The broadcast industry is undergoing significant changes that impact nearly all aspects of business and technical operations. In this Q&A sit-down, Ian Valentine, engineer and business director, Video Products at Tektronix discusses three major trends impacting the broadcasting industry, covering both content production and delivery. As Valentine explains, these trends will require that video engineers and technicians adapt to some significant changes and embrace new tools and workflows.
Broadcast television is the point where the creative arts and technology meet. It’s different from any other discipline as to operate at an optimum level, and get the best possible quality, artisans, producers, and creatives have a deeper technical understanding of their craft than any other artistic discipline. And over the years, the demarcation between creativity and technology has become blurred as members of the creative teams have found themselves delving deep into engineering disciplines.
U.S. broadcasters are required to keep logs and, in some special cases, self-report to the Federal Communications Commission (FCC) to prove compliance with FCC rules related to, among many other things, emergency alerting. Organizations failing to do so face increasingly significant fines. That’s why it’s so important for broadcasters to have a solid emergency alerting and compliance protocol in place — one that includes a regular Emergency Alert System (EAS) and Common Alerting Protocol (CAP) system check-up.

UHD rollout has been average rather than stellar to date. Matthew Goldman, Senior Vice President, Technology, Media Solutions, Ericsson provides an insightful explanation about why this might be and what issues might tip the scale.
Historically, broadcast-related activities had to located near the actual broadcast production chain. But with the advent of cloud services, many auxiliary broadcast services can be located anywhere.
In this series of articles, we will explain broadcasting for IT engineers. Television is an illusion, there are no moving pictures and todays broadcast formats are heavily dependent on decisions engineers made in the 1930’s and 1940’s. In this article we start to look at the human visual system and color temperature.
The number of mobile phone video viewers in the United States is expected to reach almost 170 million this year. An additional 10 million may be added by 2020. With such large and increasing audiences, broadcasters are eager to serve these viewers. As streaming live over LTE networks becomes increasingly common, operators that are prepared by using multicast ABR will be the long-term winners.
The broadcast industry is on the cusp of a new era with the launch of ATSC 3.0 This flexible platform supports multiple types of encoding, which can result in viewers always getting the best available signal over a variety of reception conditions.
