Difference Between DVB-T and ISDB-T

Difference Between DVB-T ISDB-T

Distinct differences exist between digital video broadcasting (DVB) and integrated services digital broadcasting (ISDB). Those DVB-T & ISDB-T broadcasting formats are used in different parts of the world. The “T” in “DVB-T” and “ISDB-T” stands for “terrestrial,” and it designates a more international form of each original broadcasting system.

DVB

DVB is a widely used system that accepts certain standards to run programming. It is a set of guidelines set up by the DVB Project, which is a board consisting of international members. The organization is European-based, but DVB is used in countries throughout the world. DVB offers data distribution in several ways, such as satellite, cable, terrestrial television and microwaves.

ISDB-T

ISDB-T

ISDB is a much less widespread alternative to DVB. It was developed in Japan and built for use in that country. It is used by Japan’s analog radio and television systems as well as all of its digital television and radio systems. ISDB-T can be used to broadcast high-definition television shows and display information from a mobile device such as a cellphone called One-Segs at the same time.

DVB-T & ISDB-T

While DVB was originally built for use in Europe, it can be used throughout the world with DVB-T. Countries that use DVB include South Africa, Kenya, Iran, Israel, New Zealand and Malaysia.

ISDB-T was created in Japan in 2003, but it didn’t leave the country until Brazil began using it in 2007. ISDB-T became fully international by mid-2011, although mainly only in South America. The countries in which it is represented include Chile, Argentina and Peru.

Differences

The DVB-T system offers 6, 7 and 8 MHz receivers, which means they can broadcast at the three speeds. ISDB-T does not offer receivers with 7 or 8 MHz capabilities. That is the only major difference between DVB-T and ISDB-T, however, because both use coded orthogonal frequency division multiplexing (COFDM) modulation technology. That factor makes both of them produce a similar performance.
