    摘要: A method and apparatus for initializing optical recording media is provided that detects the intensity of a reflective light off of an optical recording media and analyzes the initializing condition based on the detected intensity during an initializing process. The light is radiated on a rotating phase-change optical recording medium. The light may be moved in a radial direction of the optical recording medium. The detected intensity of the reflected light may be used to identify crystallized portions and amorphous portions of the optical media. The initialization process can be adaptively controlled to ensure proper initialization. If desired, re-initialization can be limited to those areas detected to be outside of the predetermined parameters.

    摘要: Aspect ratio converting circuits store a digital signal at a first clock rate into a memory, wherein the digital signal represents a picture having a first aspect ratio. In the first mode, the digital signal is retrieved from the memory during one horizontal period on the basis of the first clock rate. In the second mode, in one horizontal period, a portion of the digital signal is retrieved on the basis of a second clock rate related to a conversion ratio between the first aspect ratio and a second aspect ratio of the picture.

    摘要: A method and apparatus for diagnosing or detecting failures or faults in or between circuits such as signal processing circuits of a video camera system. Predetermined test pattern data may be generated on a first or transmitting side (circuit) and discrimination pattern data having substantially the same data pattern as the test pattern data may be generated on a second or receiving side (circuit) in synchronism with the test pattern data. The test pattern data and the discrimination pattern data may be compared. A failure or faulty spot in or between circuits may be determined in accordance with the results of such comparison.
