摘要:
A data conversion apparatus is provided as a data transmitting apparatus in a data communication system which achieves pseudo interactive communications by using one-way communications between the data transmitting apparatus and a plurality of data receiving apparatuses. The data conversion apparatus converts documents stored inside into images to be displayed on the screen, such as a TV screen. In doing so, if the document includes character strings or image information as link destination information which specifies another document as a link destination, the data conversion apparatus adds a supplementary design into the image of the link destination information for the viewer to recognize such information.
摘要:
A data conversion apparatus is provided for reading a document for a display screen and generating a display image for another display screen which has a different aspect ratio from the former display screen, where the document is composed of control statements written along with character strings or image information. The data conversion apparatus obtains the document from an external unit and converts the character strings and the image information in the document into display image elements based on conversion information. The data conversion apparatus judges whether a storage includes a blank for storing the display image elements at an appropriate position based on the conversion information. The data conversion apparatus writes the display image elements into the blank if it judges that the storing unit includes the blank; the data conversion apparatus assigns a new storage area in the storage and writes the display image elements into the new storage area if it judges that the storing unit does not include the blank.
摘要:
A data processing apparatus which displays a set of document data on a display unit together with an operation menu which has operation items related to the set of document data. In the apparatus, the document data storage unit stores a plurality of sets of document data of different contents which are indicated by sets of content information. The operation menu information storage unit stores a plurality of sets of operation menu information which each contain operation items that correspond to a content of document data. The first indication operation unit indicates a display of a set of document data. The second indication operation unit indicates an addition of a display of an operation menu to a display of document data. The operation menu generation unit receives an indication from the second indication operation unit, obtains the content information of the displayed data from the document data storage unit, extracts a corresponding set of operation menu information from the operation menu information storage unit, and generates an operation menu with the extracted operation items as menu items. The display control unit reads a set of document data from the document data storage unit, has the data displayed on the display unit in accordance with an indication from the first indication operation unit, and has the operation menu generated by the operation menu generation unit displayed in a window provided on the display unit.

A broadcast reception apparatus is provided with a reception unit for receiving broadcast data as a transport stream. The transport stream includes video data and a plurality of navigation information sequences. Each navigation information sequence includes navigation information which includes graphics data to be combined with the video data for display. A TS (Transport Stream) decoder unit extracts the video data and navigation information from the transport stream. A reception control unit controls the TS decoder unit so that the TS decoder unit extracts navigation information from a navigation information sequence which is suitable for the the broadcast reception apparatus. A navigation information storage unit stores the navigation information extracted by the TS decoder unit. A reproduction control unit combines graphics data included in the navigation information stored in the navigation information storage unit with the video data extracted by the TS decoder unit and displays a composite image of this combination. This achieves a broadcast reception apparatus which selectively uses necessary pieces of navigation information to display an image as a user interface.

A data display control apparatus receives a digital broadcast and compares the present time with a time indicated in a Time_Event_Part provided in navigation information used to control the display of the multimedia data composing a broadcast program. When the indicated time has been reached, the data display control apparatus executes instructions to control the display of the multimedia data.

A layout unit refers to a plurality of menu items stored in a menu item information storage unit by a menu item information obtaining unit. The following processes are performed as necessary to display a large number of menu items in a predetermined part of a GUI screen. A character size reducing unit reduces the size of characters used to display menu items. A margin reducing unit determines the layout of menu items so as to reduce the margins in menu items. An abbreviating unit replaces certain character strings in menu items with shorter character strings. In this way, the layout unit determines the layout of menu items. A menu control unit then has the menu items displayed in accordance with the layout determined by the layout unit.

A program conversion device includes a formal initialization expression generating unit, an actual initialization expression generating unit, and an object generation statement translating unit. The formal initialization expression generating unit focuses on a definition of an object generation function written in a source program and generates, if the object generation function does not perform any processing other than setting values in member variables of an object, a formal initialization expression which is the member variables represented by formal parameters. The actual initialization expression generating unit focuses on an object generation statement and generates, if a formal initialization expression that corresponds to an object generation function to be invoked by the object generation statement has been generated, an actual initialization expression. If the generated actual initialization expression is member variables represented by constants, the object generation statement translating unit translates the object generation statement in focus not into a subroutine call code sequence to invoke the corresponding object generation function, but into object data that has the constants of the actual initialization expression.
