Abstract

Abstract An editing apparatus having playback means (2A,...2D) for reproducing video signals from recording media and a recording means (4) for recording the reproduced video signals on a recording medium, further comprising: a signal processing means (18, 38, 46, 52) for adding special effect to the input video signal and outputting the processed signal; a switcher (12) having a plurality of input terminals and a plurality of output terminals, and delivering the input video signal selectively to a desired output terminal; a first parallel-to-serial converting means (8A,...8D) for executing parallel-to-serial conversion of the digital video signal obtained from the playback means (2A,...2D) and supplying the converted signal to the first input terminal of the switcher (12); a first serial-to-parallel converting means (14A,...14D) for executing serial-to-parallel conversion of the digital video signal obtained from the first output terminal of the switcher (12) and supplying the converted signal to the signal processing means; a second parallel-to-serial converting means (20) for executing parallel-to-serial conversion of the digital video signal obtained from the signal processing means and supplying the converted signal to the second input terminal of the switcher (12); and a second serial-to-parallel converting means (16) for executing serial-to-parallel conversion of the digital video signal obtained from the second output terminal of the switcher (12) and supplying the converted signal to the recording means. Due to such constitution, the entire apparatus can be dimensionally reduced to realize a compact structure.

Claims Analysis

Total Claims: 5

Claim 1

Independent Claim 229 words

An editing apparatus having playback means (2A,...2D) for reproducing video signals from recording media and a recording means (4) for recording the reproduced signals on a recording medium, said apparatus comprising: a) a signal processing means (18, 38, 46, 52) for adding special effect to an input video signal and outputting the processed signal; b) a switcher (12) having a plurality of input terminals and a plurality of output terminals, and delivering the input video signal selectively to a desired output terminal; c) a first parallel-to-serial converting means (8A,...8D) for executing parallel-to-serial conversion of the digital video signal obtained from said playback means (2A,...2D) and supplying the converted signal to the first input terminal of said switcher (12); d) a first serial-to-parallel converting means (14A,...14D) for executing serial-to-parallel conversion of the digital video signal obtained from the first output terminal of said switcher (12) and supplying the converted signal to said signal processing means (38, 46, 52); e) a second parallel-to-serial converting means (20) for executing parallel-to-serial conversion of the digital video signal obtained from said signal processing means and supplying the converted signal to the second input terminal of said switcher (12); and f) a second serial-to-parallel converting means (16) for executing serial-to-parallel conversion of the digital video signal obtained from the second input terminal of said switcher (12) and supplying the converted signal to said recording medium.

Claim 2

Dependent Claim 26 words

An editing apparatus according to claim 1, wherein each of said playback means (2A,...2D) and said recording means (4) consists of a digital video tape recorder.

Claim 3

Dependent Claim 108 words

An editing apparatus according to claim 1 or 2, wherein said switcher (12) comprises: a selecting means (38, 41) for selectively outputting the signal supplied from said first parallel-to-serial converting means and/or the signal supplied from said second parallel-to-serial converting means; a third serial-to-parallel converting means (42A,...42D, 44A,...44D) for executing serial-to-parallel conversion of the digital video signal obtained from said selecting means (38, 41); a mix effector means (46, 48) for level-processing the digital video signal obtained from said third serial-to-parallel converting means; and a third parallel-to-serial converting means for executing parallel-to-serial conversion of the processed signal obtained from said mix effector means and outputting the converted signal

Claim 4

Dependent Claim 43 words

An editing apparatus according to anyone of claims 1 to 3, further comprising a control means (6, 38, 54) for controlling said playback means (2A,...2D), said recording means (4), said signal processing means and said switcher (12) in accordance with the editing data.

Claim 5

Dependent Claim 21 words

An editing apparatus according to anyone of claims 1 to 4, wherein said editing data are reproduced from floppy disks (56).
