Abstract
A system and techniques for converting a source image frame in a particular YUV format to another YUV format is presented. The system can include a texture component, a luminance component, and a chrominance component. The texture component can be configured to generate luminance input pixels and chrominance input pixels from the source image. The luminance input pixels can each include a luma component and the chrominance input pixels can each include a first chroma component and a second chroma component. The luminance component can be configured to generate luminance output pixels, where the luminance output pixels can each include a group of luminance input pixels. The chrominance component can be configured to generate chrominance output pixels, where the chrominance output pixels can each include a group of first chroma components or a group of second chroma components.
