Digital Terrestrial Television (DTT) is a method of broadcasting television signals using digital technology over terrestrial (land-based) transmitters. Unlike traditional analog signals, DTT provides clearer picture and sound quality, as well as more channels within the same frequency range. This technology allows viewers to receive broadcasts directly through an antenna without the need for cable or satellite services. DTT is widely used in many countries and has largely replaced analog television systems. It supports various features, such as high-definition (HD) programming and interactive services. To access DTT, viewers need a compatible television or a digital converter box to decode the signals.
