摘要:
In a network arrangement implementing a virtual interface scheme to execute various types of application processes using plural control units, the routing tables of the control units may be synchronized without having to execute a complicated process sequence. In a network apparatus including a forwarding unit corresponding to a base point for conducting packet transmission/reception with an external network, and plural control units for operating plural applications that are arranged to access virtual interfaces of the control units that correspond to actual interfaces of the forwarding unit so that the network apparatus appears from the outside to be functioning as a single unit. A routing process of generating a routing table is executed at a master control unit corresponding to one of the control units, and if the routing table of the master control unit is updated, a routing table of the forwarding unit is updated by a routing synchronization process that operates independently from the routing process. One or more routing tables of one or more slave control units corresponding to the control units other than the master control unit are updated through the forwarding unit.

A buffer control system is a system for implementing both a priority control process and a shaping process of cells with a hardware configuration of a small size in a network routing fixed-length packets which are respectively composed of transfer data and control information added to the transfer data, and to which priority information is assigned, according to the control information. If a cell written to an empty area of a cell buffer is a prioritized cell, and its expected output time is a time slot, an address where the cell is stored in the cell buffer is arranged in a time slot in a prioritized cell entry memory. When it reaches the time to read the cell stored in the time slot, the address stored in the time slot is written to an output list chain, and the cell is read from that address. The empty area of the buffer is managed using a free list chain.

A stereoscopic image display apparatus for displaying a stereoscopic image, which is obtained by alternately arranging stripe parallax images R and L corresponding to the right and left eyes, in a window includes a parallax barrier for a stereoscopic vision. When the display position of a window including a stereoscopic image which is set after the window is opened or moved and the positions of the right-eye and left-eye stripes of a parallax barrier have a relationship which does not allow a proper stereoscopic vision, the display position of the window is moved by one stripe in the horizontal direction.

摘要:
A stereoscopic image display apparatus which can reproduce two-dimensional images of high resolution corresponding to a number of viewpoints, for displaying a three-dimensional image, by using a minimized number of light sources. The stereoscopic image display apparatus comprises a light deflection member which has a deflection element deflecting a light beam from a light source unit to form a convergence point, and a beam scanning device which two-dimensionally scans the light beam from the light source unit with respect to the light deflecting member. The light deflection member is movable. The movement of the light deflection member is preformed in synchronization with modulation of the light beam by the light source unit and the scanning of the light beam by the beam scanning device.
