SDI (Serial Digital Interface) signals can be classified, for example, on the basis of resolution, as SD (Standard Definition) signals that have been used for many years and HD (High Definition) signals having a resolution higher than that of SD signals. As a type of editing system for editing SDI signals, a device for upconverting SD signals into HD signals or downconverting HD signals into SD signals exists. Such a device is disclosed, for example, in Japanese Unexamined Patent Application Publication No. 2003-299039.
