Audio and video synchronization (lip sync)
Lip sync, an abbreviation for lip synchronization, is a
technical term that involves both a problem and a
capability of maintaining audio and video signals
synchronized during post-production and transmission.
Whereas the audio and video latency requires complex
end-user adjustments, HDMI version 1.3 incorporates an
automatic audio and video syncing capability that allows
devices to perform this synchronization automatically and
accurately without user interaction.
■ Bi-amplification connection
A bi-amplification connection uses two 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. The internal crossover of the
speaker consists of a LPF (low pass filter) and a HPF (high
pass filter). As its name implies, the LPF passes
frequencies below a cutoff and rejects frequencies above
the cutoff frequency. Likewise, the HPF passes
frequencies above its cutoff.
■ Component video signal
With the component video signal system, the video signal
is separated into the Y signal for 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 from 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
for 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
configuration can be freely selected for your enjoyment.
■ Dolby Digital EX
Dolby Digital EX creates 6 full-bandwidth output
channels from 5.1-channel sources. This is done using a
matrix decoder that derives 3 surround channels from the
2 in the original recording. 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 for high-definition programming and media
including HD broadcasts, HD DVD, and Blu-ray Disc.
Selected as a mandatory audio standard for HD DVD and
as an optional audio standard for Blu-ray Disc, this
technology delivers multichannel 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 for the optical disc players and AV receivers/
amplifiers of the future, Dolby Digital Plus also remains
fully compatible with the existing multichannel audio
systems that incorporate Dolby Digital.
■ Dolby Pro Logic II
Dolby Pro Logic II 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 for conventional Pro Logic
technology. There are three modes available: “Music
mode” for music sources, “Movie mode” for movie
sources and “Game mode” for game sources.
