C
R
) is independent to output so that you can experience
picture Color as it is. Also, due to compatibility with
progressive video (525p/480p), you can experience
higher-density picture than that in interlace (525i/480i).
Digital Audio
An indirect representation of sound by numbers. During
recording, the sound is measured at discrete intervals
(44,100 times a second for CD audio) by an analog-to-
digital converter, generating a stream of numbers. On
playback, a digital-to-analog converter generates an
analog signal based on these numbers.
