A video distribution system transfers a formatted video signal (20) having elementary streams representing audiovisual content to be rendered in a selected combination and stream information indicative of selectable elementary streams. The formatted video signal represents extended video having an extended range (HDR) of brightness and/or color. A video device (21) processes input video to provide video processing metadata representing a conversion between standard video and the extended video. The formatted video signal comprises a primary video elementary stream representing standard or extended video, a video processing elementary stream not comprising audiovisual content but comprising video processing metadata representing a conversion between standard and extended video or vice versa, and extended stream information comprising an entry indicative of the video processing elementary stream. Advantageously a video player (22), for example a BD player, is enabled to render both extended and standard video based on the extended stream information and the video processing elementary stream. |
