    Abstract: Techniques are disclosed for improving user experience of multimedia streaming over computer networks. For example, a method for presenting multimedia content may generally include receiving a request to stream a media title. In response to the request, unencrypted content for the media title is streamed to a client. While streaming the unencrypted content, a digital rights management (DRM) license to access encrypted content for the media title is requested. After receiving the DRM license, the client switches from streaming the unencrypted content for the media title to streaming encrypted content for the media title. The switching from streaming the unencrypted content to streaming the encrypted content does not interrupt playback of the media title.

    Abstract: Embodiments of the present invention set forth techniques for a content player to stream a media file using multiple network connections. To stream the media file, the content player downloads metadata associated with a requested media file, establishes a network connection with multiple content servers (or multiple network connections with a single content server or both) and begins requesting portions of the media file. In response, the requested portions are transmitted to the content player. The content player may employ a predictive multi-connection scheduling approach to determine which network connection to use in downloading a given chunk.

    Abstract: 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.
