Abstract: Equipment 1 includes a service provision functional unit 1f, an information processing unit 1e, a correspondence relation collecting functional unit 1c, a correspondence relation storage unit 1b, and a service request functional unit 1d. The information processing unit 1e has one or more objects, and provides control information to the service provision functional unit 1f by executing the object upon receiving a service request including a specific identifier. The correspondence relation collecting unit 1c collects a correspondence relation between the specific identifier of the object and address information of the equipment 1 from the equipment 1. The correspondence relation storage unit 1b stores the correspondence relation between the specific identifier and the address information, which is collected by the correspondence relation collecting unit 1c.

Abstract: A virtual LAN system forms a virtual group which is based on elements having physical attribute or logical attribute and constituting a virtual LAN, sets a client address and priority of the virtual group in a virtual group registration table, and allocates unicast and broadcast traffic bands in group units.

Abstract: A picture encoding system which performs a prediction of picture element values within a block having a plurality of picture elements into which an original picture is divided, a discrete sine transform with respect to prediction error signals for obtaining a transform coefficient, a quantization of the transform coefficient for encoding quantized indexes, an inverse quantization of the quantized indexes for reproduction of the transform coefficient, an inverse discrete sine transform of the reproduced coefficient to reproduce the prediction error signal, and an addition thereto of the predicted picture element value for reproducing the picture element values within the block to employ them in predicting a next stage block to be encoded, whereby the block can be minimized in size while simplifying required transform operation.
