Patent number: 5552833Abstract: A method and system in which television-program table information is transmitted using teletext formats in a coding transmission system. On the reception side, reservation of video recording with an image recording apparatus is effected by making use of the transmitted television-program table information. Reserving a recording time is accomplished using a program recognition device 9 which detects that the television-program table information has been transmitted. Further, a program update recognition device 10, a channel information processing device 11, a date information processing device 12, a time information processing device 13, a program code information processing device 14, and a title information processing device 15 serve to process their respective information in order to display the television program table on a display unit. Once displayed, a television program desired for video recording is selected by a cursor display device and selection device 19.Type: GrantFiled: April 7, 1992Date of Patent: September 3, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hidemi Henmi, Shigeru Takano, Hideto Nakahigashi, Ken Sakamoto

Patent number: 5390027Abstract: Television program information contained in an extracted text broadcast signal is selected and input to a video cassette recording device. The recording program information includes recording times and program titles. The recording device includes a timer for starting the recording of the television program on a tape in accordance with the recording information, an index detector for detecting an index along the tape to identify a section in the tape where the television program is recorded, a rewind controller for rewinding the tape to its initial position, a writing arrangement for writing the recording information of the recorded program together with the index information at the initial position of the tape, and a fast forward controller for advancing the tape to the end of the recorded section identified by the index. The recording information written at the initial position of the tape can be displayed on a screen to indicate the contents of the tape.Type: GrantFiled: July 19, 1993Date of Patent: February 14, 1995Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hidemi Henmi, Shigeru Takano, Hideto Nakahigashi, Ken Sakamoto
