    "abstract": "As guest editor, I specifically reached out to Gordon Castle for a contribution to this issue of the journal because it is important to hear from different voices as we work our way through the transition from the serial digital interface (SDI) to Internet Protocol (IP) systems. Rarely, if ever do we get to hear directly from the business/technology people who are making key decisions as we transition to IP. He has recent, direct relevant experience as one of the key decision-makers for a major refresh at a large live sports facility in Europe. He is a senior technical strategist with years of experience working both on the user side at Cable News Network (CNN) and later Eurosport and also on the vendor side at Ericsson. The views and opinions in this article are based on his years of experience, and the points he raises are ones that we, as media engineers and experts, should ponder, both with our employers and in society. Castle asks a number of questions in this article. He answers some of them but leaves others as open challenges. Perhaps, someone would like to tackle one or more of these in an upcoming issue of the journal?—Brad Gilmer, Guest Editor",

        "bio": "Gordon Castle, a vastly experienced technology professional, connects market dynamics to strategic plans and then drives execution that improves business performance and growth. This work has taken him to four countries and positioned him at the forefront of industry change and enabled him to succeed in roles ranging from start-ups to large-scale corporate strategy. Most recently, as senior vice president, technology and operations, Europe Middle East and Africa (EMEA) for Discovery, Paris, France and London, U.K., he was responsible for developing, defining, and implementing the long-term technology strategy of Eurosport, Discovery’s leading sports brand. Before joining Discovery, he held senior positions with a telecommunications company, Ericsson, Stockholm, Sweden. As vice president, head of strategy development, media, Internet of Things (IoT), and applications, he developed strategic plans that enabled new growth areas. Then, as the vice president, the head of strategy development, portfolio, and capital and resource allocation, he oversaw the strategy and allocation of resources for the Ericsson portfolio. He has more than 30 years of experience working in the media industry, which has included roles such as director of entertainment, media, and communications with Pricewaterhouse, Coopers, Atlanta, GA; Senior Vice President (SVP) and the head of cable news network (CNN) Technology, Atlanta, responsible for the News Group’s technology strategy, implementation, and training; as well as serving as an SVP—senior technology fellow with Turner Broadcasting, Atlanta. Throughout his career, he has helped his organizations embrace innovation by conceiving, planning, and executing large-scale initiatives that have changed organizations and the way people work.
