PlayReady,” which explained how to use PlayReady with Common Encryption and MPEG-DASH. In June 2013, Windows Azure Media Servicesadded the support for MPEG-DASH as a new Dynamic Packaging output. At IBC 2013, Microsoft officially announced a new PlayReady version supporting HTML5, Encrypted Media Extensions, as well as new SDKs for iOS and Android. Their recent NAB 2014 announcements show how much work has been done under the hood to support DASH on the maximum number of platforms. We put a few questions to the Windows Azure Media Services team—namely senior digital media architect Kilroy Hughes, principal program manager lead John Deutscher, program manager for dynamic packaging Nick Drouin and program manager for client SDKs Cenk Dingiloglu. Here’s what they told us.

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.

DVEO, the broadcast division of Computer Modules, Inc. (CMI), is now shipping their new continuous streamer and VOD (video-on-demand) media server. The Infinity Streamer™ streams multiple HLS video files, plus audio files, from the on board .5 TB drive, with scheduled playlists. DVEO will demonstrate the new system at the International Broadcasting Convention (IBC) in Amsterdam, September 7-11, at Stand 2.A54. The Infinity Streamer is a streaming server for stored content. Input can be individual files or multiple files. File types supported are H.264 ts, flv, H.264 ps, .mov, VC-1 (.wmv), mkv, and others. The Infinity Streamer also supports loopable playback. The system has been tested to be compatible with the latest Adobe®, Wowza®, and Real Helix™ servers, and many CDNs.

The term adaptive streaming refers to technologies that encode multiple instances of a live or on-demand stream and switch adaptively among those streams to deliver the optimal experience to each viewer, taking into account both delivery bandwidth and playback horsepower. Producing for adaptive streaming involves two discrete analyses: how to choose the optimal number of streams and their configurations and how to customize the encoding parameters of the various streams to operate within each adaptive streaming technology. This article will explore both analyses.

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 !

Bridge Technologies has launched PocketProbe, an iPhone app that enables objective analysis of real network performance of streaming media, in a simple to use, easy to understand tool that technical staff can carry anywhere. PocketProbe contains the same OTT Engine found in the company’s VB1, VB2 and 10G VB3 series digital media monitoring probes, enabling confidence validation and analysis of http variable bit-rate streams from any location.
PocketProbe is available in two versions: the free application can validate five HLS streams in round-robin mode, provide analysis and manifest consistency alarms, play back media in the various profile bit-rates, and graphically display the actual chunk download patterns and bit-rates. The full version also offers the ability to validate HDS and SmoothStream manifest files and store twenty-five streams with all profiles.

The actual OTT market uses Adaptive Bit Rate video format over HTTP (Smooth Streaming, HTTP Dynamic Streaming, HTTP Live Streaming and MPEG-DASH soon) to deliver the content. Although it excludes the DRMs system which is a big topic in itself, here is an overview of the different formats available for each platform and of the different solutions (self-hosted, CDN, Cloud) to handle it.
