  • Patent number: 6363114
    Abstract: A signal coding method and apparatus enables effective coding of a predetermined time segment of a video signal with a variable bit rate at real time (one-path) into a total coding bit amount of a constant data capacity. A coding difficulty calculator 13 determines a coding difficulty of an input signal for each unit time. An allocation bit amount calculator 14 interrelates an allocation data amount with a coding difficulty for each unit time standardized in advance using an ordinary input signal of the type to which the input signal belongs, so as to obtain a reference value of the allocation data amount for each unit time interrelated with the coding difficulty supplied from the coding difficulty calculator 13. This reference value of the allocation data amount is modified by a controller 15 into an actual allocation data amount, according to which the input signal is coded by a moving picture image coding apparatus 18, so as to create coded data.

  • Patent number: 6356304
    Abstract: An image which is seen as a natural feeling can be attained in such a manner that a resolution of a photographed image is kept substantially constant irrespective of any variation in condition of an optical system such as an iris diaphragm diameter and a zoom position. For example, in the case that it is adapted for an iris diaphragm diameter, an MTF corresponding to a variation of an iris diaphragm diameter is measured (FIG. 6A) and then a gain of an output of an aperture control circuit capable of canceling a reduction of high frequency component of the image signal corresponding to the measured MTF (FIG. 6B). Then, an iris diaphragm diameter varied during a photographing operation is detected, a gain set in response to the detected iris diaphragm diameter is applied to the aperture control circuit, thereby a control is carried out such that an amplitude of the high frequency component of the brightness signal (FIG. 6C) being kept substantially constant without having any relation with the iris diaphragm.

  • Patent number: 6356595
    Abstract: A decoding method for use in a communications system employing a communication channel in which a message is convolutionally encoded by a base station encoder and transmitted to a remote terminal during a time slot allocated to at least that remote terminal. The encoder is not completely reset immediately prior to the allocated time slot such the encoder state is unknown at the onset thereof. The decoding method includes assigning a most likelihood probability for an initial encoder state as being one of a number of predetermined encoder states; and, convolutionally decoding ensuing bits of the message based on the assumption of the initial encoder state as one of the predetermined states. The method affords low error rate decoding, and allows for improved power conservation by a mobile station, since the mobile station need not awaken significantly prior to its allocated time slot. Preferably, a Viterbi decoder is used to perform the convolutional decoding.

  • Patent number: 6347185
    Abstract: A recording apparatus configured to receive analog video and audio signals, digitize and compress the same, and record the compressed audio and video signals on a digital recording medium such as an optical disk. As the audio and video signals are received and recorded, time segments of the audio signals are analyzed for certain features such as whether the time segment corresponds to instrumental music, vocal music or conversational speech. A table of contents is then generated corresponding to the feature analysis and digitally stored on the storage medium. As a result, the recorded audio is characterized over time, e.g., on a frame by frame basis. A high degree of versatility is thereby provided in the playback process, such as the ability to skip portions having certain audio types or to quickly scroll to desired portions of the recorded audio programs. Reproducing apparatuses enable the user to selectively reproduce segments of the recorded audio and video.

  • Patent number: 6341103
    Abstract: A slide-feed drive part (27) uses a stepping motor as a slide-feed motor for changing the position of a optical pick-up (3) with respect to the rotation surface of an optical disk (1), and has a micro-controller (31) provided therein and a slide-feed motor controller (32) both for correcting drive current waveforms to drive the stepping motor. Therefore, by correcting the motor driving waveforms, the optical pick-up (3) can be linearly moved with respect to the rotation of the slide-feed motor (14). It is thereby possible to do away with a position sensor and make a fine positional control of the optical pick-up (3) with no variation. As a result of this, it is possible to provide an optical disk driving apparatus, an optical disk driving method, and an optical disk apparatus, which enhances the linearity of the rotation of the motor with a simple construction.
