Mpeg video, Multi-session, Sampling frequency

MPEG video

The video format used for Super VCDs/Video CDs and DVDs. Super VCDs/Video CDs uses the older MPEG-1 standard, while DVD uses the newer and much better quality MPEG-2 stan- dard.

Multi-session

A CD-R/RW that contains two or more ‘ses- sions’. Each session is a complete recording process, so each session is read as a complete disc. This player can only read the first session on a disc.

Optical digital output

A jack that outputs digital audio in the form of light pulses. Connect components with optical digital jacks using a special optical cord, available from good audio dealers.

Packed PCM (DVD-Audio only)

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

PCM (Pulse Code Modulation)

The most common system of encoding digital audio, found on CDs and DAT. Excellent quality, but requires a lot of data compared to formats such as Dolby Digital and MPEG audio. For compatibility with digital audio recorders (CD, MD and DAT) and AV amplifiers with digital inputs, this unit can convert Dolby Digital, DTS and MPEG audio to PCM. See also Digital audio.

PBC (PlayBack Control) (Super VCD/Video CD only)

A system of navigating a Super VCD/Video CD through on-screen menus recorded onto the disc. Especially good for discs that you would normally not watch from beginning to end all at once—karaoke discs, for example.

Progressive scan video

Also called non-interlaced video, this method of displaying a picture updates all the lines in one pass, resulting in a more stable, flicker-free image than interlaced video (for a given scanning rate). See also Interlaced video.

Additional Information 8

PureCinema (DVD-Video only) Video on a DVD discs may be either video material (originally shot on video) or film material (originally shot on film). Video material has a frame rate of 30 frames/sec.(NTSC), compared with 24 frames/sec. for film. This player converts film material to 60 frames/sec. (in progressive scan mode). PureCinema adjusts the picture so that it matches more closely the picture quality of a cinema screen.

You can see whether video on a DVD disc is film or video material by displaying the video transmission rate (see page 34). If a hash mark

(#) appears above the transmission rate display, it is film material.

Regions (DVD-Video only)

These associate discs and players with particular areas of the world. This unit will only play discs that have compatible region codes. You can find the region code of your unit by looking on the rear panel. Some discs are compatible with more than one region (or all regions).

Sampling frequency

The rate at which sound is measured to be turned into digital audio data. The higher the rate, the better the sound quality, but the more digital information is generated. Standard CD audio has a sampling frequency of 44.1kHz, which means 44,100 samples (measurements) per second. See also Digital audio.

Slideshow (DVD, Super VCD/Video CD) A feature of some DVD discs in which still pictures recorded on the disc cycle automati- cally as the audio is played. See also Browsable pictures.

Title (DVD-Video only)

A collection of chapters on a DVD-Video disc. Equivalent to a DVD-Audio group. See also Chapter and Group.

Track

Audio CDs, Super VCDs/Video CDs and DVD-
Audio discs all use tracks to divide up the
content of a disc. The DVD-Video equivalent is
called a chapter. See also Chapter and Group.	61
