Abstract: Apparatus is provided for selectively transferring data from one to another of a plurality of display registers. Selector switches are associated with respective ones of the display registers, each selector switch being manually operable so as to be designated either as a source switch or as a destination switch, whereby the data in the display register associated with the source switch is transferred to the display register associated with the destination switch. A central processing unit is responsive to the operation of a first of the selector switches followed by the operation of a second of the selector switches to transfer the data from the display register associated with the first selector switch to the display register associated with the second selector switch.

Abstract: Video editing apparatus for use with video playback and recording devices, such as video tape recorders (VTR's) wherein signals are reproduced from a first record medium and recorded on a second record medium. The apparatus is provided with a console having a plurality of display registers for displaying record medium position data representing respective positions of the first and second media. Register selector switches are associated with respective ones of the display registers, each such switch being operable to select its associated display register. The console also is provided with a plurality of signal selector switches, each being operable to select a particular type of signal (such as a video or audio signal) reproduced from the first medium to be recorded on the second medium when a pre-selected one of the media reaches a position represented by the position data displayed in a selected display register.

Abstract: A cue address generator for generating a cue address representing the position of a respective record medium adapted to be accessed by signal recording/playback apparatus. The cue address generator is particularly adapted to be used in signal editing apparatus of the type wherein signals recorded on a first record medium are transferred to a second record medium when preselected positions of the media are reached. The cue address generator includes a plurality of registers, each operative to store position data representing a relative position of the first or second medium, and a plurality of register selector switches associated with respective ones of the registers, each being selectively operative to select its associated register. Cue selector switches are associated with respective ones of the record media and are selectively operative to initiate a cue address generating operation.

Abstract: For determining the address, in terms of its respective longitudinal time code, of a selected video or other information signal recorded on a tape which has both longitudinal time codes and control pulses or control track signals recorded along its length, when the information signal is selected while the tape is being moved at a speed which is insufficient for the reliable reading of its longitudinal time codes, the tape is accelerated to a speed sufficient for the longitudinal time codes to be reliably read and a subsequently encountered longitudinal time code is read, the reproduced control pulses are counted between the time that an information signal is selected and the time that the subsequently encountered longitudinal time code is read, and a derived address of the selected information signal is determined, in terms of its respective longitudinal time code, as a function of the value of the subsequently encountered longitudinal time code and the count of the reproduced control pulses.

Abstract: An apparatus and a method are provided for detecting discontinuities in a sequence of time code addresses recorded on a tape, such as a video tape, which also has control pulses recorded serially along its length to synchronize the motion of the tape relative to transducer heads which read and write information signals on the tape. The apparatus and method of this invention read the current time code address from the tape, count the control pulses read as the tape moves, establish a known relationship between the current time code address and the count of control pulses, so that the count represents a counted tape address, and compare the current time code address with the counted tape address for producing a non-compare signal in the event of a difference between these two compared values.

Abstract: An error detection arrangement for editing apparatus of the type that is used with playback and recording devices such as VTR's, wherein different signals (e.g. video and audio signals) on a first record medium, such as video tape, are transferred to a second record medium, and wherein the relative positions of the record media are represented by record medium position data.

Abstract: Editing apparatus is provided for controlling the transfer of signals from a playback medium to a recording medium. The apparatus includes a console having a plurality of display registers, including a play IN register for displaying play IN position data representing an edit-in point along the playback medium, a record IN register for displaying record IN position data representing an edit-in point along the recording medium, a play OUT register for displaying play OUT position data representing an edit-out point along the playback medium and a record OUT register for displaying record OUT position data representing an edit-out point along the recording medium. The console also has a plurality of register selector switches, each associated with and adjacent a respective one of the display registers and operable to select the display register associated therewith.
