SMPTE ST2110 and PTP in Virtual Production (vETC at Siggraph 2023 - Day 1, Aug 8th)

The integration of ST2110 and PTP into the Unreal Engine is enhancing
the deployment of virtual production stages. The use of ST2110 to
communicate the inner view frustrum between render nodes reduces
the camera to display latency while the use of ST110 video essense
streams for capture and display removes the complexities of traditional
SDI/HDMI or Display Port.

----------
vETC is a virtual conference of significant presentations around emerging technologies (e.g., OSVP and ICVFX) and their impact on the M&E industry. Programmed by the Entertainment Technology Center@the USC School of Cinematic Arts and recorded live, speakers present concepts, workflows, business models, and case studies in showcasing disruptive and enabling technologies.
The concept of the vETC series came about in 2015 to fulfill the desire to populate an independent conference for the emerging tech topics while implementing the virtual capabilities by expanding beyond traditional physical conference attendees. It has advanced to cover a wide breadth of mainstream topics providing great insight into early-stage technologies in a TED-talk-style platform. Unlike unrecorded conferences, there is no single audience for this video series - anyone who wishes to catch up can hear from experts right at their personal computers.

This was a great talk by Thomas. Thank you for making it available.

No it was not. No idea why he drives that GPS connection to UTC. It seems totally unnecessary for video processing. It only has to be synchronized between each other to work perfectly synchronized to each other, not to Global Time Sources.

The PTP is only protocol which ensures that clocks of all connected devices are synchronized to one called Grand Master Clock. It could be done using PPS and coaxial cables. It is just convenient as it adjusts automatically for cable length. It is not necessary or revolutionary.

Why that has to be synchronized to GPS? Is it not enough to keep good quality oscillator?
