To enable editing of recorded information and to enable temporary stop of recording while performing encoding processing.

A recording processing part 16 generates a recording format frame comprising time stamp information, attribute information to which at least a recording temporary stop flag and a recording restart flag can be set, and an information contents part of encoded information being a recording object when recording the encoded information. A reproducing processing part 17 sets a reproducing timer by a time stamp value in the recording format frame to reproduce the encoded information in the recording format frame. When the recording restart flag is set in the recording format frame being the reproducing object, the reproducing processing part 17 sets the reproducing timer by the time stamp value in the recording format frame, where the recording restart flag is set, to continue reproducing from encoded information in the frame.
