Frequently Asked Questions
About HDTV
A R E L O C A L TV S T AT I O N S B R O A D C A S T I N G I N HDTV?
Many local TV stations are transmitting digital signals. However, transmitting a digital signal does not
mean transmitting an HDTV signal. Some stations are using the new bandwidth to broadcast several
standard-definition channels. Most stations however, once they begin broadcasting in digital are offering
HD content from their parent station (i.e. CBS, ABC, NBC, Fox, WB, UPN, or PBS).
W H Y A R E S O M E HDTV S 4: 3 A S P E C T R AT I O A N D O T H E R S 16:9?
The aspect ratios differ because the television industry manufactures both standard and wide-screen
HDTVs, to appeal to consumer viewing preferences.
•
•
On wide-screen HDTVs, the programming is displayed on the full screen.
On standard HDTVs, the programming is displayed in letter-box format in the middle of the screen.

The HDTV is 1/3 wider than a traditional TV. The HDTV aspect ratio is 16:9 (compared to 4:3 for
SDTV).
HDTV uses a much finer resolution to create the TV picture—1125 lines for HDTV compared to 525
lines used in SDTV. This means that the resolution for HDTV can be up to 1920x1080 pixels,
compared with 720x480 for SDTV.
In the USA, HDTV is always broadcast with digital signals. SDTV is currently broadcast in both digital
and analog. (However, HDTV and digital SDTV do not use the same digital signal.)
Generally all HDTV-ready monitors or integrated HDTV sets are capable of supporting an SDTV 480i
or 480p signal. Not all HDTV monitors support both 720p and 1080i HDTV signals. For instance,
some plasma displays only support 720p.
