A method and system for encoding data to allow coded data to be passed through legacy equipment having a predetermined format different from the format of the encoded data. Included with the compressed data signal are a small number of bits providing a degraded representation of the signal, so that if it is attempted to play or read the compressed output signal in the legacy format, a degraded representation of the signal is provided. Such a degraded representation is useful for confidence monitoring and identification purposes. |
