<p>Video data inputted from an input terminal (32) are equally divided and recorded onto disk drives (18a-18c), respectively. The video data recorded on the disk drives (18a-18c) are sent to a data bus (30) at a predetermined timing in accordance with a transfer control command from a data transfer controller (22), and are processed by a switcher/digital multi-effector (12). In this case, plural channels of video data are laid out in each time slot which is formed by plurally dividing a transmission unit having a length equal to a period forming one horizontal line prescribed by a predetermined analog video signal standard, and at least one frame of each channel of video data is transmitted by a transmission unit having the number of lines corresponding to one frame of the analog video signal standard. Thus, a digital data transmission method which enables high-speed synchronous transmission of video data, and a data editing device which enables linear editing and non-linear editing may be provided.</p> |
