Video Breakthroughs

Comme de coutume chaque mi-septembre depuis 2010, direction Amsterdam pour l’IBC, le plus grand salon de la télévision numérique avec le NAB de Las Vegas qui a lieu en avril. On y trouve de tout, des outils de captation, de production, de diffusion et de réception. Avec plus de 1700 exposants, on y découvre la floraison de sociétés qui se disputent un marché en perpétuel renouvèlement. Ce salon a lieu juste après l’IFA de Berlin qui est destiné aux produits grand public et auquel je ne me rends pas, réservant ce domaine au CES de Las Vegas en janvier.

Sans grande surprise, les mots clés de ce salon étaient : OTT multi-écrans s’appuyant sur des architectures en cloud et l’adoption massive de la 4K/Ultra HD par les industriels du broadcast.

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.

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.

This blog gives an overview of what kind of client support Microsoft offers as part of Windows Azure media Services. On one side, you could create, manage, package and deliver media asset through Windows Azure media services. Many popular streaming formats are supported, such as Smooth Streaming, Http Llive Streaming and MPEG-dash. On the other hand, we provide various SDKs and frameworks for you to consume media asset by building rich media applications rapidly on many platforms, such as PC, XBox, mobile and etc.

Cloud-based streaming and production services can be a boon to any large broadcaster, providing scale, power, and features inaccessible from on-premises facilities with minimal capital expenditure (CAPEX) and maintenance expenditures. Microsoft’s IIS Media Services, long a staple in on-premises servers of many broadcasters and large enterprises, has migrated to the cloud and is now available as Windows Azure Media Services. In this article, I’ll discuss the features of the service, how it was proven during the 2012 London Olympics, and the benefits achieved by two early adopters, NBCUniversal and the European Tour (a golf event).

Geneva in late March doesn’t feel as wild as a Las Vegas boulevard, but still there was a reasonable amount of gaming excitement at the EBU headquarters, where several events were following each other, beginning with a DASH Interoperability Forum meeting which was closely followed by the BroadThinking event, where industry actors and broadcasters come to show off their latest implementations advances and/or share the results of their real-life deployments or research studies. A good way of managing the transition between TV Connect and NAB…

Where Broadcast meets Broadband : that’s the promise of the EBU’s hybrid event which flies between industry competition, standardization efforts and broadcasters’ realpolitik – all wrapped in a warm and funny ambiance provided by the various speakers and the EBU team gently lead by Bram Tullemans whom I’d like to thanks personnally here for the presentation invitation (kudos also to Filka, Peter and Eoghan for the organization!). Actually the 2013 edition was a major success because it allowed the participants to get a rather good idea of the general trends of the industry, and at the same time to go deep in technology when needed, while having opportunities to discover edge tech demos on the lobby attending the conference room.

It’s virtually impossible to render a complete report of everything that has been said or shown there during two days by so many quality speakers (including OnlineVideoFrenchSquad group distinguished members Lionel Bringuier [Elemental Technologies], Martin Boronski [M6 Web], Thierry Fautier [Harmonic] and Nicolas Weil[Challenge2Media] – Les 4 Mousquetaires /poke @sfaure  ), but I’ll nevertheless try to provide you here a selection of relevant informations that will help you grasp the trends and prepare the upcoming tradeshows efficiently…

So let’s start with DAY 1 recap !

This year the EBU BroadThinking Conference was sounding like a holistic swirl, a milestone in the trend of technology to define sets that are greater than the sum of their parts, through creative evolution. « Where Broadcast Meets BroadBand », you get some interesting fusion effect occurring and diluting the traditional boundaries of the screens, with the handheld devices being part of the big screen experience or extending it rather than trying to scalp it, in an environment where all the devices converge towards a restricted set of standards rather than tracing their own line.

While we by default think that standardization kills creativity, events like BroadThinking show that it’s the opposite: if we gather energies to solve common problems together, we can both come up with a more evolved solution and concentrate on what’s important past the pixel grid: the user experience, so consistent across screens that you forget there’s more than one screen involved.

For the last two years, I have been working to extend the capabilities to of the Origin Server for Window Azure Media Services. In January of 2013, Windows Azure Media Services (WAMS) became generally available as a Platform as a Service (PaaS) on Windows Azure, Microsoft’s cloud computing platform. Just over a year later, it would stream the largest live sporting event in history – millions of concurrent users and over 10,000 hours of unique content over the 16-day Sochi Winter Olympic Games. This article describes the capabilities of Microsoft’s origin server, as well as the evolution of the product in the last two years to meet today’s demanding streaming media space.

ACCESS has been presenting a vision of how Pay TV operators can start to marry their broadcast/VOD infrastructure with multiscreen/OTT delivery infrastructure and treat them as a shared resource to optimize the delivery of content to multiple devices around the home, including televisions. It uses its Netfront Living Connect DLNA stack and client software to provide a central view of what each device is capable of and what is currently happening on that device to then manage whole-home resources.

Content can be distributed using the new DLNA Commercial Video Profile-2 (CVP-2), which was developed with the cooperation of service providers to enable more secure playback of their content across multiscreen devices. It also gives them more control over the user interface on different devices. CVP-2 leverages HTML5 Remote User Interfaces (RUIs) and HTTP Adaptive Delivery and Authentication on top of the DTCP-IP-based link layer protection, which was already available. ACCESS is actually demonstrating NetFront Living Connect with CVP-2 at the DLNA Members meeting in Hawaii today (Thursday October 10).

In this new architecture, DLNA acts as an abstraction layer. Not only does it provide a unified view of activity across diverse devices, it also means platform operators can avoid writing native apps for each DLNA-enabled device. You still need a software client to reach them but not the unique applications development work. “DLNA is a way to overcome device fragmentation,” says Larbey at Alcatel-Lucent.

Nothing was more welcome after day 1 of EBU BroadThinking 2013 than a good night of sleep, in order to reset the tech hype counters and make some mental room for two new sessions on broadcasters’ CDNs and the latest advances of hybrid platforms. What would be the best broadcasters’ CDN architectures today, what would be their smartest (green) evolutions, would CDN-Federation standards finally bring interop reality over hopes, what would be the most advanced deployments and future of HbbTV, how it compares with YouView in the UK : day 2 agenda was looking quite attractive – and indeed the presentations were packed with valuable informations and experience feedbacks.

So here is the recap of the most interesting DAY 2 presentations and a short report on some insightful demos that were playing on the EBU floor right to the conference.

In our previous posts about Netflix personalization, we highlighted the importance of using both data and algorithms to create the best possible experience for Netflix members. We also talked about the importance of enriching the interaction and engaging the user with the recommendation system. Today we're exploring another important piece of the puzzle: how to create a software architecture that can deliver this experience and support rapid innovation. Coming up with a software architecture that handles large volumes of existing data, is responsive to user interactions, and makes it easy to experiment with new recommendation approaches is not a trivial task. In this post we will describe how we address some of these challenges at Netflix.
