Abstract
Abstract A videotape controller which, during a stunt learn mode activated by closing any one of a plurality of tape speed control switches, memorizes the tape speed switch settings at uniform intervals of time and then replays those tape speed control settings during an auto stunt mode. The current capacity of the memory storage during either mode is visually displayed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
97 words
An improved control system for a tape recorder, the control system being of the type having a plurality of tape speed control switches for setting the tape speed of the videotape recorder, and wherein the improvement comprises memory means and controller means for selectively sampling the electrical conditions of said switches at predetermined, timed intervals and storing the results in the memory means during a first mode, and thereafter, during a second mode, reading out the entire contents of the memory to produce a tape speed control signal corresponding to the switch settings when they were sampled.
Claim 2
Dependent Claim
97 words
An improved control system for a tape recorder, the control system being of the type having a plurality of tape speed control switches for setting the tape speed of the videotape recorder, and wherein the improvement comprises memory means and controller means for selectively sampling the electrical conditions of said switches at predetermined, timed intervals and storing the results in the memory means during a first mode, and thereafter, during a second mode, reading out the entire contents of the memory to produce a tape speed control signal corresponding to the switch settings when they were sampled.
Claim 3
Dependent Claim
35 words
A control system for a tape recorder as recited in claim 1 wherein the controller means is initially activated into its first mode by the actuation of any one of the tape speed control switches.
Claim 4
Dependent Claim
39 words
A control system for a tape recorder as recited in claim 1 further comprising a display having a series of energizable elements with each of said display elements representing a different group of predetermined locations in said memory means.
Claim 5
Dependent Claim
49 words
A control system for a tape recorder as recited in claim 3 wherein said controller means, during the first mode, energizes each of said display elements as the first one of the corresponding memory location in the group corresponding to said display element is filled with the sampling results.
Claim 6
Dependent Claim
45 words
A control system for a tape recorder as recited in claims 3 or 4 wherein said controller means, during the second mode, energizes each of said display elements as the first one of each of the memory locations in the corresponding group is read out.
Claim 7
Dependent Claim
41 words
A control system for a tape recorder as recited in claim 2 further comprising stunt learn switch means for selectively enabling the controller means to operate in its first mode when any one of the tape speed control switches is actuated.
Claim 8
Dependent Claim
31 words
A control system for a tape recorder as recited in claim 2 further comprising auto stunt switch means for selectively causing the controller means to begin operating in its second mode.
Claim 9
Dependent Claim
32 words
A control system for a tape recorder as recited in claim 3 wherein the display, when the controller means is not operating in either its first or second modes, displays cue positions.
Claim 10
Dependent Claim
85 words
A control system for a tape recorder as recited in claims 2 or 6, further comprising an energizable stunt learn indicator and wherein the controller means, after beginning the first mode, determines whether the tape is then stopped in the VTR, and, if it is, terminates the first mode, and if the tape is not stopped, flashes the stunt learn indicator until one of the tape speed control switches is actuated, at which time the controller causes the stunt learn indicator to be continuously energized.
Claim 11
Dependent Claim
47 words
A control system for a tape recorder as recited in claim 1 wherein the controller means, after beginning the second mode, first causes the tape to move until a predetermined cue point is reached, after which the controller means reads out the contents of the memory means.
Claim 12
Independent Claim
83 words
A method of preprogramming a sequence of tape speed changes for a magnetic tape recorder of the type having a plurality of different tape speed control switches comprising the steps of manually activating a series of such tape speed control switches while simultaneously sampling and storing the electrical condition of such switches at uniform intervals of time and thereafter automatically operating the tape recorder at a series of speeds corresponding to the sampled and stored electrical conditions of the tape speed control switches.
Claim 13
Independent Claim
83 words
