ABSTRACT:
A video and audio compression and decompression system includes a reconfigurable compact camera communicating with a computer system to permit the camera to execute one of several types of compression modules. The camera includes first and second types of memory. The first type of memory is made of smaller ROM-type memory cells and is used for storing computer-executable video-data-compression subprograms. The second type of memory is made of larger RAM-type memory cells and stores the compression program. A download circuit on the camera is configured to receive transmitted data representing the data compression program and to store the transmitted data in the second memory. A selection is made of the stored subprograms corresponding to the data representing the compression program. An image reader including a data generation circuit captures the external image and generates data representing the image. A processor executes the data representing the computer-executable program and the selected ones of the stored subprograms to generate compressed data, and the compressed data is transmitted from the camera.
