ARIB Technical Reports (published in June, 2007)
ISDB-T (Integrated Service Digital Broadcasting - Terrestrial) has been developed and now on service in Japan, and adopted by Brazil.
ISDB-T proves best performances in Japanese DTTB service for more than 3 years.
Since Dec. 2003, start of Japanese DTTB service, DTTB service is rapidly migrated because of its advantages, and new service, named "One-seg", portable reception service in same channel, has been started from April 2006.
But, because of late start of ISDB-T, ISDB-T is not so popular in the world, so, we will submit this technical report to South America countries to understand the ISDB-T system and its advantages on technical aspect.
Now, 3 major DTTB( Digital Terrestrial TV Broadcasting) systems exist.These are called:
|(1)||ATSC: Advanced Television System Committee, Developed in USA, and now used.|
|(2)||DVB-T: Digital Video Broadcasting – Terrestrial, developed in EU, and now used.|
|(3)||ISDB-T: Integrated Service Digital Broadcasting – Terrestrial, developed in Japan and now used in Japan and Brazil.|
