Abstract

A communications system and method, an information processing apparatus and method, an information management apparatus and method, a recording medium and a program make it possible to efficiently and comfortably make use of contents, which are stored in one server, from a plurality of devices connected via a network. In a case in which the playing of content is stopped, bookmark information including a time stamp representing the stopped position of the content is stored in association with predetermined identification information. The bookmark information is available for various apparatuses transmitting the identification information. When playing the content from a position designated by the information from a predetermined apparatus, the time stamp included in the bookmark information is referred to and the playing of the content from the stopped position is started. The present disclosure is applicable to a personal computer, audio equipment, a PDA, a mobile phone and the like.

Claims

1. An information processing apparatus comprising:

a processor programmed to execute instructions comprising;

requesting, via a network, playing of content from a playing position represented by a time stamp; and

playing said content from said playing position represented by said time stamp in accordance with a response to the requesting of the playing of said content from said playing position represented by said time stamp,

wherein the response is based on a result of judging whether the play of said content from said playing position represented by said time stamp is allowed based on access right information and identification information stored in association with the time stamp, wherein the identification information includes user identification information allotted to each user and user group identification information allotted to each user group, wherein the access right information includes information indicating whether confirmations, by user identification information and user group identification information, of an access right to said playing position of the content represented by said time stamp are necessary,

wherein the judging includes determining whether a confirmation of an access right by user group identification information is necessary (i) in a case where a determination is that user information identification transmitted with the request for the playing of said content from said playing position represented by said time stamp does not match the user identification information stored in association with the time stamp and (ii) in a case where a determination is that a confirmation of an access right by user identification information is not necessary, and

wherein said information processing apparatus is to connect via said network to another information processing apparatus, said playing position represented by said time stamp corresponds to a stopped position whereat a user requested that said content be stopped by use of one of said information processing apparatus and said another information processing apparatus.

2. An information management apparatus comprising:

a processor programmed to execute instructions comprising;

judging whether provision of content from a playing position represented by a time stamp is allowed based on access right information and identification information stored in association with the time stamp, responsive to a request received, over a network, for the playing of said content from said playing position represented by said time stamp, wherein the identification information includes user identification information allotted to each user and user group identification information allotted to each user group, and wherein the access right information includes information indicating whether confirmations, by user identification information and user group identification information, of an access right to said playing position of the content represented by said time stamp are necessary,

wherein the judging includes determining whether a confirmation of an access right by user group identification information is necessary (i) in a case where a determination is that user information identification transmitted with the request for the playing of said content from said playing position represented by said time stamp does not match the user identification information stored in association with the time stamp and (ii) in a case where a determination is that a confirmation of an access right by user identification information is not necessary; and

providing, via the network, the content from the playing position represented by the time stamp in accordance with a result of the judging,

wherein said information management apparatus is to connect by way of said network to at least one information processing apparatus, and wherein said playing position represented by said time stamp corresponds to a stopped position whereat a user requested that said content be stopped by use of said at least one information processing apparatus.
