Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 7:
8. A method, comprising:
generating, by an integrated circuit coupled to an electronic circuit, a first signal in response to detecting a first synchronization signal internal to the electronic circuit and available outside the electronic circuit,
generating, by the integrated circuit, outside the electronic circuit, a second signal emulating a horizontal synchronization signal internal to the electronic circuit and not available outside the electronic circuit, and
generating, by the integrated circuit, outside the electronic circuit, a third signal emulating a vertical synchronization signal internal to the electronic circuit and not available outside the electronic circuit;
generating, by a trigger circuit of the integrated circuit, trigger signals for externally controlling the electronic circuit, the trigger circuit comprising a counter configured to count edges of the second signal or the third signal; and
generating, by the integrated circuit, second trigger signals based on current values of the counter.
