7. Benefits of the Digital modulation: new services Content : International, National and/or Local content. National and/or Commercial Broadcasters SDTV, EDTV, HDTV, INTERNET Access, DATA BROADCASTING (MPEG2 and/or MPEG4) Multiplex allocation Fixed, portable and/or mobile reception Pay TV, impulse Pay Per View, free services Type of electronic program guide (EPG) and access control management system (CA) …. (non exhaustive) Decision to make in terms of new services types The fundamental approach: to start from services in order to define the structure of the network and to prepare the national audiovisual law

8. Value Added Services economic model to be determined Free to air (Basic bouquet ) Commercial/Thematic programs : subscription Impulse Pay per view : sport events, … NVOD, Home Shopping (purchasing via STB), E commerce National annual TV fee, Set top box : Free of charge Sold Rented Leased Benefits of the Digital modulation: value added services The dominant model in Europe is a free to air platform with some pay elements in MPEG-4

9. Advantages for the content providers Opportunity to develop innovative content Can converge with Telecom operators to offer mobile services Infrastructure delivers data therefore encourages development and expansion of data services: new business model New added value services can be added Associated data groups for accessibility, control, monitoring and Quality of Services system and service data (e.g. EPG, diagnostics, automation..) Digital modulation benefits for Broadcasters

10. Advantages for Manufacturers Analogue TV is old – room for innovation (market differentiation) is limited Digital TV involves new set-top-box reception equipment, and potentially for higher quality displays (e.g. HDTV) => innovation Consumer devices such as PVR, home networking require digital services Head-end vendors can provide more flexibility, systems than previously Convergence provides interest challenges for manufacturers Digital modulation benefits for Manufacturers

11. Advantages for Governments Digital dividend thanks to the spectrum frequency. New network planning issues has to be considered after the analogue TV switch off. Promote competition as more actors can enter into the market Digital requires less RF power so this leads to energy’s cost savings and cost of ownership gain . SFN mean you could have one RF frequency occupancy by multiplexed TV programs over the countrywide . Extension of the nationwide coverage: diversity and access to a wider range of population Gives prominence to the public service broadcasters Improves enforcement of regulation of broadcasting content Stimulates content providers Digital modulation benefits for Governments

12. Advantages for Consumers Access to new services means increased choice and new system information Better choice or higher quality programs possible Digital also means access to whole range of new consumer products like PVR, flat screens... Digital modulation benefits Consumers
