  • Patent number: 7560975
    Abstract: The well voltage of a CMOS circuit having low-threshold-voltage MOSFETs is controlled when the power supply is turned on, during normal operation, and when the supply voltage is cut off. The CMOS circuit can thus operate stably with lower power consumption, because latching-up is reduced when the supply voltage is applied to the CMOS circuit or when the supply voltage is cut off, and subthreshold current is decreased during normal operation.

  • Patent number: 7558323
    Abstract: In a picture transmission network including networks of different transmission speeds, when a picture is sent at a bit rate which is adjusted to the transmission speed of a low-speed network, only a low-quality picture of a low bit rate is obtained in a video reception unit connected to a network of a high transmission speed. When a picture is sent at a transmission rate of a network having high transmission speed, the picture cannot be reproduced at all in a video reception unit connected to a network of a low transmission speed. To solve the problem, a video transmission unit generates at least an I picture data and a plurality of P picture data. In accordance with a request from the network, the I picture data and a predetermined number of P picture data is transmitted to the network.

    Abstract: A session relay apparatus for preventing the packet relay delay by detecting the start and end of the policy settable peer-to-peer communication is disclosed. The session relay apparatus for relay a session control message transmitted and received between communication terminals to control the peer-to-peer communication detects the start and end of the communication from the session control message, and acquires the information for identifying a session and the information on the peer-to-peer communication carried out on the session. Upon generation of a policy indicating the packet relay control process by a policy generating unit, edge nodes for passing the packet are searched for and the policy is distributed to the edge nodes. The policy is set in the edge nodes accommodating the communication terminals at the start of communication, and the policy setting is canceled at the end of communication.
