- The AES/EBU input signals can be delayed
   up to 80mS (2 video frames)for    compensation with delays in an external    video path.
- The AEB-421 can handle DSC signals with    embedded audio of older equipment that    writes data on lines re- served for EDH.
   20-bit A/D conversion.
- Full error detection and handling(EDH)with    the appropriate flag settings and indication.
- Intelligent embedding : when "overwrite"is    off, no em- bedding if audio data is present    in DSC signal.
- Analog and digital audio input.
