ＤｉＢＥＧ Digital Broadcasting Experts Group DTV Trials in the World • Singapore, mda – 1999 – The Panel concluded that the DVB and ISDB-T systems will work for this application.(5. Mobile TV, p.4) – ISDB commercial applications is not available... (in 1999) • Hong Kong, OFTA,ATV,TVB – 1999 – Mobile reception of ISDB-T and DVB-T was good in open areas.(5. Support of Mobile reception, p.4) – Report on the technical trial of digital terrestrial television(DTT) Digital Terrestrial Television Steering Committee (executive summary) • Brazil, ABERT/SET, ANATEL – 1999/2000 – If you look into our test report, the best performance, by far, is the ISDB- T COFDM proposal. The biggest problem is the fact that Japan is schedule to start the terrestrial transmission only in 2003. – Why we are choosing COFDM for Brasil, HDTV news Sunday April 9 2000(Fernando Bittencourt :Chairman ABERT/SET group) ＤｉＢＥＧ Digital Broadcasting Experts Group

ISDB-T has launched in Tokyo, Osaka and Nagoya areas. And ISDB-Tsb has already launched. ISDB-T can receive in Mobile/Portable environment. ISDB-T brings robustness to multi-path interference in fixed reception. ISDB-T provides effective utilization of Frequency with SFN. ISDB-T is the most flexible system among the DTTV standards.
