Abstract:
Techniques are disclosed for improving user experience of multimedia streaming over computer networks. More specifically, techniques presented herein reduce (or eliminate) latency in playback start time for streaming digital media content resulting from digital rights management (DRM) authorizations. A streaming media client (e.g., a browser, set-top box, mobile telephone or tablet “app”) may request a “fast-expiring” license for titles the streaming media client predicts a user is likely to begin streaming. A fast-expiring license is a DRM license (and associated decryption key) which is valid for only a very limited time after being used for playback. During the validity period of such a license, the client device requests a “normal” or “regular” license to continue accessing the title after the fast-expiring license expires.

Claim (Index 1):
A computer-implemented method, comprising:\n presenting, in a streaming media interface, a set of one or more media titles available for streaming from a library of media titles; prior to receiving, from a user interacting with the streaming media interface, a request to stream a first media title from the library, sending a request for a fast-expiring license for the first media title, wherein the fast-expiring license is valid for a fixed time interval after playback of the first media title begins, wherein the fixed interval is less than a playback time of the first media title, and wherein the first media title is predicted to be a next selected media title for streaming; receiving the requested fast-expiring license; and in response to receiving, from the user interacting with the streaming media interface, the request to stream the first media title:\n retrieving an encrypted first portion of the first media title, \n decrypting the encrypted first portion using a key associated with the fast-expiring license, and \n initiating playback of the first portion of the first media title on the streaming media interface.
