Abstract

An EPLmaker (10) is composed mainly of editing terminals (15), (16) and (17) each reading and decoding each of highly compressed sub materials to produce a material data and make an EPL while displaying, on a monitor, a video based on the material data. The EPL includes identification information for identification of a material used in editing and a format declare state for defining a format of at least a certain material. The EPLs made by the editing terminals (15), (16) and (17) are stored into an EPL storage unit (18). The EPLs stored in the EPL storage unit (18) are read by an edit controller (20). The edit controller (20) makes an edit control signal based on the EPLs, and supplies the signal to a content maker (30). Thus, an editing can be executed with having not to pool the materials once on hand and with labors and costs.
