Abstract
Methods for the real-time, reversible compression of high dynamic range videos, allowing high dynamic range videos to be broadcast through standard dynamic range channels. The methods include streaming pixel values from at least one image sensor through a pipeline on a processor. The pipeline includes an HDR function that combines the streaming pixel values in real-time into an HDR stream and a transfer function that converts the HDR stream to an SDR video stream. The method further includes transmitting the SDR video stream to a receiver in real time for display as a video.
