An improved system for accessing data within a distributed data storage network (“DDSN”) is disclosed. In a system implementing the disclosed invention, traffic is routed to individual slice servers within the DDSN in accordance with objective criteria as well as user-defined policies. In accordance with one aspect of the disclosed invention, when a data segment is written to a DDSN, the segment is divided into multiple data slices, which are simultaneously transmitted to different slice servers. In accordance with another aspect of the disclosed invention, when a data segment is read from a DDSN, a list of slice servers, each containing a data slice that could be used to reconstruct the requested data segment, is assembled, and sorted in accordance with a preference rating assigned to each of the slice servers. Sufficient data slices to reconstruct the data segment are then read in accordance with the preference ranking of the slice servers.

The method, system and computer program product generate online interactive maps linking tracked objects (in a live or pre-recorded video sequence) to multimedia content in real time. Specifically, an object tracking and link generation (OTLG) utility allows a user to access multimedia content by clicking on moving (or still) objects within the frames of a video (or image) sequence. The OTLG utility identifies and stores a clear image(s) of an object or of multiple objects to be tracked and initiates a mechanism to track the identified objects over a sequence of video or image frames. The OTLG utility utilizes the results of the tracking mechanism to generate, for each video frame, an interactive map frame with interactive links placed in the map frame at a location corresponding to the object's tracked location in each video frame.

Search constraint specific searching for content from a mobile device is disclosed. Following a mobile device generated request for content, a content server provides for the search of content on a network service or personal computer. The search for content may occur directly through the content server or via a connector application. An index engine parses and lists structured and unstructured content, which may be responsive to the search request. The content server or a proxy then provides a sub-set of the search results, that subset corresponding to both the mobile device generated request for content and a search constraint such as mobile device capabilities or network service provider limitations.

A system for automatically pausing a video program in response to detection of the occurrence of a communications event or triggering event.

A method for distributing code resident on a remote application server to a local server. When a client requests information, a request handler on the local server handles the request. If the information is available on the local server, the request handler satisfies the request using this information. If the information is not available locally, the request handler accesses the remote application server to obtain the requested information. The request handler forwards the information to the client and caches it on the local server. Where the information cannot be transferred to the local application server, the request handler establishes a proxy to the remote application server that forwards a client request to the remote application server and a response from the remote application server to the client. The client communicates transparently with the remote application server via the proxy on the local application server.

The present invention is directed to a client-server network system implementing a multi-tier caching strategy for a user to access a document efficiently. The system comprises a client cache assistant serving as proxy for web browsers, a remote cache server managing user-requested documents and a search engine repository storing a huge number of documents as a backup for the remote cache server. Upon receipt of a document request, the client cache assistant examines its client cache to identify the requested document. If not successful, the remote cache server then identifies a copy of the requested document in its own cache and transmits a content difference between the two copies to the client cache assistant. If the server copy is still not fresh or not found, the remote cache server seeks another copy of the requested document from the search engine repository and transmits another content difference to the client cache assistant. The client cache assistant merges the content differences and the original copy into a new copy of the requested document.
