Integrated digital television

As IDTV ( Integrated Digital Television engl. ), rarely iDTV, televisions are referred to, in which a receiver for digital TV is integrated ( for DVB, ATSC or ISDB standard). The DVB calls such devices in its documents IRD, integrated receiver display.

Many such devices have continued an analog PAL, SECAM, and / or NTSC receiver. Such devices need to watch DTV no ​​separate set- top box ( STB); Requirements such as encryption of data on the cable between the STB and the display are largely eliminated.

Some devices do not support subscription cards from pay-TV providers, ie without an external decoder only free -to-air television (FTA, free to air ). Other devices provide an interface (Common Interface, CI ) is available, into which a module (Conditional Access Module, the CAM ) may be used, which in turn receives the card. From separate receivers known functions are also possible. These include program guide ( EPG electronic program guide), rear -channel capability for interactive television (eg MHP) or recording and playback capabilities using hard disks or DVDs ( PVR, personal video recorder ).

After ATSC and ISDB for the American and Korean or Japanese market is also increasingly DVB -T, often supported in combination with the technically very similar DVB- C and / or DVB -S. Such devices perform, for example, Artec, Humax, Loewe, Metz, Sharp, Sony, TechniSat, Thomson, X4-Tech, Samsung and Toshiba.

IDTV with integrated PC

In 2007, the renowned Danish consumer electronics maker Bang & Olufsen announced " the future will be equipped B & O TV with a Microsoft operating system." In addition to the consolidation of telecommunications from formerly separate networks for voice and data into a single Next Generation Network ( NGN), a unified user interface of the PC and TV is the future, where a single device to a PC operating system in the TV. Conventional television manufacturers see such developments with Argus eyes, with all the previous bound to a TV accessories such as DVD players, VCRs or AV amplifier would be endangered but with such a development. Proponents argue, however, that an operator of a PC is now common knowledge, programming a VCR but still a majority of users do not succeed because of a per device and manufacturer proprietary user interface. It is characteristic of such fears that continue to support some flat screen TV ( eg Philips) today to connect a PC only insufficiently.

  • A TV with a built-in PC operating system also brings a web browser and thus as new content "Internet " on the TV screen.
  • Previous efforts for interactive television (Multimedia Home Platform, Betty (remote control), Blucom ) would be obsolete with a PC operating system through a browser access to all web content on the TV screen.
  • Accessories for consumer electronics would be redundant with a PC operating system and would be replaced by PC accessories.
