Broadcast over LTE

Introduction

What is LTE Broadcast?

How could LTE broadcast be used?

Advantages

Summary


3/11


BBC Interest BBC has fantastic content

Trying to get to as many viewers as possible

Recently announced renewed focus on Live Events

BBC has always been an innovator

BBC R&D is at forefront of innovations We are exploring Broadcast over LTE


4/11


Background Mobile TV propositions emerging

Mobile unicast streaming

has its limitations

Capacity constraints buffering

Data caps

Issue for video but also radio

Listening works when walking

Broadcasting is efficient

and can offer consistent QoS


5/11


LTE can support broadcasting

eMBMS (LTE Broadcast)

Allocate parts of the LTE signal over to broadcast

One-to-many distribution

Option of Single Frequency Network support

Already standardised by 3GPP Worldwide standard

Doesnt require a separate receiving chip in handset

How it works

LTE Multiple unicast streams to

each handset within a cell

eMBMS Single multicast stream to

every handset within a cell

eMBMS (MBSFN) Single multicast stream to

every handset across multiple

cells



How could it be implemented?

Hybrid and dynamic network Deploy in congested areas; enable for peak demand

content

In-band no spectrum sharing

single receiver

Out-of-band

Potentially more efficient

not yet standardised

LTE Broadcast advantages Why LTE Broadcast/eMBMS?

The time is right Capable devices

Consumers becoming familiar with mobile video

Olympics has raised expectations

Significant untapped demandespecially linear/live eMBMS part of 3GPP standard

Chipset support

Towards universal implementation?

Network can be dynamically adapted according to demand

For example, at big sports/entertainment events

Potentially much more spectrally efficient than unicast

BBC content reaches more viewers more often



Summary BBC produces fantastic content

Video, radio and online

We are always keen to find new ways to reach our

audience

LTE supports broadcastingeMBMS Works by allocating parts of an LTE signal to the

broadcast mode

Could be deployed as a hybrid, dynamic network

Doesnt require another receiver chip in handset

BBC R&D is currently exploring this opportunity



Thank you for listening
