DTV, or Digital Television, refers to the transmission of television signals using digital encoding rather than the traditional analog method. This technology allows for improved picture and sound quality, as well as the ability to broadcast multiple channels over a single frequency. DTV can be received through various platforms, including cable, satellite, and over-the-air broadcasts. The transition from analog to DTV was completed in the United States in June 2009, marking the end of analog television broadcasts. This shift has enabled the development of high-definition (HD) programming and interactive services, enhancing the viewing experience for audiences.
