Integrated - When set-top box like functions are built into the device so partnering it with a separate set-top box or equivalent, is not necessary. In the past these were sometimes referred to as "built-ins".
Integrated Digital TV (Integrated Digital Television, Integrated TV, iDTV, Advanced High Definition Television) (Associated with Smart TVs, PCTVs, PC-TVs, PC to TV Signal Converter, Computer Televisions, Next Generation TVs, Integrated Smart Televisions, TVPCs, Multimedia Television, Intelligent TV Sets, Full-service Integrated Interactive TVs, IDTV.) - The term "Integrated Television" was more popular several years ago. It was an impressive smart TV with some media center type functionality built-into it. Fortunately it has been re-born with vigor as the Integrated Digital Television (iDTV). iDTV are digital TVs with media center features such as built-in Internet connectivity, electronic program guides, personal planner, on-screen prompts for all sorts of good stuff and more. The iDTV may contain a media extender so you can enjoy digital entertainment directly from your PC, a home media server or from the Internet.https://en.wikipedia.org/wiki/Integrated_Digital_Television
iDTVs can also have built-in digital tuners, demodulators, and source decoders, thus they do not need to be hooked up to digital set-top boxes (or equivalent devices) to receive digital broadcasts. Integrated TVs often perform both security (i.e. decryption of the cable signals) and non-security functions. See Digital TV.
Integrated High Definition TV Sets (HD IDTV) - (Integrated Digital TV Sets, Integrated Digital Television) – These are high definition digital TVs which are manufactured with both the HDTV monitor and HDTV receiver in a single unit, versus when the HDTV is basically only a HDTV monitor and thus requires a set-top box (or equivalent device) to act as a tuner/receiver. SDTV (analog TVs) have built-in receivers but many HDTVs don't; consequently the consumer is often dependent on their network operator to provide the HDTV receiver. Alternatively, this transmitted data (signal) might first need to be decoded by your cable, telco or satellite TV, etc. provider before it's sent to the viewer.
The FCC has mandated HDTV tuners be integrated (built into) HDTVs progressively starting in 2004 (depending on the size of the TV.) The major benefit to this is that people can the receive free high quality HDTV signals over the air (a.k.a. free-over-the-air) with an inexpensive household antenna and thus not need to subscribe to satellite or cable TV to get HDTV reception.
