A current fingerprint that is a function of an operation node and an input storage node is generated. The current fingerprint is compared to a previously generated fingerprint associated with an output storage node and a task associated with performing the operation node on the input storage node is generated.

Techniques and a system are provided for protecting content (or media item) streamed over a network from unauthorized access. As an example, the streaming protection system generates statistics when a client requests a media item. The statistic may be generated based on various factors. The media item is divided into different portions, each portion requiring a different key to decrypt the portion so that it may be viewed by a user. Based on the generated statistic, the streaming protection… Mehr zeigen

Techniques are provided for remotely controlling the distribution of digital assets to users in less-connected venues. When digital assets are cached within the less-connected venues, users within those less-connected venues are better able to consume the assets, and are therefore more likely to purchase rights to consume the assets. Users within a less-connected venue may purchase and consume assets while the target network is completely disconnected from the source network from which the… Mehr zeigen

When digital assets are cached within the less-connected venues, users within those less-connected venues are better able to consume the assets, and are therefore more likely to purchase rights to consume the assets. Users within a less-connected venue may purchase and consume assets while the target network is completely disconnected from the source network from which the digital asset distribution is controlled. Sessions that are initiated within less-connected venues may be transferred outside those venues, to allow users that have purchased assets to continue to consume those assets after they leave the less connected venues.

A system is provided that facilitates achieving a goal associated with a particular video asset. The system may provide an interface through which a user may specify control parameters that are to be the targets of testing, and a goal or combination of goals. The system may control a controller that performs experiments in an attempt to identify optimal values, relative to the specified goals, for the control parameters. The optimal values may be determined and tested on a per-individual-video… Mehr zeigen

A system is provided that facilitates achieving a goal associated with a particular video asset. The system may provide an interface through which a user may specify control parameters that are to be the targets of testing, and a goal or combination of goals. The system may control a controller that performs experiments in an attempt to identify optimal values, relative to the specified goals, for the control parameters. The optimal values may be determined and tested on a per-individual-video asset basis. Further, the controller may generate multiple sets of optimal values for a given video, where each set is associated with a different combination of request attributes. To estimate the optimal parameter values for one video, the controller may use usage information collected for that video, as well as usage information collected for similar videos. Weniger anzeigen

A system identifies user-defined organizational relationships between documents in a collection of documents. The system ranks the documents based on the identified relationships. In response to a user search query, a listing of matching documents is identified. The listing of matching document is presented to the user based on document ranks.
