09 Additional Information MPEG audio An audio format used on Video CDs and some DVD discs. This unit can convert MPEG audio to PCM format for wider compatibility with digital recorders and AV amplifiers. See also PCM. MPEG video The video format used for Video CDs and DVDs. Video CD uses the older MPEG-1 standard, while DVD uses the newer and much better quality MPEG-2 standard. Packed PCM (DVD-Audio only) A lossless compression system that enables more PCM audio to be stored on a DVDAudio 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) (Video CD only) A system of navigating a 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. See also page 19. 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). See also page 11. 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. See also page 55. S2 S-video output S2 is an enhanced version of S-video which, in addition to aspect ratio information, contains letterbox / pan & scan information. Widescreen TVs which are compatible with S2 S-video automatically switch aspect ratio according to the signal. See also page 55. 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. Slidshow (DVD, Video CD/Super VCD) A feature of some DVD discs in which still pictures recorded on the disc cycle automatically as the audio is played. See also Browsable Picture. Super Audio CD (SACD) Super Audio CD is a high quality audio disc format that can accomodate high sampling rate stereo and multi-channel audio, as well as conventional CD audio all on the same disc. 74 En
