Glossary
Bitstream
This is the digital form of multiple channel audio data (e.g., 5.1 chan- nel) before it is decoded into its various channels.
Dolby Digital
This is a method of coding digital signals developed by Dolby Labora- tories. Apart from stereo

DTS (Digital Theater Systems)
This surround system is used in many movie theaters around the world. There is good separation between the channels, so realistic sound effects are possible.
Dynamic range
Dynamic range is the difference between the lowest level of sound that can be heard above the noise of the equipment and the highest level of sound before distortion occurs.
Film and video
DVDs are recorded using either film or video. Usually, film is record- ed at 24 frames per second, the rate movies are filmed at, while video is recorded at 30 frames per second.
Frame
Frames are the still pictures that go together to make a moving picture. There are about 30 frames shown each second.
Interlace and progressive output
NTSC, the video signal standard, has 480 interlaced (i) scan lines, whereas progressive scanning uses twice the number of scan lines. This is called 480p. The 480i video signals output from this unit’s COMPONENT VIDEO OUT terminals (Y, PB, PR) allow you to enjoy higher quality pictures than if the signals were output from the video output terminal or S VIDEO OUT terminal. The COMPONENT VIDEO OUT terminals are also able to handle 480p (progressive) video signals which are of even greater resolution.
I/P/B
MPEG 2, the video compression standard adopted for use with DVD- Video, codes frames using these 3 picture types.
I:Intra coded picture
This is the standard picture and is a complete picture in itself.
This means it has the best picture quality and is the best to use when adjusting the picture.
P:Predictive coded picture
This picture is calculated based on past I or
B:
This picture is calculated by comparing past and future I and P- pictures so it has the lowest volume of information.
Linear PCM (pulse code modulation)
PCM is the usual digital method used for music CDs. DVDs have a greater volume so they use linear PCM, which has a higher sampling rate. Compressed PCM signals are called packed PCM (PPCM).
MP3
A method of compressing audio, MPEG Audio Layer 3 (MP3) allows audio to be reduced to up to one tenth its original size without overtly hurting audio quality.
When creating MP3 files to play on this unit
³Disc formats: ISO9660 level 1 and level 2 (except for extended for- mats)
Files: MP3 files with the suffix “.mp3” or “.MP3”
³To have this unit play files in a certain order, prefix folder and file names with numbers in the order you want to play them. This may not work in all cases.
³This unit is compatible with
Playback control
If a Video CD has “playback control” written on it or its jacket, it means that particular scenes or information can be selected for view- ing interactively with the television using the menu screen. This unit can play Video CDs with playback control.
Using menus to control play of a Video CD is called “menu play” in these operating instructions.
Title/Chapter
DVDs are divided up into large sections, titles, and smaller sections, chapters. The numbers allocated to these sections are called title numbers and chapter numbers.
Reference
Track
Video CDs and CDs are divided up into sections called tracks, and the numbers allocated to these sections are called track numbers.
