Abstract: An information preparation device, such as a personal computer, detects non-consecutive position information, such as times and dates, based on parameters (S11), such as preinputted non-consecutive point detection margins, and prepares (S12) an information table with image information for each non-consecutive position. Based on editing parameters, the device synthesizes and edits (S13) the information in the information table by date and the like. Then the device divides the information into objects, which is a data format, by data The device retrieves contents information and the like that corresponds to the divided information, and generates (S14) and outputs (S15) scenario information. The date and the like indicated by the divided regions serve as an index on buttons of menus that the user operates to easily select and display a desired images.

Abstract: A video image edit device for editing video image contents recorded on a video tape. The video tape is rewound to its leading end and a start point time code and a maximum video image content period are stored in a RAM. Then, a video reproduction is started and a time code and time information for a video image content are retrieved. A difference between the present time and a precedent time is compared with a predetermined period to detect discontinuity of the video image content. If discontinuity cannot be detected, judgment is made as to whether or not a difference between the present time code and a start point time code exceeds the maximum video image content period to determine a subdivision point. If discontinuity is detected, or if the difference exceeds the maximum video image content period, a present end point time code and next start point time code are stored for again detecting the discontinuity or judging the next subdivision point.

Abstract: An information generating apparatus of the invention generates disk information by a playback control information generating device based on scenario information input by a scenario information input device and stores the disk information on a storage device. The information generating apparatus also generates video file management information based on information that is found from the scenario information and stores the video file management information on the storage device. On the other hand, video or audio data that are input by a video data input device or an audio data input device are encoded by a video data encoding device or an audio data encoding device and are multiplexed by a multiplexing device. By doing so, a system stream is generated and stored on the storage device. Every one system stream is generated, the rest of the video file management information is generated and stored on the storage device.

Abstract: A multilingual transmission system includes a server device and a client device. The server device analyzes the meaning and grammatical significance of a source text in a natural language. When vagueness exists in the source text, the server device displays different candidates corresponding to different interpretations of the vague source text, so that the user can select which interpretation is correct. The server device produces pivot language data accordingly and stores it. When the client device requests text data, the server device retrieves pivot language data corresponding to the requested text data. Based on the retrieved pivot language data, the server device generates target language text data in the language requested by the client device and transmits the generated target language text data to the client device.

Abstract: In an image processing apparatus comprising an image reading device, a control unit, a display unit and a print device, the entire image data read by the image reading device is displayed on the display unit. The periphery of the image data is arbitrarily trimmed on the display unit by operating a mouse controlled by the control unit. Next, the dividing position of the trimmed image is arbitrarily selected by operating the mouse controlled by the control unit so that the dividing position should not pass through an important part of the image. Each portion of the divided image data is printed out by the print device, and then all divided images are manually adhered by the operator. Therefore, a maximum size of the print image can be obtained, even when the size exceeds the possible print size of the print device.
