Why do some programs look “clearer” than others on my digital television?

Depending on your television, you may notice the resolution of the picture changing between programs.

With a higher resolution television, lower resolution channels or programming will appear in their lower

resolution. Therefore, switching between a channel or program that is broadcast at a high resolution to a

channel or program of a lower resolution will result in a visible loss of image quality.

Resolutions that broadcasters may use include:

Standard Definition TV (SDTV) - SDTV is the basic level of

quality display and resolution for both analog and digital.

Transmission of SDTV may be in either the traditional (4:3) or

widescreen (16:9) format and consists of 480 interlaced lines of

resolution.

Enhanced Definition TV (EDTV) - EDTV is a step up from

analog television and Standard Definition digital television.

EDTV comes in widescreen (16:9) or traditional (4:3) format

and provides 480 progressively scanned lines of resolution. This

is approximately twice as much resolution as SDTV and is the

format most often found on DVDs.

High Definition TV (HDTV) - HDTV in widescreen format

(16:9) provides the highest resolution and picture quality of all

digital broadcast formats. It consists of either 1080 interlaced

or 720 progressively scanned lines of resolution and includes

the ability to transmit digital surround sound.

Some people who live in an apartment building, condominium, home owners’ association, high-rise, co-op

or other multiple dwelling unit (MDU) receive local TV stations through a master antenna system,

sometimes called a common antenna or a MATV system. These antenna systems receive TV signals

through an antenna on the roof or in a central location and provide the signals through wiring in the

building or development that connects to the TV set in individual apartments or homes. Some of these

systems provide the local TV stations for free, and some of them are packaged with satellite programming

and charge a fee. These shared or community antenna systems are sometimes known as “satellite master

antenna systems,” or “SMATVs”. Also, some people who live in MDUs receive local TV stations
