Unique subscriber states for adaptive stream management

摘要

Consistent with embodiments of the present invention, a system may be provided to provide per-subscriber stream management comprising: a client capable of receiving a playlist containing a subset of segments associated with a video asset; a video application server to request subscriber state information and to build state representations in a subscriber database on a per-subscriber basis; a media segmenter capable of providing the video asset in multiple bit rates; a subscriber state manager capable of managing the current state of one or more subscribers in a subscriber database; and a stream manager capable of requesting the assignment of bandwidth from a wireless infrastructure on a per-subscriber basis.

1. A method comprising:
establishing a unique state associated with a subscriber requesting a first asset, wherein the state is different than the state for a second subscriber requesting the same asset, wherein each unique state comprises a different reference point into the same asset; receiving an updated state specific to the subscriber, the updated state comprising at least information sufficient to dynamically update a playlist based on a finite set of segments deemed reasonable to collect, buffer, and render by the subscriber; and providing the subscriber with the dynamically updated playlist containing a subset of the entirety of the sequence of stream segments based on the received state.
