Patent number: 6263151Abstract: 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.Type: GrantFiled: June 4, 1998Date of Patent: July 17, 2001Assignee: Hitachi, LTDInventors: Hideo Nishijima, Shoji Ohno, Kouji Minabe, Katsuyuki Watanabe

Patent number: 5541663Abstract: 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.Type: GrantFiled: May 12, 1994Date of Patent: July 30, 1996Assignee: Hitachi, Ltd.Inventor: Shoji Ohno

Patent number: 5305433Abstract: 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.Type: GrantFiled: September 28, 1990Date of Patent: April 19, 1994Assignee: Seiko Epson CorporationInventor: Shoji Ohno

Patent number: 5251074Abstract: 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.Type: GrantFiled: April 12, 1990Date of Patent: October 5, 1993Assignee: Hitachi, Ltd.Inventors: Kentaro Hamma, Yasunori Kobori, Hiroyuki Kimura, Yoshinori Okada, Shoji Ohno, Osamu Numata, Kotaro Kawamura, Hideo Nishijima, Naohiro Ozawa
