What are the consequences

for the future delivery of

broadcast content?



Dr. Roland Beutler

Observations


• Linear audio-visual content will remain the killer application for the foreseeable future.


Dr. Roland Beutler

Observations



• However, there is an increasing demand for nonlinear content which may not be possible to deliver by broadcasting technology.


Dr. Roland Beutler

Observations




• Portable and handheld devices (smartphones and tablets) are key for the future development of terrestrial broadcasting.


Dr. Roland Beutler

Observations





• The only distribution technology to target these devices is a terrestrial platform.

Observations





• The only distribution technology to target these devices is a terrestrial platform.

• Terrestrial broadcasting and wireless broadband are complementary delivery mechanisms.


Dr. Roland Beutler



Terrestrial Broadcasting Wireless Broadband

• universal coverage• any reception mode• guaranteed, predictable quality• cost-efficient delivery to large audiences

(independent of the number of simultaneous users)

• every user has access to the total capacity of the network

• bi-directional• designed for mobile reception• potentially unlimited choice of services• well suited to serve small audiences• growing population of user equipment• IP-based

• one-way, no return channel• the offer is limited by the platform capacity

(no niche channels)• limited delivery to mobile devices• no access to IP-only devices

• limited coverage (where quality is sufficient)• only best effort QoS• high costs, depending on the number of

users; not suitable for large audiences• total capacity is shared between users

EBU Recommendations for Members



EBU – Recommendation R 136

Spectrum Requirements for Broadcasting Services in preparation for WRC-15

GenevaJune 2012

tech.ebu.ch

Dr. Roland Beutler




1. The EBU and its Members emphasize to the national, European and International authorities, the importance and the diversity of terrestrial broadcasting markets and services;

Dr. Roland Beutler





2. The frequency band 470 – 790 MHz should be retained for the delivery of broadcasting services (both linear and non linear), taking into account future service and technology developments. This would provide certainty to broadcasters and the industry alike, and encourage further standardisation work and investments;

This would provide certainty to broadcasters and the industry alike, and encourage further standardisation work and investments;

3. The EBU and its Members work to ensure close integration between the linear and non-linear services they deliver to mobile devices, PCs, tablets and hybrid television sets. This includes requiring the use of the 470 – 790 MHz band for these services.

Dr. Roland Beutler

… and for regulators



• Develop a vision of the future audio-visual media ecosystem including economic, political and social implications.

Dr. Roland Beutler





• Do not preempt future developments by means of irreversible decisions taken in a rush.

Dr. Roland Beutler





• Do not preempt future developments by means of irreversible decisions taken in a rush.

• Enable spectrum sharing between the broadcast and the mobile service in your regulation.

Broadband Initiatives



Dr. Roland Beutler


Australia

National Broadband Network

• Idea: connecting all premises to a new high-speed broadband network

• Time frame: 2020

• Coverage target: 93% of homes, schools, business via fibre to the

premises at up to 1 Gbps 7% by fixed wireless & satellite at up to 12 Mbps

• Driver: newly founded Government company (NBN Co Limited)

• Access and usage sold to service providers (ISPs)


Dr. Roland Beutler


Europe

Digital Agenda 2020

• Idea: broadband access to all European citizens

• Time frame: 2020

• Coverage target: 30 Mbps for 100 % of citizens 100 Mbps for 50 % of citizens

• Method: any suitable broadband platform

• Driver: market forces


Dr. Roland Beutler

Networks 2.0



Dr. Roland Beutler

Terrestrial Networks:

Best of Both Worlds



Dr. Roland Beutler

Terrestrial Convergence


• Consumption on portable / mobile devices is key

• High quality for these devices

• Return channel has to be enabled

• Options for future system development: DVB-Tx bidirectional? LTE-Advanced+ incl. broadcast mode?

• Convergence of terrestrial networks: adaption of content quality dynamically reconfigurable between unicast,

multicast & broadcast mode

• Driver: market forces

Just Fiction?


Dr. Roland Beutler


Just Fiction?

• „Broadband To All – An Alternative Vision Report“ UK Government report published 31 July 2012

139: “It is likely that IPTV services will become ever more widespread, and eventually the case for transferring the carriage of broadcast content, including public service broadcasting, from spectrum to the internet altogetherwill become overwhelming. This may well be a more sensible arrangement, as spectrum is perfectly suited tomobile applications. … Most people watch their television in fixed locations from fixed sets. Actually, spectrum’sgreat wonder is its ability for mobility.”

140: “As such, it might be argued that spectrum’s current use for fixed, broadcast purposes is wasteful.”

141: “We recommend that the Government, Ofcom and the industry begin to consider the desirability of the transfer of terrestrial broadcast content from spectrum to the internet and the consequent switching off of broadcast transmission over spectrum, and in particular what the consequences of this might be and how we ought to begin to prepare.

Just Fiction?

• IRT Studies on WLAN 802.11aco up to 600 Mbps for line of sight

o if there are brick walls data rate drops to 100 Mbps

• Converter from satellite to IP are available

o satellite penetration in Germany about 40%

Inhome HD distribution to any IP-enabled device (fixed, portable or handheld) is possible !!!

New distribution concept: Pick-up and re-distribute


Dr. Roland Beutler

Forecasting:

Where Do We Go?



Dr. Roland Beutler


Basic Questions

• What will the future terrestrial distribution platform look like?

• When will there be a universal broadband backbone network?

• Who will invest in these networks and who will operate them?

• Will there be shared infrastructure?

• What will the technical/regulatory framework look like?
