| 20080204358 | INFORMATION DISTRIBUTION SYSTEM, INFORMATION DISTRIBUTION METHOD, AND INFORMATION DISPLAY DEVICE - 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. | 08-28-2008 |
| 20080209466 | BROADCASTING DATA CONVERTER - 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. | 08-28-2008 |
| 20090190668 | DIGITAL BROADCAST RECEIVING APPARATUS - 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. | 07-30-2009 |
| 20090232165 | DIGITAL BROADCAST MULTIPLEXING APPARATUS - 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. | 09-17-2009 |
| 20090320079 | ON-VEHICLE EQUIPMENT FOR RECEIVING AND DISPLAYING DIGITAL BROADCASTING - 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. | 12-24-2009 |
