Yamaha RX-V1065 Audio and video synchronization lip sync, Bi-amplification connection, Deep Color

•Audio and video synchronization (lip sync)

Lip sync, an abbreviation tbr lip synchronization, is a technical term

that involves both a problmn and a capability of maintaining audio and

video signals synchronized during post-production and transmission. Whereas the audio and vkteo latency requires complex end-user

adjustments, HDMI version 1.3 incorporates an automatic audio and video syncing capability that allows devices to pert_rm this

synchronization automatically and accurately without user interaction.

•Bi-amplification connection

A bi-amplifcation connection uses t,a,o amplifiers for a speaker. One amplifier is connected to the woofer section of a loudspeaker while the other is connected to the combined mid and tweeter section.

With this arrangement each amplifier operates over a restricted frequency range. This restricted range presents each amplifier with a much simpler job and each amplifier is less likely to influence the sound in some way.

•Component video signal

With the component video signal system, the video signal is separated into the Y signal t_r the luminance and the PB and PR signals for the

chrominance. Color can be reproduced more faithfully with this

system because each of these signals is independent. The component signal is also called the "color difference signal" because the luminance signal is subtracted from the color signal. A monitor with

component input jacks is required in order to output component signals.

•Composite video signal

With the composite video signal system, the video signal is composed of three basic elements of a video picture: color, brightness and

synchronization data. A composite video jack on a video component transmits these three elements combined.

•Deep Color

Deep Color refers to the use of various color depths in displays, up t_om the 24-bit depths in previous versions of the HDMI specification.

This extra bit depth allows HDTVs and other displays go from millions of colors to billions of colors and eliminate on-screen color

banding t_r smooth tonal transitions and subtle gradations between colors. The increased contrast ratio can represent many times more shades of gray between black and white. Also Deep Color increases the number of available colors within the boundaries defined by the RGB or YCbCr color space.

•Dolby Digital

Dolby Digital is a digital surround sound system that gives you

completely independent multi-channel audio. With 3 front channels (front L/R and center), 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 (LFE is counted as 0.1 channel). By using 2-channel stereo for the surround speakers, more accurate moving sound effects and surround sound environment are possible than with Dolby Surround. The wide dynamic range from maximum

to minimum volume reproduced by the 5 full-range channels and the

precise sound orientation generated using digital sound processing

provide listeners with unprecedented excitement and realism.

With this unit, any sound environment from monaural up to a 5.1-

channel confguration can be freely selected for your enjoyment.

•Dolby Digital Surround EX

Dolby Digital EX creates 6 full-band'addth output channels from 5. l- channel SOUrCes.

For the best results, Dolby Digital EX should be used with movie sound tracks recorded with Dolby Digital Surround EX. With this additional channel, you can experience more dynamic and realistic

moving sound especially with scenes with "fly-over" and "fly- around" effects.

•Dolby Digital Plus

Dolby Digital Plus is an advanced audio technology developed t_r

high-definition programming and media including HD broadcasts, and Blu-ray Disc. Selected as an optional audio standard t_r Blu-ray

Disc, this technology delivers nmltichannel sound with discrete channel output. Supporting bitrates up to 6.0 Mbps, Dolby Digital Plus can carry up to 7.1 discreet audio channels simultaneously. Supported by HDMI version 1.3 and designed t_r the optical disc

players and AV receivers!amplifiers of the flmlre, Dolby Digital Plus

also remains fully compatible with the existing multichannel audio systems that incorporate Dolby Digital.

•Dolby Pro Logic II

Dolby Pro Logic I] is an improved technique used to decode vast numbers of existing Dolby Surround sources. This new technology enables a discrete 5-channel playback with 2 front left and right channels, 1 center channel, and 2 surround left and right channels

instead of only 1 surround channel t_r conventional Pro Logic technology. There are three modes available: "Music mode" t_r nmsic sources, "Movie mode" for movie sources and "Game mode" t_r

gallle sources,

•Dolby Pro Logic IIx

Dolby Pro Logic lIx is a new technology enabling discrete

multichannel playback from 2-channel or nmlti-channel sources. There are three modes available: "Music mode" for music sources, "Movie mode" for movie sources (for 2-channelsources only) and "Game mode" for game sources.

•DolbySurround

Dolby Surround is widely used "a,ith nearly all vkteo tapes and laser discs, and in many TV and cable broadcasts as well. Dolby Surround uses a 4-channel analog recording system to reproduce realistic and dynamic sound effects: 2 l_ont left and right channels (stereo), a center channel for dialog (monaural), and a surround channel t_r special sound effects (monaural). The surround channel reproduces sound within a narrow frequency range. The Dolby Pro Logic decoder built into this unit employs a digital signal processing system that

automatically stabilizes the volume on each channel to enhance moving sound effects and directionality.

•Dolby TrueHD

Dolby TrueHD is an advanced lossless audio technology developed

for high-definition disc-based media including Blu-ray Disc. Selected as an optional audio standard for Blu-ray Disc, this technology delivers sound that is bit-for-bit identical to the studio master, offering

a high-definition home theater experience.

Supporting bitrates up to 18.0 Mbps, Dolby TrueHD can carry up to 8 discrete channels of 24-bit/96 kHz audio simultaneously.

Dolby TrueHD also remains fully compatible with the existing multichannel audio systems and retains the metadata capability of

Dolby Digital, allowing dialog normalization and dynamic range control.
