Here are a few definitions that build a foundation for more detailed information contained under the topics in the navigation menu located at the left of this page:

• DTV (Digital TV): DTV is a technology that uses digital communication (1s and 0s) instead of analog waves to transmit audio and video data to a television screen or monitor. Digital transmission requires less bandwidth than analog transmissions because digital data can be compressed. Compression makes it possible to deliver the increased amount of data required for High Definition TV (HDTV).

• High-Definition Satellite TV (HD Satellite TV): High-definition television delivered via a satellite instead of by a terrestrial cable.

• HDTV (High-Definition Television): Television broadcasted via a digital system that produces higher pixel resolution than traditional television systems such as NTSC, SECAM, and PAL.
