Introducing: Azure Media Indexer

Introducing: Azure Media Indexer | Veille & Prospective - Audiovisuel | Scoop.it

The Internet was designed around text-based documents, and as such, has mature infrastructure to encourage and enable the search and discovery of text across the entire web. Video files, on the other hand, are not natively “searchable”, and usually require complex classification systems primarily powered by massive amounts of manually-tagged metadata. But what if there was a way to extract this kind of meaningful metadata automatically? Azure Media Indexer is a media processor that leverages natural language processing (NLP) technology from Microsoft Research to make media files and content searchable by exposing this meaningful metadata to the end-user automatically in the form of a keyword file (XML), a set of closed caption files (SAMI/TTML), and a powerful binary index file (AIB).

Elemental Technologies demonstrates End-to-end 4K HEVC workflow at the 2014 Winter Games | Veille & Prospective - Audiovisuel | Scoop.it

NTV Plus pioneered the initiative to broadcast the Sochi 2014 Winter Games in 4K. Following an extensive period of testing during 2013, NTV Plus designed and deployed an end-to-end 4K HEVC workflow that features Sony 4K cameras, Elemental Live video encoders, NTV Plus satellite uplink and signal receiving systems and Broadcom-enabled real-time decoders for playback on Panasonic 4K TVs. A single video stream encoded by Elemental enables NTV Plus to reduce the 100Mb of bandwidth which would otherwise have been required for delivery of 4K HEVC content.

Akamai gives new clues to the future of Internet video delivery

Akamai gives new clues to the future of Internet video delivery | Veille & Prospective - Audiovisuel | Scoop.it

Akamai has been providing a number of clues about how the company intends to dramatically increase the performance of the Internet for video streaming to support Ultra HD and ultimately match the scale and quality of broadcast TV. One big clue could be found on the Qualcomm stand at International CES 2014 when that company’s subsidiary, Qualcomm Atheros, was demonstrating its IPQ home gateway. Among other things this included a proof-of-concept client software from Akamai that is designed to optimize the delivery and pre-positioning of content like video and software.

 

The client software is not a product yet but Akamai is certainly talking as if it will be. Kris Alexander, Chief Strategist, Connected Devices & Gaming at Akamai, says, “The demo offers a glimpse into the future of the Akamai platform as we explore ways to move beyond the edge and onto devices of many types – not only gateways but game consoles, set-top-boxes, Blu-ray players, connected TVs and more.”

Google’s VP9 Video Codec Gets Backing from ARM, Nvidia, Sony And Others, Gives 4K Video Streaming A Fighting Chance

Google’s VP9 Video Codec Gets Backing from ARM, Nvidia, Sony And Others, Gives 4K Video Streaming A Fighting Chance | Veille & Prospective - Audiovisuel | Scoop.it

Google’s VP9 video codec is getting a major boost today. While Mozilla, Google’s own Chrome browser and a few video players like FFmpeg started supporting VP9 over the course of the last year, what was mostly missing from Google’s ecosystem for this highly efficient video codec was hardware support. As Google announced today, however, virtually all major hardware vendors will soon support VP9 natively in their products and allow Google’s YouTube to stream HD content up to 4K directly to computers, TVs and mobile devices.

 

These new hardware partners include ARM, Broadcom, Intel, LG, Marvell, MediaTek, Nvidia, Panasonic, Philips, Qualcomm, RealTek, Samsung, Sigma, Sharp, Sony and Toshiba.

The Netflix Tech Blog: STAASH - STorage As A Service over Http - A multi-storage abstraction layer

The Netflix Tech Blog: STAASH - STorage As A Service over Http - A multi-storage abstraction layer | Veille & Prospective - Audiovisuel | Scoop.it

Netflix’s Astyanax project, and the recipes contained therein, have been a tremendous tool in helping Java developers adopt Apache Cassandra (C*), both within Netflix and outside of Netflix.  A common request we have gotten from non-Java, or non-JVM based (eg: Python, Ruby, BASH, JavaScript), developers is that they would like to take advantage of the recipes provided in Astyanax such as All-Rows-Query or Chunked-Object-Store.

 

STAASH’s short-term goal is to recreate the most popular Astyanax recipes as a service, providing a REST based API to Cassandra. This would allow ANY language to consume those recipes.

La complexité des DRM dans un contexte OTT

La complexité des DRM dans un contexte OTT | Veille & Prospective - Audiovisuel | Scoop.it

J’ai assisté hier à plusieurs présentations au SATIS, dont la « Carte blanche OVFSquad – DRMs – quel prix pour la sécurité de l’OTT ? ».

La question est importante, car tous les distributeurs de contenus en OTT sont confrontés à l’implémentation des DRM imposées par les ayants droit (pour appuyer sur un fait exprimé par les intervenants, ce n’est pas de gaité de cœur que les sites de VOD mettent en place des DRM ; s’ils ne le font pas, ils n’ont pas les films, point !).

 

Quelques rappels tout d’abord :

-          OTT (Over The Top) veut dire en pratique diffusion en dehors des plateformes IPTV des FAI, donc directement sur Internet; cela s’applique en particulier à la VOD (Vidéo à la Demande) sur PC, Mac, tablettes et TV connectées.

-          DRM (Digital Rights Management ou gestion de droits numériques) correspond à la protection du contenu par un système de licence (qui limite l’utilisation du contenu à certaines plages de temps, certains pays, certains terminaux) et un système de chiffrement des contenus (qui évite une utilisation immodérée du contenu).

-          ABR (Adaptive Bitrate) correspond à des technologies de streaming qui permettent d’adapter la qualité d’image d’un flux vidéo à la bande passante disponible. L’idée est de préférer une  image de moins haute définition à  une image qui bloque (freeze) de temps en temps.

 

Le problème est d’autant plus complexe le nombre de terminaux supportés est important. Supposons que vous développiez une plateforme VOD premium, qui commercialise des long-métrages pour lesquels l’implémentation d’un système de DRM est imposée, et qui désire mettre en place une diffusion ABR. Supporter PC et Mac est relativement facile, quoi que …

Key Media Industry Organizations Launch Joint Task Force on File Formats and Media Interoperability

Key Media Industry Organizations Launch Joint Task Force on File Formats and Media Interoperability | Veille & Prospective - Audiovisuel | Scoop.it

The launch of the Joint Task Force on File Formats and Media Interoperability was announced today by its sponsors, the North American Broadcasters Association (NABA), Advanced Media Workflow Association (AMWA), Society of Motion Picture and Television Engineers (SMPTE), International Association of Broadcast Manufacturers (IABM), American Association of Advertising Agencies (4A’s), and Association of National Advertisers (ANA). The European Broadcasting Union (EBU) is participating as an observer.

 

Bringing together manufacturers, broadcasters, advertisers, ad agencies, and industry organizations (standards bodies and trade associations) serving the professional media market, the Task Force has an ultimate goal to create greater efficiencies and cost savings for exchange of file-based content. The group’s initial focus will be to gather and analyze requirements for a machine-generated and readable file interchange and delivery specification — including standardized and common structured metadata — for the professional media industry. Use case examples include promo, spot, and program delivery from a provider to a broadcaster.

Les nouvelles frontières de la diffusion OTT : Multicast & P2P [Conférence OVFSquad]

Les nouvelles frontières de la diffusion OTT : Multicast & P2P [Conférence OVFSquad] | Veille & Prospective - Audiovisuel | Scoop.it

Avec le passage au full HD et bientôt à la 4K de a diffusion OTT, le modèle de distribution unicast montre ses limites. La course à l’armement des CDNs dans le déploiement de baies de serveurs et la multiplication des points de peering n’est pas scalable à l’infini, et pourtant le traffic vidéo ne cesse d’augmenter de manière exponentielle, y compris – et surtout – sur les terminaux mobiles. La recherche de modèles de distribution OTT complémentaires avec le multicast est donc une priorité pour continuer d’assurer la qualité de l’expérience utilisateur et optimiser les coûts de diffusion. Les regards se tournent de plus en plus vers le transport multicast qui a fait le succès de l’IPTV, ainsi que le Peer-to-Peer qui, malgré sa réputation sulfureuse, a déjà fait ses preuves pour la diffusion de chaines live OTT à très grande échelle.

 

Pour tout savoir du multicast et du P2P, et apprendre des retours d’expérience et de recherche des membres de la Squad qui travaillent sur ces systèmes hybrides, OVFSquad organisait le 23 janvier 2014 une soirée spéciale de présentations (aka « Conférensquad ») dont voici le compte-rendu et les présentations.

A Potential 4K Problem?

A Potential 4K Problem? | Veille & Prospective - Audiovisuel | Scoop.it

John Batter, CEO of M-Go, the transactional VOD content service backed by DreamWorks Animation and Technicolor, had every reason to smile at the International Consumer Electronics Show (CES).

 

Standing in front of a 4K TV at the sprawling Samsung booth, Batter showed off an upgraded, more user-friendly interface for M-Go, which had just announced a new 4K streaming service exclusively through Samsung.

 

“We think it’s really visually [unique],” he said of the 4K service, which will offer a combination of native 4K and up-scaled 4K movies, from Fox, Paramount and other studios. “Our plan is to build it up aggressively. We’ve got discussions going on with everyone right now.”

 

He went on to mention that content that’s merely optimized for 4K — which denotes a video resolution of 3,840 x 2,160 pixels, or four times that of current high-def — would only require a 3 Mbps Internet connection, an easy entryway for early consumers of 4K technology.

 

However, for native 4K, a 15 Mbps connection would be required for streaming purposes, Batter mentioned. And that portends a major problem for 4K overall, according to Dan Rayburn, principal analyst with consulting firm Frost & Sullivan, and EVP of StreamingMedia.com. Despite all the High Efficiency Video Coding (HEVC) compression solutions for 4K offered by numerous companies, despite the hardware push for 4K two years running now at CES, and despite the numerous 4K services announced at the 2014 CES — from Netflix, Amazon, Comcast and more — the content delivery model doesn’t make fiscal sense, in Rayburn’s estimation.

MPEG-DASH Conformance versus Client Performance : how to double your effective media stream bitrates

MPEG-DASH Conformance versus Client Performance : how to double your effective media stream bitrates | Veille & Prospective - Audiovisuel | Scoop.it

MPEG DASH was created to deal with a highly fragmented media streaming ecosystem struggling with fragmentation and lack of interoperability of many proprietary solutions. Still that fragmentation has not stopped video to grow to being over half of mobile, and almost three-quarters of fixed traffic (YE2012). But this situation very negatively impacts on the one hand technology scale and cost advantages in the industry, and on the other hand the end user experience, engagement and (advertising) revenues that keep the media wheel spinning.

 

Enter MPEG DASH - the industry-defined open standard for media streaming that has gained strong industry support. Many suppliers have announced support for MPEG DASH though broad, real-world deployment is still a few years out.

MPEG-DASH Ecosystem Status

MPEG-DASH Ecosystem Status | Veille & Prospective - Audiovisuel | Scoop.it

How dynamic is MPEG-DASH Ecosystem after IBC 2013 ? Here is an analysis of the latest trends and an extensive industry DASH-compliant solutions directory.

 

While most of IBC’s buzz was generated by the shiny HEVC + 4K couple, it was a good occasion to stand back from the hype and measure how one of the most important video standards (at least for the OTT world) had spread over the industry since last year. MPEG-DASH is not sexy (let’s remember that it’s basically a collection of XML schemes), it’s a bit boring (as it’s usually demonstrated with the Big Buck Bunny that you saw not less than 2.000 times) and it’s complex – but once you go past those defaults, you might find that its potential to simplify your workflows and boost the profitability of your video service is high…

And that’s precisely what the industry has finally understood: video distributors want to streamline their workflows and save their storage budgets by reducing the number of output formats, they search for ways to build long term strategies with evolutive solutions – and all of this implies rolling away from proprietary ABR solutions like Smooth Streaming, HLS, HDS and the now defunct Widevine WVM proprietary packaging format (rest in peace), DASH’s first victim.
