Video Breakthroughs

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 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.
