Abstract: In a communication system comprising a communication device and a reproduction device capable of carrying out data communication with the communication device, the reproduction device includes a first storage unit in which content data are stored and a first communication unit engaged in data communication with the communication device, whereas the communication device in the communication system includes a second storage unit in which content data are stored, a second communication unit engaged in data communication with the first communication unit and a priority ranking determining unit that, based upon information obtained through the data communication and a priority ranking criterion, determines priority rankings for individual sets of content data in a content data group that includes both the content data stored in the first storage unit and the content data stored in the second storage unit.

Abstract: An information-processing apparatus, reproduction apparatus, communication method and computer program are disclosed wherein an evaluation value can be added automatically to contents stored in a storage apparatus or medium. The information-processing apparatus comprising an acquisition section which acquires, from a portable reproduction apparatus which is capable of reproducing contents data, reproduction history information of the contents data in the portable reproduction apparatus. An evaluation value arithmetic operation section arithmetically operates a computed evaluation value corresponding to the content data based on the reproduction history information acquired by the acquisition section. A transfer section transfers the computed evaluation value arithmetically operated by the evaluation value arithmetic operation section to the portable reproduction apparatus.

Abstract: Disclosed herein is an information-processing apparatus capable of transmitting a content to a portable reproduction apparatus which can reproduce the content, including: a content storage section; a transmission content acquisition section; a deletion completion list acquisition section; a transmission permission/inhibition determine section; and a content transmission section.

Abstract: In a centrifugal chamber 9, an elastic rotation shaft 30 and a high-rigidity rotation shaft 34 extend coaxially. When a rotor selected from an angle rotor 17 and a swing rotor 36 which have different sizes and shapes is set in the centrifugal chamber 9, an optimal shaft is connected automatically to the selected rotor. The angle rotor 17 having a low tendency toward mass eccentricity is supported and rotated by the elastic rotation shaft 30 for high-speed rotation. The swing rotor 34 having a high tendency toward mass eccentricity is supported by the high-rigidity shaft 34 for low-speed rotation. Rotation torque is transmitted to the swing rotor 34 from the elastic rotation shaft.

Abstract: The present invention relates to an apparatus and a method for information processing, a recording medium, and a program that can provide newest functions in a plurality of applications. A PC 1 reads a UD information file 14 including functional generation information of a setup program 13 from a loaded optical disk 3, and obtains a UD information file 16 including functional generation information of a setup program 15 registered in a server 4 via a network 2. Then, the PC 1 compares the functional generation information of the UD information file 14 on the optical disk 3, the UD information file 16 of the server 4, and a UD information registry 12, and updates an application program 11 and the UD information registry 12 using the setup program corresponding to the newest functional generation. The present invention is applicable to an information providing system that provides music content distribution service having a copyright managing function via a network.

Abstract: The present invention provides an information processing apparatus, an executability determining method and a computer program for the same. The information processing apparatus according to the present invention includes a list fetching section for fetching from outside disabled contents list information indicating disabled contents information disabling execution of an application program, when the contents data is subjected to a contents data reproducing/copying process for at least reproducing or copying the contents data, including a type and/or a version of the application program; and a verifying section for verifying a type and/or a version of an application program identified by referring to a starting file fetched together with the disabled contents list from the outside to at least one or more disabled contents information described in the disabled contents list information.
