Bit Stream

A signal that is compressed and changed into digital format. Then depending on the decoder it can be processed as 5.1 multi-channel audio.

By using 2-channel stereo for the surround speakers, more accurate moving sound effects and surround sound environment can be reproduced, like the rustling of trees or sound of waves.

Channel (ch)

A channel is an audio type that has been divided based on range and other characteristics.

E.g. 5.1 channel

•Front Speakers, Left (1ch), Right (1ch)

•Center Speaker (1 ch)

•Surround Speakers, Left (1ch), Right (1ch)

•Subwoofer (1 ch x 0.1* = 0.1 ch)

*In contrast to a full 1-channel band, a component designed to enhance low frequency sound for added effect.

Cinema DSP (Digital Sound Field Processor)

Dolby Surround and DTS were originally designed for the movie theater, so playing the same program at home would produce disparate listening experiences depending on variables like the room size, walling and number of speakers.

Yamaha Cinema DSP applies original sound field technology based on a wealth of real-world data measurements to reproduce Dolby Pro Logic, Dolby Digital and DTS sound, combining them with acoustic scale, depth and tone so that you can experience the presence of a movie theater at home.

Component Video Signal

A component video signal is separated into one luminance Y-signal and two chrominance PB/CB and PR/ CR signals. Since each signal is sent independently, color can be reproduced more faithfully. The component signal is also called a color-difference signal by the way it subtracts the luminance signal from the color signals.

Decoder

A device that converts encoded data on DVD and other media back to its original audio or video signal.

Dolby Digital

Dolby Digital is a digital surround sound system that gives you completely independent multi-channel audio. With 3 front channels (left, center, and right), and 2 surround stereo channels, Dolby Digital provides 5 full- range audio channels. With an additional channel especially for bass effects, called LFE (low frequency effect), the system has a total of 5.1 channels.

Dolby Pro Logic

Asurround system that takes a 4-channel signal and records it as a 2-channel signal, then by way of some arithmetic processing converts back to an independent 4- channel signal for playback.

Dolby Pro Logic II

Takes any 2-channel source and reproduces dynamic

5.1-channel surround with excellent separation using special signal processing. You can experience Dolby Pro Logic II in MOVIE mode and MUSIC mode for stereo. You can even enjoy old movies that were only recorded in 2-channel audio (excluding monaural) in powerful 5.1-channel surround.

DTS (Digital Theater Systems)

The 5.1-channel surround system adopted by most movie theaters. With an abundance of audio data, it is able to provide authentic sounding effects.

Dynamic Range

The difference between the smallest sound that can be heard above the equipment noise and the biggest sound that can be heard without distortion is the dynamic range.

Film and Video Data

In general, DVD media can be classified into the 2 types below.

•Film Data

Video recorded at 24 frames/second. (The film used for shooting movies is recorded at 24 frames/second.) Recently 30 frames/second progressive video has made its debut.

•Video Data

Video recorded at 30 frames/second.

CinemaStation will automatically recognize whether the source recorded on DVD is film or video, then select the best method to convert it into progressive output.

Interlace and Progressive Outputs

Up to now the standard video signal has been NTSC with 525i (i: interlaced) scan lines. In contrast, 525p (p: progressive) is a high-density signal with double the number of scan lines.
