TV broadcasters and programmers must embrace a new set of video-delivery techniques to reach consumers in this age of mobile and social entertainment. One of these is over-the-top (OTT) video delivery: digital video programming via the open internet rather than over the air or through a facilities-based service provider that can be sent to any connected consumer electronics device, regardless of location. Online delivery to so many types of consumer devices means that video programmers must produce multiple internet-streaming formats that use different types of security and different ways of inserting ads. This report explains the technical details of the various format and delivery types. Other considerations include the need for maintaining high video quality despite external factors and choosing from among multiple architectural approaches to optimize delivery.
