Bitstream
This is the compressed form of digital signals. A decoder decodes 
these signals into 5.1 surround and multi-channel signals.
Channel (when referring to DVD)
Sound is divided into channels based on the sound’s role.
For example, 5.1 channel
≥Front speakers — 1 left channel and 1 right channel
≥Center speaker — 1 channel
≥Surround speakers — 1 left channel and 1 right channel
≥Subwoofer — 1 channelk0.1 (the ratio of bass to the total amount 
of sound output)
Examples as shown in the on-screen menus
(1) 1: Subwoofer signal 
(not displayed if there is no subwoofer signal)
(2) 0: No surround
1: Mono surround
2: Stereo surround (left/right)

Direct navigator
This is a list of programmes you have recorded. You can select 
programmes from the list to view. The list also shows the date and 
time of recording, the channel, and the titles of titled programmes. 
The selected programme is played in the background, making 
selection even simpler.
Dolby Digital
This is a method of coding digital signals developed by Dolby 
Laboratories. Apart from stereo (2 channel) audio, these signals 
can also be 5.1-channel audio. A large amount of audio 
information can be recorded on one disc using this method.
Dolby Pro Logic
A surround system where a 4-channel audio track is recorded as  2 
channels and then is restored to 4 channels for play. The surround 
channel is monaural.
DTS Digital Surround
This surround system is used in many movie theaters around the 
world. The separation between channels is good and the 
compression ratio is low, so realistic sound effects are possible.
DTS soundtracks are produced with the assumption that all 
channels will be used.
