Abstract
Abstract A single unit remote controller adapted to control predetermined functions of first and second video tape recorders (VTR) connected each other for performing a signal transfer between the first and second VTRs is disclosed. The first VTR is preconditioned to be responsive exclusively to a first remote control code signal (code A) and the second VTR is preconditioned to be responsive exclusively to a second remote control code signal (code B) to perform the predetermined functions. The single unit remote controller comprises function keys corresponding to the predetermined functions of the first and second VTRs for commanding remotely the predetermined functions, code generation unit for generating the code A and code B combined in sequence with an interruption of a predetermined time period therebetween in response to a depression of a specific key of the function keys, and, transmission unit for transmitting the code A and code B generated by the code generation means to the first and second VTRs.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A single unit remote controller adapted to control predetermined functions of first and second video tape recorders (VTR) connected each other for performing a signal transfer between the first and second VTRs, said first VTR being preconditioned to be responsive exclusively to a first remote control code signal (code A) and said second VTR being preconditioned to be responsive exclusively to a second remote control code signal (code B) to perform said predetermined functions, said single unit remote controller comprising: function keys corresponding to said predetermined functions of the first and second VTRs for commanding remotely said predetermined functions, code generation means for generating said code A and code B combined in sequence with an interruption of a predetermined time period therebetween in response to a depression of a specific key of the function keys, and, transmission means for transmitting said code A and code B generated by said code generation means to said first and second VTRs.
Claim 2
Dependent Claim
158 words
A single unit remote controller adapted to control predetermined functions of first and second video tape recorders (VTR) connected each other for performing a signal transfer between the first and second VTRs, said first VTR being preconditioned to be responsive exclusively to a first remote control code signal (code A) and said second VTR being preconditioned to be responsive exclusively to a second remote control code signal (code B) to perform said predetermined functions, said single unit remote controller comprising: function keys corresponding to said predetermined functions of the first and second VTRs for commanding remotely said predetermined functions, code generation means for generating said code A and code B combined in sequence with an interruption of a predetermined time period therebetween in response to a depression of a specific key of the function keys, and, transmission means for transmitting said code A and code B generated by said code generation means to said first and second VTRs.
Claim 3
Dependent Claim
31 words
A single unit remote controller as claimed in claim 1 wherein said specific key is an editing start key for commanding said first and second VTRs to perform said signal transfer.
Claim 4
Dependent Claim
73 words
A single unit remote controller as claimed in claim 1 further comprising: mode changeover means for disabling said code generation means generating said code A and code B combined in sequence with the interruption therebetween, and enabling said code generation means generating only one of the code A and the code B to control corresponding one of the first and second VTRs at a time upon depression of one of the function keys.
Claim 5
Dependent Claim
50 words
A single unit remote controller as claimed in claim 3, wherein said mode changeover means comprising a first key for selecting one of the code A and the code B to be transmitted, and a second key for generating only one code selected by a depression of the first key.
Claim 6
Dependent Claim
61 words
A single unit remote controller as claimed in claim 2, wherein each of the code A and the code B is headed by a system code followed by a data code, said system code causing a corresponding VTR of the first and second VTRs responding to said data code when said first and second VTRs receive said codes A and B.
