Digital television (DTV) is the transmission of television signals using digital rather than conventional analog methods.
Advantages of DTV over analog TV include:
- Smaller bandwidth for a given image resolution
- Compatibility with computers and the Internet
- Superior audio quality
- Consistency of reception over varying distances
Digital television is not the same thing as HDTV (high-definition television). HDTV describes a new television format (including a new aspect ratio and pixel density), but not how the format will be transmitted. Digital television can be either standard or high definition.
