摘要： A device and method for encoding an image into hierarchical codes. Since the quantizing step width of lower hierarchical data having a higher resolution than that of higher hierarchical data is determined, on the basis of the quantizing step widths determined for the higher hierarchical data having a lower resolution, for every prescribed block of hierarchical data, additional codes indicating the characteristics of quantizers can be eliminated. Therefore the compression efficiency at the time of encoding can be improved and the deterioration of image quality can be reduced.

摘要： A tape recorder records and/or reproduces information signals by bringing a magnetic tape into sliding contact with a magnetic head on a rotary head mechanism. This tape recorder comprises a rotary head mechanism including a rotating drum fitted with a magnetic head for bringing the head into sliding contact with running tape, and a fixed drum coaxial with the rotating drum for rotatably supporting the latter; a pair of supporting members rotatably supported on the rotary head mechanism; a pair of capstans rotatably mounted on ends of the supporting members; and a pair of pinch rollers opposed to the corresponding capstans. The pair of supporting members are rotated in accordance with the direction in which the magnetic tape travels. Either one of the capstans is selectively moved toward either one of the pair of the pinch rollers in order to pinch the magnetic tape between the capstan and pinch roller. Further, the capstan and pinch roller cooperate to drive the magnetic tape, thus implementing the switch over in the traveling direction of the magnetic tape.

摘要： A signal encoding device which encodes acoustic signals is provided with a conversion circuit (601) which converts inputted acoustic signals into frequency components, signal component separation circuit (602) which separates the output of the circuit (602) into tone and noise components, tone component encoding circuit (603) which encodes tone-component signals, and noise component encoding circuit (604) which encodes noise-component signals. The encoding efficiency of the signal encoding device is improved without deteriorating the tone quality of the tonal acoustic signals, because the circuit (603) encodes (601) the signal components of the tone-component signals into codes having different code lengths.

摘要： An apparatus comprising a time-series sample buffer (32) for forming inputted signals into blocks; an orthogonal-transformation encoder (33) for converting the signal of every block into spectrum signals; and an entropy encoder (32) for totally or partly encoding the spectrum signals of every block into variable length codes. The entropy encoder (32) has means for setting the upper limit of the number of bits of the signals of every block encoded and outputted, and a circuit (52) for counting the number of bits to stop the output of part of the spectrum signals of a block requiring the number of bits which exceeds the upper limit. The recording or transfer of a part of the spectrum signals of a block requiring the number of bits exceeding the upper limit is impeded, making it possible to reduce the amount of the information which is encoded, recorded or transferred, and decoded.

摘要： Clock marks for extracting clock components are made in advance at regular intervals along the track of a discoid recording medium, and clock components are extracted by detecting these clock marks at the time of rotating the discoid recording medium. Since the clock components are extracted from the definitely and periodically arranged clock marks in such a way, and interpolating clocks in sections between clock marks are generated based on the extracted clock components, highly accurate clocks can be obtained as compared with the case where clocks are extracted from reproduced codes. Therefore, the capacity of the discoid recording medium can be remarkably increased.

摘要： Inputted image signals are coded, for example, by performing prediction encoding, DCT conversion, quantization in predetermined quantization step sizes, and variable-length coding so as to generate first coded data. From the amount of the first coded data per unit of time, for example, per frame or GOP and the total amount of data usable, the amount of codes assigned per frame or GOP is determined. On the basis of this amount of codes assigned, the inputted image signals are coded every given period of time to generate second coded data. Thus variable rate coding in which the coding rate changes every period of time is implemented to provide high-quality images which are uniform as a whole without increasing the quantization step sizes of images even though there are continuous frames whose patterns are complicated, unlike a conventional apparatus. The second coded data thus generated are variable rate ones. Therefore, by recording them on an image recording medium, it is possible to utilize a limited capacity of storage effectively, and prolong the recording time of the image recording medium. Then, from this image recording medium, it is possible to reproduce high-quality images which are uniform as a whole.
摘要翻译：输入图像信号例如通过执行预测编码，DCT转换，预定量化步长的量化和可变长度编码进行编码，以便产生第一编码数据。从每单位时间的第一编码数据的量，例如每帧或GOP和可用数据的总量，确定每帧或GOP分配的代码量。基于分配的这个代码量，输入的图像信号每给定一段时间被编码以产生第二编码数据。因此，实现编码率每个时间周期变化的可变速率编码，以提供整体均匀的高质量图像，而不增加图像的量化步长，即使存在图案复杂的连续帧，这与传统的仪器。这样生成的第二编码数据是可变速率数据。因此，通过将它们记录在图像记录介质上，可以有效地利用有限的存储容量，并延长图像记录介质的记录时间。然后，从该图像记录介质，可以再现整体上均匀的高质量图像。

摘要： An apparatus, method, and system in which a compressed digital signal is derived from a digital input signal (67) by compressing the digital input signal in a selected one of plural compression modes. The digital output signal has a different bit rate in each compression mode, but the digital input signal is received at the same bit rate in all the compression modes. In the method, spectral coefficients are derived from the digital input signal, and are grouped by frequency and by time into bands. Each band has a frequency width, and the frequency width of at least one of the bands is set according to the selected compression mode. The spectral coefficients in each band are quantized to provide quantized spectral coefficients. Finally, the quantized spectral coefficients in each band are included in the compressed digital signal, together with sub information for each band.

摘要： An apparatus for recording and reproducing given data to and from a disc-like recording medium which is rotated by a constant linear velocity (CLV) method. In this apparatus, the rotational speed of a driving means is controlled in accordance with a first rotational speed signal of this means in seek operation in which an optical pickup is shifted to the target position of the disc-like recording medium. When the shift of the optical pickup to the target position is detected by the output of a position detecting means, the rotational speed of the driving means is controlled by a second rotational speed signal which is obtainable from the disc-like recording medium. Immediately after the termination of the seek operation, the disc-like recording medium can be rotated instantaneously in accordance with the second rotational speed signal. In this way, it is possible to materialize an optical disc apparatus such that the time required for the seek operation is shortened to that extent.
