Systems and methods for encoding a DMX data stream and decoding an AES digital audio stream

A method of encoding a Digital Multiplex lighting protocol (DMX) data stream into a balanced Audio Engineering Society/European Broadcasting Union (AES) digital audio stream, the method comprising:

• receiving a DMX data stream having DMX data;
• shifting the DMX data stream to a Transistor-Transistor-Logic (TTL) level;
• formatting the DMX data stream into a plurality of packets;
• inserting the plurality of packets into an AES digital audio stream to produce an encoded data stream carrying the DMX data;
• shifting the encoded data stream to an unbalanced AES digital audio stream;
• and
• transforming the unbalanced AES digital audio stream to a balanced AES digital audio stream.

A Digital Multiplex lighting protocol (DMX) decoder, comprising:

• an Audio Engineering Society/European Broadcasting Union (AES) formatter configured to receive an AES digital audio stream having a cyclic redundancy code value and DMX data;
• a digital signal processor configured to receive the AES digital audio stream, to determine whether the cyclic redundancy code value is valid, and to extract the DMX data from the AES digital audio stream if the cyclic redundancy code value is valid and to retrieve stored DMX data if the cyclic redundancy code value is not valid;
• a universal asynchronous receiver and transmitter configured to receive the DMX data;
• and
• a level shifter configured to shift the DMX data to a DMX output level.
