Abstract
Abstract A time code generator having a time code generating circuit for generating a first time code signal in response to a vertical synchronizing signal, a memory for storing a second time code signal reproduced from a VTR, a circuit for comparing the first time code signal with the second time code signal to produce an inconformity signal, a counter for counting the inconformity signal and a circuit for loading the second time code signal to the time code generating circuit according to an output of the counter.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
A time code signal generator for a tape recorder, the time code signal generator comprising: a time code generator (20) for generating a first time code signal incrementally in response to a synchronizing signal; a time code reader (12) for reading a second time code signal reproduced from a tape recorder; a comparator (15) for comparing said first time code signal with said second time code signal to produce an output signal representing an inconformity between said first and second time code signals; a counter (17) for counting said output signal of comparator (15); and means (24) for changing the output of said time code generator to said second time code signal in response to an output of said counter (17).
Claim 2
Dependent Claim
121 words
A time code signal generator for a tape recorder, the time code signal generator comprising: a time code generator (20) for generating a first time code signal incrementally in response to a synchronizing signal; a time code reader (12) for reading a second time code signal reproduced from a tape recorder; a comparator (15) for comparing said first time code signal with said second time code signal to produce an output signal representing an inconformity between said first and second time code signals; a counter (17) for counting said output signal of comparator (15); and means (24) for changing the output of said time code generator to said second time code signal in response to an output of said counter (17).
Claim 3
Dependent Claim
33 words
A time code signal generator according to claim 1 wherein said time code generator (20) comprises a register (21a) and an arithmetic circuit (21b) for calculating an output from said register (21a) sequentially.
Claim 4
Dependent Claim
28 words
A time code signal generator according to claim 1 further comprising a memory (14) for storing said first time code signal and said second time code signal respectively.
Claim 5
Dependent Claim
20 words
A time code generator according to claim 1 wherein said first time code signal is incremented in every frame period.
