Systems and methods for the processing of images over bandwidth-limited transmission interfaces, such as processing of high resolution video images over standard analog video interfaces, using multi-stream and/or multi-resolution analog methodology. The disclosed systems and methods may also be implemented to provide video resolutions across standard analog video interfaces in a manner that supports digital capture and imaging techniques to obtain useful information from digitally zoomed and enhanced video.

Systems and methods for multi-stream image processing

Systems and methods that may be employed to visually locate and/or track objects equipped with active RFID tags. The disclosed systems and methods may employ an articulated camera/s, such as closed circuit television ('CCTV') or other suitable type of articulated camera/s, that is equipped with an antenna array.

Systems and methods for location of objects

A system for routing media content files having different format characteristics to a plurality of clients over a communication network includes a content translation router. The content translation router is capable of retrieving the content files. In addition, the content translation router includes processing modules for concurrently modifying content files having differing format characteristics to be compatible for transmission over the communication network for viewing at different ones of the clients.

System and method for processing content

A system and method for high resolution video conferencing is shown and described. A transmitting station and a receiving station including video cameras or sensors, a plurality of microphones and speakers, video, audio and communication processing engines are disclosed. Video is processed and transferred through the system allowing for multiple video streams to be produced and audio is processed and transferred through the system allowing for sound to be played back with an indication of position in relation to the videoconferencing system.

System and method for high resolution videoconferencing

Systems and methods for the processing of images over bandwidth-limited transmission interfaces, such as processing of high resolution video images over standard analog video interfaces, using multi-stream and/or multi-resolution analog methodology. The disclosed systems and methods may also be implemented to provide video resolutions across standard analog video interfaces in a manner that supports digital capture and imaging techniques obtain useful information from digitally zoomed and enhanced video.

In accordance with the present invention, a system and method for computing a location of an acoustic source is disclosed. The method includes steps of processing a plurality of microphone signals in frequency space to search a plurality of candidate acoustic source locations for a maximum normalized signal energy. The method uses phase-delay look-up tables to efficiently determine phase delays for a given frequency bin number k based upon a candidate source location and a microphone location, thereby reducing system memory requirements. Furthermore, the method compares a maximum signal energy for each frequency bin number k with a threshold energy E(k) to improve accuracy in locating the acoustic source.

Systems and methods for multi-resolution image processing

Optical block assemblies having single or multi-stage folded light path lens assemblies that may be implemented to allow an optical block assembly to occupy significantly less space and/or present reduced rotational inertia to an electrical articulating mechanism. An optical assembly may be so configured for closed circuit television applications or in any other suitable video imaging application including, but not limited to, applications involving non-articulated or articulated cameras such as normal filming (e.g., motion picture film cameras or studio television cameras), camcorders, military targeting or imaging devices, etc.

Optical block assembly

A conferencing system with improved audio response, interface, and audio source tracking capabilities includes a low-profile base unit capable of capturing and processing audio and video information and of interfacing with other external devices, and a separate network interface device coupled to the low-profile base unit and capable of connecting to a network, producing audible sound, regulating power, and housing removable interface circuitry.

Conferencing system with integrated audio driver and network interface device

An electromagnetic circuit that may be advantageously employed in an articulated camera, such as a CCTV camera, as a part of a servo mechanism to directly drive the camera and optical lens assembly, for example, in the pan and/or tilt axes. In one embodiment, the coil assembly of the servo mechanism may comprise four separate coils that rotate about the center of the ring shape of a single one-piece ring-shaped permanent magnet that has been pre-magnetized in two pair of opposing polarities. The magnet assembly that includes the magnet ring, may be bonded to a circular plate made of ferrous metal.

Electromagnetic circuit and servo mechanism for articulated cameras

A system and method for acoustic source location using a horizontal and vertical microphone array. Tilt sensors are provided within each array to allow full determination of the tilt of each array. Based on the acoustic source location results, an image capture device may be maneuvered to focus in the direction of the acoustic source location.
