Abstract: A precision motion platform carrying an imaging device under a large-field-coverage lens enables capture of high resolution imagery over the full field in an instantaneous telephoto mode and wide-angle coverage through temporal integration. The device permits automated tracking and scanning without movement of a camera body or lens. Coupled use of two or more devices enables automated range computation without the need for subsequent epipolar rectification. The imager motion enables sample integration for resolution enhancement. The control methods for imager positioning enable decreasing the blur caused by both the motion of the moving imager or the motion of an object's image that the imager is intended to capture.

Abstract: Identification of starting and ending times of commercial breaks and commercials within those commercial breaks found in audiovisual content is disclosed. A solution to a “batch optimization” problem is used in which commercial locations within a set of audiovisual content are detected as a group by choosing a set of commercial locations which optimizes a cost function which can include considerations of, for example, 1) one or more cues, 2) relative locations of commercials within the audiovisual content, and/or 3) probability models based on statistics obtained regarding characteristics of typical commercial and commercial breaks. Optimization can be done over the total set of commercial location decisions, rather than on a per-commercial basis. Additionally, the cost function can be iteratively evaluated and many more types of cues and combinations of cues can be used in detection of commercials.

Abstract: A stream of time-ordered data, such as a movie, is divided into multiple fragments of equal length, which are repetitively transmitted at different respective repetition rates. The fragments are reordered for transmission so that those which occur near the beginning of the original data stream are transmitted more frequently than those which occur later in the data stream. When a user enters a request to utilize the data, the individual fragments are stored upon receipt at the user's premises, and reassembled into a contiguous stream. The ordering of the fragments is such that the wait time required before utilization of the data can begin is limited to a predetermined maximum, and at least one copy of every fragment becomes available by the time it is needed.

Abstract: A method for enabling a user to review a body of information that includes first and second segments from respective first and second information sources includes: storing second segment digital data representing the second segments; receiving an indication that the user has selected for display a particular first segment; identifying one or more of the second segments that are related to the particular first segment by comparing first segment digital data to the second segment digital data; and providing display digital data for display of one or more representations or portions of the identified second segments contemporaneously with display of the particular first segment. The display digital data enables the displayed representations or portions of the second segments to be selected by the user when displayed.

Abstract: A method for displaying interactive advertisements on a television having a controller connected thereto and configured for receiving input from a viewer of the television is disclosed.

The method generally comprises requesting action by the viewer of the television, modifying an advertisement based on the action of the viewer, and displaying the modified advertisement on the television.

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: A system and method for review of news content (audio, video and/or textual news content), such that an overview of the news content can be quickly ascertained and flexibility in the manner in which it is presented are provided. News programs (e.g. television news programs) and news stories (e.g., on-line news) are acquired and the system enables the user to easily move among and randomly access the segments of news programs and quickly locate the segments of a particular subject. News stories related to the segment of news program being viewed can be identified and displayed. Flexible playback allows speeding-up the display of the news program while displaying summary of one or more program segments and accelerating playback of a paused program after resuming from the pause. The system can additionally indicate to the user which news story is currently being viewed, and which news stories have already been viewed.

Abstract: An entropy efficient video coder for wavelet pyramids approaches the entropy-limited coding rate of video wavelet pyramids, is fast in both hardware and software implementations, and has low complexity (no multiplies) for use in ASICs. It uses a modified Z-coder to code the zero/non-zero significance function and Huffman coding for the non-zero coefficients themselves. The encoding unit includes a significance function generator that receives coefficients and outputs a single significance bit. A zero coefficient eliminator receives coefficients in parallel with the significance function generator and outputs coefficients if non-zero. Output from the significance function generator is coded using the modified Z-coder. Output from the zero coefficient eliminator is coded using Huffman coding. Both outputs are combined to form the resulting compressed stream.

Abstract: Interactive radio frequency tags that are responsive to external stimuli to change state are disclosed. The tags preferably include a passive radio frequency transponder, having an antenna, an interface for receiving an external stimulus, and one or more integrated circuits responsive to the external stimulus received at the interface to change the state of the transponder. Also disclosed is a “sensor tag” which changes state in response to a particular environmental stimulus. In addition, either of these “button” or “sensor” features may be combined with an output feature which visually, audibly, tactilely or otherwise signals the state or change of state of an RF tag, or the tag may be designed to produce an output in response to the external stimulus of the RF signal received at the tag's antenna.

Abstract: The estimation of an HRTF for a given individual is accomplished by means of a coupled model, which identifies the dependencies between one or more images of readily observable characteristics of an individual, and the HRTF that is applicable to that individual. Since the HRTF is highly influenced by the shape of the listener's outer ear, as well as the shape of the listener's head, images of a listener which provides this type of information are preferably applied as an input to the coupled model. In addition, dimensional measurements of the listener can be applied to the model. In return, the model provides an estimate of the HRTF for the observed characteristics of the listener.

Abstract: A data-compressed audio waveform is temporally modified without requiring complete decompression of the audio signal. Packets of compressed audio data are first unpacked, to remove scaling that was applied in the formation of the packets. The unpacked data is then temporally modified, using one of a number of different approaches. This modification takes place while the audio information remains in a data-compressed format. New packets are then assembled from the modified data, to produce a data-compressed output stream that can be subsequently processed in a conventional manner to reproduce the desired sound. The assembly of the new packets employs a technique for inferring an auditory model from the original packets, to requantize the data in the output packets.
