Abstract: A computer system for overlaying content in a designated area of a web page is disclosed. The computer system may be used to run executable code configured to identify a data field in a received web page, insert a visible user control substantially adjacent to the data field, display the web page comprising the user control, and cause a value in the data field to be tracked upon actuation of the user control.

Abstract: A method and apparatus for data retrieval by a computing system and a plurality of agent computers in a distributed network is disclosed. The computing system sends a request to each agent computer to perform a search at a node. The agents perform the searches. The agents thereupon send the resulting data to the computing system for storage in a central database.

Abstract: A computing system for tracking price changes in assets like products and services includes a data storage device for storing executable code, and a processing system associated with the data storage device. The computing system receives an identity of an asset with a price that is subject to change over time. A rule is identified for determining whether a specified action is authorized in the event the price changes. The computing system tracks the price over time, identifies any changes in the price, and issues a notification regarding a change in the price when the rule authorizes the action.

Abstract: The present invention provides a system and methods for producing multiple encoded representations of a video input sequence. The multiple representations produced each contain identified synchronization frames that allow a server and a client to switch between streamed representations in real time without interruption. Synchronization frames are frames of encoded video that can be independently decoded. A representation can thus be decoded starting at a synchronization frame. Each synchronization frame in one representation has a corresponding synchronization frame at a substantially similar temporal location in any other generated representation of the same video input sequence. The temporal co-location of synchronization frames in all representations facilitates the dynamic switching between representations during the streaming process.

Abstract: A system and method are provided that permit access to a local resource, such as a media content file, without the security warnings typically encountered. The system has a software component or set of components that validate a hyperlink to a local (or remote) resource in the context of the network security environment and securely allows that hyperlink to access local (or remote) resources without being subject to additional restrictions or user inconvenience. A method for generating the hyperlink is also disclosed.
