The introduction of digital television to the U.S. market proceeded in a number of steps: standardization in the early 1990’s, first introduction of transmission and sets in the late 1990’s, and accelerated adoption over time, culminating as NTSC television was shut off in 2009. The audio standards (that were thought to be easy to do so came first on the testing schedule but turned out to be far more complex than expected) added a number of features to conventional workflows that are only now becoming to be understood in some areas of the vast television production chain. This workshop will discuss what the situation is today from several points of view, and how the standards are likely to be promulgated over the next few years.
