Abstract: The A/V server manages data to be edited in the form of edit data pages (will be referred to as “page” herebelow) and program as a collection of the pages. The page data include recorder- and player-side device names, file names and edition points per page. The data in all the pages are collected as a program. A page number to identify each page is represented by a sequence of information assigned in the produced order in each page. The A/V server changes only the page number in the temporal order of the IN points in the destination data and produces a program in which the page data are re-arranged. Also when re-accessing near the same material data recorded in a VTR, the A/V server accesses data recorded in the HDD, not in the VTR.
