Digital TV refers to the transmission of television signals using digital technology instead of traditional analog methods. This allows for better picture and sound quality, as well as the ability to broadcast multiple channels over the same frequency. Digital TV can be received through various platforms, including cable, satellite, and over-the-air broadcasts. One of the key features of digital TV is its support for high-definition (HD) content, which provides a clearer and more detailed viewing experience. Additionally, digital TV often includes interactive features, such as video on demand and electronic program guides, enhancing the overall user experience.
