ABSTRACT:
A time and zone metering system wherein a central store is used to accumulate the metering pulse total for each line. The central store consists of a magnetic disc with which a line scanner is synchronized. Each line is equipped with a pulse plus bias line gate that is also wired into a gating arrangement with the timing pulses, so that a combination of the allotted time by the scanner and the presence of a metering pulse is effective to cause a temporary record to be made. Included in the system is a timing means to verify the authenticity of the metering pulses. After storage of the metering marks in the temporary store other logic is effective to place the marks in the stores reserved for a particular line.
