The Benefits of HDTV Standard TVs (SDTVs) display a maximum of 480 lines using the interlaced scan method, which creates a picture with alternating lines of information. Enhanced-definition TVs (EDTVs) display a maximum of 480 lines using the progressive-scan method, which creates an image using consecutive lines of information for a crisp, flicker-free picture. High-definition TVs (HDTVs) display a maximum of either 1,080 interlaced lines or 720 progressively scanned lines for the sharpest possible image.

Total DSP (Digital Signal Processing) converts standard analog broadcast TV signals to digital and compensates for varying signal strengths, while the set's 8-bit, 20 MHz 3D Y/C comb filter removes blurred edges between colors and reduces dot crawl (tiny, moving dots of color along a sharp color separation in a vertical line, as in a depiction of a character's striped T-shirt). Velocity-scan modulation improves the definition at picture edges, creating sharper images by slowing the CRT (cathode-ray tube) beam's horizontal scanning during demanding work--say, when rendering transitions from light to dark parts of an image--and speeding it up when scanning easily rendered sections, like broad dark areas.

The TXN2798HF also offers 3:2 pulldown. DVD mastering introduces a common distortion when adjusting 24-frames-per-second movies to 30 fps video; 3:2 pulldown digitally corrects this distortion, removing the redundant information to display a film-frame-accurate picture. Samsung's DNIe Video Enhancer (or Digital Natural Image engine) enhances all analog NTSC and wideband video inputs for an overall improvement in picture quality. DNIe improves contrast, white level, and picture detail, incorporating digital noise reduction to improve low-quality video sources.

A shadow mask is a thin sheet of perforated metal behind the screen that restricts electron flow, each hole in the sheet corresponding to a single pixel. An Invar mask uses an alloy that's especially resistant to the high temperatures generated by the electron beam, allowing in a brighter, clearer picture. All onscreen information and menus appear in translucent overlays, letting you view video programs in the background while you consult the setup menus.

The set's two-tuner picture-in-picture with stock-ticker modes lets you monitor up to 13 different channels simultaneously. Stock-ticker mode places the lower one fifth of the screen of one channel into another channel so you can viewing streaming text beneath the program of your choice.

Other features include BBE High-Definition Sound (improves speech intelligibility and restores the dynamic range of compressed musical passages), V-Chip parental controls, and plug-and-play setup, which uses automation and a simple menu to select the source (broadcast or cable), set the clock, and map the active channels.

Inputs consist of a DVI-HDTV input for direct digital connection with a DTV receiver, dual high-definition DVD/DTV component-video inputs, an RF input (for an older VCR or cable box), three rear and one set of side-panel audio/video inputs (including one S-video input) to accommodate a camcorder, game console, or other sources. The set comes with a universal remote control.

More about DNIe
Digital Natural Image engine(DNIe) that could take a signal from any kind of source-not just conventional or high-definition digital broadcasting, but even DVD, Camcorder, PC and games-and turn it into a stunning picture on any kind of screen. The input signal passes through a series of four advanced processes that form the core of the DNIe technology.

The first of these processes, the Motion Optimizer, is responsible for noise reduction. the visual data are automatically broken down into signal and noise and analyzed through a combined spatial/temporal process. DNIe‘s noise reduction technology permits a startling level of sharpness even in minute details and rapidly changing scenes. Unlike conventional noise reduction methods, the Motion Optimizer combines a motion adaptive temporal filter, which detects and reduces noise in the temporal space between successive frames, with spatial noise reduction applied to the two-dimensional image space.

After passing through the Motion Optimizer,the visual signal is sent to the Contrast Enhancer. This process automatically adjusts contrast and brightness to natural levels, producing an extraordinarily rich and vivid picture. In scenes of motion or rapid change,a separate contrast value should ideally be set for each visual signal, but this presents great technological difficulties. DNIe’s Contrast Enhancer process has overcome these difficulties by applying over 1 million criteria for contrast and automatically determining the optimum contrast level for any kind of visual data. The Contrast Enhancer can also analyze up to 70,000 local images within a frame to preserve contrast in the smallest details without affecting overall color or brightness.

The next step in the signal's journey from input to high-quality output is the Detail Enhancer. DNIe's Detail Enhancer uses its own specially developed technology to dramatically improve sharpness just where it matters. The slightly unnatural appearance that results from conventional uniform detail enhancement is re-detected and re-adjusted to produce a strikingly sharp and convincing image. Conventional detail enhancement is based on the artificial amplification of the input signal, but this inevitably produces small areas of noise boost-up and flicker.

The final process undergone by the input signal is the Color Optimizer. For each scene, the Color Optimizer analyzes the hues of the input signal to determine and preserve the overall level of brightness. The colors are adjusted and improved, without unnatural intensification, to give vivid tones corresponding to the living shades of nature. By calculating the color saturation of red, green, and blue in each scene, the colors are optimized to the shades that the human eye accepts as natural.
