demonstrates the usefulness of two of its upcoming switchers
at IBC: the Home Theater Scaler Plus and the HDMI Scaler.
Both enable the up/down scaling of high definition video signals
in all resolutions from 480i to 1080p while supporting the
embedded audio in the HDMI signal.
The Home Theater Scaler Plus, however,
is differentiated by its unique assortment of offerings. It
comes with four inputs in different formats: two HDMI, one
component with digital audio and one composite/s-video with
analog audio. It performs seamless source switching among
all four inputs, controlled by IR remote, allowing instant
access to multiple sources from the same display.
Component and composite/s-video inputs are
converted to the HDMI format with the audio embedded in the
same signal. This enables the plug and play connection of
different formats and an easy method of integrating old and
new equipment. A unique feature of this scaler is the independent
audio output in both analog mini-stereo and digital TOSlink
formats, alongside the HDMI audio/video output.
High definition resolutions can be tweaked
using the Home Theater Scaler Plus in order to achieve the
best imagery possible, including noise reduction, audio lip
synching and color correction features.
Gefen’s HDMI Scaler, on the
other hand, offers a simple system that can synchronize and
scale high definition resolutions from one HDMI source to
one HDMI display. It’s particularly useful when integrating
equipment with different native resolutions or achieving a
true 1080p output. It offers the same features for image quality
and refinement including color corrections, deinterlacing,
noise reduction and audio lip synching.
The ability to scale resolutions up and
down ensures a convenience method of securing pure high definition
video for a vibrant HDTV experience.
