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.

Abstract translation: 用于多质量级视频处理的设备包括被配置为从源接收质量优质的视频内容并且将主质量视频内容提供到主路径和次级抽头的主分接头。 主抽头可以在主质量模式下操作。 次级抽头可以设置在主抽头之后并且可以耦合到多个次级通道。 一个或多个抖动模块可以在主抽头之后设置。 抖动模块可以被配置为将由主抽头提供的素质视频内容转换为低位精度和/或较低像素速率视频内容，以用于一个或多个次要路径。
