Abstract
A structure outputting a decoded video stream includes a processing block and a range modification circuit. The processing block decodes an input stream to generate and store a decoded stream in a decoded picture buffer, wherein the decoded stream comprises a luminance component and a chrominance component a decoded stream. The range modification circuit receives the decoded stream, and modifies, if required, a luminance range of the luminance component and a chrominance range of the chrominance component. The range modification circuit further outputs a video stream. The video stream comprises the modified luminance component when the luminance modification signal is true, and the video stream comprises the luminance component when the luminance modification is false. Similarly, the video stream comprises the modified chrominance component when the chrominance modification signal is true, and the video stream comprises the chrominance component when the chrominance modification signal is false.
