摘要：
This application includes devices and methods for processing multimedia data to generate enhanced multimedia data at a receiver based on encoder assisted pre-processing. In one aspect, processing multimedia data includes identifying at least one pixel intensity range in at least one image of multimedia data, modifying at least a portion of the multimedia data to reduce the pixel intensity range, and encoding the modified multimedia data to form encoded multimedia data.
