  • Publication number: 20070047546
    Abstract: In a virtual LAN, a packet forwarding apparatus forwards IP packets and L2 packets using a single switch. The packet forwarding apparatus includes a switch that switches a media access control (MAC) packet using a MAC address of the MAC packet, and a packet format converter. The packet format converter converts a packet from an input and output unit into a packet having a MAC address according to information from the input and output unit, and converts a packet output from the switch to the input and output unit to a packet format compatible with the input and output unit according to the information of the input and output unit.

  • Publication number: 20050219467
    Abstract: To automatically adjust the quality of a projection image commensurate with the performance in-time deterioration and aging of projector component parts in an image projection system, each projector detects an integrated service time of its own light-source lamp and a service time and temperature of a liquid-crystal panel, and sends a detection result thereof to a control unit in compliance with a request from the control unit. These parameter values are parameter values having an effect upon the quality of a projection image and varying with time. The control unit copes with the projectors depending upon the detection result received from the projectors, to set predetermined control data for use in image-quality adjustment and send the control data respectively to the projectors. Each projector controls the driving to its light-source lamp and liquid-crystal panel, depending upon the control data received from the control unit.
