Abstract: An on-vehicle equipment mounted on a vehicle and adapted to receive a data broadcasting transmitted in digital broadcasting and display it on a display unit, holds a contents of the data broadcasting in correspondence with a combination of component tag value and module ID for discriminating the contents, displays, in accordance with layout information of defaults containing information indicative of areas on the screen of display unit at which contents are displayed, a corresponding contents on the screen of the display unit, and acquires, when a combination of component tag value and module ID is received, a contents corresponding to the combination of component tag value and module ID and displays the acquired contents on the screen of display unit in a size larger than that for display pursuant to the default layout information.

Abstract: Provided is a digital broadcast receiving device (20) which can display a high resolution image longer without burdening users with a cumbersome operation. The digital broadcast receiving device (20) of the present invention switches, based on vehicle information, between switching thresholds by which switching is made between plural digital broadcast decoders outputting different digital broadcast images from one another in accordance with a reception state of digital broadcast waves. The plural digital broadcast decoders include, for example, a stationary reception decoder (200), which outputs a digital broadcast image for stationary receivers, and a mobile reception decoder (201), which outputs a digital broadcast image for mobile receivers.

Abstract: In a digital broadcast multiplexing apparatus for multiplexing a plurality of programs on a single physical channel so as to broadcast the digital multiplexed broadcasting program, there are provided with an apparatus for correcting positions of PCR packets contained in transport streams within the respective programs, and a PCR correction value forming apparatus for applying values of correcting PCR values with respect to a result of the position corrections in order to simply execute a function capable of uniformly synchronizing the PCR packets contained in the transport streams and capable of viewing the received programs without any interruption on the reception side even when a tuning operation is carried out. Then, the digital broadcast multiplexing apparatus outputs such a broadcast program packet stream which has been multiplexed as a single broadcast program in such a manner that the PCR packets are synchronized with each other among the plurality of programs.

Abstract: In the digital broadcast to a mobile unit, the continuous reproduction of an image cannot be guaranteed when switching the hierarchical level in accordance with the receiving condition of the radio wave and therefore the viewer has a sense of discomfort. A digital broadcast sending apparatus sends out by encoding a plurality of simultaneous broadcast streams in the same sync signal generator. A switching determination unit of the receiving apparatus switches the plurality of simultaneous broadcast streams in accordance with the receiving condition (weak hierarchical level/strong hierarchical level), and a sync adjustment unit continuously displays an image without interruptions based on the received sync signal. At the time of this switching operation, one stream is gradually switched to the other.

Abstract: A digital broadcast receiving apparatus receives a digital broadcast signal, which consists of layers each obtained by dividing a transmission bandwidth into a plurality of segments and combining some of the segments, and outputs images and/or sound from one of the layers constituting the received digital signal. This apparatus is characterized by comprising broadcasting format retention means (channel to broadcasting format correspondence table database) for retaining the broadcasting format, for each layer, of each broadcast station and switching means (layer switching means) for switching the output layer based on the broadcasting format, for each layer, of each broadcast station retained in the broadcasting retention means. Thus, this apparatus can output images and sound without interruption.

Abstract: A digital broadcast receiver (mobile's receiver terminal) 1 for receiving a digital broadcast signal DS carrying many contents and also outputting the content based on thus received digital broadcast signal DS, including a content accumulation portion (database) 1c for accumulating received contents, a reception state detection portion for detecting whether the digital broadcast signal DS can be received normally, and a switch-over portion (reproduction/switch-over portion) 1b for switching from output of the content received to reproduction of the content accumulated in the content accumulation portion 1c if the reception state detection portion detects that the digital broadcast signal cannot be received normally.

Abstract: With regard to electric-power-supply control, there is provided an electric power supply control system for implementing load control used to be executed for each individual customer consuming electric power as coordinated control for all customers and for selecting an optimum electric-power supplier in case there are a plurality of electric-power suppliers supplying electric power to the customers.

Abstract: In an advertising system where contents to be displayed are sent to display devices by digital broadcasting and the contents are displayed on sheet-shaped visual display units, when data update complete reply messages for confirming that specified advertisement has been displayed are communicated, channel congestion may arise due to simultaneous replies sent from a great number of information display devices. A display confirmation server is provided for confirming that information display has been updated on each information display device. Each information display device sends a reply message that display has updated to information received by digital broadcasting to the display confirmation server. At this time, each information display device waits for a randomly set wait time after changing information display before sending the reply. The display confirmation server that received the reply messages from the display devices reports data update complete on behalf of the display devices.

Abstract: A relay station comprises an emergency information detection unit for detecting an emergency information broadcasting flag in the digital broadcasting TMCC signal transmitted from the center station; a replacement data creation unit for issuing an instruction for creating replacement contents and replacing the data when emergency information is multiplexed in the TS; and a time synchronization unit for executing time synchronization between the TS created by the data replacement and the TS before the data replacement. On a receiving terminal, the replaced data broadcasting contents can be received while prefectural broadcasting video and audio contents are continuously received.

Abstract: A communications-type car navigation system including a vehicle-mounted terminal and a server. When transferring, to the terminal, the result of a route searching which the server has performed, the server transfers the data that will satisfy the requirements of a route guiding method which the user wishes. Also, the server transfers the route data that has been compressed. Concerning the map data as well, the server transfers only the necessary attributes thereof. Moreover, the following conditions allow the operability to be enhanced: the selection of a map transferring method and the route guiding method where the driving state has been taken into consideration, and the selection of a guiding unit which the user wishes.

Abstract: A broadcast content that is at least a part of an original content is broadcasted, and a differential content, which is at least a part of the original content, is transmitted in response to a request from a reception terminal. The differential content and the broadcast content are merged with each other to reproduce a perfect original content. Therefore, the perfect original content can be obtained at low price and in short time even when the original content contains a large amount of data.
