Video data inputted from an input terminal 32 is equally divided and recorded on disk drives 18a to 18c, respectively. The video data recorded on the disk drives 18a to 18c is sent out to a data bus 30 at a predetermined timing in accordance with a transfer control command from a data transfer controller 22, and image-processed by a switcher/digital multi-effector 13. Plural channels of video data are laid out in plural time slots formed by dividing a transmission unit having a length equal to a period forming one horizontal line prescribed by a predetermined analog video signal standard, and each channel of video data at least for one frame is transmitted with the transmission unit having a number of lines corresponding to one frame of the analog video signal standard. Thus, a digital data transmission method which enables high-speed synchronous transfer of video data and a data editing device which enables linear editing and non-linear editing may be provided. <IMAGE> |
