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.

QoE evaluation for video streaming over eMBMS

QoE evaluation for video streaming over eMBMS | Video Breakthroughs | Scoop.it

As the multicast standard for Long Term Evolution (LTE), Enhanced Multimedia Broadcast Multicast Service (eMBMS) was introduced by Third Generation Partnership Project (3GPP) to facilitate delivery of popular content to multiple users over a cellular network. If a large number of users is interested in the same content, for e.g., live sports, news clips, etc., multicast transmission can significantly lower the cost and make better use of the spectrum as compared to unicast transmission.


In this paper, we study and analyze the quality of experience (QoE) at the end user during live video streaming over eMBMS. We consider a comprehensive end-to-end MBMS streaming frame-work based on H.264/AVC encoded video content delivered in a chunked format over multiple segments using the File Delivery over Unidirectional Transport (FLUTE) protocol, combined with application layer (AL) forward error correction (FEC) based on Raptor and RaptorQ codes. Specifically, our study involves QoE evaluation in terms of startup delay, rebuffering percentage and Peak Signal-to-Noise Ratio (PSNR) metrics and provides performance evaluations to characterize the impact of various MBMS streaming, transport and AL-FEC configurations on the end user QoE. We also propose a decoding strategy that takes into consideration the systematic structure of AL-FEC codes to enhance performance when a source block decoding fails.

Expway eMBMS (DASH compliant) Solution Allows Mobile Operators to off-Load Mobile Traffic by 20% [PR]

Expway eMBMS (DASH compliant) Solution Allows Mobile Operators to off-Load Mobile Traffic by 20% [PR] | Video Breakthroughs | Scoop.it

Expway has announced the launch of the 5th generation of its Mobile Broadcast software, the eMBMS solution, at the Mobile World Congress 2013. The solution enables Mobile Operators to broadcast any content, live or on-demand, over their LTE network.

 

About the eMBMS Solution :

 

The eMBMS Device Middleware controls the eMBMS LTE modem, receives and decodes the eMBMS streams. It stores or displays the received content through a separate Video Player.

 

The eMBMS DASH Video Player resides next to the Middleware and is used to play all unicast and broadcast video streams compatible with the newly adopted DASH standard. It uses devices hardware acceleration for best performance.

 

The eMBMS BM-SC Server handles the service layer at the eMBMS network, allowing the Carrier to push files and delivers live TV streams, on its LTE network, by using broadcast.
