Definition: ISDB

(Integrated Services Digital Broadcasting) The Japanese mobile TV and digital radio standard. Replacing the earlier analog HDTV system (see Hi-Vision) and based on MPEG-2, ISDB transmits 50 channels (13 through 62) in the UHF bands from 470 to 770 MHz. Following are the various ISDB flavors. Brazil adopted ISDB-T for the Latin and South American markets (see SBTVD). The 1 seg standard means "one segment" out of the 13 ISDB-T segments is used for TV on smartphones. See mobile TV.
