Product data sheet
14.5 Indifferent detection of copy protected signals
Detection of copy protected signals according to the Macrovision scheme (pseudo sync
and AGC pulses) and thus the contents of the status information COPRO (I
bit, D1 of subaddress 1Fh) should be independent of the signal source.

Issue: The detection of copy protected signals is not always stable with deteriorated
VCR signal sources or with certain VCRs or camcorders, especially with spurious
pulses that will be interpreted as pseudo syncs.
Impact: The internal detection circuitry might react too sensitive in a sense that a copy
protected signal is being detected that actually is not copy protected.
Work-around: Sometimes it will be advantageous to average the COPRO status
information (under control of the system microcontroller) for about one minute.
