3.5. AES Format
The SDI cores use the AES standard. The Audio Engineering Society (AES), together with the European Broadcasting Union (EBU), created a digital audio transmission standard known as the AES/EBU standard. The AES standard is a digital audio standard for transporting digital audio signals serially between devices.
Using the AES format requires the entire 64-bit AES frame to be sent serially. As the AES defines the preambles as biphase mark codes, which cannot be directly decoded to 4 bits, you must replace the preambles with X = 0000b, Y = 0001b, and Z = 0010b. This internal AES format serializes the bit-parallel data words by sending the least significant bits (LSB) first, with the audio sample (up to 24 bits).
