METHOD AND DEVICE FOR ACQUIRING EVENT DATA THAT RELATE TO PAST EVENTS

摘要

The invention relates to a device and a method for determining the absolute time or the absolute period of time of an event without performing a time measurement. For this purpose, the intervals of individual events are determined in such a manner that they form a code that allows conclusions as to the time or the period of time of the event. The individual events are for example transmitted by a television station to a television viewer. If the television viewer actuates a button or the like when the individual event occurs, he thereby simulates the code. The simulation of the code is stored and can be evaluated, thereby allowing conclusions as to what program the viewer watched at what time.
