Abstract
Abstract A first set of digital signals is generated in response to information received from a magnetic tape. The first set of digital signals is stored. A second set of digital signals is generated in response to the first set of stored signals and information received from a punched tape. The second set of digital signals is stored. One or more external devices or peripheral control equipment connected to a plurality of external devices is controlled in response to the second set of stored signals. The second set of stored signals is transmitted in a form for storage on the magnetic tape or the punched tape.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
93 words
A method of controlling one or more audio-visual devices in response to stored information in parallel bit format on a punched tape or in serial bit format on a magnetic tape, comprising: selectively detecting either said information stored in serial bit format on said magnetic tape or in parallel bit format on said punched tape and generating a set of digital signals in parallel bit format in response thereto; temporarily storing said set of digital signals; and controlling said one or more audio-visual devices in response to said set of temporarily stored signals.
Claim 2
Independent Claim
93 words
A method of controlling one or more audio-visual devices in response to stored information in parallel bit format on a punched tape or in serial bit format on a magnetic tape, comprising: selectively detecting either said information stored in serial bit format on said magnetic tape or in parallel bit format on said punched tape and generating a set of digital signals in parallel bit format in response thereto; temporarily storing said set of digital signals; and controlling said one or more audio-visual devices in response to said set of temporarily stored signals.
Claim 3
Dependent Claim
29 words
The method according to claim 1, including converting said set of temporarily stored digital signals from parallel bit format into serial bit format for storage on said magnetic tape.
Claim 4
Dependent Claim
192 words
Apparatus for controlling one or more audio-visual devices in response to stored information in parallel bit format on a punched tape or in serial bit format on a magnetic tape, comprising: first means for detecting said information stored in serial bit format on said magnetic tape and for generating a first set of digital signals in parallel bit format in response thereto; second means for detecting said information stored on said punched tape in parallel bit format and for generating a second set of digital signals in parallel bit format in response thereto; selectively actuatable means operatively connected to said first and second means for cuasing either said first means to detect said magnetic tape information and generate said first set of digital signals or said second means to detect said punched tape information and generate said second set of digital signals; third means operatively connected to said first and second means for temporarily storing said first or second sets of digital signals; and fourth means operatively connected to said third means for controlling said one or more audio-visual devices in response to said set of signals stored in said third means.
Claim 5
Dependent Claim
192 words
Apparatus for controlling one or more audio-visual devices in response to stored information in parallel bit format on a punched tape or in serial bit format on a magnetic tape, comprising: first means for detecting said information stored in serial bit format on said magnetic tape and for generating a first set of digital signals in parallel bit format in response thereto; second means for detecting said information stored on said punched tape in parallel bit format and for generating a second set of digital signals in parallel bit format in response thereto; selectively actuatable means operatively connected to said first and second means for cuasing either said first means to detect said magnetic tape information and generate said first set of digital signals or said second means to detect said punched tape information and generate said second set of digital signals; third means operatively connected to said first and second means for temporarily storing said first or second sets of digital signals; and fourth means operatively connected to said third means for controlling said one or more audio-visual devices in response to said set of signals stored in said third means.
Claim 6
Dependent Claim
35 words
Apparatus according to claim 3, including fifth means for converting said digital signals stored in said third means from parallel bit format into serial bit format in a form for storage on said magnetic tape.
Claim 7
Dependent Claim
15 words
Apparatus according to claim 4 including means for automatically starting and stopping said magnetic tape.
Claim 8
Dependent Claim
39 words
Apparatus according to claim 5 including means for preventing said fifth means from converting said digital signals stored in said third means from parallel bit format to serial bit format until said magnetic tape reaches a stable operating speed.
Claim 9
Dependent Claim
17 words
Apparatus according to claim 4 including means for modulating said converted digital signals in a FSK code.
Claim 10
Dependent Claim
18 words
Apparatus according to claim 3 including means for checking the parity of said first set of digital signals.
