  • Patent number: 6487543
    Abstract: Information associated with broadcasting, information associated with a network, and information associated with a package are included in data. A terminal device has means for acquiring data from broadcasting, data from the network, and data from the package. The terminal device further has a means for displaying the data acquired by the above-mentioned means together or a means for displaying information included in the data as a link. This novel constitution allows positive information provision to users by a combination of three types of media, broadcasting, network, and package. At the same time, this novel constitution allows provision of new services by making the most of mass storage provided by package and up-to-date information provided over network.

  • Patent number: 5630135
    Abstract: A method for executing programs in a distributed processing system includes executing in a plurality of first processors different programs which perform the same function. Messages, containing data representing execution result output from said different programs and attribute information indicating function to be performed by the different programs, are transmitted from the first processors to a network. A second processor then receives these messages and selects a message therefrom based on an analysis of the attribute information contained in all of the received messages. The second processor then executes an application program using the data contained in the selected message. Alternatively, the message-selecting step is made based on both the attribute information and data contained in the messages received in the second processor. Each of the messages from the first processors may include graphic image data which can be analyzed and shown on a display.

  • Patent number: 5594872
    Abstract: In an information processing system having plural processing units connected through a communication medium, each processing unit operates to receive information to be transmitted from a processing portion operating in the processing unit to the communication medium and a content code predetermined according to the content of the information to be transmitted. Based on the received content code, the processing unit operates to determine an address of the destination processing unit, a sending mode used for transmitting the information, and whether or not the more reliable communication method arranged to establish a connection between the processing units is used for transmitting the information. Then, by using the sending mode and the communication method obtained as the determined result, the information is transmitted to the processing unit having an address obtained as the result determined through the communication medium.

  • Patent number: 5333265
    Abstract: A replicated data processing method and apparatus for a distributed processing system are provided in which a plurality of processors are connected to one another through a common transmission line. The processors perform processes using replicated data produced by resources such as files replicated in respective processors. Any processor issues an access request and broadcasts the request to the common transmission line. User's program of the processor is initiated by a first-received data in response to the request, and checks matching between the first-received data of the replicated data and the subsequently received data to repeat a retry processing for the request until a mismatch is removed.
