摘要： PROBLEM TO BE SOLVED: To provide a system wherein a management device side performs assignment of a target and a LU (Logical Unit) such that access does not concentrate upon a specific storage device and a specific port.
SOLUTION: The management device selects a storage device having a lot of unassigned storage area, selects the target using a port having a small number of assignment number among the targets of the storage device, and to assign the target, an initiator, the storage area. The management device manages the storage device as an assignment candidate when the assignment number of the storage area and the target prepared by the storage device is a prescribed value or below. and excludes the storage device from the assignment candidate when it exceeds the prescribed number. When the number of the storage devices excluded from the assignment candidate reaches a prescribed number, the management device manages a new storage device and a new storage area as an assignment number candidate.

摘要： PROBLEM TO BE SOLVED: To actualize the distribution of hierarchical encoded video data which can discard only specific hierarchical data when one piece of video program data consisting of plural layers is distributed over one channel.
SOLUTION: The hierarchical encoding of a video signal is performed on an MPEG basis (21) and packetized elementary stream packetization, real-time protocol packetization, and user data program protocol(UDP) packetization are performed by the layers for elementary stream data. (22). The UDP packet data are given identifiers by the layers and Internet protocol packetization is performed (23). Consequently, only packets carrying data exerting small influence on pictures can be discarded if a transmission network is congested.

摘要： PROBLEM TO BE SOLVED: To provide a program transmission reception system where programs of plural qualities are reproduced from one stream in the case of receiving/ reproducing a video program. SOLUTION: A program distributor 30 sends packets in which hierarchical coded program data are provided with an identifier for every hierarchy, to a program quality converter 20 existing at an edge on a network and branched to reception terminals 11, 12. The program quality converter 20 reproduces and converts the hierarchical code program data in response to the quality requested by the reception terminals 11, 12 and distributes the reproduced and converted program data to the each reception terminal. Thus, the programs of plural qualities are reproduced from one-stream data in which the program is coded.

摘要： PURPOSE:To apply presence by specifying the persons in charge of conversation (a speaker and a speaking partner) at a multi-spot video conference system. CONSTITUTION:A correlation analysis circuit 9 specifies the conversation party of its own video conference site 32 based on the strength of correlative relation between an acoustic signal (as) generated at its own video conference site 32 and acoustic signals a1-a4 generated at other video conference sites 1, 2.... A system controller 10 selects a video signal photographed by a camera close to the video display position of the specified conversation party. Thus, presence can be improved by matching glances between conversation parties each other.
