Abstract: Data Network Technology has advanced to the point where packet video infrastructure can realistically be considered for different workflows. SMPTE 2022-6 provides full bandwidth video transport in the OSI Protocol Stack and by doing so, further enables the transition from SDI to packets. Encapsulation provides flexibility, extensibility and interoperability not otherwise available with existing SDI baseband video standards. Some argue that the overhead costs associated with encapsulation can be prohibitive for HD-SDI and UHDTV data rates push the cost curve potentially higher. But, these cost curves fall with Moore's Law, and in the long run, the flexibility of using packet video to enable intelligent workflows provides better monetization of content and extends the life of CAPEX investments. Examining the different approaches to facility signal routing and distribution demonstrates the tradeoffs between different network technologies and their suitability for various work flows. Using Ethernet AVB, which includes PTP, is one approach, and COTS IP networks equipment with NTP is another. Using an IP Gateway as part of system design today provides a compelling solution bridging today's SDI with tomorrow's packets. Comparing and contrasting these methods provides insight into their suitability for a given workflow, the costs, and event timelines for implementation. Understanding these timelines is critical to business planning.
