An Integrated Digital Television (IDTV or iDTV) set is a television set with a built in digital tuner, be it for DVB-T, DVB-S, DVB-C, DMB-T/H, ATSC or ISDB. Most of them also allow reception of analogue signals (PAL, SÉCAM or NTSC). They do away with the need for a set top box for converting those signals for reception on a television. Some are integrated with a personal video recorder, such as LG's Time Machine TV.
Most iDTVs do not inherently support pay TV, and as a result many are fitted with Common Interface slots to allow the use of a conditional access module. They may also include support for other features of a digital television "platform", such as an interactive television engine and support for some form of return channel. A small number of iDTVs include a PVR, which removes the need for an external PVR, possibly requiring its own digital set-top box.
