Pioneer DV-989AVi-S Pqls Precision Quartz Lock System rate control, Progressive scan video

09Additional information

PQLS (Precision Quartz Lock System) [rate control]

Technology for high-precision transmission of digital audio over the i.LINK interface enabling jitterless digital-to-analog conver- sion using a precision quartz in the rate control-compatible receiver.

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. See also About progressive scan video on page 24.

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. Stan- dard CD audio has a sampling frequency of 44.1kHz, which means 44,100 samples (measurements) per second. See also Digital audio.

Slideshow (DVD, Video CD/Super VCD)

A feature of some DVD discs in which still pictures recorded on the disc cycle automati- cally as the audio is played. See also Brows- able Picture.

Regions (DVD-Video only)

These associate discs and players with partic- ular 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).

S1 S-video output

This S-video signal format includes aspect ratio information (4:3 or 16:9) within the video signal. TVs which are compatible with S1 S- video automatically switch aspect ratio according to the signal.

S2 S-video output

S2 is an enhanced version of S-video which, in addition to aspect ratio information, contains letterbox / pan & scan information. Wide- screen TVs which are compatible with S2 S- video automatically switch aspect ratio according to the signal.

Super Audio CD (SACD)

Super Audio CD is a high quality audio disc format that can accommodate high sampling rate stereo and multi-channel audio, as well as conventional CD audio all on the same disc.
