Distribution in the UHD Era
Paul Briscoe Once upon a time, there were few broadcast TV standards. Each used its own regional image formats, color encoding scheme and sound and vision modulation standards. High-power over-the-air (OTA) transmitters broadcast the signal on internationally coordinated and regionally allocated radio frequency (RF) channels, making it easy for viewers to tune in programs. It was a robust model that forever shifted the entertainment paradigm. The upstream technologies quietly evolved from analog to digital, and home TV sets reached the performance limits the standards allowed. This was a simple, stable ecosystem, based on a daily programming schedule of shows and monetized by interstitial soap commercials. Life was simple, and people were happy.
