A method for blending video data with graphics data in a video receiver, the method comprising: receiving input video data and input dynamic metadata for the input video data, wherein the input video data is at a video dynamic range; receiving input graphics data at a graphics dynamic range different from the video dynamic range; receiving display identification data from a target display to which the video receiver is linked over a video interface; generating, based at least in part on the input dynamic metadata, the display identification data, and a numeric interpolation factor, interpolated dynamic metadata, which specifies a source dynamic range that has a maximum luminance interpolated between a maximum luminance of the video dynamic range and a maximum luminance of the target dynamic range; generating tone-mapped video data of the source dynamic range from the input video data of the video dynamic range by mapping the video dynamic range of the input video data to the source dynamic range specified in the interpolated dynamic metadata; generating mapped graphics data of the source dynamic range from the input graphics data of the graphics dynamic range by mapping the graphics dynamic range of the input graphics data to the source dynamic range specified in the interpolated dynamic metadata; generating the graphics blended video data by blending the tone-mapped video data of the source dynamic range and the mapped graphics data of the source dynamic range based at least in part on the interpolated dynamic metadata sending the graphics blended video data and the interpolated dynamic metadata to the target display for rendering graphics blended images represented in the graphics blended video data, wherein the display identification data from the target display specifies a target dynamic range of the target display. receiving input video data and input dynamic metadata for the input video data, wherein the input video data is at a video dynamic range; receiving input graphics data at a graphics dynamic range different from the video dynamic range; receiving display identification data from a target display to which the video receiver is linked over a video interface; generating, based at least in part on the input dynamic metadata, the display identification data, and a numeric interpolation factor, interpolated dynamic metadata, which specifies a source dynamic range that has a maximum luminance interpolated between a maximum luminance of the video dynamic range and a maximum luminance of the target dynamic range; generating tone-mapped video data of the source dynamic range from the input video data of the video dynamic range by mapping the video dynamic range of the input video data to the source dynamic range specified in the interpolated dynamic metadata; generating mapped graphics data of the source dynamic range from the input graphics data of the graphics dynamic range by mapping the graphics dynamic range of the input graphics data to the source dynamic range specified in the interpolated dynamic metadata; generating the graphics blended video data by blending the tone-mapped video data of the source dynamic range and the mapped graphics data of the source dynamic range based at least in part on the interpolated dynamic metadata sending the graphics blended video data and the interpolated dynamic metadata to the target display for rendering graphics blended images represented in the graphics blended video data, wherein the display identification data from the target display specifies a target dynamic range of the target display.
