DiBcom, the Heart of Mobile TV . DVB-H in the world . DVB-H receiver Quality and its effect on Network Cost . Conclusion 20 October 2006 26 CONCLUSION DVB-H is the world’s most efficient standard for Mobile TV applications DVB-H receiver compliance is not sufficient Small differences in DVB-H receiver quality (Sensitivity, Doppler compensation,..) can have enormous consequences when it comes to: Network Quality (especially coverage) and cost ! The “Proven Performance” receiver also known as the “Possible Reference Receiver” (DVB-H Implementation Guidelines) is becoming a “de facto” standard thanks to the world’s first DVB-H commercial launch in Italy. 20 October 2006 27 Thank you HEADQUARTERS Parc Gutenberg 2 bis, voie La Cardon FRANCE 91120 Palaiseau [email protected] FRANCE ▪ Headquarters Tel : +33(0)1 69 32 11 16 ▪ R & D ▪ Sales and Marketing Fax : +33(0)1 69 32 25 54 ▪ Test and Production ▪ Power Management Tel: +33(0)1 69 32 11 16 GERMANY [email protected] ▪ Business Development Tel: +49 (0)9288 957840 EUROPE SWEDEN ▪ R & D ASIA PACIFIC [email protected] ▪ Sales Department TAIWAN (Taipei) Tel : +886 (0)2 8752 6960 NORTH AMERICA P.R.
