ABSTRACT:
In a digital recording device, image data recorded in a recording portion has its resolution decreased to be recorded in the recording portion when it is determined that the digital recording device is not being used. In other words, when it is determined that a power switch is turned off, a system portion allows an MPEG decoder to convert a bit stream of a program data at high definition recorded in a hard disk drive to image data at low resolution and allows an MPEG encoder to convert the converted image data at low resolution to a bit stream to be stored in the hard disk drive.
