A reception apparatus records a content distributed from a content distribution
apparatus on a hard disk. Following an instruction from a viewer, the reception
apparatus reproduces the content. The reception apparatus transmits management
information including identification information about the content recorded on
the hard disk to a management apparatus. The management apparatus stores the information
in a management information storage. When the hard disk of the reception apparatus
fails, a replacement hard disk is attached to the management apparatus. The management
apparatus retrieves, based on the stored management information, the same content
as the content recorded on the hard disk of the reception apparatus from a content
distribution apparatus, etc., and records the retrieved content on the replacement
hard disk. The hard disk of the reception apparatus is then replaced with the replacement
hard disk with the content recorded thereon.
