Audio formats

Some audio formats used on discs are described below.

•Linear PCM

Uncompressed digital audio, the same format used on CDs and most studio masters.

DVD AUDIO supports up to six channels at sample rates of 48/96/192 kHz (also 44.1/88.2/176.4 kHz) and sample sizes of 16/20/24 bits.

DVD VIDEO supports two channels at sampling rates of 48/96 kHz and quantization of 16/20/24 bits.

Audio CD/Video CD limited to two channels, 44.1 kHz at 16 bits.

•MPEG Multichannel

A surround audio format which can handle the augmentative 7.1-channel format (rare for home use), as well as 5.1-channel.

•Dolby Digital

A surround audio format configured with six channels. Because the "LFE (Low-Frequency Effect for sub- woofer, etc.)" channel, one of the six channels, is an auxiliary channel, this format is called "5.1-channel system."

Not all Dolby Digital discs contain six (5.1) channel information.

•DTS (Digital Theater Systems)

A surround audio format configured with six (5.1) channels which is same as Dolby Digital. Because the compression ratio is lower than Dolby Digital, it provides wider dynamic range and better separation. Not all DTS discs contain six (5.1) channels information.

•MLP (Meridian Lossless Packing)

A format for DVD AUDIO with the compression ratio of about 2:1 while allowing the PCM signal to be completely recreated by the MLP decoder (required in all DVD AUDIO players). It supports up to 192 kHz/24 bit.

The associated indicator lights up in the display window when playing back a disc.

Indicator*	Audio format
LPCM	Linear PCM
MPEG	MPEG Multichannel
DOLBY DIGITAL	Dolby Digital
DTS	DTS (Digital Theater Systems)

*When playing back a DVD AUDIO disc recorded by MLP (Meridian Lossless Packing; a lossless audio compression system that can completely recreate the PCM signal), no indicator lights up in the display window.

Note that with some formats and/or depending on the unit’s [DIGITAL AUDIO OUTPUT] setting, digital audio signals may not be always transmitted from the unit’s DIGITAL OUT jacks as they are recorded on the disc.

See [DIGITAL AUDIO OUTPUT] on page 60 for details.
