Abstract

The invention relates to a circuit for recognising whole-picture frames of C, D and D2-MAC packet signals for generating whole-picture frame-synchronous pulses, particularly clamping pulses for clamping amplifiers in satellite receiving systems. To make such a circuit cost-effective, and at the same time ensure an operation without problems, it is proposed according to the invention to evaluate not, as is known, the line synchronisation words and the frame-synchronisation word but the white and black signal of reference line 624 and the frame-synchronisation sequence transmitted in line 625. For this purpose, the baseband signal is supplied to a reference line detection circuit (RZE) for detecting the white and the black reference signal (SW, SS) which, when the reference line is detected, emits an enable signal, and on the other hand, directly to a frame synchronisation sequence detection circuit (RSE) in which it is logically combined with the enable signal by means of an AND gate (UG2), the output of which is connected to the input of a counter (Z) which supplies whole-picture frame-synchronous pulses at the output (A). <IMAGE>
