ABSTRACT:
A video cassette recorder envelope detection apparatus which can accurately detect an envelope reflecting the state of a system. The envelope detection apparatus may include a reference voltage setter for setting a second reference value which is altered according to comparison of a level of the video signal with that of a preset first reference value, and a voltage comparator for comparing the level of the video signal with that of the second reference value altered in the reference voltage setter. The envelope detection apparatus may also include a reference voltage setter for receiving a bit error rate calculated from an error correction result of the video signal and setting a reference value based on the received bit error rate (BER), and a voltage comparator for comparing the level of the video signal with that of the reference value set in the reference voltage setter.
