JUST-IN-TIME DEREFERENCING OF REMOTE ELEMENTS IN DYNAMIC ADAPTIVE STREAMING OVER HYPERTEXT TRANSFER PROTOCOL

摘要

A method of dereferencing by a client in a network implementing Dynamic Adaptive Streaming over Hypertext Transfer Protocol (HTTP) (DASH), the method comprising receiving a first period of streaming content containing a message instructing the client to retrieve an updated media presentation description (MPD) and containing an indicator indicating a location from which the client is to retrieve the updated MPD, retrieving the updated MPD, and dereferencing a link in the updated MPD, wherein the link indicates a location of content to be streamed in a second period of streaming content described in the updated MPD, and wherein the client performs the dereferencing at a time before an end of the first period of streaming content that is twice a length of a minimum buffer time.
