摘要：
A server apparatus (1) includes a deletion information decision section (104) and a management information update section (105). The deletion information decision section (104) decides a file from among files of an AV content already stored in a storage section (202) of a receiving apparatus (2), the file to be decided being so deleted as to be prevented from being used in the receiving apparatus (2) when files constituting an AV content that is to be newly transmitted is stored in the storage section (202). The management information update section (105) transmits, to the receiving apparatus (2), management information including deletion information for specifying the file thus decided. The receiving apparatus (2) includes a deletion section (205) for deleting, from the storage section (202), the file specified by the deletion information of the management information received from the server apparatus (1).
