摘要:
A data processing apparatus according to the present invention is capable of writing video and/or audio data to a storage medium. The data processing apparatus includes: a power controller for controlling powering on or off; a signal processing circuit for generating data; and a drive section for writing the generated data to the storage medium. In response to a powering-off instruction, the power controller stops supplying power to the drive section but continues to supply power to the signal processing circuit and the power controller itself. Since hardware elements remain energized, they do not need to perform initialization operations when the apparatus is powered on. Similarly, corresponding software elements are also in an operable state, and therefore do not need to perform initialization processes. Therefore, the signal processing circuit can immediately start processing thereafter.

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.
摘要:
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.

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 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.
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.
