摘要： A musical tune playback control apparatus adapted to a music playback apparatus performs prescribed musical tune playback controls on a digital audio medium (or a digital storage medium, e.g., a CD and a MD) in association with a storage device such as a hard disk drive. Musical tune data recorded on digital audio media satisfying prescribed conditions are automatically selected and are transferred to the storage device, thus allowing the user to easily create a musical tune collection or an album collection suiting the user's preferences. Prescribed conditions are described in such a way that musical tune data are reproduced over a prescribed time or more, or musical tune data are repeatedly reproduced a prescribed number of times or more, for example. Thus, it is possible to reduce a user's burden to perform troublesome operations in selecting musical tune data suiting the user's preferences.

摘要： An automatic playing system creates a feedback control loop for the keys incorporated in an acoustic piano; key sensors, which are provided under the front portions of the keys, informs a motion controller of current positions, and the motion controller periodically compares the current position and a current velocity with a target position on a reference trajectory and a target velocity to see whether or not a positional deviation and a velocity deviation occur; when the motion controller finds the deviations, the motion controller multiplies the deviations by a position gain and a velocity gain for determining an increment or decrement of the duty ratio of driving signals, and supplies the driving signals to the solenoid-operated actuators so as to accelerate or decelerate the keys; the gain is variable depending upon the key motion so that the actual key trajectory becomes close to the reference trajectory.

摘要： An automatic player piano is equipped with solenoid-operated pedal actuators for driving the pedals in a playback; since a large quantity of induction is coupled to the solenoid, the driving signal is delayed due to long time constant so that the pedals behave differently from those in the original performance; a controller, which is incorporated in the automatic player, firstly determines a target mean current of the driving signal to be theoretically required for the reproduction of the pedal motion, and a temporary means current twice as much as the target mean current at the maximum; the controller supplies the driving signal at the temporary mean current to the solenoid in an early stage of each cycle, and, thereafter, recovers the driving signal to the target mean current so that the pedal motion becomes close to that in the original performance.

摘要： An automatic player piano includes keys driven for the angular motion through a hybrid feedback control loop; a controller, a key position sensor, a plunger velocity sensor and a solenoid-operated key actuator form parts of the hybrid feedback control loop for each key, and a current key position and a plunger velocity are reported to the controller; the controller determines a series of target position or a reference trajectory and a target velocity, and periodically compares a composite current position and a composite current velocity, which are determined on the basis of the current key position and current plunger velocity, with the target position and target velocity to see whether or not the key travels on the reference trajectory; if the answer is negative, the controller adjusts the driving signal to a proper duty ratio so as to force the key to travel on the reference trajectory.

摘要： An automatic player piano is a combination between an acoustic piano and an electronic system serving as a recorder and an automatic player; while a user is fingering a piece of music on the acoustic piano, the player strongly depresses some keys and softly depresses other keys so as to give artistic expression to the tones, and the depressed keys give rise to hammer motion at different values of hammer velocity; since the hammer velocity is proportional to the loudness of tones, the controller is expected exactly to determine the hammer velocity; the hammers travel on linear trajectories and parabolic trajectories depending upon the hammer velocity so that the controller estimates the hammer velocity by using different methods, whereby the controller can produce music data codes exactly expressing the tones to be produced.

摘要： A music data modifier receives pieces of original music data from a master hybrid piano, and partially modifies the pieces of original music data to pieces of modified music data for a slave hybrid piano; each piece of original music data contains a series of values of a piece of motion data expressing continuous motion of the associated key, a series of values of a piece of time data expressing each expressing a time to obtain the associated value of the motion data and a piece of identification code expressing the key number assigned to the key; even if the music data modifier changes the piece of identification data from the key number to another key number, the piece of motion data still expresses the continuous motion of the key so that the slave hybrid piano exactly reproduce the key motion.

摘要： Black/white keys are selectively moved by key actuators energized with a driving signal in a playback mode, and plunger sensors, which are provided inside of the key actuators, report the measured values of the keystroke to a motion controlling section; since the measured values contain error due to the deformation of the keys, the motion controlling section estimates true values or estimated values of the keystroke by dividing the sum of products between the measured values and weighting factors by a normalizing constant, and compares the estimated values with target values to see whether or not the keys exactly travel on reference trajectories; if the answer is negative, the motion controlling section varies the duty ratio of the driving signal so as to accelerate or decelerate the keys.

摘要： A video signal shuffling device forms a segment with blocks having a given offset value in horizontal and vertical directions from a given starting point uniquely determined on the screen, the offset value being identical in every region. The segment is formed in a unit of one frame or two frames. The shuffling device divides one frame comprising blocks into a plurality of regions. A coding device determines a final priority as well as a final quantizer thereby quantizing a segment and providing the segment with a variable-length-coding based on a first priority, coding-quantity obtained from a plurality of quantizers, second priority and a quantizer. A coding device and its decoder, the coding device carries out a hierarchical coding by only a motion vector in a compressed stream at a lower resolution side and by agreeing a motion detected and a DCT block size with a size on the screen.
