Bits by the Bay 2024

Produced by James Snyder.

In the U.S. we have been living with the 29.97fps video frame rate since the advent of color in 1953.  This legacy of NTSC analog television is so deeply ingrained in all aspects of broadcast and production that it's often forgotten or taken for granted.  Some equipment and production software may not even provide an option to use integer (30/60) rates for recording or display.

There are many factors behind the continued use of fractional frame rates (as well as interlaced video), but most have become irrelevant over time.  This session will review and continue the discussion of the problems created by these legacy concepts, and how they might finally be eliminated.

S. Merrill Weiss is a consultant in electronic media technology and technology management. His career spans 54 years in electronic media and related fields, with 45 years in management and consulting. Prior to consulting, he served in most engineering capacities in radio and television stations and managed a large systems-engineering activity for a top-three U.S. television network.  Along the way, he made major conceptual and technical contributions to technologies such as the Serial Digital Interface (SDI), RS-422 machine control, High Definition Television (HDTV), and the Archive eXchange Format (AXF).  Weiss helped produce the tests that led to the first digital television standard, on which nearly all subsequent digital video standards are based, and he co-chaired the international task force that developed the foundation and roadmap on which both the exchange of program material as bitstreams and file-based workflows are based

An Emerging Technical Standard to Protect Against AI Fakes: C2PA

Produced by Mike Plamer.

The Coalition for Content Provenance and Authenticity (C2PA) is an open technical standard providing publishers, creators, and consumers the ability to trace the origin of different types of media.  It provides the technical means to declare where media was captured, by whom, by what device, geolocation information from the point of capture, and any production or distribution processes that may have been applied.  C2PA allows producers to lay claim to their video in a way that cannot be faked or modified.  This not only protects their brand against AI fakes, but also allows them to better manage and monetize their own content and archives.

Technically, C2PA defines a schema for describing provenance and specific assertions of fact.  It allows this description to be digitally signed and locked to the media file through the use of certificates and a hierarchy of certificate authorities – very similar to how internet domains are protected today by certificates.

Day-to-Day Operation in the Hybrid World of SDI and SMPTE 2110

Produced by Fred Willard.

This session walks through a typical day in the life of an engineer in managing quality and reliability in a hybrid SDI/2110 facility, which is where most of us will be the next few years. IP is just another I/O interface: It’s a way to get video, audio, and data to or from a switch. These presentations will discuss what operators and engineers need to know.
