An information processing system, apparatus, method, and medium in which the purchase of content is facilitated. When a device to which content data is downloaded and a device for giving an instruction to purchase the content data are different, a purchase form for purchasing the content data is sent to the device giving an instruction to purchase the content data. The user ID and password are input into the purchase form, and the device to which the content data is downloaded, is determined by the user ID. If the device to which the content data is downloaded cannot be specified because the user registers a plurality of devices, a destination determination form specifying the device to which the content data is downloaded, is sent. The content data is then distributed to the device indicated in the destination determination form.

Information processing system, information processing apparatus, method and program

The present invention relates to an information processing system, an information processing apparatus and method, and a program in which the purchase of content can be facilitated. When a device to which content data is downloaded and a device for giving an instruction to purchase the content data are different, a purchase form for purchasing the content data is sent to the device for giving an instruction to purchase the content data. The user ID and password are input into the purchase form, and the device to which the content data is downloaded is determined by the user ID. If the device to which the content data is downloaded cannot be specified because the user registers a plurality of devices, a destination determination form for specifying the device to which the content data is downloaded is sent. The content data is then distributed to the device indicated in the destination determination form. The present invention is applicable to a server for executing processing concerning content data.

There are provided an information recording medium, an information processing apparatus, an information processing method, and a computer program, which can realize users' convenience for using content in accordance with a license and copyright protection. An information recording medium stores an encrypted content file including encrypted content, usage right information of the encrypted content, and encryption key information necessary for a decrypting process for the encrypted content. Thus, a user can acquire a license (usage right information) and key information necessary for decryption of the content, together with the content, from the information recording medium, without acquiring the license (usage rights) by connection to a license provider. Therefore, it is no longer necessary to perform a process of acquiring the license (usage rights) from the license provider when the content is to be used, whereby user convenience is improved, and license-based content copyright management can also be ensured.

Information recording medium and information processing method for accessing content with license or copyright protection

Information recording medium, information processing device, information processing method, and computer program

Upon receiving a request for distribution of content data, determination is made whether or not the transmission can be performed, based upon a transmission reservation table. If a user has specified the transmission point in time, a transmission device refers to the reservation state corresponding to the specified point in time, and if available, the transmission device makes a reservation for the specified transmission point in time. Otherwise, the transmission device makes a reservation for an available transmission point in time near the specified point in time, as appropriate. If the user has not specified the transmission point in time, the transmission device transmits the content data at an available point in time, as appropriate. If the transmission device cannot acquire predetermined information, and accordingly cannot determine the transmission point in time, the transmission device generates a schedule indicating that the transmission point in time has not been fixed.
