By interpolating video data using proprietary algorithms, SD format data is up-converted to 1080 x 1920p HD format video data. This conversion to HD format increases the richness of the original data by approximately six fold, and produces the highest possible image quality when viewing content on a large-screen HDTV. The DVB-T Adaptive Noise Reduction detects and removes the block noise that is unique to digital broadcasts. It helps deliver beautiful, noise-free pictures. The DMR-EZ48V is Deep Color ready, which means they can reproduce images with 12-bit, 4,096-step gradation. You enjoy exceptionally rich, natural-looking colors, with smooth, detailed gradation and minimal color banding. The TV must also be Deep Color compatible. Other TVs will display 8-bit, 256-step gradation.
