Abstract
Official abstract text for this publication.
One embodiment of the present invention sets forth a technique for adapting playback bit rate to available delivery bandwidth in a content delivery system comprising a content server and a content player. A content player periodically estimates whether a given playback bit rate can feasibly provide complete playback for a given title assuming currently available bandwidth. If playback becomes unfeasible at a current bit rate assuming currently available bandwidth, then the content player adapts the bit rate downward until a feasible bit rate is achieved. If playback is feasible using a higher bit rate, then the content player may adapt the bit rate upward.
First claim
Opening claim text (preview).
We claim: 1. A method for adaptively downloading a digital content title from a content server to a content player, the method comprising: downloading, to a content buffer within the content player, at least one unit of the digital content title from a first encoded sequence included in a plurality of encoded sequences stored on the content server, wherein each encoded sequence comprises the digital content title encoded at a different bit rate and is capable of being separately p…
