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 Standards 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 for 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 Digital Video Recorder, which removes the need for an external PVR, possibly requiring its own digital set-top box.
