Linear PCM (LPCM)/Pulse code modulation

This stands for linear pulse code modulation, which is the signal recording system used for music CDs and DVDs. Generally, DVDs are re- corded with higher sampling frequency and bit rate than CDs. Therefore, DVDs can provide higher sound quality.

m3u

Playlists created using the “WINAMP” soft- ware have a playlist file extension (.m3u).

MP3

MP3 is short for MPEG Audio Layer 3. It is an audio compression standard set by a working group (MPEG) of the ISO (International Stan- dards Organization). MP3 is able to compress audio data to about 1/10th the level of a con- ventional disc.

MPEG

This stands for Moving Pictures Experts Group, and is an international video image compression standard. Some DVDs feature di- gital audio compressed and recorded using this system.

MS ADPCM

This stands for Microsoft adaptive differential pulse code modulation, which is the signal re- cording system used for the multimedia soft- ware of Microsoft Corporation.

Multi-angle

With regular TV programs, although multiple cameras are used to simultaneously shoot scenes, only images from one camera at a time are transmitted to your TV. Some DVDs feature scenes shot from multiple angles, let- ting you choose your viewing angle as desired.

Multi-audio (Multilingual dialog) Some DVDs feature dialog recorded in multi- ple languages. Dialog in up to 8 languages

can be recorded on a single disc, letting you choose as desired.

Multi-session

Multi-session is a recording method that al- lows additional data to be recorded later. When recording data on a CD-ROM, CD-R or CD-RW, etc., all data from beginning to end is treated as a single unit or session. Multi-ses- sion is a method of recording more than 2 ses- sions on one disc.

Multi-subtitle

Subtitles in up to 32 languages can be re- corded on a single DVD, letting you choose as desired.

Number of quantization bits

The number of quantization bits is one factor in the overall sound quality; the higher the “bit-depth”, the better the sound quality. How- ever, increasing the bit-depth also increases the amount of data and therefore storage space required.

Packed PCM

A lossless compression system that enables more PCM audio to be stored on a DVD audio disc than would otherwise be possible.

Packet write

This is a general term for a method of writing on CD-R, etc., at the time required for a file, just as is done with files on floppy or hard discs.

Parental lock

Some DVD video discs with violent or adult-or- iented scenes feature parental lock which pre- vents children from viewing such scenes. With this kind of disc, if you set the unit’s parental lock level, playback of scenes inappropriate for children will be disabled, or these scenes will be skipped.
