System and method for generalized HTTP headers in dynamic adaptive streaming over HTTP (DASH)

摘要

A system and method for streaming content is disclosed. A media presentation description (MPD) may be associated with streaming content, for example, in Dynamic Adaptive Streaming Over HTTP (DASH) over HTTP. The MPD may include an element that provides name / value functionality, e.g., a header element or a URL query element. Element may allow a request to result in the insertion of a custom header. The request may be used for subsegment, segment, or search of the MPD, re-reference of the remote element, or may be triggered by an event. The event may be embedded in either the MPD or the segment.
