Disclosed are various embodiments for a client application for streaming media. The client application estimates the bandwidth of the client and the latency between the client and a media distribution service. A bit rate for a media stream is determined using the latency, a buffer state, and the estimated bandwidth. A time to send the request is determined using the estimated bandwidth and latency.

Generating requests for streaming media

Disclosed are various embodiments for a service for selecting the bandwidth of a media stream. The service correlates the buffer state of a client with previously communicated portions of the stream. The service then determines a bit rate for subsequent portions of the stream. A manifest may be generated indicating a source for content at the determined bit rate.

Bit rate selection for streaming media

Disclosed are various embodiments for selecting fragments of a media item. An estimated bandwidth for a client is calculated. A confidence score for the estimated bandwidth is determined. When the confidence score falls below a threshold, the estimated bandwidth is modified. A fragment for the media item is selected using the modified estimated bandwidth.

Live stream manifests for on demand content

Techniques are described for facilitating the delivery of digital content using gossip protocols. A group of client devices share information about network conditions in sideband communications using a gossip protocol. Each of the client devices then uses this information to make decisions about how to access content. By providing accurate and current information about network conditions the occurrence of buffering events and/or fatal errors may be significantly reduced or eliminated.

Content delivery using gossip protocols

A technology is described for providing plotline information associated with media content. An example method may include receiving a request from a customer via an interface for plotline information stored on a data store. The plotline information may be included in media content where the plotline information may include a plurality of plotlines featured in the narrative of the media content. The plotline information may then be identified in the data store, and a graphical visualization of the plotline information included in the media content may be generated, where the graphical visualization may display the plotline information as corresponding to the narrative of the media content.

Visualization of plotlines

Disclosed are various embodiments for requesting fragments of a media item. A latency to a media distribution service and bandwidth for a client are estimated. A time to request a subsequent fragment from the media item is determined. Sources for the fragment are scored and one of the sources is selected. The fragment is requested from the selected source.

A technology for content delivery is provided. In one example, performance of a caching network, performance of a delivery network, and customer demand are modeled. Instructions are provided for a client device on how to request content based on the modeled performance of the caching network, the modeled performance of the delivery network or the modeled customer demand.

Content delivery

Techniques for delivering content are described that vary the bit rate with which the content is delivered to achieve a consistent level of quality from the user's perspective. This is achieved through the use of quality metrics associated with content fragments that guide decision making in selecting from among the different size fragments that are available for a given segment of the content. Fragment selection attempts to optimize quality within one or more constraints.

Delivering media content to achieve a consistent user experience

Disclosed are various embodiments for a manifest generation service. A manifest generation service determines a bit rate for an on demand content stream to a client. A manifest is generated indicating a source for content at the determined bit rate. The bit rate is determined and manifests are generated repeatedly to adapt to changes in network conditions during the stream.

A technology for content delivery is provided. In one example, performance of a caching network, performance of a delivery network, and customer demand are modeled. Instructions are provided for a client device on how to request content based on the modeled performance of the caching network, the modeled performance of the delivery network and the modeled customer demand.

A digital license is migrated from a source platform to a target platform. At the source platform, a migration image is produced to include the license and corresponding data therein, and the license is deleted from such source platform. At the target platform, permission is requested from a centralized migration service to migrate the license in the migration image to the target platform. The migration service determines whether to permit migration of the license based on predetermined migration policy. Upon receiving the requested permission as a response from the migration service, the migration image is applied to the target platform by un-tying the license from the source platform and re-tying the license to the target platform.

Digital license migration from first platform to second platform

An Application programming interface (API) provides functions for generating applications, documents, media presentations and other content. These functions allow developers to obtain services from an operating system, object model service, or other system or service.
