Editing ISDB (section)

===Adoption===
ISDB-T was adopted for commercial transmissions in Japan in December 2003. It currently comprises a market of about 100 million television sets. ISDB-T had 10 million subscribers by the end of April 2005. Along with the wide use of ISDB-T, the price of receivers is getting low. The price of ISDB-T STB in the lower end of the market is ¥19800 as of 19 April 2006.<ref>{{Cite web|url=http://www.watch.impress.co.jp/av/docs/20060330/uniden3.htm|archive-url=https://web.archive.org/web/20070709074636/http://www.watch.impress.co.jp/av/docs/20060330/uniden3.htm|url-status=dead|title=uniden|archive-date=July 9, 2007}}</ref> By November 2007 only a few older, low-end STB models could be found in the Japanese market (average price U$180), showing a tendency towards replacement by mid to high-end equipment like PVRs and TV sets with inbuilt tuners. In November 2009, a retail chain [[Æon (company)|AEON]] introduced STB in 40 USD,<ref>{{Cite web|url=http://av.watch.impress.co.jp/docs/news/20090904_313051.html|title=イオン、4,980円のピクセラ製地デジチューナを発売|date=4 September 2009}}</ref> followed by variety of low-cost tuners. The Dibeg web page confirms this tendency by showing low significance of the digital tuner STB market in Japan.<ref>{{Cite web |url=http://www.dibeg.org/news/news-5/news-e5.htm |title=News-e5 |access-date=2007-11-22 |archive-url=https://web.archive.org/web/20071114023735/http://www.dibeg.org/news/news-5/news-e5.htm#dn068e |archive-date=2007-11-14 |url-status=dead }}</ref>

[[Brazil]], which used an [[broadcast television system|analogue TV system]] (PAL-M) that slightly differed from any other countries, has chosen ISDB-T as a base for its [[digital television|DTV]] format, calling it [[ISDB-Tb]] or ''internally'' [[SBTVD]] (''Sistema Brasileiro de Televisão Digital-Terrestre''). The Japanese DiBEG group incorporated the advancements made by Brazil -[[H.264|MPEG4]] video codec instead of ISDB-T's MPEG2 and a powerful interaction middleware called [[Ginga (SBTVD Middleware)|Ginga]]- and has renamed the standard to "[[ISDB-T International]]".<ref>{{cite web |url=http://www.dibeg.org/techp/feature/features_of_isdb-t.htm |title=Features of ISDB-T |access-date=2009-08-30 |url-status=dead |archive-url=https://web.archive.org/web/20090809234123/http://www.dibeg.org/techp/feature/features_of_isdb-t.htm |archive-date=2009-08-09 }}</ref> Other than Argentina, Brazil, Peru, Chile and Ecuador<ref name="blog.subtel.cl">{{cite web |url=http://blog.subtel.cl/wp/?p=105 |title=Archived copy |access-date=2009-09-14 |url-status=dead |archive-url=https://web.archive.org/web/20090922192948/http://blog.subtel.cl/wp/?p=105 |archive-date=2009-09-22 }}</ref> which have selected ISDB-Tb, there are other South American countries, mainly from [[Mercosur]], such as Venezuela,<ref>http://www.telesintese.ig.com.br/index.php?option=content&task=view&id=13284{{dead link|date=November 2017 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> that chose ISDB-Tb, which providing economies of scale and common market benefits from the regional South American manufacturing instead of importing ready-made STBs as is the case with the other standards. Also, it has been confirmed with extensive tests realized by Brazilian Association of Radio and Television Broadcasters (ABERT), Brazilian Television Engineering Society (SET) and [[Universidade Presbiteriana Mackenzie]] the insufficient quality for indoor reception presented by ATSC and, between DVB-T and ISDB-T, the latter presented superior performance in indoor reception and flexibility to access digital services and TV programs through non-mobile, mobile or portable receivers with impressive quality.<ref>{{cite web|url=http://www.set.com.br/artigos/nab.pps |title=Archived copy |access-date=2011-09-28 |url-status=dead |archive-url=https://web.archive.org/web/20110928163814/http://www.set.com.br/artigos/nab.pps |archive-date=2011-09-28 }}</ref>

The ABERT–SET group in Brazil did system comparison tests of DTV under the supervision of the [[CPqD]] foundation. The comparison tests were done under the direction of a work group of SET and [[ABERT]]. The ABERT/SET group selected ISDB-T as the best choice in digital broadcasting modulation systems among ATSC, DVB-T and ISDB-T.{{citation needed|date=August 2012}} Another study found that ISDB-T and DVB-T performed similarly, and that both were outperformed by [[DVB-T2]].<ref>Julian Clover [http://www.broadbandtvnews.com/2010/11/02/dvb-t-far-superior-to-isdb-dvb-t2-beats-them-both/ ''DVB-T far superior to ISDB, DVB-T2 beats them both''], in ''broadbandtvnews'' November 2, 2010</ref>

ISDB-T was singled out as the most flexible of all for meeting the needs of mobility and portability. It is most efficient for mobile and portable reception. On June 29, 2006, Brazil announced ISDB-T-based SBTVD as the chosen standard for digital TV transmissions, to be fully implemented by 2016. By November 2007 (one month prior DTTV launch), a few suppliers started to announce zapper STBs of the new Nippon-Brazilian SBTVD-T standard, at that time without interactivity.

As in 2019, the implementation rollout in Brazil proceeded successfully, with terrestrial analog services (PAL-M) phased out in most of the country (for some less populated regions, analog signal shutdown was postponed to 2023).
