  • Publication number: 20080118222
    Abstract: An apparatus and method for performing reserved-recording of a digital broadcast program are provided. The method includes setting a reservation to record a digital broadcast program, activating a timer to determine a start time of the program when the terminal is turned off, turning on the terminal to record the program when the start time of the program is reached stopping the recording at an end time of the program and turning off the terminal. Regardless of whether the terminal is turned on or off, the reserved program can be recorded during a time period between the start time and end time of the program. The terminal is turned on to record the program when the start time is reached and turned off at the end time, thereby reducing battery consumption.
