Modern DTV systems sometimes use a return path providing feedback from the end user to the broadcaster. Digital Signage ist ein Sammelbegriff für programmgesteuerte Bildschirme außerhalb der eigenen vier Wände. [8][9] DCT coding is a lossy compression technique that was first proposed for image compression by Nasir Ahmed in 1972,[10] and was later adapted into a motion-compensated DCT video coding algorithm, for video coding standards such as the H.26x formats from 1988 onwards and the MPEG formats from 1991 onwards.

Although incompatible with the existing NTSC standard, the new DTV standard would be able to incorporate many improvements. Prior to the conversion to digital TV, analog television broadcast audio for TV channels on a separate FM carrier signal from the video signal. However, broadcasters may choose to reduce these resolutions to reduce bit rate (e.g., many DVB-T channels in the United Kingdom use a horizontal resolution of 544 or 704 pixels per line).[19]. DTV also permits special services such as multiplexing (more than one program on the same channel), electronic program guides and additional languages (spoken or subtitled).
