Abstract

PURPOSE:To make it possible to easily view a display picture, by displaying a receiving state, or inhibiting the display in case the receiving state is deteriorated and becomes hard to view, in the unit which receives and processes a binary information signal. CONSTITUTION:The receiving error detection circuit 15 consisting of 2 sets of counters counts, for instance, the vertical pulses output by the synchronizing separator circuit 2 by 50 field portion. The superposed sections of a CEEFAX (tele-text) during that time are 2 sections each per 1 field, and 100 sections in all. The number of times of outputs of the FC (framing code signal) detection circuit 11, which have appeared during that time is counted by other counter, and for instance, when the FC detection outputs have reached 90 times or less, that is to say, the receiving error has become 10% or more, an output of the gate circuit 5 is changed to an output of the video detection circuit 1 from an output of ROM4, and it is controlled so that an alarm lamp is turned ON, at the same time.
