Dolby Digital (page 19, 67)
Digital audio compression technology
developed by Dolby Laboratories. This
technology conforms to multi-channel
surround sound. The rear channel is stereo
and there is a discrete subwoofer channel in
this format. Dolby Digital provides the same
multi discrete channels of high quality digital
audio found in Dolby Digital cinema audio
systems. Good channel separation is realized
because all of the channel data are recorded
discretely and little deterioration is realized
because all channel data processing is digital.

multi-channel format, such as Dolby Digital,
allowing you to enjoy a more real audio
presence.
Furthermore, various advanced functions
such as the multi-angle, multilingual, and
