Abstract

Abstract Video and other information is provided on a first recording medium recorded at a standard speed and in a standard format in a series of tracks slanted relative to a direction of movement of the first recording medium. That information is reproduced from that series of tracks on the first recording medium in the form of electric signals seriatim at increased speed on the order of a multiple (n) of said standard speed, and such reproduced information is simultaneously rerecorded from said electric signals seriatim in a standard format with series of tracks on several second recording media at said increased speed, for replay of said rerecorded information by several end users at different times from said several recording media at standard speed.

A system for duplicating, for end users, information having been provided on a first recording medium (2l) recorded at a standard speed and in a standard format in a series of tracks (22) slanted relative to a direction of movement (23) of the first recording medium, characterised by a combination of a playback apparatus (3l) for reproducing said information from said series of tracks (22) on the first recording medium (2l) in the form of electric signals seriatim at increased speed on the order of a multiple (n) of said standard speed, and recording apparatus (96, 97, 98) connected to said playback appratus for simultaneously rerecording said reproduced information from said electric signals seriatim in a standard format with series of tracks (l02) on several second recording media (l03, l04, l05) at said increased speed, for replay of said rerecorded information by several end users at different times from said several recording media at standard speed (Fig. 3).
Claim 2
Independent Claim 158 words
A system for duplicating, for end users, information having been provided on a first recording medium (2l) recorded at a standard speed and in a standard format in a series of tracks (22) slanted relative to a direction of movement (23) of the first recording medium, characterised by a combination of a playback apparatus (3l) for reproducing said information from said series of tracks (22) on the first recording medium (2l) in the form of electric signals seriatim at increased speed on the order of a multiple (n) of said standard speed, and recording apparatus (96, 97, 98) connected to said playback appratus for simultaneously rerecording said reproduced information from said electric signals seriatim in a standard format with series of tracks (l02) on several second recording media (l03, l04, l05) at said increased speed, for replay of said rerecorded information by several end users at different times from said several recording media at standard speed (Fig. 3).
Claim 3
Independent Claim 106 words
A system according to claim l, for information provided on said first recording medium (2l) pursuant to said standard speed and in said standard format with the aid of first synchronization signals having standard synchronization frequencies (f), characterised by an oscillator (7l) for providing second synchronization signals having frequencies (nf) increased by said multiple (n) relative to said standard synchronization frequencies (f), and signal processing means (74) connected to said playback apparatus (3l) for processing said electric signals with said second synchronization signals having said increased frequencies (nf), said recording appratus (96, 97, 98) effecting said rerecording of said reproduced information from said processed electric signals.
Claim 4
Dependent Claim 55 words
A system according to claim 2, characterised by means (72) connected to said oscillator (7l) for deriving from said second synchronization signals having said increased frequencies (nf) third synchronization signals having said standard frequencies (f), and means (53, 59) for synchronizing said playback and rerecording apparatus (3l, 96, 97, 98) with said third synchronization signals.
Claim 5
Dependent Claim 46 words
A system according to claim 3, wherein the synchronising means comprising servo means for synchronising the playback and rerecording apparatus (3l, 96, 97, 98), and means connected to the servo means for effecting synchronization of the reproduction and rerecording in response to said third synchronization signals.
Claim 6
Independent Claim 182 words
A system according to any one of the preceding claims, wherein said playback apparatus (3l) includes reproducing devices (4l, 42) for reproducing said information in the form of said electric signals from said first recording medium (2l) in the form of a first tape (l9) having said information stored thereon, and means (48, 5l, 58) for moving said first tape and moving said reproducing devices (4l, 42) relative to said moving first tape, and said recording apparatus (96, 97, 98) include recording devices (l2l, l22) for rerecording said reproduced information from said electric signals onto said second recording media (l03, l04, l05) in the form of second tapes for receiving said information, and means (l4l, l46, l47) for moving said second tapes and moving said recording devices (l2l, l22) relative to said moving second tapes. signal processing means (74) connected to said reproducing devices (4l, 42) for processing electric signals containing information reproduced by said moving reproducing devices with said second synchronization signals, said moving recording devices (l2l, l22) recording said processed electric signals on said moving second tapes (l03, l04, l05).
Claim 7
Independent Claim 145 words
A method of duplicating, for end users, information having been provided on a first recording medium (2l) recorded at a standard speed and in a standard format in a series of tracks (22) slanted relative to a direction of movement (23) of the first recording medium, characterised by the combination of the steps of reproducing said information from said series of tracks (22) on the first recording medium (2l) in the form of electric signals seriatim at increased speed on the order of a multiple (n) of said standard speed, and simultaneously rerecording said reproduced information from said electric signals seriatim in a standard format with series of tracks (l02) on several second recording media (l03, l04, l05) at said increased speed, for replay of said rerecorded information by several end users at different times from said several recording media at standard speed (Fig. 3).
Claim 8
Independent Claim 145 words
A method of duplicating, for end users, information having been provided on a first recording medium (2l) recorded at a standard speed and in a standard format in a series of tracks (22) slanted relative to a direction of movement (23) of the first recording medium, characterised by the combination of the steps of reproducing said information from said series of tracks (22) on the first recording medium (2l) in the form of electric signals seriatim at increased speed on the order of a multiple (n) of said standard speed, and simultaneously rerecording said reproduced information from said electric signals seriatim in a standard format with series of tracks (l02) on several second recording media (l03, l04, l05) at said increased speed, for replay of said rerecorded information by several end users at different times from said several recording media at standard speed (Fig. 3).
