  • Patent number: 8073312
    Abstract: A recording condition and a dubbing condition of a desired program that is to be broadcast are designated by using a remote controller. These conditions are stored in the information storage unit. In accordance with the recording condition, a controller permits a tuner to receive a program for which unattended recording is designated, and to record the program on an HDD. When a DVD is set in a dubbing unit and the dubbing operation is instructed by using the remote controller, a recorded program for which a dubbing condition stored in the information storage unit is applied can be dubbed. Then, the information for this program is displayed on a monitor so as to confirm the program and the dubbing condition, and to examine or correct CM skip if the CM skip is included in the dubbing condition. Thereafter, the dubbing operation is performed.
