Audio Embed or Audio Embed with Avalon
The SDI Audio Embed MegaCore function consists of an encrypted audio embedder
core and a register interface block that provides support for an Avalon-MM control
bus.
The audio embedder accepts the audio in AES format, and stores each channel pair in
an input FIFO buffer. As the embedder places the audio sample in the FIFO buffer, it
also records and stores the video clock phase information.
When accepting the audio in AES format, the SDI Audio Embed MegaCore function
either maintains the channel-status details or replaces the details with the default or
the RAM versions.
