Abstract: Video program information is edited from plural prerecorded source media onto an edited record medium. Each source medium includes video program information of a common scene which may be recorded at a location on the medium relative to a beginning location thereof that differs from the location relative to the beginning location on another source medium on which the same common scene is recorded. Each source medium includes address data representing discrete positions thereon and when the program information of the common scene is played back concurrently from the plural source media, the address data associated with the respective media also are played back. The played program information is monitored, and when a scene location in the common scene is played back substantially simultaneously from plural source media, the address data from each source medium representing the actual position at which the scene location is recorded on that source medium is stored as synchronized address data.

Abstract: A special effect generating system processes first, second, and third video signals supplied respectively from first, second, and third video signal sources to produce an output video signal with special effects. At a plurality of points of time along a first time base, first control data indicative of positions of edges of a first image represented by the first video signal are generated and stored in a first memory. At a plurality of points of time along a second time base, second control data indicative of positions of a boundary between second and third images represented by the second and third video signals are generated and stored in a second memory. The first, second, and third video signals are combined into the output video signal based on the first and second control data stored in the first and second memories.

Abstract: An editing apparatus controls a plurality of video tape recorders so that a slow motion picture, a quick motion picture or a combination of the slow motion picture and the quick motion picture reproduced by the video tape recorder can be edited on a video tape. The editing apparatus includes an input keyboard to input data of a desired tape speed at first and second tape positions, a calculating circuit for calculating a tape speed at any position between said first and second positions on the basis of the input data, and a control circuit for controlling a tape speed of said video tape recorders in response to an output signal of said calculating circuit.

Abstract: Editing data producing apparatus produces first data for editing a cinema film based on second editing data obtained by editing a television video signal reproduced from a record medium on which a cinema signal is recorded in a manner of the television video signal. The video signal is obtained from the cinema signal by an m:n ratio (m and n are both integers) pull-down conversion. An editing video frame address representative of an editing location of the video signal and a reference video frame address representative of the video frame address corresponding to a predetermined cinema frame address of the cinema signal are supplied to a circuit which then produces a relative address between the editing video frame address and the reference video frame address. A circuit is provided for dividing a number representative of the relative address by a number bearing a predetermined relation to m and n, so that a remainder is detected.

Abstract: A time code signal is reproduced from a running tape of an audio tape recorder and is used to search a desired tape stop position. There are provided time code comparing means (13) for comparing same or difference between data of a reproduced time code indicative of the present tape position and a cue point position at which the tape should be stopped (1), mode control means (14) for producing a mode specifying signal on the basis of the compared result of the time code comparing means (13), and timer control means (15) for producing a head drive signal to permit a reproducing head of the audio tape recorder (1) to contact with or leave the tape on the basis of the outputs from the time code comparing means (13) and the mode control means (14).

Abstract: Apparatus for generating bi-phase coded characters formed of a predetermined number of bi-phase signals representing binary bits "1" and "O" having a constant relation between the phases at the beginning and end of each coded character regardless of the number of "1"s and "0"s included in the coded character. A source of binary bits supplies trains of serial bits corresponding to the coded characters, these serial bits being supplied to a bi-phase signal generator which is responsive to each bit for generating a respective bi-phase signal. A binary bit of predetermined sense is supplied in time coincidence with a selected one of the bits in each coded character; and this bit of predetermined sense is selectively inserted into the train of binary bits which is supplied to the bi-phase generator, thereby maintaining the constant relation between the phases at the beginning and end of the bi-phase coded character generated by the bi-phase signal generator.
