  • Publication number: 20070257985
    Abstract: A surveillance method periodically detects an image of the area, identifies and tracks each moving object in a succession of the detected images, detects radio frequency emissions from the area and correlates an identified object with a detected radio frequency emission. The method detects events in the tracking of the moving object. The method stores corresponding data optionally including image data in non-volatile memory upon detection of a combination of an event and a corresponding radio frequency emission. The method triggers an alarm such as an audible alarm, a visual alarm, an email, a short text message or a telephone call detection of a combination of an event and a corresponding radio frequency emission.

  • Publication number: 20060140591
    Abstract: Embodiments of the present invention include systems and methods for load balancing audio/video streams to maximize the number of video frames that are actually rendered on a target device, thus giving the user of the target device a higher quality playback experience. Some embodiments are directed to transcoding an audio/video stream into a format that allows additional decoding time on a target device for more complex video sections of the stream. Additional decoding time is gained by duplicating lower complexity video frames in the video stream that precede the complex video sections and temporally expanding the audio stream by a small percentage around each of these load-balanced windows in the video stream. Other embodiments are directed to identifying the more complex video sections in real-time as the stream is being decoded on a target device, and temporally expanding the audio stream to allow more decoding time for these complex sections.

  • Publication number: 20060025159
    Abstract: A system and method for context-based notification of a received transmission. Some illustrative embodiments may be an electronic communication system comprising a radio frequency (RF) receiver, location logic, a central processing unit (CPU), a notification device, and notification software. The RF receiver is adapted to receiver RF transmissions, the location logic is adapted to determine a current location of the electronic communication system, and the notification device is adapted to signal a user that a transmission has been received. The notification software executes on the CPU and causes the CPU to determine whether to activate the notification devices based on the current location of the mobile electronic communication system.

  • Publication number: 20030091325
    Abstract: A device for audio and video playback is operable to receive a digital video signal input or an analog video signal such as a National Television System Committee-standard (NTSC) video signal input through an input connector port of the device. The device may also receive an audio signal input through an audio input connector port. The audio and video playback device includes a storage device for storing audio and video signals in Moving Picture Experts Group-standard (MPEG) format. The audio and video playback device also includes output connector ports operable to provide audio output and video output. A central processing unit in the device receives audio and video input signals from the input connector ports, compresses the audio and video input signals into MPEG format and can store the MPEG-format signals in the storage device. The processor is also operable to retrieve and decompress stored audio and video signals from the storage device and provide output signals to output connector ports.
