  • Patent number: 9521649
    Abstract: In a system in which an in-vehicle apparatus and a smartphone are connected to each other, screen display switching cannot be performed with priorities of all the applications taken into account as respective terminals carry applications. A management block is provided in an in-vehicle apparatus or in a smartphone. The management block holds priority definitions for starting and displaying applications on both terminals. In response to external input to both terminals, the management block selects the application to be started and displayed. The management block identifies the terminal carrying the selected application, and transmits to the identified terminal a request to start the application and to switch display output accordingly.

  • Patent number: 9515829
    Abstract: [Objective] When installing software into an in-vehicle terminal from a server, it is required to prevent the software from being installed into an unsuitable terminal, and to reduce time and efforts for data input and download, thereby improving the convenience of the user. [Solution] In an information distribution system, terminal identification information and a terminal unique key for an in-vehicle terminal are stored in a server as well as in itself. The in-vehicle terminal transmits the terminal identification information to the server for terminal authentication via a communication terminal after encrypting with the terminal unique key, and then the server transmits encrypted software to the communication terminal. The communication terminal transmits the encrypted software to the in-vehicle terminal, which in turn obtains a software unique key encrypted with the terminal unique key from the server and decrypts the encrypted software for installation using the software unique key.

  • Patent number: 8832183
    Abstract: In a client processing apparatus, each application program independently performs communication with a server processing apparatus in spite of relevance between the application programs. For example, when plural application programs issue a request at the same timing in correspondence with a user's operation, the operation speed of the application program may become low. A request which occurs at the same timing of a particular request outputted from an application program to the server processing apparatus is previously defined in a communication grouping table. When the application program actually outputs a request, the communication grouping table is referred to, then the request and a request in the table to occur at the same timing are transmitted at once to the server processing apparatus. The server processing apparatus processes the plural requests at once, and returns the result of processing to the client processing apparatus.
