HDTV
Benefits of the Digital modulation: Flexibility
All HD programs in France are MPEG-44 free-to-air and 1 pay channel
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
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
Value Added Services economic model to be determined
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
