ABSTRACT:
A channel code input and reproduction method and a channel code reproduction apparatus for inputting a channel code having a length of time which is proportional to a magnitude of a channel number. The channel code is reproduced by counting a rectangular wave signal which is generated to detect the length of the channel code. This provides a channel code input and reproduction apparatus of a frame switcher for accurately reproducing a channel code irrespective of a skew.
