Glossary
ARC (Audio Return Channel)
This function was added to HDMI Ver.1.4.
This sends digital audio signals from the HDMI input terminal of the TV, etc. to the HDMI output terminal of this system.
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 system can reproduce greater color gradation (4096 steps) when connected to a compatible TV and recorder, etc.
You can enjoy exceptionally rich,
Dolby Digital
Digital sound compression technology developed by Dolby Laboratories.
Compatible with surround sound as well as
Dolby Pro Logic
This system can process not only Dolby Surround, but also other
Dolby Virtual Speaker
This system allows you to enjoy a surround effect with two front speakers. This is not merely a “virtual surround” effect, but rather uses the optimal speaker arrangements and listening positions for
Down-sampling
This is the process of resampling by reducing the sampling rate of a signal that was sampled at a certain rate.
DTS (Digital Theater Systems)
Surround system used in most movie theaters. Separation works well between channels, resulting in realistic surround effects.

Optical
Using an optical fiber cable for digital signal input/output from DVD, CD, etc., provides better sound quality for playback or recording compared to analog. Only possible with equipment that has an optical terminal.
PCM (Pulse Code Modulation)
This is one of the methods that enable analog sounds to be converted to digital sounds without compression.
This method is used for music CD, etc.
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.
Standby through function
When this system and the TV and
Images recorded with x.v.Color or Deep Color are also supported.
Surround signal
Audio signal made up with front speakers, center speaker and surround speakers. For this system, surround signal is automatically played by Dolby Virtual Speaker.
WHISPER-MODE SURROUND
Even when the sound volume level is low, you can enjoy dynamic surround playback similarly as during normal playback. This is convenient when listening at night.
x.v.Color
This is a name of products compliant with ISO Standard for wider color space: “xvYCC”. This system supports x.v.Color.
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. This system supports 1080p.
5.1-channel surround
Monaural and stereo use one channel and two channels respectively to reproduce sound, but
7.1-channel virtual surround
