A new hybrid mobile broadcast technology platform could provide a solution to the current standoff between the mobile and TV sectors over a common approach to mobile broadcast standards. The system, which embeds an LTE-A+ video steam within a standard DVB-T2 broadcast signal, is about to be field-trialled.

![Les nouvelles frontières de la diffusion OTT : Multicast & P2P [Conférence OVFSquad] | Video Breakthroughs | Scoop.it](https://img.scoop.it/pOujM-JuMKqsNZVy_hdtAjl72eJkfbmt4t8yenImKBVvK0kTmF0xjctABnaLJIm9)
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.

MPEG-DASH is slowly but surely becoming the main competitor to HLS, driven by adoption by major players and intrinsic strengths. Here's who's using it now, who's going to be soon, and what challenges still need to be addressed.
Last year at the European Broadasting Union’s BroadThinking conference, the DASH Industry Forum (DASH-IF) conducted a survey of 13 major European broadcasters on MPEG-DASH adoption. At the time, about three-quarters of them projected to have DASH deployed by end of first half of 2014. Primary sources of concern for the broadcasters were the availability of DASH enabled clients and packaging tools. One year later, we haven’t seen many broadcasters deploying DASH in production, but the traction seems to have shifted to over-the-top (OTT) content distributors and operators.
So, who are the actors already in production or close to production with DASH? What are the remaining roadblocks for its adoption? How will DASH be positioned against existing Adaptive Bitrate technologies in the coming months? What is the exact status of the DASH standard and its most promising evolutions? What are the upcoming initiatives aiming at fostering DASH adoption? Let’s get a handle on where DASH is today, and where it’s headed. Via DASH Industry Forum

Everybody (or nearly) is DASH compliant but when you really want to have it running, it is not exactly as smooth as expected. Still, it seems to be really starting this time.

By multicasting popular content over cellular networks, carriers figure they can conserve valuable 4G capacity. But as consumers use their smartphones and tablets to personalize their multimedia consumption, the ship may have already sailed on multicast’s potential.
