Abstract: Copy protected materials are backed up or restored and made available for play on electronic media players through an online retrievable system. Corrupted segments of electronic media storage files are identified and located prior to being read, executed, or played. An uncorrupted copy from the network is then located, and software instructions provide for the storage of the uncorrupted segment of the file on electronic media player, merging the uncorrupted segment into the reading, executing, or playing of the electronic storage media file to seamlessly produce an output in real-time that is indistinguishable from the uncorrupted file.

Abstract: A system and method of storing information about tree structures. The method includes, for each given tree, identifying the nodes and the relationships between the nodes, and for each parameter, if more than one node of any of the given tree shares the parameter, then defining a scoping for the parameter to cover all of the nodes to which the parameter is applicable. The scoping includes applying one or more scope types having a varying specificity. The resulting information stored about the tree structure is substantially reduced in size in comparison to information about tree structures stored in a conventional manner, thereby reducing storage space requirements.

Abstract: Methods to enable optimization of discontinuous rank metrics are described. The search scores associated with a number of search objects are written as score distributions and these are converted into rank distributions for each object in an iterative process. Each object is selected in turn and the score distribution of the selected object is compared to the score distributions of each other object in turn to generate a probability that the selected object is ranked in a particular position. For example, with three documents the rank distribution may give a 20% probability that a document is ranked first, a 60% probability that the document is ranked second and a 20% probability that the document is ranked third. In some embodiments, the rank distributions may then be used in the optimization of discontinuous rank metrics.

The extended multimedia file structure includes: a metadata section including a media initial object descriptor (IOD) field and at least one track pointer; and a media data section including at least one media block indicated by the track pointer, wherein the at least one track pointer indicates a detail media resource contained in an embedded multimedia file or an external multimedia file.

Abstract: A new continuous query to a data stream management system (DSMS) may use a stream or a relation which may or may not be used by continuous queries previously registered in the DSMS. The DSMS is programmed to modify an execution plan to accommodate execution of the new query while continuing to execute the previously registered continuous queries. The modified execution plan may include new operators and/or share existing operators. The DSMS is programmed to cause operators which output a relation to propagate a current state of the relation to each newly-coupled operator that uses the relation. The current state is propagated only to operators that have been newly coupled and have thus not yet received any state information previously. After propagation of current state to newly-coupled operators, results of processing any new data for the relation are supplied to all operators coupled thereto, including newly-coupled operators and existing operators.

Abstract: Techniques for remote redirection are discussed. Redirection may be used to mimic a local user experience on a remote system. Redirection may include redirecting a pointer file, such as a shortcut, to account for remote access to a source file designated in the pointer file. The pointer file may be remapped so that the pointer file's file path accounts for a path from the remote access to the source file. Operating system (OS) information may be forwarded to the accessing system so that the redirected pointer file may be presented in accordance with the remote system's (OS). Redirection may be used to present a directory remotely in accordance with operating system running on the system being accessed.

Abstract: A new continuous query to a data stream management system (DSMS) may use a silent relation whose source does not provide any heartbeats. During execution of any given operator, the DSMS processes data from one input (“active input”) using its time stamp as if the same time stamp is received from another input whose relation has fallen silent (“empty input”), if one or more predetermined conditions are met. One predetermined condition is that the empty input's operator has all its own inputs silent. And another predetermined condition is that a maximum time stamp that is currently present among all the inputs of the empty input's operator is equal to a time stamp that was last received from these same inputs. When both conditions are met, previously received data from the empty input is time stamped with the same time stamp as the most recently received data from the active input.

Abstract: Markup language node level hash join operations for evaluating a query language query are performed. The markup language node level hash join mechanism, i.e. the “XHashJoin” operator, is a multi-way join operator that uses two hash tables, BUILD and PROBE, to intersect document nodes from multiple index scans and to buffer intermediate query results. The BUILD hash table stores document nodes matching the predicates of a query, and buffers document nodes satisfying extraction nodes, of each portion of the query up to a current portion of the query being evaluated. The BUILD hash table and the PROBE hash table are switched at each portion of the query being evaluated. Query results are generated by linking document nodes buffered in the BUILD hash table based on the semantics of each extraction node.

Abstract: Systems and methods for processing an index are described. To insure that the most updated index is available without having to update the index after every change (which can consume enormous resources), a specially marked postings list is generated for a changed item. During retrieval, the specially marked postings list supplements the existing content of an inverted index referencing the changed item. In this manner, the retrieval result for items containing the term under which the changed item was originally indexed is updated in accordance with the specially marked postings list to insure the most accurate retrieval result.

Abstract: Client node caching in a global file service. A client node receives a leaf image from a remote storage node storing a base image that is read-only accessible to the client node. The leaf image has a portion of the base image modified by the client node. The client node stores the leaf image in a cache on the client node. Unmodified portions of the base image are accessed from the remote storage node. Modified portions of the base image are accessed from the cache. The leaf images may comprise a branch modification log having portions of the base image modified by the client node and a metadata structure. The metadata structure has pointers to the modified data in the branch modification log and pointers to data unmodified by the client node in the base image. Alternatively, the leaf images may comprise a change volume for changes made to the base image by the client node.

Abstract: The present invention provides a computer implemented method, data processing system and computer program product for limiting instances of a client-server program within a plurality of platforms in a restricted distributed network. The data processing system receives an invocation of the client-server program. The data processing system assigns a write file to the client-server program wherein the write file has a write file name and the write file is on a distributed file system accessible to the plurality of platforms. The data processing system determines whether the write file is available. Responsive to a determination that the write file is available, the data processing system opens the write file for writing wherein the write file is associated with the client-server program. The data processing system, responsive to a determination that the write file is available, forms an addressing file having addressing information of a first instance of the client-server program.
