The new frontiers of OTT delivery: Multicast, P2P & Hybrid

The new frontiers of OTT delivery: Multicast, P2P & Hybrid | Video Breakthroughs | Scoop.it

4K streaming, mobile broadcasting for the crowd, generalized delinearization, worldwide video events…


OTT delivery is just multiplying the challenges, as customers’ expectations are raising each day in terms of video fast-start, instant channel switching, lack of buffer and high frame size/rate – on all devices in all network conditions. To answer those challenges, OTT delivery answer today is basically more unicast sessions, more servers, more peering – and less and less guarantee of satisfying end-user experience as long as there is no specific end-to-end paid agreement to guarantee that the path will be provisioned from the origin server up to the video device. Even in this ideal scheme, the device might still suffer from poor wireless conditions which jeopardize the experience. So, how do we deal with all this stack of potential problems: do we stick to the aging receipts, rely blindly on Moore’s law and perpetuate a hopeless CDN weapons race? Or do we try to find smarter ways to make the OTT growth reach a sustainable delivery model ?

nanoCDN could change live multi-screen economics

nanoCDN could change live multi-screen economics | Video Breakthroughs | Scoop.it

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.

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

Les nouvelles frontières de la diffusion OTT : Multicast & P2P [Conférence OVFSquad] | Video Breakthroughs | 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.
