Abbreviation for Digital television. Any technology, using any of several digital Encoding schemes, used in connection with the Transmission and reception of television signals. Depending on the transmission medium, DTV often uses some type of Digital Compression to reduce the required digital Data rate. Except for artifacts of the compression, DTV is more immune (than analog television) to Degradation in transmission, resulting in a higher quality of both audio and video, to the limits of signal reception.
