|Sony's 1920 x 1080 display is naturally able to resolve finer details than the typical TV. (Simulated Picture for Illustration.) |
BRAVIA XBR television was designed from the ground up to deliver the best of High Definition. For the larger screen sizes, this means not only HDMI inputs with 1080p signal capability but also a full HD panel resolution of 1920 pixels horizontal x 1080 pixels vertical.
This amounts to over 2 million pixelsresolution that plasma panels are hardpressed to match, especially in 40 and 46-inch diagonal screen sizes. Sony's 2 million pixels are more than twice as many as 720p plasma HDTVs and more than five times that of plasma EDTVs. The difference is profound. For example, in order to show 1080i or 1080P High Definition signals, a 720P television must first downconvert the signal, losing more than 55% of the pixels in the process! BRAVIA XBR television's Full HD 1080 design delivers every pixel of performance from HD sources.
What is Picture Quality?
|QUESTION: Which is responsible for picture quality? ANSWER: All of them. (Simulated Picture for Illustration.) |
For some TV manufacturers, Full HD resolution would be enough. But for the Sony XBR® Series, native 1920 x 1080 resolution is only the beginning. Sony engineers demanded all the other attributes of an outstanding television picture, including high contrast, superb color fidelity, natural gradation from dark to light, and excellent clarity. Sony BRAVIA XBR televisions deliver the total picture.
Where Does Picture Quality Come From?
Thanks to Sony's unsurpassed television expertise, we understand that almost every part of an LCD television can enhanceor deterioratethe final picture. For Sony, having a superlative LCD panel is only a starting point. Sony XBR televisions also boast the right inputs, advanced signal processing, an innovative backlight, enhanced color filters and a low-glare screen. We will look at each of these picture quality components in turn.
HDMI 1080p inputs
While signal inputs may not make your heart beat faster, they have a profound effect on picture quality. Over the last 20 years, each new generation of video connections has enabled a marked improvement in home video picture quality. That's why the larger screen sizes of BRAVIA XBR® television include three High Definition Multimedia Interface (HDMI) digital audio/video inputs, each with up to 1080p capability.
|A single HDMI connection can carry uncompressed component digital video and uncompressed digital audio. |
- 1080p capability. These connections are compatible with some of the most advanced and soon to be released home video sources on the planet: Blu-ray Disc players and the PLAYSTATION®3 game console. These sources can exceed the performance of over-the-air HDTV broadcasts. In this way, you'll enjoy the latest and best that HD sources have to offer.
- Digital video. To preserve every nuance of your HD signal, the HDMI connection carries uncompressed digital video of the highest quality.
- Digital audio. Unlike the Digital Visual Interface (DVI) system, the HDMI connection also carries digital audio, including uncompressed digital audio.
- Three HDMI inputs. BRAVIA XBR models include three HDMI inputs to accommodate a set-top box, Blu-ray Disc player and PLAYSTATION®3 game console simultaneously.
BRAVIA Engine Pro circuitry
In a modern flat panel television, the video processing circuitry performs vital functions, all of which have an impact on picture quality. To maximize every last bit of picture information, BRAVIA XBR televisions incorporate the BRAVIA Engine Pro full digital video processing system. This preserves the signal in the digital domain, avoiding unnecessary video degradation. The system includes four stages.
To maximize picture quality, the BRAVIA Engine Pro full digital video system conducts four stages of processing in the digital domain.

- Composite-to-Component Processor XA (CCP-XA). Even the latest HDTV must still accommodate old-style analog composite video input signals. Sony's CCP-XA circuit converts incoming composite video into component signals with wide bandwidth and rock-solid stability. Three dimensional video signal analysis yields excellent Y/C comb filtering and reduces the flecks and specks of pixel-level noise, as well as block noise and "mosquito" noise. The CCP-XA also yields extremely smooth color gradation, giving richer, more realistic skin tones.
- Digital Reality Creation Multifunction version 2.5 circuit (DRC MF v2.5). As broadcast and packaged media shifts from SDTV to HDTV, televisions must accommodate a wide range of signal formats. These include 480i, 480p, 720p, 1080i and 1080p. Sony's native 1920 x 1080 resolution means that these televisions never need to downconvert and throw away pixel data. It also means that any signal that does not originate as 1080p must first be upconverted. Sony's proprietary Digital Reality Creation circuit performs this crucial function.
Unfortunately, upconversions are notoriously difficult, as they attempt to turn a lower-resolution input into a higher-resolution output. Some televisions merely "connect the dots" with interpolation, ending up with a soft picture of higher resolution. Sony demanded more. Our proprietary Digital Reality Creation (DRC) circuitry analyzes the lower-resolution input signal in real-time, and then determines what that signal would have been, if it had originally been an HD signal. In this way, DRC circuitry can generate resolution that wasnt present in the original signal. The result is quality that conventional interpolation has a much more difficult time achieving: stunning detail approaching HD quality from SD sources.
There's more. Sony Full HD 1080 televisions with our BRAVIA Engine Pro system incorporate the DRC-MF version 2.5 circuit, with increased processing power compared to our previous designs. This extra horsepower means that the advantages of DRC-MF can now be applied not only to 480i (SD) sources, but also to 480p, 720p and 1080i sources. This yields more detail for a wider range of inputs. The circuit also includes an advanced mode, optimized for content that has previously been upconverted from SD to HD. Combining this advanced algorithm with our Interlace-to-Progressive (I/P) conversion, Sony's 1080p Direct Creation achieves a picture of spectacular quality.

|The DRC MF Palette on-screen control enables you to adjust the conversion according to the video source. Once you find the optimum setting, the television remembers your choice for each input. (Simulated Picture for Illustration.) |
- Image Format Processor 2 (IFP2). Sony's IFP2 circuitry establishes superb picture uniformity. A Digital Texture Enhancer optimizes the entire range of BRAVIA Final Page 8 contrast from dark to bright while improving picture clarity. Motion Vector Noise Reduction minimizes unwanted artifacts in moving subjects.
- Panel Driver. The final stage of the BRAVIA Engine Pro circuit, the Panel Driver optimizes the output signal for the specific requirements of Sony's LCD panel. Highly precise nonlinear video processing and color compensation enable reproduction of video images with vibrant blues, greens and whites, as well as superb dark-area detail.
The most advanced video processing block in the history of Sony television, BRAVIA Engine Pro circuitry lays the groundwork for all the picture enhancements that follow. It's only available in BRAVIA XBR television.
Live Color Creation System
By itself, an LCD panel cannot generate color. It can only pass or block light. The total available color depends on the backlight behind the LCD panel, while the final color is determined by a series of color filters in front of the LCD panel. Sony takes these elements a generation further with our Live Color Creation System, which delivers dramatically saturated, lifelike color. The system includes three distinct elements:
- Panel Driver. The last stage of the BRAVIA Engine Pro system, this circuit performs color space conversion tailored to the specific characteristics of Sony's Wide Color Gamut CCFL backlight.
Wide Color Gamut CCFL backlight. While others considered the cold cathode fluorescent light (CCFL) a "generic" part with no potential for improved performance, Sony saw an opportunity. Sony's Wide Color Gamut CCFL incorporates exclusive phosphor chemistry. The result: an improved phosphor spectrum for an expanded "gamut" or range of colors the television can express. The industry's first of its kind, the Wide Color Gamut CCFL is one big reason why Sony's BRAVIA XBR television can reproduce such gorgeous greens and deep, saturated blues.
|Compared to a conventional backlight (blue triangle), Sony's Wide Color Gamut CCFL (red triangle) produces far deeper, more saturated yellows and greens. |
- RGB Color filters. In the Full HD 1080 picture, the over 2 million pixels are all comprised of three sub-pixels, each filtered for Red, Green or Blue. An LCD television's gamut or range of reproduced colors is ultimately determined by the colorimetry of these filters. That's why Sony carefully matched the color filters in front of the LCD to the potential of the Wide Color Gamut CCFL behind the LCD. The result is the intense, vivid, true-to-life color that sets BRAVIA television apart.
Advanced Contrast Enhancer (ACE)
The CCFL backlight is remarkable for one other reason: the ability to vary the backlight, enhancing the perceived contrast. Contrast is the ratio between the brightest possible white and darkest possible black that a television can reproduce. Contrast is an essential tool of cinematographers and videographers, who use it to endow their source material with breathtaking impact.
|"Static" or "on-screen" contrast ratio measures the maximum contrast that can be on the screen at a given instant. Simulated Picture for Illustration.) |
Today's televisions are evaluated by two distinctly different types of contrast. "Static" or "on-screen" contrast is the ratio of the luminosity of the brightest white and the darkest black that a television can produce simultaneously on the screen. This is the truest measure of core performance. Sony BRAVIA XBR televisions achieve one of the highest On-Screen Contrast Ratios in LCD television: 1300:1.
"Dynamic" contrast ratio measures the luminosity of the brightest white and the darkest black the television can produce at two different instants in time. Sony's Advanced Contrast Enhancer (ACE) automatically senses the average picture level of the video signal and adjusts the intensity of the backlight accordingly. This increases the "dynamic" contrast ratio to 7000:1. You'll see better picture in night and day scenes, automatically. You can switch ACE on or off, according to your preference.
|"Dynamic" contrast ratio measures the maximum contrast that the television can generate over time. (Simulated Picture for Illustration.) |
Unfortunately, contrast specifications can be misleading. It is not always obvious whether a spec refers "static" or "dynamic" contrast. One manufacturer's measurements may not be directly comparable to another's. Your best guide is overall picture quality, as seen on a well-adjusted television, with a good signal source and appropriate room lighting.
7th Generation Sony LCD panel
A crucial component of any television is the part that makes the picturewhat engineers call the "display device." In the case of BRAVIA XBR® televisions, that device is a remarkable 7th Generation Sony LCD panel. LCD "generations" reflect the size of the mother glass from which each panel is cut. 7th Generation mother glass is substantially larger than previous generations. This enables Sony to deliver state-of-the-art picture quality at extremely attractive prices.
178 degree viewing angle. Plasma flat panels and conventional LCDs typically fall well short of the ideal viewing angle approaching 180 degrees. In contrast, Sony's 7th Generation panel has an internal Liquid Crystal structure that increases viewing angle to a phenomenal 178 degrees, so the picture remains vibrant when view ed from almost anywhere in the room.
|The picture from many previous LCD televisions deteriorates at extreme viewing angles (left). Sony BRAVIA XBR television delivers a vibrant picture over a 178 degree viewing angle (right). (Simulated Picture for Illustration.) |
|Slow response (left) can add unwanted blur to moving objects. Sony's 8-millisecond response (right) renders crisp, clear picture in many fact action scenes. (Simulated Picture for Illustration.) |
- Ultra-fast 8-millisecond response. The internal structure of Sony's LCD panel also promotes fast switching speed, important for picture clarity. Slow speed can add unwanted blur to fast-moving objects on the screen. This can be particularly noticeable when a bright object is moving against a dark background, or vice versa. Sony's fast, 8-millisecond switching speed keeps up with the world's most demanding video content. BRAVIA XBR televisions renders sports, action movies and video games with sharper, crisper and more lifelike motion.
Even a high-contrast television picture can be undone by something as simple as room lights or natural light coming through a window. In particular, these light sources can reflect off the television screen shining unwanted ambient light onto the screen. Plasma TVs are particularly susceptible to this glare effect. But Sony BRAVIA XBR televisions incorporate a screen that reduces reflection, preserving the quality of the picture.
Total picture quality
Sony's thorough approach to BRAVIA XBR® television goes far beyond any single feature or individual specification. Sony's total system method results in simultaneous improvements across the board, with 1920 x 1080 resolution, highimpact contrast, gorgeous color, seemingly effortless clarity and lifelike gradations of the most challenging subjects, such as skin tones. The result is a picture less like television, and more like a window on the world.
