Abstract: This invention is a technique for automatically generating a suitable digest of the content, which can attract the interest of many viewers. This invention comprises the steps of: acquiring user instruction information associated with a specific content, such as information concerning a re-viewing desired range designated by the user and information concerning a delivery request for the specific content, from a user terminal that is a delivery designation; and generating a digest of the specific content based on at least the user instruction information. Moreover, this invention may further comprise a step of acquiring information concerning a scene change of the specific content, and in the digest generating step, the digest may be generated based on the information concerning the scene change and the information concerning the delivery request of the specific content. This is because the digest is made not to start from a halfway place in the middle of the scene.

Abstract: A bus load distributing method suitable for data communications equipment and a bus switching control device for data communications equipment. The data communication equipment includes plural buses, a bus connecting unit for interconnecting the plural buses, and a control unit for connecting physically and selectively each module to one among the plural buses. The control unit connects plural modules to a bus to recognize, distribute and reduce the load on the bus. The control device also switches a bus to be connected in accordance with the traffic of each module to optimize the bus load.

Abstract: In measuring the distance and the positional relationship between the equipments on a LAN, a first equipment transmits a request packet to each of the other equipments at a predetermined interval of time. When each of the other equipments receives the request packet, it supplies the response packet to the first equipment. The first equipment calculates the distance between the first equipment and each of the other equipments on the basis of the time at which the request packet has been transmitted and the time at which the response packet has been received, and stores the calculated distance in the network structure information table NWT. Since the packet transmission speed changes in accordance with the traffic volume, the calculated distance is compared with the distance stored in the network structure information table NWT, and only when the calculated distance is shorter, it is stored in the network structure information table NWT.
