摘要:
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. 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.

A retrieval tree data storing unit configured to store node information corresponding to the relationship between information configuring data to be retrieved and information of a lower layer configuring the data rather than the information and retrieval tree data corresponding to entity identification information for identifying entity data representing an entity of the data to be retrieved which is specified by the information or the lower information included in the node information; an input controlling unit configured to output a candidate of the data to be retrieved based on the information or the lower information inputted by a user and the node information stored in the retrieval tree data unit; and an entity data acquiring unit configured to transmit to the retrieval server device a retrieval request including the entity identification information corresponding to the information or the lower information included in the candidate of the data to be retrieved.

摘要:
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.
