摘要： An automated system and method for producing videos using expert video production rules. The automated video production system and method of the present invention is particularly well-suited for the online publishing of lectures. The system of the present invention includes a camera system for capturing the lecture, such as an audience-tracking camera and a non-intrusive lecturer-tracking camera. Moreover, each camera may be controlled by a cinematographer. Tracking of a subject is performed using a history-based, reduced-motion tracker that sets up a camera shot based on the subject's movement history and leaves the shot fixed until the camera is switched. The system also includes a virtual director module having a probabilistic finite state machine (FSM) module that uses probabilistic rules and the expert video production rules to determine a current camera view.

摘要： A program distribution system includes a plurality of set-top boxes that receive broadcast programming and segmentation data from content and information providers. The segmentation information indicates portions of programs that are to be included in skimmed or condensed versions of the received programming, and is produced using manual or automated methods. Automated methods include the use of ancillary production data to detect the most important parts of a program. A user interface allows a user to control time scale modification and skimming during playback, and also allows the user to easily browse to different points within the current program.

摘要： Audio/video programming content is made available to a receiver from a content provider, and meta data is made available to the receiver from a meta data provider. The meta data corresponds to the programming content, and identifies, for each of multiple portions of the programming content, an indicator of a likelihood that the portion is an exciting portion of the content. In one implementation, the meta data includes probabilities that segments of a baseball program are exciting, and is generated by analyzing the audio data of the baseball program for both excited speech and baseball hits. The meta data can then be used to generate a summary for the baseball program.

摘要： Indications of which participant is providing information during a multi-party conference. Each participant has equipment to display information being transferred during the conference. A sourcing signaler residing in the participant equipment provides a signal that indicates the identity of its participant when this participant is providing information to the conference. The source indicators of the other participant equipment receive the signal and cause a UI to indicate that the participant identified by the received signal is providing information (e.g. the UI can causes the identifier to change appearance). An audio discriminator is used to distinguish between an acoustic signal that was generated by a person speaking from that generated in a band-limited manner. The audio discriminator analyzes the spectrum of detected audio signals and generates several parameters from the spectrum and from past determinations to determine the source of an audio signal on a frame-by-frame basis.

摘要： A system and method for teleconferencing and recording of meetings. The system uses a variety of capture devices (a novel 360° camera, a whiteboard camera, a presenter view camera, a remote view camera, and a microphone array) to provide a rich experience for people who want to participate in a meeting from a distance. The system is also combined with speaker clustering, spatial indexing, and time compression to provide a rich experience for people who miss a meeting and want to watch it afterward.

摘要： An automated camera management system and method for capturing presentations using videography rules. The system and method use technology components and aesthetic components represented by the videography rules to capture a presentation. In general, the automated camera management method captures a presentation using videography rules to determine camera positioning, camera movement, and switching or transition between cameras. The videography rules depend on the type of presentation room and the number of audio-visual camera units used to capture the presentation. The automated camera management system of the invention uses the above method to capture a presentation in a presentation room. The system includes a least one audio-visual (A-V) camera unit for capturing and tracking a subject based on vision or sound. The (A-V) camera unit includes any combination of the following components: (1) a pan-tilt-zoom (PTZ) camera; (2) a fixed camera; and (3) a microphone array.
