Abstract

Apparatus for displaying first and second information signals includes detection circuitry for detecting the first and second signals to be displayed as well as detecting the occurrence of a predetermined phenomenon with respect to the first information signal. The first and second information signals are processed in conjunction with a timing signal to provide a display signal, wherein the display signal is adapted to be displayed using known display circuitry. Detection of the predetermined phenomenon provides an interrupt to the processing of the information signals such that the occurrence of the predetermined phenomenon can be recorded, in time correlation with the occurrence of the first and second information signals. The information signals are thereafter processed so that the ocurrence of the predetermined phenomenon can be displayed in time correlation with either the first or second information signal.
