SMPTE 324M – Television – Serial Interface for Multiplexing Eight AES Data Streams
This standard defines a method of mapping up to eight synchronous streams of AES3-compliant data into a self-clocking serial interface. When used for PCM digital audio, the interface can carry up to 16 channels of linearly encoded audio and auxiliary data. Alternatively or concurrently (within the eight stream limit), the interface may be used to carry streams of compressed audio or other data that is packaged into an AES3- compliant stream. The interface is transparent to any data type that is packaged in an AES3-compliant stream that is synchronous with the multiplex.
