AC-3 (Active Coding-3) - An audio encod-
ing technology developed by Dolby Laboratories.
AC-3 provides six channels of audio (known as
5.1) for front left, front right, front center, rear
left, rear right, and subwoofer. AC-3 technology
is used in Dolby Digital surround sound.
Aspect Ratio - The ratio of screen width to
height. The aspect ratio of the standard TV
screen is 4:3. The high-definition TV (HDTV)
format is 16:9. When a widescreen movie is
shown on a 4:3 TV there are two ways to dis-
play the image:
• 4:3 Letter Box - The entire original
screen frame is displayed on the TV. However,
this results in extra space (black bars) above
and below the frame.
• 4:3 Pan & Scan: The image fills the
entire TV screen, but in order to do so, the
original frame must be truncated at the sides,
so the viewer does not see the entire original
screen image. When something important
needs to be shown but it is located out of
frame, the view pans over to reveal the hidden
portion of the original image.
Bit Depth - The number of data bits used to
encode a sample analog signal when it is con-
verted into digital data. Higher bit depth means
higher resolution and therefore higher fidelity.
CD (Compact Disc) - A digital audio disc
that contains up to 74 minutes of hi-fi stereo
sound. The most common platter size is
120mm (4.75") in diameter, recorded on one
side, with individual selections playable in any
sequence. Other forms of CDs, such as Video
CD, stem from the original Compact Disc-
Digital Audio (CD-DA) format.
