摘要:
A data recording/reproducing apparatus includes a first power source unit which generates necessary electric power signals from a commercial power source, and a second power source unit which generates a necessary electric power signal from the commercial power source. When a user issues an instruction to interrupt the operation of the power source of the apparatus, the generation of the electric power signal of the first power source unit is stopped, and the electric power is supplied to at least two of a control unit for controlling switching of operation states of the apparatus, a reception unit for receiving a manipulation instruction, and a display unit for displaying thereon data relating to the operation state from the second power source unit.

A signal recording/reproducing apparatus includes a first power source unit which generates necessary electric power signals from a commercial power source, a second power source unit which generates a necessary electric power signal from a battery, a recording signal processing unit, and a reproduced signal processing unit. The apparatus further includes time measuring instrument which is supplied with the electric power from the second power source unit, and a charging unit which charges the battery with the electric charges. Whenever the time measuring instrument measures a predetermined time, the generation of the electric power signals from the first power source unit is started, and the battery is charged with the electric charges by the charging unit.

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 performed by a common audio head. At the time of reproduction in the N-ple play mode, the optimum tracking control is performed by a tracking control system by use of an output of the audio head. At the time of completion of recording in the N-ple play mode, a video signal is supplied with a time prolonged corresponding to the delay of scan of a video head from that of the audio head so that a video track is surely overwritten on an audio track. A high-speed fast feed/rewind speed at the time of N-ple play mode is set to a low value as compared with the tape speed at the time of standard play mode, thereby ensuring the detection of an index signal from the magnetic tape in the N-ple play mode.

A recording apparatus of a helical scan system, including a first video head which records video signals on a magnetic tape when a running speed of the magnetic tape is a standard speed and a second video head which records video signals on the magnetic tape when the running speed of the magnetic tape is approximately 1/N of the standard speed, N being an integer larger than 3.
摘要:
A magnetic recording/reproducing apparatus having a capability of allowing contents of records on a magnetic tape to be discriminatively identified and a capability for displaying closed caption includes a tape map memory for storing contents recorded on a tape and a tape map controller. As a manual input facility, a tape map button, a caption button, a play-back button, a stop button and others are provided. Upon loading of a tape undergone recording(s), the tape map button is pushed to display on a monitor screen tape map information concerning the contents of program(s) recorded on the loaded tape, temporal duration(s) of the program(s), and history of play-back of the tape.

摘要:
A character display circuit in which a circuit for generating a character display timing signal in synchronism with vertical and horizontal synchronizing signals controls the frequency of dots constituting a character such that it is an integer multiple of the coding frequency for bits of a closed caption code, character coded data conforming to a format of the closed caption code is generated in synchronism with a predetermined horizontal synchronizing signal during the blanking period of a video signal using dot patterns for encoding character data, and the character coded data is superimposed on the video signal.

During the playback operation for freezing and storing a specific frame of a picture in a memory and thereafter printing the frame, the recording medium is turned reversely for a prescribed amount according to an instruction from a printer in response to the entry of the freeze command in order to accurately search the frame at the entry of the freeze, and thereafter the recording medium is played back in normal mode. The amounts of reverse turn and the successive forward turn in normal playback are counted and compared, and when the difference has become a prescribed value, a freeze signal is produced and the frame of the picture selected by the freeze command is stored in the memory and printed when required. This control method for use in a video print system is designed so that the recording medium is turned reversely for a prescribed amount according to an instruction from the printer and then stopped until the next command is entered.

A video signal processor suitable for use with a VTR, the processor being provided with a circuit for eliminating inserted information signals other than a time code at a stage prior to the addition of a time code signal to the vertical blanking period of a video signal, providing accurate time code reading in a VTR equipped with a circuit for recording or reproducing the time code signal.
摘要:
A character generator and method which requires reduced storage memory space for a character memory by virtue of generating bit fill patterns that fill character borders. The borders are, in turn, generated from partial borders that are local to the starting, ending, and any middle coordinate points of an imaginary baseline roughly drawn along the centerlines of strokes making up the character. As especially applied to Japanese and Chinese character sets, the character generator and method further improve on memory storage savings by separating basic characters from compound characters. The compound characters are then generated in terms of reshaped and repositioned basic characters, thus eliminating the redundancies that would otherwise exist.
