==Receiver==
There are two types of ISDB receiver: [[Television set|Television]] and [[set-top box]]. The aspect ratio of an ISDB-receiving television set is 16:9; televisions fulfilling these specs are called ''Hi-Vision TV''. There are four TV types: [[Cathode-ray tube]] (CRT), [[Plasma display|plasma display panel]] (PDP), [[OLED|organic light-emitting diode]] (OLED) and [[liquid crystal display]] (LCD), with LCD being the most popular ''Hi-Vision TV'' on the Japanese market nowadays.

The LCD share, as measured by [[JEITA]] in November 2004, was about 60%. While PDP sets occupy the high-end market with units that are over 50&nbsp;inches (1270&nbsp;mm), PDP and CRT set shares are about 20% each. CRT sets are considered low end for Hi-Vision. An STB is sometimes referred to as a digital tuner.{{citation needed|date=December 2011}}

Typical middle to high-end ISDB receivers marketed in Japan have several interfaces:

* [[F connector]]s for RF input.
* [[HDMI]] or [[D4 video connector|D4 connector]] for an [[High-definition television|HDTV]] monitor in a [[home cinema]].
* [[TOSLINK|Optical digital audio interface]] for an audio amplifier and speakers for [[Surround sound|5.1 surround audio]] in a home cinema.
* [[FireWire|IEEE 1394]] (aka FireWire) interface for digital data recorders (like [[DVD]] recorders) in a home cinema.
* [[RCA jack|RCA video jack]] provides [[SDTV]] signal that is sampled down from the HDTV signal for analog CRT television sets or [[VCR]]s.
* [[RCA jack|RCA audio jacks]] provide [[stereophonic sound|stereo audio]] for analog CRT television sets or [[VCR]]s.
* [[S-Video|S video]] is for [[VCR]]s or analog CRT television sets.
* [[10/100]] and modular jack telephone line [[Modem#Narrowband|modem]] interfaces are for an internet connection.
* B-CAS card interface to de-scramble.
* [[Infrared#Applications|IR]] interface jack for controlling a VHS or DVD player.
