ABSTRACT:
A video processing device may comprise one or more processors and/or circuits for use in a video processing device, in which the one or more processors and/or circuits may comprise a video scaler, a memory, a scaler engine, a clock selection circuit. The one or more processors and/or circuits are operable to receive a video image and select a video input clock or a display output clock for upscaling the received video image, or select the video input clock or the display output clock for downscaling the received video image based on a determination of whether the video image is to be downscaled or upscaled. The one or more circuits may be operable to downscale the received video image to generate a first scaled video image, and/or upscale the received video image to generate a second scaled video image, based on the selection.
