Claim 0:
1. A method comprising:
receiving a medium dynamic range video signal and metadata associated with the medium dynamic range video signal, the metadata including data representative of a peak luminance value of the medium dynamic range video signal;
receiving data representative of a peak luminance value of a presentation display;
determining whether the peak luminance value of the medium dynamic range video signal is greater or lower than the peak luminance value of the presentation display; and
processing the medium dynamic range video signal in a first mode if the peak luminance value of the medium dynamic range video signal is greater than the peak luminance value of the presentation display and in a second mode if the peak luminance value of the medium dynamic range video signal is smaller than the peak luminance value of the presentation display, wherein a variable included in the metadata has a data value representing the second mode to specify that a high dynamic range video signal has been pre-processed according to the second mode to generate the medium dynamic range video signal.
