Each delay block can provide from 1 to 32767 audio samples of delay, where
the audio sample rate is 48KHz. This gives over 16 video frames of delay per
audio delay block, although the actual delay in frames depends upon the
frame rate for the current video standard as follows:

50Hz standards

17.06 frames audio delay

59.94Hz standards

20.45 frames audio delay

Audio delay banks and video frame delays may be used in conjunction to
ensure the audio and video are kept in sync when processing Dolby E/Digital
Encode or Decode, or performing stereo to 5.1 Up-Mix.
