X-Reality™ Engine for clear, vivid pictures

Blu-ray Disc™ movies, cable TV, satellite TV and even Web videos each place unique demands on the processing circuits of a TV. The X-Reality Engine helps get the best results from different video sources. The X-Reality Engine analyzes the scene and selectively applies three noise reduction processes prior to upscaling in order to get the best results from different sources.

  • Intelligent MPEG Noise Reduction dramatically reduces two common problems in compressed video signals - block noise and mosquito noise. Block noise occurs in fast-motion scenes where the picture appears to momentarily break up into little squares. Mosquito noise appears at the edges of high-contrast scenes, often making it appear that the on-screen objects are surrounded by a cloud of mosquitoes. Image
  • Adaptive Random Noise Reduction cleans up graininess caused by limitations of low-light performance in some video cameras. Image shot in very low light by a digital video camera can suffer from grainy, random noise that looks like snow. This picture noise is caused when the camera attempts to boost very weak electrical signals coming from the image sensor.
  • Adaptive Dot Noise Reduction corrects the dot crawl often found in old, composite video signals.

NOTE: The X-Reality Engine performs Interlace-to-Progressive (IP) conversion and upscaling as required. Film-based 24 frames-per-second content undergoes special IP conversion to reduce the stair-step (aka jaggies) that can form at high-contrast edges.

The X-Reality Engine also uses the Intelligent Image Enhancer to divide the signal according to four characteristics:

  • Texture
  • Outline
  • Contrast
  • Color

These characteristics not only influence our subjective impression of an image, they also have distinct mathematical properties. The circuit divides the picture into these four parts, analyzes the quality of each scene and applies only the processing required for each part. The result is a picture that's carefully optimized for natural image reproduction.

Flat Tone Area Adaptive Processing maintains image smoothness in areas of gentle gradation, such as sky and skin.
