Abstract

For determining the address, in terms of its respective longitudinal time code, of a selected video or other information signal recorded on a tape which has both longitudinal time codes and control pulses or control track signals recorded along its length, when the information signal is selected while the tape is being moved at a speed which is insufficient for the reliable reading of its longitudinal time codes, the tape is accelerated to a speed sufficient for the longitudinal time codes to be reliably read and a subsequently encountered longitudinal time code is read, the reproduced control pulses are counted between the time that an information signal is selected and the time that the subsequently encountered longitudinal time code is read, and a derived address of the selected information signal is determined, in terms of its respective longitudinal time code, as a function of the value of the subsequently encountered longitudinal time code and the count of the reproduced control pulses.
