Abstract
Abstract Apparatus for recording or reproducing a video signal has a user-controlled starting point setting device enabling a user of the apparatus to set a time code representative of a recording starting point. A user-controlled frame number setting device enables the user to set the number of frames to be recorded. A frame memory records an arbitrary one frame of an input video signal. A controller calculates a time code representative of a recording ending point on the basis of the time code of the starting point set by the user and the number of frames set by the user and controls the frame memory so that the video signal written in the frame memory is repeatedly read out and recorded during a period from the recording starting point to the recording ending point.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
An apparatus for recording a video signal comprising: user-controlled starting point setting means enabling a user of the apparatus to set a time code representative of a recording starting point; user-controlled frame number setting means enabling the user to set the number of frames to be recorded; a frame memory in which an arbitrary one frame of an input video signal is recorded; and control means for calculating a time code representative of a recording ending point on the basis of the time code of said starting point set by the user and the number of frames set by the user and controlling said frame memory so that the video signal written is said frame memory is repeatedly read out and recorded during a period from the recording starting point to the recording ending point.
Claim 2
Independent Claim
135 words
An apparatus for recording a video signal comprising: user-controlled starting point setting means enabling a user of the apparatus to set a time code representative of a recording starting point; user-controlled frame number setting means enabling the user to set the number of frames to be recorded; a frame memory in which an arbitrary one frame of an input video signal is recorded; and control means for calculating a time code representative of a recording ending point on the basis of the time code of said starting point set by the user and the number of frames set by the user and controlling said frame memory so that the video signal written is said frame memory is repeatedly read out and recorded during a period from the recording starting point to the recording ending point.
Claim 3
Dependent Claim
52 words
The apparatus according to claim 1 further comprising picture generating means for generating a video signal of an arbitrary fixed picture, time code generating means for generating a time code signal and control means for reformatting a recording medium by recording said video signal of fixed picture and said time code signal.
Claim 4
Dependent Claim
16 words
The apparatus according to claim 2 wherein said picture generating means generates a background color signal.
Claim 5
Dependent Claim
14 words
The apparatus according to claim 1 wherein said recording medium is a magnetic tape.
Claim 6
Dependent Claim
22 words
The apparatus according to claim 4 wherein a recording on said recording medium is carried out at every predetermined number of frames.
Claim 7
Dependent Claim
21 words
The apparatus according to claim 5 wherein said magnetic tape is rewound by a predetermined tape amount immediately after said recording.
