Abstract
Abstract In a time information generator (25, 26, 27) for generating time information with respect to an arbitrary frame of video information varying with time on the basis of time information delivered at predetermined time intervals from video information forming device (10) for forming video information as mentioned above, there is employed a scheme to discriminate between operational modes of the video information forming device (10) to form, by an interpolative operation, time information in said arbitrary frame of video information from time information delivered from the video information forming device every n ( n = 2, 3, 4, ...) frames of video information on the basis of the result indicative of the discriminated operational mode.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
A time information generator for generating time information with respect to an arbitrary frame of video information varying with time on the basis of time information delivered, at predetermined intervals, from video information forming means for forming said video information, comprising: a) discrimination means for discriminating between operational modes of said video information forming means; b) time information sense means for receiving time information from said video information forming means n (n being a positive integer greater than 1) frames of said video information; and c) interpolative operation means adapted to be supplied with an output signal from said discrimination means and an output signal from said time information sense means to perform an interpolative operation corresponding to said discriminated operational mode to generate time information with respect to said arbitrary frame of said video information.
Claim 2
Dependent Claim
136 words
A time information generator for generating time information with respect to an arbitrary frame of video information varying with time on the basis of time information delivered, at predetermined intervals, from video information forming means for forming said video information, comprising: a) discrimination means for discriminating between operational modes of said video information forming means; b) time information sense means for receiving time information from said video information forming means n (n being a positive integer greater than 1) frames of said video information; and c) interpolative operation means adapted to be supplied with an output signal from said discrimination means and an output signal from said time information sense means to perform an interpolative operation corresponding to said discriminated operational mode to generate time information with respect to said arbitrary frame of said video information.
Claim 3
Dependent Claim
134 words
A time information generator for generating time information with respect to an arbitrary frame of video information on the basis of time information delivered at predetermined time intervals from a playback device for playing back video information from a magnetic tape, comprising: a) discrimination means for discriminating between operational modes of said playback device; b) time information sense means for receiving time information from said playback device every n (n being a positive integer greater than 1) frames of said video information; and c) interpolative operation means adapted to be supplied with an output signal from said discrimination means and an output signal from said time information sense means to perform an interpolative operation corresponding to said discriminated operational mode to generate time information with respect to said arbitrary frame of said video information.
Claim 4
Dependent Claim
134 words
A time information generator for generating time information with respect to an arbitrary frame of video information on the basis of time information delivered at predetermined time intervals from a playback device for playing back video information from a magnetic tape, comprising: a) discrimination means for discriminating between operational modes of said playback device; b) time information sense means for receiving time information from said playback device every n (n being a positive integer greater than 1) frames of said video information; and c) interpolative operation means adapted to be supplied with an output signal from said discrimination means and an output signal from said time information sense means to perform an interpolative operation corresponding to said discriminated operational mode to generate time information with respect to said arbitrary frame of said video information.
Claim 5
Dependent Claim
30 words
A time information generator as set forth in claim 2, wherein said discrimination means is operative to discriminate between STOP, PLAY, JOG and VARIABLE SPEED modes of said playback device.
Claim 6
Dependent Claim
50 words
A time information generator as set forth in claim 2 or 3, wherein said interpolative operation means is responsive to an output signal from said interpolative operation means to add a predetermined value to time information delivered from said playback device to thereby generate time information in said arbitrary frame.
Claim 7
Dependent Claim
133 words
A time information generator as set forth in claim 4, wherein when the operational mode of said playback device is STOP mode, said interpolative operation means outputs, as current time information, time information determined by the last interpolative operation; when the operational mode of said playback device is PLAY mode, said interpolative operation means outputs, as current time information, a value obtained by adding a time corresponding to one frame of said video information to time information determined by the last interpolative operation; and when the operational mode of said playback device is JOG mode and VARIABLE SPEED mode, said interpolative operation means outputs, as current time information, a value obtained by adding a time corresponding to a running speed of said magnetic tape to time information determined by the last interpolative operation.
Claim 8
Dependent Claim
23 words
A time information generator as set forth in claim 2, 3, 4 or 5 wherein said time information is a time code signal.
Claim 9
Dependent Claim
139 words
A time information generator for generating time information with respect to an arbitrary frame of video information indicative of an input image on the basis of time information delivered, at predetermined time intervals, from a digital video effector for transforming the input image to form an output image, comprising: a) discrimination means for discriminating between operational modes of said digital video effector; b) time information sense means for receiving time information from said digital video effector every n ( n = 2, 3, 4, ...) frames of said video information; and c) interpolative operation means adapted to be supplied with an output signal from said discrimination means and an output from said time information sense means to perform an interpolative operation corresponding to the discriminated operational mode to generate time information in said arbitrary frame of said video information.
Claim 10
Dependent Claim
139 words
A time information generator for generating time information with respect to an arbitrary frame of video information indicative of an input image on the basis of time information delivered, at predetermined time intervals, from a digital video effector for transforming the input image to form an output image, comprising: a) discrimination means for discriminating between operational modes of said digital video effector; b) time information sense means for receiving time information from said digital video effector every n ( n = 2, 3, 4, ...) frames of said video information; and c) interpolative operation means adapted to be supplied with an output signal from said discrimination means and an output from said time information sense means to perform an interpolative operation corresponding to the discriminated operational mode to generate time information in said arbitrary frame of said video information.
