Patent number: 8311736Abstract: A navigation device receives a differential map data from a map delivery server via a communication line. The map delivery server checks whether there is a new intersection on a navigation route searched by the navigation device after updating a map data. The navigation device acquires a differential map data containing the intersection from the map delivery server. Then, an update map data selection section determines whether the intersection can be updated in time. An update order determination section updates the differential map data which can be updated in time in ascending order of time required to reach the intersection.Type: GrantFiled: June 4, 2009Date of Patent: November 13, 2012Assignees: Hitachi, Ltd., Clarion Co., Ltd.Inventors: Osamu Tomobe, Yukihiro Kawamata, Yukio Miyazaki, Takayoshi Shimokawa

Patent number: 7580612Abstract: 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.Type: GrantFiled: October 14, 2005Date of Patent: August 25, 2009Assignee: Hitachi, Ltd.Inventors: Yoshihito Sato, Osamu Tomobe, Takaharu Ishida, Hiroki Uchiyama
