Digital Reality Creation FAQs
What is Digital Reality Creation (DRC)?
With the advent of the digital and multimedia era, Sony has recognized
the need to introduce Digital Reality Creation (DRC) technology into the
FD Trinitron WEGA line. This technology is capable of displaying high
quality images as well reproducing images that are realistic and high
in resolution.
DRC technology employs Sony's unique algorithm to recreate new
digital-like signals and replace conventional TV and video signals.
Using real-time processing, DRC reproduces a super-real image with
conventional TV signals, which has the picture quality similar to that
of a high definition picture signal.
What is DRC 1250?
DRC 1250 employs an original digital-signal processing algorithm that
doubles both the horizontal and vertical resolution, eliminating
virtually all visible scanning lines with a 400% Improvement in picture
density. By removing all visible scanning lines found in other
conventional TVs and doubling both the vertical scanning lines from 625
lines to 1250 lines and horizontal pixels from 720 pixels to 1440 pixels,
the resulting picture quality approaches that of a HDTV. DRC 1250
technology, coupled with Vertical Compression as with the Sony Wega ES
series, allows viewers to enjoy even better pictures with enhanced picture
density.
What is Vertical Compression technology?
Vertical Compression technology compresses a television image from 4:3
mode to 16:9 mode by focusing the scanning lines within the image area
and thus improving the picture quality. With this compression technique,
the lines of resolution that you would normally lose when viewing a
letterbox format image on a conventional size TV would be compressed into
the viewable area.
What is Virtual Dolby Digital?
With improved sound processing using the world's leading standard, Dolby
Digital algorithm, Sony created Virtual Dolby Digital. With only 2
speakers, Virtual Dolby Digital can emulate discrete 5.1 sound channels
(front left, front right, back left, back right, center and subwoofer).
Coupling the DVD component terminals with the Digital Audio-in, Sony's
ES series Digital Coaxial audio input allows maximum sound performance.
What is FD Trinitron?
Usually, the flatter the panel, the higher the chances of structural
distortion. For the FD Trinitron, computer simulations were carried out to
determine the optimum glass thickness to minimize this problem. The resulting
fully flat, tempered glass CRT overcomes the problem of structural distortion
while remaining approximately the same weight and depth as a conventional CRT of
the same screen size.
The new flatter grille utilizes a high-level vibration control mechanism
and a color differentiation structure with a finer center pitch width. These
significantly improve the resulting picture resolution. Heat distortion causes a
discoloration of the screen image, otherwise known as a "doming effect". The
grille's stable vertical tension absorbs expanding heat energy, ensuring that
beams hit the correct spot on the phosphor and preventing color spill typical of
other systems.
Within the electron gun, the focal length has been optimized from 27mm to
35mm. This change increases the beam's cross angle, improving the focus by
approximately 20%. In addition, greater uniformity in focus is achieved over the
entire screen. The resulting size of the beam spot is 30% smaller than those
found in conventional electron guns. An extended interval between the pre-focus
and main lenses delivers crisper, sharper, more precise images.
The highly precise coil of the FD Trinitron is constructed with a larger
diameter which reduces color aberration and picture distortion around the edges
of the screen. The yoke improves focus uniformity by an impressive 30% across
the whole screen, assuring sharpness from corner to corner.
