Subjectively weighted noise measurement
View Patent ↗Subjectively weighting noise measurements for multiple video formats based upon a defined standard for a standard definition video format uses a ratio between the active line time for the standard definition video format and the active line time for another video format to be measured in order to rescale a unified weighting filter for the standard definition video format for the another video format.
1. A method of subjectively weighting noise measurement for multiple video formats based on a defined filter specification of insertion loss versus frequency for a standard definition video format comprising the steps of:
determining a ratio between an active line time for the standard definition video format and an active line time for another video format; and
rescaling a unified weighting filter for the standard definition video format using the ratio to adapt the unified weighting filter for the another video format.
