Live streaming every phase of every sporting event of the Olympics is a big task. This year NBC expanded their targeted devices to include iOS, Android and Windows smartphones, PCs, Macs, and tablets. The combination of the increased number of live feeds and the increased number of targeted devices creates a complex live video workflow requiring coordination between a number of technologies and partners.
Nicolas Weil's insight:
If you look for me : I'm on point 6 :-)

Broadpeak’s nanoCDN solution will be launched commercially early this year, giving telcos and cable operators the opportunity to reduce bandwidth consumption and simultaneously increase the QoE for customers watching live streaming video on multiscreen devices. This product has the potential to change the economics of streaming but until now there have been only limited details available about how it works and what it can achieve. Broadpeak has just started releasing more details.

Minimizing Server Throughput for Low-Delay Live Streaming in Content Delivery Networks (F. Zhou, S. Ahmad, E. Buyukkaya,R. Hamzaoui and G.Simon)

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.

Broadpeak, a leading provider of content delivery networks (CDN) and video-on-demand (VOD) servers for cable, IPTV, OTT, and hybrid TV operators worldwide, today launched nanoCDN, a revolutionary CDN technology that leverages home networks to dramatically reduce infrastructure investments for operators and enable them to more efficiently deliver high-quality video services to end users. The first application of nanoCDN will be used for live OTT video delivery, with more applications to be supported in the future. Broadpeak will showcase nanoCDN for the first time at IBC2012 in Amsterdam.
nanoCDN improves the scalability of live OTT TV content by effectively managing video consumption peaks that are not supported by the network infrastructure. Utilizing nanoCDN, cable and telecom operators can cost-effectively deliver high-quality, live OTT video services to millions of simultaneous viewers using only a few megabits per second from the operator network. nanoCDN can seamlessly be integrated with any existing video headend. Completely transparent to end users, the cost-effective solution does not require a dedicated client and is compatible with any DRM system.

Jacques Le Mancq (CEO) m'a confirmé aujourd'hui qu'il n'y a aucune technologie P2P utilisée dans la version actuelle, c'est bien du multicasting. Je pense que l'avantage principal de cette solution par rapport à du caching traditionnel de flux live est qu'elle nécessite beaucoup moins d'investissement en hardware/management (les X niveaux de caches à setuper et à gérer/scaler) puisque mettant à contribution les gateways. Inversement c'est aussi un désavantage puisqu'il faut upgrader les gateways, ce qui peut être long et laborieux, surtout si plusieurs générations de en sont déployées. Mais le client nanoCDN étant royaltee-free, le jeu de transformer la GW en relai CDN en vaut certainement la chandelle d'un point de vue économique...

Bon et bien mon intuition était fausse :)
Merci pour cette recherche approfondie très intéressante. Donc on retombe sur ce que tu disais au départ uniquement "live", VOD trop compliquée.

Infos complémentaires sur le transparent caching (http://goo.gl/fvRzr) dans les commentaires : le prix des équipements est élevé (il est souvent plus économique d'acheter plus de peering vers L3), et surtout un argument de choc dans le dernier commentaire... "This (transparent caching) doesn't address the last mile which is the real bottleneck for cable, DSL, and wireless (all flavors including satellite) customers."
