6.9.2. Understanding Dolby-E Frame Rates & Packet Phasing
Dolby-E packets are aligned with video frames. Dolby-E has similar options for frame rates as video.
This module currently supports frame rates of 23.98, 24, 25, 29.97, and 30 fps. For interlaced video
standards such as 525i/59.94 and 1080i/59.94, a Dolby-E frame will span 1 frame, or two fields. For
progressive standards such as 720p/59.94, a Dolby-E frame will span 2 frames.
