Interlace and progressive output

NTSC, the video signal standard, has 525 interlaced (i) scan lines, whereas progressive scanning uses twice the number of scan lines.

This is called 525p. The 525i video signals output from this unit’s COMPONENT VIDEO OUT terminals (Y, PB / CB, PR/CR) 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 525p (progressive) video signals which are of even greater resolution.

I/P/B

MPEG, the video compression standard adopted for use with DVD-Video, codes frames using these 3 picture types.

I:Intra coded picture (I-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 (P-picture)

This picture is calculated based on past I or P-

pictures.

B:Bidirectionally-predictive coded picture (B-picture) This picture is calculated by comparing past and future I and P-pictures so it has the lowest volume of information.

LFE 0.1 channel

This channel is for the reproduction of low bass signals. The frequency range for this channel is 20 Hz to 120 Hz. This channel is counted as 0.1 because it only enforces a low frequency range compared to the full-range reproduced by the other 5 channels in a Dolby Digital or DTS 5.1 channel systems.

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).

GLOSSARY

Matrix 6.1

The unit incorporates Matrix 6.1 decoder for Dolby Digital and DTS multi-channel software that enables 6.1- channel reproduction by adding the rear center channel to existing 5.1-channel format. (The rear center channel is created from rear left and right channels, and outputted from virtual rear center speaker.) With this additional channel, you can experience more dynamic and realistic moving sound especially with scenes with “fly-over” and “fly-around” effects.

Pan&Scan/Letterbox

In general, DVD-Video are produced with the intention that they are viewed on a widescreen television with an aspect ratio of 16:9. This means you can view most material with the intended aspect ratio on a widescreen television.

Material with this ratio will not fit onto a standard television with an aspect ratio of 4:3. Two styles of picture, “Pan&Scan” and “Letterbox”, deal with this problem.

Pan&Scan: The sides are cut off so the picture fills the screen.

Letterbox: Black bands appear at the top and bottom of the picture so the picture itself appears in an aspect ratio of 16:9.

Playback control (PBC)

APPENDIX

 

If a Video CD has “playback control” written on it or its

 

jacket, it means that particular scenes or information can

 

be selected for viewing 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.

 

Sampling frequency and number of

 

quantized bits

 

When digitizing an analog audio signal, the number of

 

times the signal is sampled per second is called the

 

sampling frequency, while the degree of fineness when

 

converting the sound level into a numeric value is called

 

the number of quantized bits.
