The system and method may be utilized to omit recording of unwanted information, such as commercials in a television broadcast, or to automatically locate desired information on any of a number of available information channels without a priori knowledge of the occurrence time or channel of the information.

Abstract: Presented herein is a video enhancer plug-in for a web browser that may either interface directly with the browser or indirectly as a plug-in for another more general multimedia browser plug-in. The video enhancer consists primarily of video enhanced scripts and a library of specialized routines. A script is intended to provide a visually interesting display within a web browser environment and calls upon routines in the library to do so. These routines, for example, may take live video input from a video camera and perform specific functions such as locating the head of an individual within the camera's field of view. Because the script runs within a web browser, it allows components of the system to be widely separated from one another, so long as they are connected across a wide area network such as the Internet.

Abstract: The electronic audio connection system of the present invention provides an experience much like sharing a room with several involved parties, even though the parties are physically separated. Speech enhancement and speech emphasis processing functions ensure parties perceive the speech captured in the audio signals, typically the most important portion of the captured audio signals. To capture audio signals, each space is provided a plurality of microphones arranged in that space so that the sum audio signal captured by the microphones enables the creation of a sharable audio space. Each separate physical space transmits its captured audio signals to a central server via a bi-directional data communications medium. The central server processes the summed audio signals and in turn transmits playable audio signals to each separate physical space. Speakers located in each separate physical space aurally transmit the playable audio signals.

Abstract: The invention enables the apparent display rate of an audiovisual display to be varied. The invention can modify an original set of audio data in accordance with a target display rate, then modify a related original set of video data to conform to the modifications made to the audio data set, such that the modified audio and video data sets are synchronized. When the modified audio and video data sets so produced are used to generate an audiovisual display, the audiovisual display has an apparent display rate that approximates the target display rate. The target display rate can be faster or slower than a normal display rate at which an audiovisual display system generates an audiovisual display from the original sets of audio and video data. The target display rate can be established solely by a user instruction, by analysis of the audiovisual data, or by modification of a user-specified nominal target display rate based upon analysis of the audiovisual data.

Abstract: The invention can enable the position (i.e., location and/or orientation) of one or more untethered objects to be tracked. One or more transmitters, each of which has a fixed and known positional relationship to a corresponding object, each emit a sequence of position tracking signals. Each transmitter can emit a unique, identifiable position tracking signal so that the transmitter (and the object to which the transmitter is coupled) from which a signal was emitted can be identified, thereby enabling the position of multiple objects to be tracked. Multiple receivers receive the position tracking signals emitted by each transmitter. The receivers record the times at which signals are received. These recorded times can be communicated to a controller, which can determine from the recorded times the location of each object at a time that a position tracking signal was emitted from the corresponding transmitter.
