<p>A reception apparatus (11) records a content distributed from a content distribution apparatus (1) on a hard disk (81). Following an instruction from a viewer, the reception apparatus (11) reproduces the content. The reception apparatus (11) transmits management information including identification information about the content recorded on the hard disk (81) to a management apparatus (21). The management apparatus (21) stores the information in a management information storage (50). When the hard disk (81) fails, a replacement hard disk (82) is attached to the management apparatus (21). The management apparatus (21) retrieves, based on the stored management information, the same content as the content recorded on the hard disk (81) from a content distribution apparatus (1), etc., and records the retrieved content on the replacement hard disk (82). The hard disk (81) is then replaced with the hard disk (82) with the content recorded thereon.</p> |
