    摘要: A method of information processing in a server/client system including a server for storing content and a client for receiving from the server and storing copy content of the content stored in the server. The method includes the steps of: the server generating at least either a content-ID list storing content-IDs corresponding to content for which use-expiration-date updating is permitted out of the copy content stored in the client or a content-ID list storing content-IDs corresponding to content for which use-expiration-date updating is not permitted, transmitting the content-ID list to the client; and the client selectively performing update processing of use-expiration date out of the copy content stored in that client or invalidation processing of the copy content stored in that client based on the content-ID list received from the server.

    摘要: An information processing apparatus operating as a content use management server is disclosed. The apparatus includes a storage unit for storing a license as information for granting rights to use content and content attribute information, and a data processing unit for carrying out a content state shifting process in which to shift content usable states. The content usable states are formed by a bound state and a discrete state. The bound state refers to the state in which the content is allowed to be used by any of member clients on a local network of which the content use management server is a part. The discrete state refers to the state in which the content is allowed to be used only by a member client retaining the license for granting rights to use the content. The data processing unit updates descriptive information on the license and the content attribute information stored in the storage unit in order to shift the two content states.

    摘要: Transmitting apparatuses, transmitting methods, receiving apparatuses, receiving methods, and transmitting and receiving systems for transmitting and receiving a hierarchical structure of a directory for hierarchically managing locations of contents data is disclosed. The apparatuses, methods and systems manage a hierarchical structure of a directory composed of a container entry and a leaf entry. The container entry contains information of the lower hierarchical level thereof, a leaf entry being located directly below a container entry. The leaf entry does not contain information of the lower hierarchical level thereof.

    摘要: Digital apparatus for convergence correction of a plurality of images on the screen of a television monitor includes a digital registration circuit, or an analog registration circuit using a digital attenuator; and a memory for storing data for operation of the digital registration circuit or the digital attenuator of the analog registration circuit. The memory has a plurality of pages, and the correction data corresponding to different operating conditions is stored in the respective pages of the memory. The paging of this memory is performed in accordance with the operating conditions, and the convergence correction is carried out on the basis of the correction data continuously read out of the designated page. With this apparatus, accurate convergence adjustment can be simply performed to accommodate changes in size and/or shape of the image displayed on the screen or monitor, changes in the distance of a projection screen from its projector, and changes in the screen surface, i.e., flat, concave, cyindrical, etc.
