1ms A/V. Video: less than 250 pixels
Audio: 10 video lines or less depending
on video format.
The faster the line rate, the longer the audio
delay becomes due to a shorter blanking
period where we transfer the audio packets.

Example calculations:
24p to 60p= 58.3mS
24p to 60i: = 58.3mS
60p to 24p: = 58.3mS
60p to 60p: = 33.3mS
