Abstract
An encoding-locked method for audio processing for audio receiving device includes the following steps: inserting a first encryption key into a first digital signal stream so as to obtain a second digital signal stream, checking whether there is the first encryption key in a received digital signal stream so as to determine whether the received digital signal stream is the second digital signal stream, and when the received digital signal stream is not the second digital signal stream, no processing the received digital signal stream.
