  • Publication number: 20120029893
    Abstract: A simulation system, method, and article of manufacture. A simulation system has a discrete and a continuous portion. The discrete portion further has a peripheral emulator in communication with the continuous portion of the simulation system. A portion of a peripheral emulator is separated and is caused to operate in a thread of a continuous system. The continuous system and the peripheral are in loose synchronization and therefore sparsely communicate with each other. The configuration significantly reduces the frequency of inter-thread communications between the continuous system and the discrete system that are performed in response to a continuous clock in a simulation system including the continuous system and the discrete system, thereby reducing communication cost. Accordingly, the operation speed of the simulation system can be increased.

  • Publication number: 20090306952
    Abstract: In a normal operation, a physical unit simulator is allowed to speculatively perform high-speed continuous execution. Only when an actual input comes in, a speculative input and the actual input are compared with each other. Thereafter, in response to inconsistency between the inputs, the physical unit simulator is returned to a point closest to the point of the actual input and is allowed to execute a variable step module to reach the point of the actual input. Upon arrival at the point of the actual input, the simulator is shifted back to the high-speed continuous execution from there. Thus, a processing speed of the simulator can be significantly improved.

  • Publication number: 20090241034
    Abstract: An object movement control system, an object movement control method, a server, and a computer program that can update the positional information of an object in a virtual space at high speed by appropriately distributing processing loads. Client control units obtain information about the position of a first object in a virtual space and information about movement of the first object and detect other objects that exist in a virtual region that contains the first object, which has been moved. The distances between objects that exist in a virtual region are calculated, and only when the number of objects the distances to which are shorter than a predetermined threshold exceeds a predetermined number, information about the objects is sent to a server. The server assigns a collision determination client that performs collision determination to each pair of objects selected from the objects.

  • Patent number: 7502863
    Abstract: A method and system which improves reliability and availability of services for streaming distributions in general. A partition server and a plurality of distribution servers are provided in order to distribute stream data to one or more receivers connected together via a network. The partition server receives the stream data and the plurality of distribution servers receive respective elements of the stream data partitioned by the partition server to distribute the elements to the receivers. First, the partition server selects one of the distribution servers that can perform transmissions in order to transmit elements of the stream data received from a streaming source, to the selected distribution server. The distribution server distributes the elements of the stream data received from the partition server, to the receivers. Finally, each receiver reconstructs the original stream data from the elements of the stream data received from the plurality of distribution servers.

  • Publication number: 20080117986
    Abstract: A method and system for embedding an electronic watermark directly in an MPEG stream is provided. An intra-macroblock of an I-frame or of a P or B-frame is detected in an MPEG stream, and following the detection of an intra-macroblock of the I-frame or of the P or B-frame, data for one macroblock are extracted from the MPEG stream and buffered. An embedding pattern is embedded in the buffered macroblock without changing the length of VLC, and the resultant macroblock is returned to the MPEG stream. More specifically, a DC factor is extracted from the buffered macroblock, and a pseudorandom number is generated to produce an embedding pattern. Then, whether the bit length of the DC factor will not be changed by embedding the obtained embedded pattern is determined. When the bit length of the DC factor not be changed, the embedding pattern is embedded in the buffered macroblock. When the bit length will be changed, whether ½ of the embedding pattern can be embedded is determined.
