摘要:
In an information signal editing device, when a user specifies a desired reproduction section or reproduction start position, a management information file recorded in a memory is rewritten into a second management information file which is created on the basis of the specified information, and a second information file is set on the basis of the second management information file. The information signal editing device constructed as described performs arbitrary virtual editing when a DVD-RAM disk is non-rewritable, whereby the user can obtain a desired reproduction signal.
