GLOSSARY

Aspect ratio

els are 16:9 (the screen is almost
twice as wide as its height).
Component video
This is a video signal format that
conveys each of three principal
colors of light (red, blue and

nal formats, including Y / Pb / Pr
and Y / Cb / Cr.
Dolby Digital
The system developed by Dolby
Laboratories to compress digital
sound. It offers stereo sound (2ch)

IR SIGNAL CHECK
If the remote control isn't working properly, you can
use an AM radio or digital camera (including a cellu-
lar phone with built-in camera) to see if it is sending
out an infrared signal.
• With an AM radio:
Tune the AM radio station to a
non-broadcasting frequency.
Point the remote control towards
it, push any button and listen. If
the sound from the radio flutters,
it is receiving the remote control's
infrared signal.
• With a digital camera
(including built-in cell phone cameras):
Point a digital camera towards the
remote control. Push any button on the
remote control and look through the digi-
tal camera. If the infrared light appears
through the camera, the remote control
is working.
