A handwriting storing and reproducing method which takes small images including a leading edge for writing and stores the small images in a time sequential manner following a movement of a writing device. The method then reads out the stored small images and overlaps a just read out small image to a previously read out small image so as to obatain a partial image when both small images include portions which include partial handwritings coincident to one another. Thereafter, the method overlaps ...

A reproducing apparatus includes a first device for reproducing a signal of a run-length-limited code from a recording medium. A transversal filter subjects the signal reproduced by the first device to a partial-response waveform equalization to generate an equalization-resultant signal. The partial-response waveform equalization depends on tap coefficients. A second device operates for detecting whether or not the signal reproduced by the first device corresponds to a zero-cross point, and gene...

In a reproducing apparatus of the present invention, an input audio signal is divided into bands and an envelope value of each band is measured. Based on a change of the envelope value, a predetermined sound source is superimposed. Further, according to the envelope value of a reproduced audio signal, a tempo of reproduced music is detected and animation representation is changed in synchronism with the detected tempo. Further, a rhythm box is reproduced in synchronism with the detected tempo an...

An ACS of a Viterbi decoder generates status data that an SMU represents a status transition corresponding to the maximum likelihood status transition selected corresponding to each read clock pulse. A merge block generates decoded data corresponding to status data. A timing generator generates timings of a leading edge and a trailing edge of a reproduced RF signal corresponding to status data. A PEC generates a phase error signal PE corresponding to a reproduced signal value sampled at these th...

In a recording/reproducing apparatus and a reproducing apparatus based on a helical scan system for recording or reproducing a video signal and an audio signal on or from a magnetic tape by use of a magnetic head assembly mounted on a rotary drum, the recording/reproduction of an audio signal in both a standard play mode with a tape speed equal to a standard speed and a long play mode or N-ple play mode with a tape speed N times (N: an integer not smaller than 4) as high as the standard speed is...

In a magneto-optic disc apparatus corresponding to six-value four-status Viterbi decoding method, an RAA has 12 registers so as to separately adapt amplitude reference values for an address portion and amplitude reference values for a data portion on a magneto-optic disc. Normally, stored values of the registers at the time a reproducing operation has been just completed are used for initial values for an adapting process in the next reproducing operation. On the other hand, when data cannot be ...

In a Viterbi decoder, an SMU is used instead of a PMU. The SMU has four status memories that process a status data value composed of a plurality of bits that represent a status at a time. The status memories generate a sequence of four status data values. A merge block generates decoded data corresponding to the four status data values, detects mismatches of four status data values, and generates a mismatch detection signal NM. The number of mismatches is counted corresponding to the mismatch de...

In a reproducing apparatus for reproducing audio data, a central control section includes detection means for detecting playlists of plural kinds of formats, and detection means for detecting audio data not associated with playlists. The central control section reads out audio data from an audio data storage section, and discriminating the format of the audio data to detect playlists. In addition, the central control section detects the presence/absence of audio data not associated with playlist...

A reproducing apparatus is arranged to reproduce from a recording medium a data string including image data and motion data indicative of motion of an image related to the image data, and to control the speed of reproduction of the image data according to the motion data included in the data string reproduced.

A reproducing apparatus for reproducing information from recording elements formed with very small pits on a planar surface. The reproducing apparatus includes a probing unit positioned at a very small distance apart from the surface of the recording element and a scanning unit for scanning the probing unit at a very small distance apart from the surface of the recording element. The reproducing apparatus also includes a detecting unit connected to the probing unit and the recording element resp...
