    摘要: An object of the present invention is to provide technology in which an HA is capable of efficiently maintaining registration information of an MR, and communication efficiency in registration/update processing between the HA and the MR is improved. A mobile node has a representative home address, a subsidiary home address, and a care-of address, and registers information (joint information) showing the relation between the representative home address, and all subsidiary home addresses, and the care-of address with the home agent, each time the mobile node moves to other network and is assigned a new care-of address. The home agent receives a registration request for the joint information, and stores the registered information, and if a packet destined for the representative home address, or any subsidiary home address arrives from any correspondent node, retrieves the joint information including the address from the registered information maintained thereby, and transfers the packet to the corresponding care-of address.

    摘要: A data recording method is provided. The data recording method includes the processes of: receiving multiplexed data including a plurality of programs from an external source; extracting at least one program out of the programs included in the received multiplexed data; and recording the extracted at least one program, wherein each of programs is divided into a plurality of packets, and the programs are time-division multiplexed as the multiplexed data by a unit of the packet. The extracting process includes the processes of: extracting the packets composing the at least one program to be extracted from the multiplexed data; generating packet number data indicating the number of the packet which is a part of the program except for the at least one program to be extracted from the multiplexed data, and which is located in the multiplexed data and located between the packet previously extracted in the packet extracting process and the packet currently extracted in the packet extracting process; and recording the packets extracted in the packet extracting process and the packet number data generated in the generating process.
