Abstract:
Se proporcionan técnicas para modificar dinámicamente interconexiones entre componentes en una aplicación. Las técnicas incluyen recibir un perfil de un productor de datos por cada puerto de salida dentro de una aplicación de programas y sistemas de programación o software a ser ejecutada en uno o más procesadores, recibir un perfil de suscripción de datos por cada puerto de entrada de cada componente de la aplicación, establecer conexiones entre los puertos de salida y los puertos de entrada de los componentes en la aplicación sobre la base de una comparación de cada uno del perfil del productor de datos y cada perfil de la suscripción de datos, ejecutar la aplicación en uno o más procesadores para procesar flujos de datos, recibir cualquiera o ambos de un nuevo perfil del productor de datos o un nuevo perfil de suscripción de datos durante la ejecución de la aplicación, y establecer al menos una nueva conexión entre un puerto de salida y un puerto de entrada sobre la base de una comparación revisada de los perfiles de datos recibidos que incluya su nuevo perfil de datos.

Techniques for dynamically modifying inter-connections between components in an application are provided. The techniques include receiving a data producer profile for each output port within a software application to be executed on one or more processors, receiving a data subscription profile for each input port of each component of the application, establishing connections between the output ports and the input ports of the components in the application based on a comparison of each data producer profile and each data subscription profile, executing the application on one or more processors to process streams of data, receiving either or both of a new data producer profile or a new data subscription profile during the execution of the application, and establishing at least one new connection between an output port and an input port based upon a revised comparison of the received data profiles that include the new data profile.

Abstract:
Techniques for securely and adaptively delivering multimedia content are disclosed in which a set of alternate access units for each time slot is obtained. Then, the encryption stream index of each access unit from the set of alternate access units of the previous time slot are obtained. An encryption stream index is then assigned to each access unit in the set of alternate access units in the current time slot, such that the encryption index increases over time. Thus, the invention overcomes the problem of encrypting a multimedia stream that may have multiple access units for each time slot by selecting the encryption index for each access unit such that the encryption index increases, regardless of which access unit the delivery system (e.g., server) selects for transmission.
Abstract:
A system and method for streaming data over a communications network with varying streaming conditions, includes conditioning a data stream to create conditioned data representations including encoded representations targeting running conditions, wherein conditioning includes partitioning the data stream into data units, and generating the encoded representations of each of the data units, packaging the conditioned data representations with metadata specifying a target set of running conditions, wherein the conditioned data representations are packaged by pre-computing one or more trajectories among the encoded representations based on a given finite set of streaming conditions, observing a current run-time condition and selecting one of the packaged conditioned data representations for streaming over the computing network according to the running conditions in view of the current run-time condition in accordance with the observed current streaming condition, and a communications network responsive to the media server for streaming the selected packaged conditioned data representation.
