Abstract
Methods and systems are disclosed for delivery of one or more channels of programming in an IP network. An edge gateway device may retrieve segments of programming, based on information in a manifest file, and output the segments via multicast to one or more edge devices. Advertising content may be inserted, or replaced if already present, before the segments are multicast. Segments encoded at various bit rates may be available for retrieval. Segments may be selected for retrieval based in part on a quality indicator associated with each segment.
