摘要： A traffic management system manages, distributes, and controls various traveling states of vehicles at a high quality level. A vehicle-mounted unit performs an interconnection process for user authentication when entering a predetermined radio-wave zone. A radio unit disposed on a road sends interconnection process completion information to a center device when the interconnection process for connection to the vehicle is completed. If the vehicle does not connect to the radio unit after elapsed of a predicted time at which the vehicle is expected to travel across the radio unit, then the radio unit sends an overtime to the center device. The interconnection process completion information is received, the center device calculates a predicted time at which the vehicle is expected to pass across a radio unit, and sends the predicted time to the radio unit. When the overtime is received, the center device determines whether a fault has occurred or not. When it is judged that the fault has occurred, the center device sends alarm information to vehicles traveling near a site where the fault has occurred on the vehicle.

摘要： A digital signature program includes computer-executable instructions for giving a numerical value in a state where header information necessary for playback of each partial data item may be added to the partial data item resulting from the division to a one-way function to generate an output value sequence of the one-way function concerning the multiple partial data items. The program also includes computer-executable instructions for generating binary trees concerning the streaming data, having leaves including only the output values in the output value sequence; and computer-executable instructions for using an output value indicating a root of the generated binary trees to generate a digital signature of a signer for the streaming data.

摘要： A data sending system which prevents a parity error occurrence in a data receiving unit is provided. The data sending system provided is related to data sending systems and, particularly, to a data sending system where plurality of data sending units share a path for data transmission. The data sending system provided comprises a network consisting of a data path and control path, a control unit for instructing data sending through said control path, one or plural data sending units for sending, according to an instruction from said control path, data to a specific one of plural logical paths of said data path, and a data receiving unit permanently connected to the one of plural logical paths of said data path. Said control unit has a determining section which determines a time span, during which no sending data exists in a logical path connected to said data receiving unit, and also instructs a specific unit of said data sending units to send dummy data during the time span. Said data sending unit has a dummy data sending unit which sends the dummy data, to which an appropriate parity information is added, according to said instruction.

摘要： A coding apparatus is for performing a deblocking filter process by dividing input moving image data into frames, and coding the moving image data by dividing the frames into macroblock lines and by shifting and changing, for each frame, a refresh area in which an amount of coding information allocated to a specific macroblock line is larger than that of another macroblock line. The coding apparatus includes a determining unit that determines that a refresh area in a current frame as well as a macroblock line in the current frame corresponding to a macroblock line that will become a refresh area in a frame being subsequently subjected to the coding process becomes a next refresh area. The coding apparatus includes a coding unit that codes the refresh area and the next refresh area by allocating a larger amount of coding information than an amount allocated to the other macroblock line.
