ABSTRACT:
A DVD recorder system having a sleep state. When a predetermined period of a non-operation state has elapsed, a key controller switches the state of a power source circuit to interrupt voltage supply, thereby causing the system to shift to the sleep state. In this state, when a signal is input from the video input terminal, the key controller controls the power source circuit to turn ON, thereby causing the system to shift to the normal state. After recovery to the normal state, a DVD processor provides instructions to a DVD drive in accordance with recording conditions which are prestored in an EEPROM, and supplies an input video signal to the DVD drive so as to start recording. Also, when a medium is inserted in the DVD drive, the key controller detects an insertion signal to control the power source circuit to turn ON, thereby causing the system to return to the normal state.
