1 EBU strategy for broadcast/telecommunications convergence
Franc Kozamernik European Broadcasting Union

2 Agenda EBU in the nutshell Broadcast vs. telecom
Possible synergies of broadcasting, telecommunications and internet Possible scenarios Conclusions

3 European Broadcasting Union - EBU
The EBU is the largest professional association of national broadcasters in the world Founded in Merged with OIRT in 1993. 69 active members in Europe, North Africa and Middle East and further 45 associate members Eurovision and Euroradio satellite/terrestrial networks Programming, legal and technical activities

4 Broadcasting vs. Telecoms
Both broadcasting and telecommunications are important industries and both are playing their respective role in our societies. Both are mature industries and both have been highly successful, since several decades, in terms of building up a large consumer base, huge turnouts, large numbers of radio/TV receivers and telecom terminals used, extensive infrastructures large numbers of workers

5 Broadcasting vs. Telecoms
In the past, they have been evolving separately in different directions as two entirely different entities. Since last two decades, both industries made significant progress in adopting digital technologies. More recently, they embarked into packet-based technologies and the development of multimedia services and applications with the following common features: increased mobility, geographical and time independence, individualisation and personalisation, Interactive and on-demand services, better technical quality and increased security

6 Broadcasting vs. Telecoms
It is important to understand the differences between these separate industries Telecoms is mainly “one-to-one” Broadcasting is mainly “one-to-many” - All users tuned to a given channel receive the same content From the all-important perspective of users: Both models will continue to be needed for different types of services and applications Both models have advantages and disadvantages

7 Broadcasting vs. Telecoms
Economists designate free-to-air broadcasting as a “public good” because the marginal cost of extra viewers or listeners is zero Telecoms operators get more revenue as the use of their networks increases Broadcasters are mainly interested in content Delivery technologies are incidental to them Telecoms operators are mainly interested in delivery systems Content is incidental, but will become more important as the impetus for new services

9 Broadcasters Sound radio and television are the most important mass media and play a major and irreplaceable part in the lives of the people Radio is simple, ubiquitous, free service, non-expensive receivers, mobile and portable, user-friendly, informative and trusted medium Television is more sophisticated, used in the home/family, provides entertainment, information and education Both radio and TV are in the process of radical changes and move towards digitisation and multimedia

10 Content The choice of TV services available to the average consumer has increased dramatically, but expenditure on new programmes has not kept pace with this expansion Traditional broadcast services (i.e. one-to-many & one-way) will continue to be important because mass audiences are required to cover the costs of high quality content production Broadcasters will also embrace the opportunities offered by multimedia services and applications, including “interactive” and “on-demand” services Users will transform themselves from passive consumers to active creators able to choose the content and presentation to their liking

11 Broadcast Delivery Broadcasters (content providers) will probably become agnostic about delivery systems The existing analogue terrestrial transmissions will remain attractive because they are almost universally available Radio broadcasters can choose from: AM FM DAB (Digital Audio Broadcasting) Internet & its successors

12 TV Delivery Systems TV broadcasters will choose from:
analogue terrestrial analogue satellite digital satellite (DVB-S) digital terrestrial (DVB-T) digital cable (DVB-C) digital MMDS (DVB-MC & DVB-MS) Internet and its successors UMTS or GPRS broadband radio services (BRAN, MBS)

13 Digital Audio Broadcasting - DAB
Eureka 147 DAB system, first shown publicly in 1988 in Geneva Recommended by ITU-R as a a worldwide standard Terrestrial system using OFDM modulation, very robust, 1.5 Mbs channel, audio and data (multimedia) services 300 million people in 25 countries worldwide are within DAB reach Coverage in the UK is 79% of the population 509 different DAB services are available – 225 PSB, 284 CS 25 manufacturers are making 16 different types of consumer products – car, home, portable radios and PC cards Prices to fall by 50% or more (to £99) by end of 2001!

14 Digital Video Broadcasting - DVB
Family of DVB standards based on ISO MPEG-2 – Satellite, Cable, Terrestrial and MMDS De facto worldwide standard, flexible, robust, different bit rates and channels Multimedia Home Platform (MHP) paves the way to multimedia 7 million BSkyB and 1 million OnDigital set-top-boxes in the UK In UK, STB are given away for free – different business model than for DAB Terrestrial DVB is bogged down by the spectrum scarcity in Europe

15 EBU Statement on “DAB versus DVB-T”
DAB is to serve radio communities DVB-T is to serve television communities Similar technologies (OFDM) Different emphasis but complementary systems Both are needed and both should be deployed DVB-T cannot replace DAB, even not in a longer term DVB-T is able to carry radio services but this may represent only a minority market Both systems will be used for mobile Multimedia in future

16 Digital radio Mondiale - DRM
DRM is being developed to replace analogue LW, MF and SW radio below 30 MHz Designed as a flexible system able to overcome adverse propagation conditions – deep and long fades, echoes and multipath A variety of audio and channel coding options and modulation schemes to copy with different channel bandwidth requirements

17 Broadcasting to Mobile and Portable terminals

18 UMTS Stationary 2 Mb/s Pedestrian 384 kb/s Mobile 144 kb/s
Bit rate (kb/s)

19 UMTS and other radio technologies
DVB cable PSTN xDSL Stationary ISDN UMTS DVB satellite Pedestrian GPRS Mobile DVB terrestrial GSM DAB Bit rate (kb/s)

20 Analogue-to-digital transition
Digital technology must be significantly “better” in any respect than analogue radio for all players, especially for consumers An agreed introduction strategy and concerted/synchronous efforts of all major players at a national level public service and commercial broadcasters new content providers receiver/transmitter/IC manufacturers network operators spectrum regulators retailers users: customer awareness Public and governmental support is absolutely needed

21 A national matter Each and every country in Europe has very specific economic, cultural and media regulation situation Broadcasting (and electronic media) is a matter of national states or even regions (e.g. Germany) Any implementation plan and analogue switch-off strategy should take into account national broadcasting diversities and national priorities International organisations and associations such as EBU are valuable but cannot replace national efforts and decisions. They should however provide common technology standards, implementation guidelines, lobbying, promotion and advice

22 Governmental decision
Digital may take several years to reach the level of the present analogue broadcasting Transition to digital may be much slower than expected unless there is a concerted effort at a a national level Broadcasting will ultimately become digital, but at what stage the analogue stations may be withdrawn? As the transition is a costly exercise, small and commercial stations may remain on analogue for very long A governmental announcement of the analogue withdrawal deadline at an early stage would have a positive effect

23 Analogue Switch-Off A timely announcement of Analogue Switch-Off (ASO) by the national government will have the following advantages: A CLEAR SIGNAL TO ALL PLAYERS about the intentions of the government and will accelerate A-D transition NETWORK PROVIDERS - will reduce transmission cost which is now doubled due to simulcasting in analogue and digital. More money will be available for the completion of terrestrial networks ADMINISTRATIONS/REGULATORS - will be able to use parts of the analogue spectrum soon after ASO CUSTOMERS - will be encouraged to purchase digital STBs as of now MANUFACTURERS - will sell more digital products and the prices would go gradually down, diversity of receivers will increase

24 Interactive Multimedia Broadcasting
LEVEL 1: LOCAL INTERACTIVITY - storage in the terminal (e.g. TV Anytime) LEVEL 2: ONE-WAY RETURN CHANNEL LEVEL 3: TWO-WAY INTERACTIVE CHANNEL The answer to this question is unconditional and resounding YES. We will consider an example of the Multimedia Broadcasting system called MEMO: MEMO stands for: Multimedia Environment for Mobiles. MEMO is an ACTS project partly funded by the European Commission. The system is based on a combination of the high-speed broadcasting facilities of DAB or DVB-T for forward channel with a bi-directional telecommunication network such as GSM to provide an interactive channel. The MEMO system is an example of a asymmetrical broadcasting system: relatively broadc forward channel to allow for rapid downloading of large files or stream information, and relatively narrow capacity of the interactive channel to allow for the dialogue between the user and the source. All three system, in particular GSM, are European success stories. Three categories of services can be offered: a) Broadcast services b) Interactive broadcast, and c) Personal services This slide depicts Broadcast type services and virtual interactive services. The DAB (or DVB-T) down-link is used to mainly broadcast information of general interest (this is so called “push mode”). On the receiver side the information is filtered and stored in a local data base, consequently the interactivity is only virtual. *

25 LEVEL 1 Interactive Broadcasting
No return link needed Internal storage device in the user terminal to allow: linear programmes to be consumed in a non-linear manner (e.g. a news bulletin) users to “order” a programme to be recorded by a single click during a trailer intelligent agents to record programmes that they “think” you might want to listen to sophisticated interactive multimedia information services, continuously up-dated and available instantly to consumers automatic indexing of recorded programmes Examples: TV Anytime Project, TiVo

26 LEVEL 2 Interactive Broadcasting
Interactive Broadcasts can be further enhanced by the use of a narrow-band return channel (e.g. GSM, GPRS, UMTS, Internet) DAB or DVB-T can be used as forward transport media in connection with return channel Return channel connects the end user with the content originator: content provider service provider multiplex provider Supplementary individually addressed traffic Possibility for secure encryption or charging mechanisms

27 LEVEL 3 Interactive Broadcasting
LEVEL 3 allows for PERSONAL BROADCASTING DAB or DVB-T used as transport medium for broadcast and individually addressed traffic in connection with an interactive channel (e. g. PSTN, GSM, GPRS, UMTS, Internet) Highly assymetric services Requires roaming/handover network functionalities Requires secure encryption and charging mechanisms A WorldDAB project “DAB/Mobile” using SIM and Java card for transactions will start in the autumn Joint UMTS Forum / DVB Forum group (see TM 2466)

34 IP over broadcast channels
DAB and DVB broadcast channels have relatively large bandwidth but for regulatory reasons only a small portion (typically, less than 20%) can be used for data services such as IP multimedia Access to web pages via broadcast channels is fast and reliable Broadcasters may adopt a concept of a “Walled garden”: Pre-selection of Web pages limits the usefulness of this service compared with full Internet access. Broadcaster decides on a selection of “best” sites and transmits the same sites to all customers Customers can browse locally between the sites chosen by the broadcaster. Interaction channel is provided by a telecommunication channel

35 Push Technology Push technology is similar to broadcasting - “one to many” Multimedia files are pushed from a broadcaster as s to the subscriber computers (typically several hundreds only) different from broadcasting is that users can only receive their “narrowcast” information according to their individual “user profile” “Push” services delivered over the Internet allow users to specify their interests: news items about specific subjects, share prices for a particular company, etc. The user’s computer periodically checks if any relevant new information is available, and downloads it for display The number of subscribers could increase if “dial-up” connections are replaced by “fast Internet” broadcast channels

36 Webcasting Broadcasting over the internet - complementary to conventional over-air broadcasting Continuous live streaming On demand streaming On demand downloading Global access, full interactivity, personal filters, niche themes, audience monitoring Poor technical quality, but HOW POOR ? Compression schemes Network bandwidth, packet loss, jitter

37 Possible areas of common interest
Common receiver/terminal (human-machine interface) Portable/personal terminal (possibly integrated with a PDA) Common API protocols, interfaces and metadata Common networks and roaming strategies Common billing/security/transactional models Common IP technology for multimedia

38 Conclusion There are opportunities for broadcast and telecommunications to work together Synergy of the two platforms can strengthen both and enable new services and applications to develop UMTS should preferably be used for individual communication Broadcast channels are suited for high bitrate media distribution to large audiences Several scenarios for practical cooperation are possible Joint development and market activities are necessary to futher the business opportunities.

39 Conclusion In future broadcasters will probably become agnostic about delivery systems - they will use any broadcast or non-broadcast channel if it offers clear advantages for their audiences Broadcasters will use a variety of receiver terminals to reach their audiences Broadcasters will focus on the provision of rich content, increase diversity of programme choice develop attractive data/multimedia applications interactive broadcasting services
