Adjust the Presentation Time from AVTPDUs to align with the reference clock provided by the CRF stream. For detailed information see chapter 10 in https://standards.ieee.org/standard/1722-2016.html. A helpful aid for visualizing CRF and it's advantages can be found at http://grouper.ieee.org/groups/1722/contributions/2014/1722a-rsilfvast-Diagrams%20for%20Common%20Timing%20Grid%20and%20Presentation%20Time%20(for%20review%20and%20discussion).pdf (Look at page 1).
