A digital content operating apparatus, including: a communication unit which communicates with an external device which has a display for displaying the digital content; a user operation interface which receives a user operation to control the digital content which is displayed on the external device; a display which displays either a linear content operation panel or an interactive content operation panel; and a controller which controls the user operation interface corresponding to information on the digital content which is displayed on the external device; wherein either the linear content operation panel or the interactive content operation panel is displayed alternatively as the user operation interface on the display.

To improve determination accuracy of determining whether a user is present in a house. A presence-in-house determination systemincludes: a first presence-in-house determination unitconfigured to determine whether the user is present in the house based on a change over time in electric power consumption of the house of the user; second presence-in-house determination unitsA andB configured to determine whether the user is present in the house based on an operation state of at least one of electric appliancesA andB provided in the house; and a comprehensive determination unitconfigured to determine whether the user is present in the house based on a determination result of the first presence-in-house determination unit and a determination result of the second presence-in-house determination unit.

Presence-in-house determination system and presence-in-house determination method

A terminal display device which a user wears on a user's head displays on a display unit an information object to be overlapped with a field of view of the user, detects a motion of the terminal display device, and stores a pattern of a motion of the terminal display device and an operation content of the information object that is displayed in association with each other. An information type management memory unit stores information related to a display mode of each of the information objects. A display control unit determines an operation content of the terminal display device based on the motion that is detected and an association between the motion pattern and the operation content, specifies the information object disposed at a predetermined position of the display unit, and performs an operation specified with the determined operation content on the specified information object.

Video information, which is photographed with using a GPS built-in video camera, is inputted into a video information server. A video information correspondence table is produced, which associated photographing time of the video information inputted, data address of the video information photographed, and photographing position, and is memorized. According to a request from a display apparatus, the memorized video information correspondence table is searched, and thereby obtaining the video information having the information of time and position designated.

Video information control apparatus and method

A digital content reproducing apparatus is provided with a plurality of user operation interfaces, e.g., a linear content operation panel and an interactive content operation panel, a data monitor unit monitors information on digital contents, and upon occurrence of a change, the plurality of user operation panels are automatically and exclusively displayed in an operation panel display area. Accordingly, only usable operation keys can be displayed, user operation learning time can be shortened, since the panel rendering area is made small, a mouse motion distance can be shortened, and easy to use can be improved. Further, since the panel rendering area is made small, the image display area can be made relatively large.

A video recorder for recording a program video in a built-in HDD (hard disk drive) or the like on the basis of EPG data is easily put in a reserve-recording mode. To this end, reserve-recording candidate data is generated from the EPG data with use of recorded program information to facilitate selection of the reserve-recording mode. In a method for reserve-recording a broadcast program, similar program information is extracted from the EPG data on the basis of recorded title data held as the recorded program information, the extracted similar program data is converted to a data format usable for the reserve-recording, and is stored as reserve-recording candidate data upon reserve-recording.
