Abstract: A method includes receiving, at a first level distribution node of a plurality of first level distribution nodes of a hierarchical media distribution system (HMDS), a request for a content item (associated with segments corresponding to a time order) from a first endpoint device. The method includes, in response to receiving the request, sending, from the first level distribution node, a first data stream corresponding to a first segment of the content item to the first endpoint device and sending first information (indicating the request and a first end time of the first data stream) to a second level distribution node of a plurality of second level distribution nodes of the HMDS. The method includes receiving, from the second level distribution node, a second data stream corresponding to a second segment before the first end time has been reached and sending the second data stream to the first endpoint device.
