===History===
HDTV was invented at [[NHK Science & Technology Research Laboratories]] (Japan Broadcasting Corporation's Science & Technical Research Laboratories). The research for HDTV started as early as the 1960s, though a standard was proposed to the ITU-R (CCIR) only in 1973.<ref>{{Cite web|url=https://digitalcollections.library.cmu.edu/portal/main.jsp?flag=browse&smd=1&awdid=3|title=ArchivalWare >>Login|website=digitalcollections.library.cmu.edu|access-date=2018-09-14}}{{Dead link|date=August 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

By the 1980s, a high definition television camera, cathode-ray tube, videotape recorder, and editing equipment, among others, had been developed. In 1982 NHK developed MUSE (Multiple sub-Nyquist sampling encoding), the first HDTV video compression and transmission system. [[Multiple sub-Nyquist sampling encoding|MUSE]] used digital video compression, but for transmission [[frequency modulation]] was used after a digital-to-analog converter converted the digital signal.

In 1987, NHK demonstrated MUSE in Washington D.C. as well as NAB. The demonstration made a great impression in the U.S., leading to the development of the [[ATSC Standards|ATSC]] terrestrial DTV system. Europe also developed a DTV system called [[DVB]]. Japan began R&D of a completely digital system in the 1980s that led to ISDB. Japan began terrestrial digital broadcasting, using ISDB-T standard by NHK and commercial broadcasting stations, on 1 December 2003.

===Features===
[[File:ISDB-T CH Seg Prog allocation.svg|thumb|250px|Treeview of ISDB-T, channels, Segments and arranging multiple program broadcasting.]]

ISDB-T is characterized by the following features:

* ISDB-T (Integrated Services Digital Broadcasting-Terrestrial) in Japan use [[Ultra high frequency|UHF]] 470&nbsp;MHz-710&nbsp;MHz, bandwidth of 240&nbsp;MHz, allocate 40 channels namely channels 13 to 52 (previously used also 710&nbsp;MHz-770&nbsp;MHz, 53 to 62, but this range was re-assigned to cell phones), each channel is 6&nbsp;MHz width (actually 5.572&nbsp;MHz effective bandwidth and 430&nbsp;kHz guard band between channels). These channels are called "physical channel(物理チャンネル)". For other countries, US channel table or European channel table are used.
* For channel tables with 6&nbsp;MHz width, ISDB-T single channel bandwidths 5.572&nbsp;MHz has number of carriers 5,617 with interval of 0.99206&nbsp;kHz. For 7&nbsp;MHz channel, channel bandwidth is 6.50&nbsp;MHz; for 8&nbsp;MHz 7.42&nbsp;MHz.
* ISDB-T allows to accommodate any combination of HDTV (roughly 8&nbsp;Mbit/s in H.264) and SDTV (roughly 2&nbsp;Mbit/s in H.264) within the given bitrate determined by the transmission parameters such as bandwidth, code-rate, guard interval, etc. Typically, among the 13 segments, the center segment is used for [[1seg]] with QPSK modulation and the remaining 12 segments for the HDTV or SDTV payloads for 64QAM modulation. The bitstream of the 12 segments are combined into one transport stream, within which any combination of programs can be carried based on the [[MPEG transport stream|MPEG-2 transport stream]] definition.
* ISDB-T transmits an [[High-definition television|HDTV]] channel and a mobile TV channel '''[[1seg]]''' within one channel. 1seg is a mobile terrestrial digital audio/video broadcasting service in Japan. Although 1seg is designed for mobile usage, reception is sometimes problematic in moving vehicles. Because of reception on high speed vehicle, [[Ultra high frequency|UHF]] transmission is shaded by buildings and hills frequently, but reported well receiving in [[Shinkansen]] as far as run in flat or rural area.
* ISDB-T provides interactive services with data broadcasting. Such as [[Electronic program guide|Electronic Program Guides]]. ISDB-T supports internet access as a [[return channel]] that works to support the data broadcasting. Internet access is also provided on mobile phones.
* ISDB-T provides [[single-frequency network|Single-Frequency Network]] (SFN) and [[on-channel repeater]] technology. SFN makes efficient utilization of the frequency resource (spectrum). For example, the Kanto area (greater Tokyo area including most part of Tokyo prefecture and some part of Chiba, Ibaragi, Tochigi, Saitama and Kanagawa prefecture) are covered with SFN with roughly 10 million population coverage.
* ISDB-T can be received indoors with a simple [[indoor antenna]].
* ISDB-T provides robustness to [[multipath interference]] ("ghosting"), [[Co-channel interference|co-channel analog television interference]], and [[electromagnetic interference]]s that come from motor vehicles and power lines in urban environments.
* ISDB-T is claimed to allow HDTV to be received on moving vehicles at over 100&nbsp;km/h; [[DVB-T]] can only receive [[SDTV]] on moving vehicles, and it is claimed that [[ATSC Standards|ATSC]] can not be received on moving vehicles at all (however, in early 2007 there were reports of successful reception of ATSC on laptops using USB tuners in moving vehicles).

===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).

===Technical specification===
''' Segment structure '''

ARIB has developed a segment structure called [[Orthogonal frequency-division multiplexing#BST-OFDM used in ISDB|BST-OFDM]] (see figure).
ISDB-T divides the frequency band of one channel into thirteen segments. The broadcaster can select which combination of segments to use; this choice of segment structure allows for service flexibility. For example, ISDB-T can transmit both [[LDTV]] and HDTV using one TV channel or change to 3 SDTV, a switch that can be performed at any time. ISDB-T can also change the modulation scheme at the same time.

===ISDB-Tsb===
ISDB-Tsb is the '''t'''errestrial digital '''s'''ound '''b'''roadcasting specification. The technical specification is the same as ISDB-T. ISDB-Tsb supports the [[COFDM|coded transmission of OFDM signals]].

===ISDB-Tmm===
ISDB-Tmm ('''T'''errestrial '''m'''obile '''m'''ulti-media) utilised suitable number of segments by station with video coding MPEG-4 AVC/H.264. With multiple channels, ISDB-Tmm served dedicated channels such as sport, movie, music channels and others with [[CD]] quality sound, allowing for better broadcast quality as compared to [[1seg]]. This service used the [[VHF]] band, 207.5–222&nbsp;MHz which began to be utilised after Japan's [[Digital television transition|switchover to digital television]] in July 2011.
