When speaking of HDR, it is – to put it simply – about the representation of an extended contrast range that approaches the human sense of sight. Impressively realistic images that we are familiar with from photography can now also be created with video. Until just a few years ago neither the camera technology nor playback devices were able to accomplish this. Today’s (above all digital cinema) cameras can capture the required dynamic range (c. 13-14 f-stops) and thus form the foundation for HDR. The standardisation committees mainly discuss two approaches to HDR for broadcast operations. The specifications of the UHD-compatible Blu-ray disc were published in mid-2015 and are already committed to the PQ (Perceptual Quantizer) approach based on SMPTE ST2084. The first TV sets supporting HDR in a standardised form are now successively coming to market. For playback on traditional devices, however, a conversion of the signal is required. The second approach, which was developed in cooperation between BBC and NHK, is called Hybrid Log Gamma. The advantage of this modified gamma curve is that both traditional and HDR-compatible television sets can process the signal and display the image without the need for conversion. The decision about which approach will win in the end will be made in the coming months.
