A drawing processing apparatus and method wherein scrolling display which provides no sense of incongruity is achieved in 3D display. 3D information is produced using information in a drawing object range extracted as a predetermined range on map data. The drawing object range of an object of the 3D drawing process is moved in response to a scrolling operation. While the drawing object range is moved, 3D image data are successively produced using the drawing object range at every point of time and outputted to implement 3D display on a display screen. Thereupon, the drawing object range to be used for the 3D drawing is moved such that individual portions in the drawing object range are moved by movement amounts determined with reference to a distance in a perpendicular direction at a reference position in the drawing object range.

Drawing processing apparatus, display apparatus, drawing processing method and navigation apparatus

The present invention allows an existing single-sequentialized navigation main unit to be virtually multi-sequentialized with simple structure. An intervention devicereceives from a front monitorand a rear monitoracquisition requests which request various kinds of screens from a navigation main unit. In response to the acquisition requests, the intervention deviceperforms a mediating process or an adjusting process for various kinds of screens which are received from the navigation main unitand are scheduled to be output to the front monitorand the rear monitor. Therefore, even if the intervention devicereceives a plurality of acquisition requests from the front monitorand the rear monitor, the intervention devicecan sequentially send the acquisition requests one by one to the navigation main unit. Accordingly, this allows the navigation main unitto be virtually multi-sequentialized.

An improved transmission control method for use in a network which includes a time division multiplexing channel and a contention control channel. At least one station and a central control unit are connected both to a contention control channel and a time division multiplexing (TDMA) channel. When a station starts a time division multiplexing session, it transmits an access request to the central control unit via the contention control channel. After the central control unit receives the access request, the station which transmitted the access request is included in the order of the time division multiplexing (TDMA). The central control unit repeatedly transmits a transmission permitting token to the station via the TDMA channel in accordance with the order of the time division multiplexing. The station which received the transmission permitting token transmits the data entity, if existing, to either the other station or the central control unit via the second communication channel, and also transmits a transmission terminating token to the central control unit via the second communication channel. When the central control unit receives the transmission terminating token, it transmits the transmission permitting token via the second communication channel to the next station in the order of the time division multiplexing.

A cable network is constituted such that interconnectable, passive 4-terminal star couplers are connected to each other via optical fiber cables and a bi-directional optical relay amplifier. Cells each constituted by using free space transmission light are integrated by the cable network. An optical signal transmitted from or directed to a mobile station in a cell is linked to the cable network via an optical relay amplifier, which provides interface between free space transmission light and guided light. Even in a case where a barrier interposed between two mobile stations prevents a direct communication between those stations, a collision between those stations can be detected by a collision detection proxy server having functions of collision detection according to the principle of code transition rule violation and jamming signal transmission. A communication between those stations can be realized by connecting, to the cable network, a relay proxy server having a packet relay and transmitting function.
