The Technology of Broadcast Television and Its Impact – Past, Present, and Future
Over the last 80 years, the technology of broadcast television has radically evolved in four major steps, from analog black & white to analog color, digital high-definition TV, and the latest ATSC 3.0 digital system for ultra-HDTV. This talk by Glenn Reitmeier will briefly review the history of television standards in the US and discuss the fundamental aspects of the technology used in each generation of standards. It will also present the highlights of the latest ATSC 3.0 standard that is capable of ultra-high definition, high dynamic range video, immersive audio, new broadcast network topologies, and a new level of interoperability with the internet. It will conclude by briefly discussing the impact and relationship that broadcast television standards have had with other forms of television distribution and some of the future potential for ATSC 3.0.
