Abstract: A device for multiple-quality level video processing includes a primary tap configured to receive prime-quality video content from a source and to provide the prime-quality video content to a primary path and to a secondary tap. The primary tap may be operable in a prime-quality mode. The secondary tap may be disposed after the primary tap and may be coupled to a number of secondary paths. One or more dithering modules may be disposed after the primary tap. The dithering module(s) may be configured to convert the prime-quality video content provided by the primary tap to lower-bit precision and/or lower pixel-rate video content for use in one or more of the secondary paths.
