Abstract:
A video timing display for multi-rate systems allows a user to quickly, easily and precisely measure the timing difference between video signals of different rates. A graphic display area within a raster display region provides a display of vertical and horizontal timing offsets of one video signal with respect to another video signal as a reference having a different frame rate. The graphic display area includes a reference indicator associated with the reference and timing indicators indicating the timing phases between the video signals, with one of the timing indicators being emphasized. A numeric display area may be provided adjacent the graphic display area to display the actual vertical and horizontal timing differences in appropriate units for the emphasized timing indicator relative to the reference indicator with a precision to one video clock cycle.
