    摘要： A quantizer designed by using human visual sensitivity is disclosed, in which when postprocessing is done after inverse quantization an optimum visual sensitivity function for a system involving the postprocessing is obtained for doing quantization by using that visual sensitivity function.Where the postprocessing that is executed after the inverse quantization consists of a filtering process with a characteristic L(.omega.) (.omega. being the frequency) and a 1:2 interpolation process, denoting the optimum visual sensitivity as the output result by W(.omega.) as shown in FIG. 2, the optimum equivalent sensitivity function W'(.omega.) is given asW'(.omega.)=1/2[L(.omega./2)W(.omega./2)+L(.omega./2+.pi.)W(.omega./2+.pi.)].By using this equivalent sensitivity function W'(.omega.) for the quantizer, it is possible to obtain a visually optimum quantizer designed by using human visual sensitivity.

    摘要： An light emitting diode includes an n-type nitride semiconductor layer, a multiple quantum well layer, a p-type nitride semiconductor layer, a window electrode layer, a p-side electrode, and an n-side electrode, which are stacked in this order. The n-side electrode is electrically connected to the n-type nitride semiconductor layer. The window electrode layer comprises an n-type single-crystalline ITO transparent film and an n-type single-crystalline ZnO transparent film. The p-type nitride semiconductor layer is in contact with the n-type single-crystalline ITO transparent film. The light-emitting diode further comprises a plurality of single-crystalline ZnO rods formed on the n-type single-crystalline ZnO transparent film. The respective lower portions of the single-crystalline ZnO rods have a shape of an inverted taper, which sharpens from the single-crystalline n-type ZnO transparent film toward the n-type nitride semiconductor layer.

    摘要： A monitoring system checks a transmission error of a video/audio signal transmitted from a source (10) to a destination (20A, 20B) by comparing in real time a first feature extracted from the pre-transmission video/audio signal and a second feature extracted from the post-transmission video/audio signal. The transmitted video/audio signal is repeatedly stored for a predetermined period of time. When the system judges that a transmission error has occurred, it transmits the stored video/audio signal to a predetermined address. Thus, the transmission error of the transmitted video/audio signal can be analyzed rapidly and in detail.

    摘要： A video/audio signal transmitted from a transmission source 10 to transmission destinations 20A and 20B is stored repeatedly for a predetermined time period. Thus, for example if the video/audio signal is overwritten at predetermined timing, it is sufficient to have a small storage capacity for the video/audio signal. Also, the video/audio signal on which an error has occurred remains without being overwritten at the time of determination that an error has occurred. Accordingly, by transmitting this signal to a predetermined destination, a detailed error analysis can be made promptly on the basis of the transmitted video/audio signal.

    摘要翻译： 从发送源10发送到发送目的地20A和20B的视频/音频信号被重复存储预定时间段。 因此，例如，如果以预定的定时重写视频/音频信号，则对于视频/音频信号具有小的存储容量就足够了。 此外，发生错误的视频/音频信号在确定发生错误时保持不被覆盖。 因此，通过将该信号发送到预定目的地，可以基于发送的视频/音频信号迅速地进行详细的误差分析。
