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, natural-looking colors, with smooth, detailed gradation and minimal color banding.
Dolby Digital
Digital sound compression technology developed by Dolby Laboratories.
Compatible with surround sound as well as 2-channel stereo sound. With this technology, you can keep massive amount of audio data in a disc efficiently.
Dolby Pro Logic 
This system can process not only Dolby Surround, but also other 2-channel sources to produce a 5.1-channel sound for a more realistic sound field. It is also possible to enhance old movies recorded in stereo with this dynamic 5.1-channel sound. This system uses Dolby Pro Logic 
to add surround effects to stereo sources such as video cassettes and CDs.
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 5.1-channel sound.
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.

| | Dynamic range is the difference between the lowest level of |

| 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.
Troubleshootingand | other information | Multi-channel LPCM (Linear PCM) |
This is the uncompressed audio signal encoded digitally. Multi- |
channel LPCM signals used for Blu-ray Disc, DVD audio, etc. |
offer playback with higher-sound quality. |
Up to 7.1-channel LPCM signals can be input to this system. |

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 Blu-ray Disc player/DVD recorder etc. are connected with HDMI cables, image/audio from Blu-ray Disc player/DVD recorder etc. can still be transmitted to the TV through this system even though the system is turned off. This is useful when you want to enjoy late night viewing only with the television speakers.
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 5.1-channel surround uses 5 speakers and 1 subwoofer. The 5 channels are: 1 center speaker, 2 front speakers, and 2 surround speakers at the side of or to the rear of the sitting position. Sound output of the subwoofer is much narrower than the other speakers, and so is considered as 0.1. This is called 5.1-channel surround when played through all 5.1 channels, and with this system you can achieve a similar effect with Dolby Virtual Speaker.
7.1-channel virtual surround
When playing back 7.1-channel LPCM signals with this function, you can enjoy wider sound field effects as if another speaker is added.
