Abstract
A solution for adaptively processing a digital image with reduced color resolution is described herein. A source device pre-processes a video frame with reduce color resolution by remapping luma components and chroma components of the video frame, and encodes the pre-processed video frame. The source device remaps a half of luma components on a scan line of the video frame onto a data channel of a source line to an encoder and remaps the other half of the luma components on the scan line to another data channel of the source line. The source device remaps the corresponding chroma components onto a third data channel of a source line. By using a data channel conventionally configured to transmit chroma components, the solution enables a video codec to adaptively encode a digital image with reduced color resolution without converting the digital image to full color resolution before the encoding.
