摘要： An echo canceler makes it possible to adaptably control a power of speech reception voice and to reduce distortion of a voice output from a speaker. The echo canceler has a basic structure includes a power control section controlling a power for a speech reception voice, a first filtering section removing a particular component from an output of the power control section, an echo canceling section removing echo components of a speech reception voice, which are added to a speech transmission voice, a second filtering section filtering particular components of the speech reception and transmission voices, and a state judgement section judging existences of the speech reception and transmission voices from an output of the second filtering section and controlling a power attenuation amount of the power control section based on the judgement result.

摘要： For a plurality of digital video signals whose frame frequencies are different, a pixel number converting circuit to convert the number of pixels is provided so that differences of the frame frequencies are replaced to differences of the numbers of pixels and a plurality of digital video signals whose frame frequencies are different can be processed by a common clock frequency. The frame frequency is detected by a frame frequency value decoder and the number of pixels in the horizontal direction of the pixel number converting circuit is properly set in accordance with the frame frequency. As mentioned above, if the differences of the frame frequencies are replaced to the differences of the numbers of pixels and the images are converted into the image in which the frame frequencies are the same and the numbers of pixels are different, the frame frequencies are equalized and the signals can be processed by the same clock.

摘要： When a digital broadcast receiver selects a channel and thereby changes an MPEG picture stream, a video decoder starts a decoding operation in response to an instruction to start decoding. When a predictive coded picture includes an intra slice and an intra macroblock, the video decoder decodes the intra slice and the intra macroblock of the predictive coded picture without waiting for an intra picture to be decoded. When a macroblock to be referred to has previously been decoded, the video decoder further decodes a non-intra slice and a non-intra macroblock of the predictive coded picture by using a decoding result of the macroblock to be referred to. Thus, when changing the channel, for example, it is possible to quickly obtain output picture data, shorten interruption of the pictures, and check a picture of the next channel in a short time.

摘要： The present invention provides an acoustic echo canceler for use in a telephone set having a handsfree conversation function. This acoustic echo canceler simultaneously achieves both the stabilization and speedup of an estimation operation and also attains the more improvement of speech quality. Moreover, the present invention provides a handsfree telephone set employing this acoustic echo canceler. Furthermore, this acoustic echo canceler is operative to cancel an echo generated by inputting an output of an acoustic device to itself substantially simultaneously with the outputting the output thereof. Further, this acoustic echo canceler comprises an adaptive filter for performing an operation of estimating the frequency characteristic and the phase characteristic of a part, whose frequency characteristic and phase characteristic vary, on an acoustic path and a fixed coefficient filter for simulating a part, whose frequency characteristic and phase characteristic are fixed, on the acoustic path.

摘要： To reduce the magnetic flux leakage through the gap between magnetic pole teeth of an armature so as to reduce the magnetic attraction force generated between the armature and a needle, an armature unit is provided with two magnetic poles, on the top of which are magnetic pole teeth protruding toward the opposing magnetic pole, where the magnetic pole teeth of the magnetic pole are arranged at two heights, upper and lower, and the magnetic pole teeth of the opposing magnetic pole are arranged at two heights, upper and lower, so that the magnetic flux flows upward and downward alternately between the upper and lower magnetic pole teeth. The needle equipped with permanent magnets moves relatively in the gap between the upper and lower magnetic pole surfaces of the armature unit.
