Abstract
An adaptive bit rate system uses adaptive streaming to deliver content to client devices capable of adaptive bit rate streaming. Enhancing or generating compound manifest files for delivery to clients in an adaptive streaming environment permits a direct acquisition of media segments to services not currently being viewed. For example, the compound playlist can be designed to offer direct access to neighboring channels or other services in the same genre. These novel enhancements to the manifest files may reduce channel change times as well as the efficient delivery of manifest files.
