BRIEF SUMMARY
DESCRIPTION
1. Technical Field
This invention relates to an edition system. The invention is suitable for, for example, a system for editing a material required to be reported as soon as possible such as sports and news reports.
2. Background Art
This invention has been made in view of the aforementioned point. The invention is intended to provide an edition system which is capable of realizing a real time edition with a smaller system as compared with the prior art.
Considering the above point, in this invention, an edition system comprising: a main recording and reproducing apparatus comprising, input/output means for receiving input video data inputted at a real time, outputting video data obtained from the input video data as first video data at a real time, and outputting video data reproduced from the recording medium as second video data at a real time, and recording and reproducing means for actually performing the recording operation for recording input video data inputted at a real time on the recording medium simultaneously with the reproducing operation for reproducing the video data recorded on said recording medium at a real time; and a computer comprising display means for displaying a graphic display for a user interface which generates a control command relating to the recording and reproducing operation of said main recording and reproducing apparatus, and the first video data and the second video data which are supplied from said main recording and reproducing apparatus at a real time, and event producing means having a first event producing operation for producing a first event from the first video data by operating the user interface displayed on said display means, and a second event producing operation for producing a second event from the second video data by operating the user interface displayed on said display means, said second event producing operation is performed independently of said first event producing operation, is used, thereby, a high-speed real time edition can be realized.
