摘要： When many buses are provided, addition/omission of a bus frequently occurs. Whenever the addition/omission of the bus occurs, a configuration process of the overall network system must be performed. Thus, interruption of data communication occurs frequently. Second bridges are provided that are bridges each having a function of performing a configuration process for assigning individual identification numbers to a lower network. The second bridges are used to connect buses to one another.

摘要： An image transmission method, image anti-duplication method, image anti-duplication device, and image recording medium in which information for anti-duplication control is superimposed on a video signal without deterioration of the resultant video signal and the information is extracted accurately and quickly to perform anti-duplication control. An output device starts generation of pseudo-noise (PN) corresponding to a PN code start timing signal generated based on a video sync signal. One chip interval of the PN code is divided into a plurality of divided chips corresponding to a PN code inversion timing signal HT, and an original value of a chip is inverted on an alternate one divided interval to generate a PN inversion code. An anti-duplication control signal is subjected to spectral spreading using the PN inversion code and superimposed on the video signal. In the recording device which receives the video signal from the output device, inversion spectral spreading is performed based on the PN inversion code generated in the same way as that generated in the output device.

摘要： When an information signal recorded in a magnetic card is updated by an information recording and updating apparatus, a spectrum spread signal corresponding to the updated information signal is generated and it is then recorded superimposed on to the information recorded previously in the magnetic card without erasing the old information. Since the information is spectrum spread, alteration is difficult. Moreover, the magnetic card may be discriminated whether it may be used or not by considering the old information recorded in the magnetic card when it is used.

摘要： A mobile radio station radio-communicates with a base station in accordance with a code division multiple access scheme to receive an information provision service from an information service center through the base station. The information service center supplies information data for information service, type data indicating the type of information data, and update data including version data of the information data to the base station. The mobile radio station receives the update data transmitted from the base station and displays the type data on a display, when the desired selected type data is selected from the displayed type data by user's operation, if it is judged that the corresponding information data is the latest information data based on the version data corresponding to the selected type data, receives the information data.

摘要： A playback device 10 generates a PN code with a start timing based on a video sync signal, and generates a pseudo random noise (PN) inverse code which has a reverse polarity to that of the PN code with a timing based on the video sync signal. An anti-duplication control signal is spectrally spread using this PN code, superimposed on the video signal and supplied to a recording device. A PN inverse code which is the same as the PN inverse code used in the playback device is also generated in the recording device based on the video sync signal, and reverse spectral spread is performed using this PN inverse code.
