Abstract: A reference block is divided (at 6) in the horizontal direction into small blocks, and is also divided in the vertical direction into small blocks. Feature values representing each of the small blocks formed from the reference block are obtained (at 8A, 8B). Similarly, a check block is divided (at 7) in the horizontal and vertical directions into small blocks and feature values representing the small blocks formed from the check block are obtained (at 9A, 9B). The feature values in the horizontal direction of the reference and check blocks are compared (at 10A), and the feature values in the vertical direction of the reference and check blocks are compared (at 10B). The results of the two comparisons comprise an evaluation value by which the degree of matching of the reference and check blocks is evaluated. The check block is moved (by 14) throughout a predetermined search range, and the process is repeated for each position of the check block. A motion vector is produced (by 12) between the reference block and the check block position at which the check block best matches the reference block.

Abstract: In step S1, the capacity of the area (remaining quantity) of a disk in which information can be recorded is read, and the remaining quantity is displayed in step S2. After a user input the recording time of information to be recorded and the recording capacity w for the recording, an average transmission rate R1 is calculated from expression R1 = w/t - alpha in step S4. The rate alpha is the transmission rate for transmitting signals other than a video signal, such as an audio signal, attached to the video signal. Data obtained by applying a DCT treatment to the video data is quantized with a quantization width corresponding to the average transmission rate R1 and this data is intermittently recorded on the disk.

Abstract: 33528 A video tape recording apparatus having a tape guide drum with a cylindrical outer surface for guiding a magnetic tape in a helical fashion on the outer surface, and a pair of rotary magnetic heads rotating at a predetermined speed and provided in association with the tape guide drum for scanning skewed parallel tracks on the magnetic tape is specially adapted to perform after recording or dubbing. Each of the tracks is formed having a length to accommodate a pair of audio portions and a center video portion provided between the pair of audio portions. Rotational angles of the rotary magnetic heads corresponding to the length of the audio portions and the center video portion are expressed as follows, ea + ev = eb + .THETA.v = 180.degree. where .THETA.a and .THETA.b correspond to the audio portions and .THETA.v corresponds to the center video portion, respectively. In the case of audio after recording, selected audio portions are left blank during the initial recording operation and the after recording audio signal is recorded therein at a later time.

Abstract: A magnetic erasing head (5) of a double effective gap type which has gaps (g1,g2) different in width to each other, a magnetic center core (7) positioned between the gaps and a winding (6) for inducing a magnetic flux. An erasing signal is supplied to the winding (6), the wavelength of the erasing signal having a predetermined relationship relative to a length of the magnetic center core so that the residual magnetism induced in the tape coating by the fluxes generated across the gaps (g1,g2) forms closed flux paths extending depthwise into the coating.

Abstract: An FM multiplex audio system wherein either stereo signals or signals of two languages can be simultaneously transmitted and where switch means are provided so as to selectively delay either of the language signals so that the listener will hear a first language and then after a delay a second language. Means are also provided for muting either of the language signals if desired.

Abstract: PROBLEM TO BE SOLVED: To realize high reliability and a high speed access at processing of computer data by including plurality of operating modes with different error processing modes at recording or reproduction of data into a plurality of operating modes containing operating modes with different number of disk rotational speeds. SOLUTION: A CPU-B 204 receives a 'SET AV CONFIGURATION' command issued from a host via a PC card interface. The CPU-B 204 sets a disk rotational speed to an SPM control section 212 according to an instruction of a 'Bit 1' of a 'word 0' of the command and also sets a data rate in response to the number of disk revolutions to a recording channel 206 and a reproduction channel 207. In the case of 'Bit 1=0', it indicates a Home mode, where the number of disk revolutions is set high similarly to the case with an existing HDD resulting in assuring a high data transfer speed. Furthermore, in the case of 'Bit 1=1', it indicates a Portable mode.

Abstract: PURPOSE:To stabilize the quality of copy magnetic recording medium regardless of fluctuation in the value of recording current at the time of recording on a mother magnetic recording medium or fluctuation in the strength of transfer bias field at the time of transfer. CONSTITUTION:In order to record information on a mother tape, the current flowing through a recording magnetic head is set as follows. At first, an optimal recording current Iorc is determined so that the level of reproduced output signal is maximized. In other words, information is recorded on the mother tape by altering the recording current sequentially and the level of reproduced output signal from the mother tape is measured in order to determine the optimal current Iorc for maximizing the level of reproduced output signal. A recording current is then set equal to the sum of the optimal recording current Iroc and a predetermined current alpha. Fluctuation in the level of reproduced output signal from a copy tape due to fluctuation in the recording current value at the time of recording of the mother tape or in the strength of transfer bias field at the time of transfer is suppressed by setting the recording current higher than the optimal recording current Iroc.

Abstract: PURPOSE:To enable efficiently looking overlapping programs in series. CONSTITUTION:The record of a program B on a magnetooptical disk is started at the time t2 while looking the broadcasting of the program A by a television. When the program A is finished at the time t3, the recording is made to continue as it is and also a reproduction with N-fold speed is started by a pickup which is independently provided. When the reproduction fetches up with the recording operation at the time t4, the reproducing operation of the magneto- optical disk is stopped, then the program B outputted from a tuner is outputted as it is and displayed.
