Broadcasting in an Era of ConvergenceBroadcasting in an Era of Convergence
How does new technology and convergence affectbroadcasting ? (1)
User behaviour has changed(e.g. Radio, from past till today)
Stationary radio - audio only… same portable (e.g. kitchen radio, car radio)Stationary radio - with video (e.g. MTV, VIVA)… same portable, based on portable TV (e.g. over DVB-T)Mobile radio
Radio – audio onlye.g. FM receivers on mobile phones, DAB, Podcasting (Ipod, MP3)
Radio – with video and multimediae.g. DAB, DMB, DVB-H -> Mobile Broadcast

More service requirements – more services & more qualityRadio (e.g. audio only)Portable TV (SDTV)Stationary TV & Radio
Advanced quality (e.g. HDTV, surround sound)Mobile broadcast (Radio, Multimedia, TV / LDTV)Interactivity
More services require more programme distribution ways !

Competition in the use of frequenciesCompetition in the use of frequencies
Conclusion 1: additional service requirements and user behaviour
require more programme distribution waysrequire more frequency resources for emmission
Requirements for use of frequencies depends onService planning and goal for coverage
Frequency efficiencye.g. dense networks or broadcast networks
Network costsRegional/local population coverage or area coverage
Transmission system for emmissionNumber of programmes, quality, coverage size, goal for users

What is the business concept ?What is the business concept ?
Commercial benefitRevenue of mobile broadcast services in highly populated areas is 5 times higher compared to a full area coverageNo commercial reason to provide services in the full area, except if the market may be fully saturatedDigital Divide
Cheap access in cities No or expensive access in the area
Social political benefitTo offer a (sub)set of mobile free-to-air broadcast services to everybody everywhere independent whether they are rich or poor or whether they live in the country or in a city
