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.
Claims13
An audio receiving device, comprising:
- a sensor, configure to convert a piece of audio wave into a piece of analog electric signal;
- a converter electrically connected to the sensor, configured to convert the piece of analog electric signal into a first digital signal stream;
- and
- an encoder electrically connected to the converter, configured to selectively encode the first digital signal stream based on a first encryption key so as to generate a second digital signal stream.
An encoding-locked method for audio processing, comprising:
- inserting a first encryption key into a first digital signal stream by a sending end 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, the receiving end does not process the received digital signal stream.
