Glossary

Analog

Audio signals produced from L/R audio output terminals of general equipment is called analog audio.

CPPM (Content Protection for Prerecorded Media)

This is the copyright protection technology which prevents file copy of DVD audio.

Decoder, Decode

Decoder is the device to enable us to hear audio data that is encoded on DVD, etc., as a normal audio signal. This process is called Decode.

Deep Color

This unit incorporates HDMI™ (V.1.3 with Deep Color) technology that can reproduce greater color gradation (4096 steps) when connected to a compatible TV.

You can enjoy exceptionally rich, natural-looking colors, with smooth, detailed gradation and minimal color banding.

[A lower color gradation (256 steps), without deep color, will be reproduced if connected to a TV which does not support deep color.]

Digital

DVD recorders, Blu-ray Disc/DVD players, and CD players are usually equipped with digital output terminals. Connect through the digital terminal to enjoy digital surround systems such as Dolby Digital and DTS.

Dolby Digital

Digital audio compression technology developed by Dolby Laboratories, Inc. Compatible with surround sound as well as 2-channel stereo sound. With this technology, you can keep massive amount of audio data efficiently.

Dolby Digital +

Improved version of Dolby Digital. It offers higher-audio quality, support for multi-channel (5.1-channel and more) and increased bitrates.

Dolby Digital Surround EX

Improved version of Dolby Digital. You can playback 6.1-channel sound by adding surround center to 5.1-channel compatible with Dolby Digital.

Dolby Pro Logic /Dolby Pro Logic x

This technology converts any 2-channel source recorded including Dolby surround into 5.1/7.1 or 6.1-channel sound with more realistic sound effects. You can enjoy old movies recorded in conventional 2-channel sounds (excluding monaural sounds) as they are converted to dynamic 5.1/7.1 or 6.1-channel sound.

Dolby TrueHD

Dolby TrueHD is an advanced version of MLP lossless method used for DVD audio. This is a high-quality audio method which enables complete playback of audio data made through a mastering studio.

Dolby TrueHD can only be used for Blu-ray Disc, etc, but is not applicable to DVD audio format.

DTS (Digital Theater Systems)

Surround system used in most movie theaters. Separation works well between channels, resulting in realistic surround effects.

DTS 96/24

This is higher-quality DTS with 96 kHz/24 bit and used for DVD-Video. 48 kHz/24 bit playback is possible on systems incompatible with DTS 96/24 due to backward compatibility.

52

DTS-ES

Improved version of DTS. You can playback 6.1-channel sound by adding surround center to 5.1-channel.

DTS-HD

Audio technology enhanced in sound quality and functions based on DTS (used at movie theaters). You can playback DTS-HD sound as DTS on conventional AV amplifiers due to backward compatibility.

Depending on the encoding methods and bitrates, DTS is classified into three types: DTS-HD Master Audio, DTS-HD High Resolution Audio and DTS Digital Surround.

The format itself supports up to 2048 channels, but the maximum number of channels for next-generation DVD (Blu-ray Disc, etc.) is 8ch (7.1ch).

Dynamic range

Dynamic range is the difference between the lowest level of sound that can be heard above the noise of the equipment and the highest level of sound before distortion occurs.

HDMI (High Definition Multimedia Interface)

HDMI enables you to transmit digital audio and video signals using a single cable.

You can also transmit control signals using HDMI connections.

LPCM (Linear PCM)

This is one of the PCM methods and the uncompressed audio signal encoded digitally. This method is used for music CD, etc. Multi-channel LPCM signals used for Blu-ray Disc, DVD audio, etc. enable playback with higher-sound quality.

Optical

Using optical fiber cable for digital signal input/output from DVD, CD, etc., provides better sound quality for playback or recording compared to analog.

PCM (Pulse Code Modulation)

This is one of the methods that enables analog sounds to be converted to digital sounds.

Sampling frequency

Sampling is the process of converting the heights of sound wave (analog signal) samples taken at set periods into digits (digital encoding).

Sampling frequency is the number of samples taken per second, so larger numbers mean faithful reproduction of the original sound.

Surround signal

Audio signal made up with front speakers, center speaker and surround speakers.

x.v.Color

This is a name of products compliant with ISO Standard for wider color space: “xvYCC”.

1080p

This is one of the digital hi-vision images.

1080 is the number of effective scanning lines that constitute the actual screen. This enables every detail to be beautifully expressed. Images are less flickered with progressive method that scans in order from the top.
