摘要： The multicast communication scheme which can enable a user to easily comprehend the multicast groups existing on the network, easily carry out an operation to join a desired multicast group, and easily specify a desired communication quality. At each user terminal, a virtual space with a plurality of regions defined therein in correspondence to a plurality of multicast groups is displayed on a screen, while an information indicating a range of each region in the virtual space is stored in correspondence to an address information for a corresponding multicast group. A desired position in the virtual space on the screen is specified by an input device, and joining/leaving to/from multicast groups is controlled by using the address information stored in correspondence to a region in the virtual space which contains the desired position. The display on the screen may include a plurality of zones defined within each region in correspondence to a plurality of different communication qualities, so that a communication quality of a multicast communication to be received can be controlled according to a zone within a region in the virtual space which contains the desired position.

摘要： According to one embodiment, a representation converting unit converts a set of n elements (h0, h1, . . . , hn−1) (hi: a member of a finite field Fp^m, 0≦i≦n−1) that is a projective representation of a member g of an n-th degree algebraic torus Tn(Fp^m) (n: positive integer, p: prime number, m: positive integer) into a limited projected representation expressed by a set of n elements (h′0, h′1, . . . , h′n−1) (h′i: a member of the finite field Fp^m, 0≦i≦n−1) in which at least one element out of the n elements is a zero element 0 or an identity element 1. An arithmetic unit omits part of Fp^m operation that is arithmetic operation in the finite field Fp^m based on a fact that an element in the set of n elements (h′0, h′1, . . . , h′n−1) represented by the limited projective representation is a zero element “0” or an identity element “1” when performing Fp^mn operation that is arithmetic operation of a finite field Fp^mn in combination with the Fp^m operation.

摘要： A compressing unit compresses an element on an algebraic torus into affine representation according to a compression map. A determining unit determines whether a target element on the algebraic torus to be compressed is an exceptional point representing an element on the algebraic torus that cannot be compressed by the compression map. The compressing unit generates, when it is determined that the target element is the exceptional point, a processing result including exceptional information indicating that the target element is the exceptional point, and generates, when it is determined that the target element is not the exceptional point, a processing result including affine representation obtained by compressing the target element according to the compression map.

摘要： Residue calculating sections respectively obtain residues which take a plurality of integers as modulus, with respect to a user ID. The plurality of integers are stored in modulus storage sections and are prime to each other. Based on these residues and parameters stored in a coding parameter storage section, component codes constructed by continuous sequences of 1 and 0 using a predetermined number of bits as a unit are respectively generated by component code generating sections. These component codes are concatenated by a concatenating section, thereby to obtain a code to be embedded, which constructs watermark information.
