Abstract: A device collaboration system includes a server 1 that manages contents, a main communication terminal 10 capable of making access to the server 1 via a network and reproducing a content, and an auxiliary communication terminal 20 capable of making access to the server via the network 30. The server monitors a reproduction state of a content reproduced by the main communication terminal 10, and when the main communication terminal 10 reproduces a predetermined portion in the content, the server controls an action by the auxiliary communication terminal 20.

Abstract: A communication service system includes a SNS server 1 that manages contents, and client terminals 10 to 30 that can make access to the SNS server 1 via a network 40. Each of the client terminals 10 to 30 includes a portion with which the client terminal can obtain an object. The SNS server 1 manages objects input by the client terminals 10 to 30, and allows a plurality of client terminals that are connected to the network 40 and browse the same content to share objects.

Abstract: A content display system includes a client terminal for displaying contents and a server for managing the contents. The server manages a display layer associated with each page of main contents. The server creates a new page of the display layer based on predetermined rules and arranges on the new page of the display layer subcontents associated with the main contents, and sends to the client terminal the main contents and the display layer on which the subcontents are arranged. The client terminal displays the display layer on which the subcontents are arranged together with each page of the main contents with which the display layer is associated to associate the main contents and the subcontents with each other.

Abstract: A content display apparatus comprises a display unit which displays a content which has a plurality of characters an order of which is regulated, a position directions unit which directs a position on the display unit, and a control unit which controls a display on the display unit, according to the position directed by the position directions unit and the order of the characters. At a first operation mode, when the position directions unit directs a first position on the display unit, the control unit makes the characters corresponding to the directed first position impossible to be viewed on the display unit. At a second operation mode, when the position directions unit directs a second position on the display unit, the control unit makes such characters possible to be viewed that were made impossible to be viewed and that are located before the directed second position under the order.

Abstract: A recording/reproduction device that prevents content and related content from being reproduced simultaneously. The recording/reproducing device (110) includes a recording area (115), a communication processing unit (119) outputting the related content having details identical to details of the content recorded onto the recording area (115) into an external recording medium (160), and an encoding/decoding processing unit (117) obtaining unique information of the external recording medium (160). The encoding/decoding processing unit (117) changes a state of content recorded in the recording area (115) into an irreproducible state unless the unique information of the content is used, when the related content is outputted to the external recording medium (160), and then reproduces the content recorded in the recording area (115) using the unique information, when the encoding/decoding processing unit (117) obtains the unique information.

Abstract: An electronic apparatus reads a digital data stream including a video signal and/or an audio signal outputted from an external apparatus according to a transmission clock different from a clock for the data stream, and outputs the video signal and/or audio signal without causing any discontinuity. The electronic apparatus includes a sample rate converter that rate-converts a predetermined volume of the audio signal in synchronization with a constant sampling clock, and changes a number of samples to be outputted, based on a data volume of an audio signal outputted by the electronic apparatus and a data volume of an audio signal transmitted from the external apparatus or transmittable from the external apparatus to the electronic apparatus.

Abstract: The present invention provides a recording and reproduction device capable of preventing content having details identical to the details of outputted content from being reproduced simultaneously with the outputted content, and allowing the content to be reproduced in high quality.
