TV synchronisation will migrate to network-based IEEE-1588 Precision Time Protocol (PTP) and the SMPTE ST 2059 Standard for a network-delivered reference needed for live IP. This presentation from Paul Briscoe (Consultant, Television Consultancy) provides an overview of these standards and how they are applied to media systems, including the virtual generation of legacy signals, how SMPTE ST 2110 systems use PTP natively and how hybrid systems can be designed.
