Abstract: The present invention is an information processing apparatus adapted to a user interface that enables non-contact operation according to a screen displayed on a display. The information processing apparatus includes an input operation identification unit that identifies predetermined input operation on the basis of a sequence of position information of a specific part of a user in a predetermined spatial coordinate system, and a processing execution unit that executes predetermined processing on the basis of identified the predetermined input operation. The input operation identification unit identifies the predetermined input operation in a case of judging, on the basis of a second sequence of the position information, that the specific part of the user is in a moving state after the specific part of the user is in a staying state at a reference position in the predetermined spatial coordinate system on the basis of a first sequence of the position information.

Abstract: [Object] To unify the management of an access authority to contents in a theater not depending on a wide variety of complicated OS protocols. [Solving Means] The owner group setting unit sets a group per area (path) where a content is placed. The affiliation group setting unit sets a group accessible by the user. The content owner filter unit filters contents accessible by the user in accordance with the settings of the owner group setting unit and the affiliation group setting unit. The content kind setting unit sets a content kind accessible by the user. The content kind storing unit stores the content kind acquired by the content kind acquisition unit. The content kind filter unit filters contents accessible by the user in accordance with the setting of the content kind setting unit based on the content kind acquired by the content kind acquisition unit.

Abstract: There is provided a screening management system including a content accumulation unit for accumulating a plurality of video contents to be screened, a playlist management unit for managing a playlist defining an order of screening the video contents accumulated in the content accumulation unit and managing a file indicating one or a plurality of video contents to be screened in a specific place in the playlist, and a schedule management unit for managing the playlist according to a screening time. The playlist is a list in which a plurality of frames are arranged, and video content to be screened is indicated by a first frame among the plurality of frames, and the file is indicated by a second frame among the plurality of frames.

Abstract: An information processing apparatus includes a communicating section that executes communication with a server, a local storage section that stores subsequent data acquired from the server, and a data processing section that executes an acquisition process of the subsequent data, and a data playback process using data stored on a disc and the subsequent data stored on the local storage section. The data processing section builds a virtual file system for reading data stored on the disc and the local storage section, at the time of the data playback process, and performs the acquisition process of the subsequent data by transmitting a package ID to the server at the time of the acquisition process of the subsequent data, the package ID being information specifying a package corresponding to a file set necessary for building or updating the virtual file system.

Abstract: Disclosed herein is an information processing apparatus that serves as a server that performs data transmission in response to receipt of media information from a user device. The information processing apparatus includes: an encrypted transmission data storage database that stores a transmission data identifier and encrypted transmission data such that the transmission data identifier and the encrypted transmission data are associated with each other; and a control section configured to acquire, from a key management server, an encrypted unit key obtained by encrypting a unit key that is used to encrypt the transmission data, and transmit the acquired encrypted unit key and the encrypted transmission data to the user device.

Abstract: An information processing apparatus includes a measuring unit, a transmitter, and a receiver. The measuring unit first measures the performance of the information processing apparatus. The transmitter then transmits measurement results in the form of information indicating the performance measured by the measuring unit, together with a content request requesting desired content, to another information processing apparatus. The receiver subsequently receives content from the other information processing apparatus that has been supplied according to the content request and selected on the basis of the measurement results. In so doing, the information processing load is suitably adjusted according to the performance of the information processing apparatus.

Abstract: An audio playing apparatus that plays a multiplexed audio stream resulting from the multiplexing of multiple kinds of audio is disclosed. The apparatus can be switched at least between a mixing output mode for mixing decoded data or uncompressed data of the audio streams of multiple kinds of audio and outputting the result to one audio output terminal and a separate output mode for outputting the audio streams of multiple kinds of audio to separate audio output terminals independently.

Abstract: A content recording medium includes a content recording area where content data is recorded in such a manner that playback of the content data is restricted; and a playback-permission-information recording area where playback-permission information that allows canceling the playback restriction of the content data to permit playback is to be recorded, the playback-permission-information recording area being provided separately from the content recording area.
