Abstract
Abstract A video signal recording apparatus for recording a video signal composed of a plurality of programs and control data on a recording medium, comprises: first time code generating circuit for generating first time code data having a user's bit area in which information data relating to the contents of the program are formed; inserting circuit for inserting the first time code data into predetermined horizontal period in a vertical blanking interval of the video signal; first recording circuit for recording the output signal of the inserting circuit on a video track of the recording medium; second time code generating circuit for generating second time code data having a user's bit area in which stop control data used for controlling the transport of the recording medium are formed; and second recording circuit for recording the second time code data on a longitudinal track of the recording medium such that the stop control data are positioned at a predetermined location of the longitudinal track corresponding to a cue point of the video signal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
A video signal recording apparatus for recording a video signal composed of a plurality of programs and control data on a recording medium, comprising: first time code generating means for generating first time code data having a user's bit area in which information data relating to the contents of said program are formed; inserting means for inserting said first time code data into at least one predetermined horizontal period in a vertical blanking interval of said video signal; first recording means for recording the output signal of said inserting means on a video track of said recording medium; second time code generating means for generating second time code data having a user's bit area in which stop control data used for controlling the transport of said recording medium are formed; and second recording means for recording said second time code data on a longitudinal track of said recording medium such that said stop control data are positioned at a predetermined location of the longitudinal track corresponding to a cue point of said video signal.
Claim 2
Dependent Claim
174 words
A video signal recording apparatus for recording a video signal composed of a plurality of programs and control data on a recording medium, comprising: first time code generating means for generating first time code data having a user's bit area in which information data relating to the contents of said program are formed; inserting means for inserting said first time code data into at least one predetermined horizontal period in a vertical blanking interval of said video signal; first recording means for recording the output signal of said inserting means on a video track of said recording medium; second time code generating means for generating second time code data having a user's bit area in which stop control data used for controlling the transport of said recording medium are formed; and second recording means for recording said second time code data on a longitudinal track of said recording medium such that said stop control data are positioned at a predetermined location of the longitudinal track corresponding to a cue point of said video signal.
Claim 3
Dependent Claim
39 words
A video signal recording apparatus according to claim 1, wherein each of said programs consists of first video signal not used, second video signal used, third video signal not used and block burst signal formed serially in this order.
Claim 4
Dependent Claim
32 words
A video signal recording apparatus according to claim 2, wherein said information data relating to the contents of said program are inserted in the vertical blanking intervals of said second video signal.
Claim 5
Dependent Claim
16 words
A video signal recording apparatus according to claim 3, wherein said information data are inserted repeatedly.
Claim 6
Dependent Claim
38 words
A video signal recording apparatus according to any one of claims 1 to 4, wherein said first time code generating means includes means for forming user control code in said user's bit area of said first time code.
Claim 7
Dependent Claim
126 words
An information signal reproducing apparatus for reproducing an information signal having a plurality of programs composed of video and audio signals recording on an information track of a recording medium including a longitudinal track additional to said information track and on which information data relating to the contents of said program and stop control data, said apparatus comprising: reproducing means for reproducing the data recording on said longitudinal track, means for displaying said information data reproduced by said reproducing means, stop control means for stopping the transport of said recording medium in response to said stop control data reproduced by said reproducing means, and control means for controlling said displaying means such that the display information data are modified in response to said stop control data.
Claim 8
Dependent Claim
126 words
An information signal reproducing apparatus for reproducing an information signal having a plurality of programs composed of video and audio signals recording on an information track of a recording medium including a longitudinal track additional to said information track and on which information data relating to the contents of said program and stop control data, said apparatus comprising: reproducing means for reproducing the data recording on said longitudinal track, means for displaying said information data reproduced by said reproducing means, stop control means for stopping the transport of said recording medium in response to said stop control data reproduced by said reproducing means, and control means for controlling said displaying means such that the display information data are modified in response to said stop control data.
Claim 9
Dependent Claim
121 words
An information signal reproducing apparatus according to claim 6, wherein second time code data are inserted in vertical blanking intervals of said video signal, said second time code data having a user's bit area in which control code data relating to the contents of said program are formed, and further comprising second reproducing means for reproducing said information signal from said information track, control code data extracting means for extracting said control code data from the information signal reproduced by said second reproducing means, converting means for converting said reproduced information signal to a desired form of signal, and mode control means for controlling the mode of said desired form of said converting means in response to said control code data.
