This edition of the journal focuses on various aspects of the digital video sector. It is well acknowledged that advertising is one of the revenue engines that contributes heavily to cable and online distribution. Dynamic ad campaign management and targeting have also contributed to revenue but also system complexity increases. The first article gives an overview of methods for effective verification of these complex systems – advertisers often insist on verification before payment is given. This paper describes several methods that are usable in different large-scale implementations. As video distribution continues to be a significant use of plant bandwidth, innovative new technologies permit increases in effective bandwidth without massive infrastructure rebuilds . The second paper describes techniques used to increase bandwidth available for data services. Content distribution from program provider to distributor has been one of the least-changed technologies from the early days of cable to the current time. However, recent developments in FCC spectrum reassignment and the ubiquity of IP capacity are moving the least-changed technology to the most-quickly disrupted. The third paper describes novel applications of new methods of content distribution from programmer to consumption points. The fourth paper describes how Blockchain technology can be used in interactive content and other services to ensure privacy, synchronization and, verification of consumer input. Secure and private two- way interaction between end-consumers and the service provider has been a challenge and can benefit from the cryptographic principles of Blockchain. SCTE•ISBE standards, and the operators that adopt them, keep high-quality content and services as top- of-mind goals. In the final paper, the newest high-quality video, High Dynamic Range (HDR) / Wide Color Gamut (WCG) is explored from the qualitative perspective. HDR/ WCG sets consumer expectations of picture quality to a new level. This paper explores the impairments that may impact HDR / WCG video. We thank the individuals who contributed to this issue of the Journal of Digital Video, including the authors, peer reviewers, and the SCTE•ISBE publications and marketing staff. We hope you enjoy this issue and that the selected papers spark innovative ideas and further cement essential knowledge in digital video.
