Abstract: According to one embodiment, the host virtual machine includes a virtual bridge connection module configure to virtually connect one guest virtual machine and the network by bridge connection, a conversion modules configure to convert packets transmitted from the another guest virtual machines and the application to packets of a virtual private network (VPN) protocol, and a packet allocation module configure to detect a destination of the packets received from the network, to allocate the received packets to the virtual bridge connection module in a case where the detected destination is the one guest virtual machine, and to convert the packets of the VPN protocol received from the network to original packets and to allocate the converted packets to the detected destination in a case where the detected destination is any of the N?1 guest virtual machines and the application that runs on the host virtual machine.

Abstract: An electronic merchandise distribution apparatus includes an information management unit which acquires at least one of viewing information, preference information, and retrieval information of a user who uses one of a plurality of terminals, and a distribution management unit which stores non-real-time contents compressed by a CODEC, in an access provider corresponding to one of the plurality of terminals used by the user, based on the acquired at least one of the viewing information, preference information, and retrieval information of the user, prior to receiving the contents viewing request from the user.

Abstract: A viewer apparatus, content providing apparatus, advertisement providing apparatus, and electronic merchandise distribution system are connected to a network apparatus. Upon receiving excellent content information evaluated/analyzed by a content evaluation apparatus in accordance with a content buying request, a content buying apparatus in the distribution system transmits order data to the content providing apparatus, makes a content buying contract from replay data, and transmits a content and content information to a distribution apparatus. The distribution apparatus generates advertising space information from the content information, presents the advertising space information to the advertisement providing apparatus through an advertisement acquisition processing apparatus, and acquires advertising space sales, an advertising content, and advertising content information.

Abstract: An IP streaming system includes a headend system which has a navigation server, a distribution server which distributes a content with a high viewing frequency as a broadcast content, and a management server which holds the frequency band information of CATV cables for distributing the broadcast content, and a CMTS which is connected to the system via a network and accommodates a CATV cable to which a user terminal is connected. The CMTS has a cable interface having the frequency band of the CATV cable for the broadcast content. After the user terminal requests the frequency band information of the CATV cable for the broadcast content from the management server and acquires it, tuning to the acquired frequency band of the CATV cable is done, thereby distributing the broadcast content from the distribution server to the user terminal.
