Abstract
Abstract The present invention provides a useful video editing system capable of reading shot directly from an original source and preparing a master tape to which vide effects such as wipes are applied and a method thereof. The video editing system comprises a video storage device for storing video data which is composed of an array of a number of frames and which can be concurrently reproduced through two channels or more, a shot information storage device for storing shot information which designates the storage location of each shot to be reproduced in the video storage device, a shot link information output device for releasing shot link information as output which specifies a link order and a link method for the shots to be reproduced, a channel allocation determining device for determining, in accordance with the shot link information, to which of the channels each shot to be reproduced should be allocated and releasing it as channel allocation information, a shot reproduction control device for accessing the video storage device to read the shots to be reproduced from the determined channels in the determined order in accordance with the shot information, the shot link information and the channel allocation information, and an effects generator device for linking the plurality of shots of the plurality of channels, which are sent from the shot reproduction control device, in the determined link method and creating video effects to be applied to the linked shots.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
197 words
A video editing system comprising: video storage means for storing video data which is composed of an array of a number of frames and which can be concurrently reproduced through two channels or more; shot information storage means for storing shot information which designates the storage location of each shot to be reproduced in the video storage means; shot link information output means for releasing shot link information as output which specifies a link order and a link method for the shots to be reproduced; channel allocation determining means fordetermining, in accordance with the shot link information, to which of the channels each shot to be reproduced should be allocated and releasing it as channel allocation information; shot reproduction control means for accessing the video storage means to read the shots to be reproduced from the determined channels in the determined order in accordance with the shot information, the shot link information and the channel allocation information; and effects generator means for linking the plurality of shots of the plurality of channels, which are sent from the shot reproduction control means, in the determined link method and creating video effects to be applied to the linked shots.
Claim 2
Dependent Claim
197 words
A video editing system comprising: video storage means for storing video data which is composed of an array of a number of frames and which can be concurrently reproduced through two channels or more; shot information storage means for storing shot information which designates the storage location of each shot to be reproduced in the video storage means; shot link information output means for releasing shot link information as output which specifies a link order and a link method for the shots to be reproduced; channel allocation determining means fordetermining, in accordance with the shot link information, to which of the channels each shot to be reproduced should be allocated and releasing it as channel allocation information; shot reproduction control means for accessing the video storage means to read the shots to be reproduced from the determined channels in the determined order in accordance with the shot information, the shot link information and the channel allocation information; and effects generator means for linking the plurality of shots of the plurality of channels, which are sent from the shot reproduction control means, in the determined link method and creating video effects to be applied to the linked shots.
Claim 3
Dependent Claim
53 words
A video editing system according to Claim 1, wherein the video storage means includes a high-speed disc medium having the ability of transferring video data at high speeds and FIFOs for storing the video data transferred from the high-speed disc medium, the number of FIFOs being the same as the number of channels.
Claim 4
Dependent Claim
72 words
Avideo editing system according to Claim 2, wherein the channel allocation determining means comprises a first allocation unit for allocating a first shot in the shot link information to a first channel; and a second allocation unit for allocating a following shot to a channel different from a channel to which a preceding shot has been allocated, when the preceding and following shots are overlapped in terms of time at their joint.
Claim 5
Dependent Claim
133 words
A video editing system according to Claim 3, wherein the shot reproduction control means comprises: a first detection unit for detecting a shot to be reproduced from the shot link information; a second detection unit for detecting the storage location of the detected shot in the high-speed disc medium from the shot information; a transfer control unit for transferring the shot from the location in the high-speed disc medium detected by the second detection unit to one of the FIFOs for a channel to which the shot is allocated in the channel allocation information; and an output unit for reading the shot to be reproduced from the FIFO for the channel to which the shot has been allocated, in synchronization with the cycle of the frames, to release to the effects generator means.
Claim 6
Dependent Claim
58 words
A video editing system according to Claim 4, further comprising: a first input unit for entering data to be stored as the shot information in the shot information storage means; and a second input unit for entering data for specifying a link order and a link method for the shots to be reproduced, as the shot link information.
Claim 7
Dependent Claim
38 words
A video editing system according to Claim 1, wherein the video storage means includes VTRs, the number of which is the same as the number of channels and each VTR has a tape having the same video data.
Claim 8
Dependent Claim
72 words
Avideo editing system according to Claim 6, wherein the channel allocation determining means comprises a first allocation unit for allocating a first shot in the shot link information to a first channel; and a second allocation unit for allocating a following shot to a channel different from a channel to which a preceding shot has been allocated, when the preceding and following shots are overlapped in terms of time at their joint.
Claim 9
Dependent Claim
