3.3. SDI Clocked Audio Input IP Core

The Clocked Audio Input IP core converts clocked audio in AES formats to Avalon-ST audio.

For a typical AES input, for each channel, the clocked audio input function does the following operations:

  • Creates a 192-bit validity word, user word and channel status word
  • Presents the words as a control packet after the audio data packet
