A combination system is constructed with a DVD device and a VCR device, and the DVD device has an OSD block. The OSD block of the DVD device produces an OSD, and the VCR device receives an operation command that a user inputs after looking up the OSD. The VCR device transfers the received operation command to the DVD device. The DVD device interprets the transferred operation command, performs a corresponding operation if the operation command is related to the DVD device, and transfers the operation command to the VCR device for a corresponding operation if the operation command is related to the VCR device. Accordingly, a user can conveniently manipulate the DVD device and the VCR device by using a single OSD.
