Abstract
A recording and reproducing module records a signal (broadcast program) based on a first compression method to a recording medium, and during a period of time during which recording is not performed, reproduces the signal based on the first compression method, which has been recorded to the recording medium. Then, a transcoding module transcodes the signal based on the first compression method to a signal based on a second compression method. The signal based on the second compression method, whose transcoding has been completed, is recorded to the recording medium; and the signal based on the first compression method is erased from the recording medium. The controller refers to recording history information and sets a schedule including a target broadcast program to be transcoded and a time zone in which the target broadcast program is transcoded.
