During the digital television transition, several significant changes occurred:

High-Definition Television (HDTV): Digital broadcasting enabled the introduction of high-definition television, offering viewers much better resolution and clarity compared to standard-definition broadcasts.
Channel Capacity: Digital technology allowed broadcasters to transmit more channels using the same bandwidth. This capacity increase meant more programming options for viewers.
Channel Frequency Changes: In some cases, broadcasters changed their channel positions, moving from UHF (Ultra High Frequency) to VHF (Very High Frequency) or vice versa.
Additional Features: Digital broadcasting supports additional features like electronic program guides, multicasting, and interactive services.
NextGen TV: Recently, the introduction of ATSC 3.0, also known as NextGen TV, is bringing further upgrades such as improved audio and video quality, better reception, and enhanced accessibility features source.
These changes marked a significant milestone in television broadcasting, enhancing both the viewing experience and the technological capabilities of TV networks.
