FEATURE INFORMATION
As the digital era dawns, Hitachi has models that provide the best possible images today...and tomorrow. Our HDTV Ready
model incorporates new Flex Converter technology to display a high quality 1080i (high definition scanning) or 540P
(progressive scanning) image; this same circuitry enables it to accept a full 1080i HDTV signal from a digital set-top box now
or in the future.
FLEX CONVERTER TECHNOLOGY
With current analog broadcasts, there is just one level of picture quality. In the new age of digital TV, there will be several levels.
The highest, called HDTV, can be as high as 1080i.The next level, called HDTV, can be 720P. The standard level, SDTV, can
be 480P or 480i. Hitachi has developed the Flex Converter, advanced circuitry that allows your UltraVision UWX and SWX
series television to produce true 1080i HDTV resolution with an HDTV set-top box. It converts analog 480i signals to the
higher-quality 540P signals with no scan lines or flicker. The FDX and UDX needs a set-top box to receive any Digital Signal.
COMPONENT VIDEO
Component Video inputs accept separate blue, red & B/W signals from a high resolution digital source as DVD or digital set-
top box to provide a higher resolution picture.
3DYC (DIGITAL 3DYC COMB FILTER)
The Digital 3DYC Comb Filter analyzes three lines of information from a single video frame as well as lines from adjacent
frames. This technology eliminates the flickering that a detailed pattern or scene would normally cause, for the cleanest,
neatest picture possible.
PROGRESSIVE SCANNING
A standard TV uses Interlaced Scanning where each frame of video is broken into two fields, each providing alternating scan
lines. This can leave noticeable scan lines and cause flickering. With Progressive Scanning, complete frames are displayed for
a smoother picture with no scan lines and no flicker. This allows you to get the optimal picture quality from today s high
resolution digital sources such as DVD or a digital set-top box.
