Abstract: A method for coordinating a camera array that includes a first camera and a second camera to monitor an object. The first camera stores a parameter related to the object. The first camera identifies an image characteristic in an image of the object based on the parameter when capturing the image of the object. The first camera then determines whether the image characteristic is identified in the image. If the image characteristic is identified in the image, the first camera instructs the second camera to capture an enlargement of the image characteristic.

Abstract: In an audio/video (AV) recording process, an AV recording and playing system and method split an original video signal from a computer into a first original video signal and a second original video signal. The first original video signal is converted to a digital video signal. The second original video signal is displayed on a display device. An analog audio signal is captured and converted to a digital audio signal. The digital video signal and the digital audio signal are compressed to a compressed AV file. In an AV playing process, the system and method retrieve a compressed AV file and decompressed the file into a digital audio signal and a digital video signal. The digital video signal is converted to an analog video signal. The digital audio signal is converted to an analog audio signal.

Abstract: A method is disclosed for jumping tracks on a double-layer optical disk from a first address A on a first data layer to a target address D on a second data layer. According to the method, the first address A where the optical head is currently positioned is read. Then, after jumping to the second data layer, a relative second address B on the second data layer that corresponds to the first address A on the first data layer is read. If the second address B on the second data layer is smaller than the first address A on the first data layer, then the address of the second address B on the second data layer is shifted and a new target address is obtained on the second data layer based on this address shift. A calculation function is performed based on the first address A and the new target address, and then the optical head is moved to the new target address on the second data layer.
