DTB is an acronym that stands for "Digital Terrestrial Broadcasting." It refers to the transmission of television and radio signals over the airwaves using digital technology, as opposed to traditional analog broadcasting. In DTB, the audiovisual content is converted into a digital signal and transmitted through terrestrial channels, such as antennas, to reaching viewers and listeners.
DTB offers various advantages over analog broadcasting. One major benefit is improved signal quality, resulting in higher resolution, clearer images, and better sound quality. Digital signals are also more robust and resistant to interference and signal degradation, providing a more reliable viewing and listening experience. Furthermore, DTB allows for additional features, such as electronic program guides, closed captions, and multiple audio tracks, enhancing the user experience.
The transition from analog to DTB has taken place in many countries worldwide, driven by the availability of digital technologies and the need to free up valuable spectrum resources. This shift has opened up new channels and frequencies for broadcasting, enabling the delivery of more diverse and specialized content along with traditional offerings. DTB is also a key enabler for other digital services, such as interactive television and multimedia streaming.
Overall, DTB revolutionizes the way television and radio signals are transmitted, providing consumers with enhanced audiovisual experiences and broadcasters with new possibilities for delivering content.
