Bitstream
This is a signal compressed and converted into digital form. It is converted back to a
CPRM (Content Protection for Recordable Media)
CPRM is technology used to protect broadcasts that are allowed to be recorded only once. Such broadcasts can be recorded only with CPRM- compatible recorders and discs.
Decoder
A decoder restores the coded audio signals on DVDs to normal. This is called decoding.
Deep Colour
This unit incorporates HDMI (V.1.3a with Deep Colour) technology that can reproduce greater colour gradation (4096 steps) when connected to a compatible TV.
You can enjoy exceptionally rich,
[A lower colour gradation (256 steps), without Deep Colour, will be reproduced if connected to a TV which does not support Deep Colour. The unit will automatically set appropriate output to suit the connected TV.]
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
When recording on this unit Dolby Digital (2 channel) is the default audio.
Down-mixing
This is the process of remixing the
Drive
In the instance of this unit, this refers to the disc (DVD) and video cassette (VHS). These perform the reading and writing of data.
DTS (Digital Theater Systems)
This surround system is used in many movie theaters. 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. Dynamic range compression means reducing the gap between the loudest and softest sounds. This means you can hear dialogue clearly at low volume.
Film and Video
Film: | Recorded at 25 frames per second (PAL discs) or 24 |
| frames per second (NTSC discs). (NTSC discs |
| recorded at 30 frames per second as well.) |
| Generally appropriate for motion picture films. |
Video: | Recorded at 25 frames/50 fields per second (PAL |
| discs) or 30 frames/60 fields per second (NTSC |
| discs). Generally appropriate for TV drama |
| programmes or animation. |

Folder
This is a place on the disc where groups of data are stored together. In the case of this unit, it refers to the place where still pictures (JPEG) are stored.
Formatting
Formatting is the process of making media such as
You can format
Formatting irrevocably erases all contents.
Frame and Field
Frame refers to the single images that constitute the video you see on your TV. Each frame consists of 2 fields.

Frame | Field | Field |
≥A frame still shows 2 fields, so there may be some blurring between them, but picture quality is generally better.
≥A field still shows less picture information so it may be rougher, but there is no blurring.
HDMI (High-Definition Multimedia Interface)
Unlike conventional connections, it transmits uncompressed digital video and audio signals on a single cable. This unit supports high- definition video output [720p (750p), 1080i (1125i) and 1080p (1125p)] from HDMI AV OUT terminal. To enjoy
JPEG (Joint Photographic Experts Group)
This is a system used for compressing/decoding color still pictures. If you select JPEG as the storage system on digital cameras, etc., the data will be compressed to
LPCM (Linear PCM)
These are uncompressed digital signals, similar to those found on CDs.
MPEG2 (Moving Picture Experts Group)
A standard for efficiently compressing and expanding colour video. MPEG2 is a compression standard used for DVD and satellite based digital broadcasting. This unit records programmes using MPEG2.
MP3 (MPEG Audio Layer 3)
An audio compression method that compresses audio to approximately 1/10 of its size without any significant loss of audio quality.
Pan & Scan/Letterbox
In general,
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)
If a Video CD has playback control, you can select scenes and information with menus on the screen.
(This unit is compatible with version 2.0 and 1.1.)
