Abstract: Systems and methods for editing and selectively encoding video. In general, in one implementation, the method includes generating video segments from portions of one or more video sources, at least one video source being encoded to have interframe dependencies; generating a video sequence from the video segments; scanning the generated video sequence to identify invalid interframe dependencies; and selectively reencoding portions of the generated video sequence to generate an output video sequence having valid interframe dependencies. The method may further comprise generating the output video sequence without reencoding valid portions of the video sequence. Valid portions of the video sequence may comprise portions lacking invalid interframe dependencies or buffer violations.

Abstract: Techniques are described for increasing data access performance for a memory device. In various embodiments, a scheduler/controller is configured to manage data as it read to or written from a memory. Read access is increased by partitioning a memory into a group of sub-blocks, associating a parity block with the sub-blocks, and accessing the sub-blocks to read data as needed. Write speeds may be improved by adding a pending write buffer to a group of memory sub-blocks. Such a buffer may be sized to be equal to the group of memory sub-blocks. The pending write buffer is used to handle collisions for write accesses to the same block, allowing two simultaneous writes to any regular memory block to occur.

Abstract: Technology is disclosed for automatically configuring attribute sets, such as object classes and classes of database tables. A system employing an object class, such as an Identity or Access System, configures the object class for use by the system. One version of the system employs a template that includes entries for attributes in the object class. An example entry identifies an attribute and a corresponding meta-attribute. Alternatively, the template may support multiple object classes and include entries with different types of information. During configuration, the system selects an attribute in the object class and identifies a corresponding template entry. The system configures the attribute, based on the information in the template entry. One type of configuration includes the system assigning a meta-attribute from the template entry to the attribute. The system repeats this procedure for each attribute in the object class or at least a subset of the attributes that need configuration.

Abstract: Identity Servers issue and respond to requests for performing remote operations. A local Identity Server receives a request to perform a remote operation. The local Identity Server identifies and executes any required local operations. After completing the local operations, the local Identity Server forwards the remote request to a remote Identity Server, which executes the remote operation. An Identity Server includes a management service, management registry, and request handler. The management service identifies and issues remote request to other servers. The request handler receives remote requests from other servers. The management registry maintains an index of function modules for performing local operations.

Abstract: A method for data transmission to a receiving host, the transmitted data being coded for forward error correction, includes providing a pre-defined set Xk of symbols, having k symbols, at the transmitting host. An individual subset Xnh of the pre-defined set Xk, comprising nh symbols, is provided at each receiving host. An encoded symbol is calculated by the transmitting host based on a pre-defined rateless code. The calculated encoded symbol and the information with which symbols of set Xk is associated is transmitted to each of the receiving hosts. The encoded symbol is decoded by each receiving host using a decoding algorithm based on a pre-defined rateless code. Repeating the steps until each receiving host has retrieved from the received encoded symbols the respective difference set of symbols.

Abstract: Technology is disclosed for limiting the number of central data store accesses required when performing a series of steps, such as a workflow. A local data store is coupled between a central data store and a system carrying out a workflow. Alternatively, a Transfer Engine is coupled between the local data store and the central data store to transfer data between the local data store and central data store. The Transfer Engine allows the data formats in the central data store and local data store to be independent of each other. During a workflow step, the system stores attributes related to the workflow in the local data store—updating modified attribute values and creating entries for newly added attributes. The system determines whether any attributes in the central data store need to be updated with attribute information from the local data store. The system only updates the central data store with local data store attribute values for new and modified attributes when necessary—avoiding central data store updates after every workflow step.
