  • Patent number: 7933334
    Abstract: The present invention provides an image coding method comprising: selecting prediction modes from among prescribed plurality of prediction modes based on processed blocks, the number of selected prediction modes being less than the number of said prescribed plurality of prediction modes; predicting a pixel of a block in an input frame image based on selected prediction modes; calculating a difference between said predicted pixel value and a pixel value of a block in an input frame; determining a coding mode based on the result of said calculation process, said determined coding mode being used for said image coding method. And the present invention also provides an encoding circuit, encoding program, a mobile terminal, an encoding and decoding circuit relevant to the image encoding method above.

  • Patent number: 6934281
    Abstract: There is disclosed a packet processing apparatus in which connection-oriented and connectionless data transfer systems are combined for use, and definite data transmission is secured even when a traffic load of a data transmission bus is large. An IP packet communication apparatus for using asynchronous and isochronous communication channels to perform a processing of an IP packet includes an address table for storing attribute information of the IP packet to be transmitted, each IP packet including information indicative of presence/absence of transmission in a fixed interval, a transmission monitor for periodically monitoring the information of the address table, and a CMP processor for receiving judgment information obtained by judging continuity of a traffic by the transmission monitor, and establishing the communication channel for asynchronous transmission.

  • Patent number: 6611873
    Abstract: A method for distributing service requests to a plurality of servers without any need for preparing a special measure in the clients or performing session management is disclosed. Addresses of a plurality of clients are classified in advance into a plurality of address groups. Each of the plurality of address groups is correlated with one of a plurality of servers. A service request of a client is distributed to a corresponding server depending on which address group the client belongs to.

  • Publication number: 20020009056
    Abstract: A route retrieving system is more effective than the conventional binary tree retrieval in IP transmission device. The route retrieving system determines a next node to transmit on the basis of a destination address identifying a communication counterpart. The system includes a route memory establishing a tree structure of respective node entry information and route data in hierarchal structure, the tree structure having a M branch tree structure (M=2N) to be checked per N bit (N is an integer greater than or equal to 2) from upper bit of the destination address and route retrieval means for retrieving the node entry information of the memory from an initial hierarchal stage to lower hierarchal stage in sequential order based on the destination address, for deriving a corresponding route data.

  • Patent number: 6233258
    Abstract: An ATM multicast communication system for identifying and multiplexing ATM cells at a receiving node by using AAL5 cell. This system has an insertion means for inserting ATM cell having RC (Routing Cell) with past record information or route information, when ATM cell of AAL5 is multiplexed. As multiplexing may occur several times on the communication line, RC acts not only as the identifier between the multiplexed cells, but also as the carrier of the past record of multiplexing. More specifically, the ATM cells transported from plural different input ports are multiplexed in the multiplexing equipment. Every time the destined input port is exchanged, the RC is inserted in front of said ATM cell. At receiving node, the RC is monitored, and the following ATM cells are distributed for each RC.
