Abstract:
A reception device is provided. The reception device includes a high definition multimedia interface configured to receive first video data of a first high dynamic range video and first characteristic information for an electro-optical conversion of the first video data, the first characteristic information including a first value for the electro-optical conversion of the first video data when a first high dynamic range curve is to be indicated and a second value for the electro-optical conversion of the first video data when a second high dynamic range curve is to be indicated. The reception device includes reception circuitry configured to receive second video data of a second high dynamic range video and second characteristic information for electro-optical conversion of the second video data. The reception device further includes a video decoder, electro-optical conversion circuitry, and a display.
