摘要

An information processing method of an information processing system including a client device functioning as a client and a server device functioning as a server which are capable of communication via a network, includes the steps of: at the server device, managing format identification information provided so as to be unique for each content data within the range of each data format, corresponding to the contents of each content; at the client device, causing execution of communication via network, for specifying a content, as to the server device; at the server device, transmitting, to the client device, format identification information correlated with a specified content in response to specification of a content via network from the client device; and at the client device, managing the received and obtained format identification information as corresponding to the specified content.

主权项

1. At least one non-transitory computer-readable storage medium having encoded thereon executable instructions that cause a first computing device operated by a user to carry out a method comprising:
storing, on the first computing device operated by the user, information on a plurality of pieces of content data that the user has permission to reproduce, each piece of content data comprising audio and/or video content, the information identifying a first content data that is stored in a first data format on a second computing device operated by the user; controlling transmission, from the first computing device to a media distribution service comprising at least one third computing device, of a request for the first content data and a demonstration that the user has permission to reproduce the first content data, the demonstration that the user has permission to reproduce the first content data comprising an identifier for the first content data that identifies the first content data in a manner that is generic to a data format of the first content data; and controlling receipt, at the first computing device from the media distribution service in response to the transmitting of the request and the demonstration that the user has permission to reproduce the first content data, of the first content data in a second data format different from the first data format.
