Abstract: A compact disk-interactive (CD-I) system which can reproduce CD-ROMs programmed using different codes as well as general compact disks for use as a multimedia appliance. Besides a first CPU for controlling the operation of the system, a CD drive, and video and audio output devices, the CD-I system includes a second CPU for decoding data from a CD-ROM, a memory for storing the operation system of the second CPU, a bus arbitration logic for arbitrating the operation priority of the system bus between the first and second CPU, and a programmable array logic for controlling the bus arbitration logic in accordance with the code type of the reproduced data.

Abstract: The present invention relates generally to a method and apparatus for detecting a shaking condition of a camcorder, and temporarily halting or suspending operation of the camcorder while the camcorder is shaking excessively. The present invention employs counters that are incremented by a mercury switch shaking detector mounted on the camcorder. The count is compared to a predetermined count limit. If the count exceeds the count limit, an excessive shaking condition is established. Recording of the camcorder is temporarily halted accordingly. Further, the counters are reset after predetermined time intervals.
