What happens if the HDCD Decoder detects valid command code using non-HDCD encoded recordings?

There is an extremely small probability that the decoder will detect a false command code. The combination of the synchronizing pattern with the bit equivalence for all valid commands and checksum addition to the command code packet requires a match that approximates 39 sequential bits. Pacific Microsonics has mathematically calculated that a false detect would occur approximately once every 150 million years for a dual channel audio signal in which both channels must match within a one second interval with identical gains commands for both channels.
