1. A method for streaming video for high dynamic range (HDR) and low dynamic range (LDR) display, the method comprising:
receiving frame-independent streams of pixel values from multiple image sensors onto a processing device in an HDR video camera;
streaming the pixel values through a pipeline on the processing device, wherein the pipeline includes a synchronization module that synchronizes the streams of pixel values, a kernel operation that identifies saturated pixel values, and a merge operation that merges the pixel values thereby producing an HDR signal;
tone-mapping the HDR signal to produce an LDR signal;
subtracting the LDR signal from the HDR signal to give a residual signal; and
transmitting an output signal comprising the LDR signal and the residual signal wherein the output signal is displayable as an 8-bit video by an LDR display, and displayable as HDR video by an HDR display.
