A first acquisition unit of a control device mounted on a vehicle acquires first traveling information at least including position information on a host vehicle. A second acquisition unit acquires second traveling information at least including traveling track information on a vehicle ahead when braking occurs in the vehicle ahead. A determination unit determines a threshold value based on the second traveling information acquired by the second acquisition unit and the first traveling information acquired by the first acquisition unit. An output unit gives a notification of braking in the vehicle ahead in accordance with a relationship between a distance and the threshold value determined by the determination unit, the distance being defined between the traveling track information in the second traveling information acquired by the second acquisition unit and the position information in the first traveling information acquired by the first acquisition unit.

Control method and control device for controlling notification

A first terminal device is disclosed that is mountable in a first vehicle. The first terminal device comprises: an acquirer that acquires first information on the first vehicle; a receiver that receives a packet signal from a second terminal device, the packet signal including second information on a second vehicle in which the second terminal device is mounted; a controller that selects a first plurality of driving supports that are capable of being provided to a driver of the first vehicle among a second plurality of driving supports, based on the first information and the second information; and a display that displays each of images representing each of the first plurality of the driving supports in more detail as priority given to each of the first plurality of the driving supports is higher.

Terminal device

A first communication unit receives packet signals broadcast from a base station apparatus and also receives packet signals broadcast from other terminal apparatuses according to a first communication scheme. A second communication unit communicates with a mobile apparatus according to a second communication scheme that differs from the first communication scheme. A receiving unit receives a filtering condition from the mobile apparatus by way of the second communication unit. A filtering unit selects a packet signal, which matches the filtering condition, from among the packet signals received by the first communication unit. A transfer unit transfers information, contained in the selected packet signal selected, from the second communication unit to the mobile apparatus.

Terminal apparatus for transferring signal containing predetermined information and communication system

A memory card () includes a memory () to store encrypted content data, a license hold unit () to store at least a portion of license information distributed by a distribution system, a plurality of authentication data hold units (), each storing a plurality of authentication data that are authenticated respectively by a plurality of public authentication keys KPma, KPmb common to the distribution system, and a switch (SW) to selectively provide the data from the plurality of authentication data hold units outside of said recording apparatus according to a request external to the memory card ().

Content data storage

A home server according to the present invention transmits a screen information including a second apparatus identification information identifying a second apparatus and which correlates with a first apparatus identification information identifying a first apparatus, and operation contents realized through linkage of the first apparatus and the second apparatus.

Home server

A memory card () conducts an authentication process with a server based on data stored in an authentication data hold unit (). The memory card () extracts a first session key (Ks) from a server by a decryption process and a transaction ID from the data applied on a data bus (BS). The memory card () generates a second session key (Ks) through a session key generation unit (), and transmits to the server, as the keys to encrypt content data in receiving decryption of content data, the second session key (Ks) and a key (KPm()) unique to the memory card () in an encrypted state with the first session key (Ks). The transaction ID and the second session key (Ks) stored in the log memory () are used in the redistribution process.

Memory card and data distribution system using it

A license server () includes a CRL database () holding a revocation list recording therein classes predetermined corresponding respectively to a memory device, such as a memory card, and a content reproduction circuit, such as a cellular phone, that are subjected to revocation of distributing, reproducing and transferring content data. A distribution control unit () suspends an operation distributing content data if the distribution is addressed to a class listed on the revocation list. The revocation list is also held in the memory card and distribution control unit () in distributing content also transmits information for updating the revocation list in the memory card.

Data distribution system and recording device and data provision device used therefor

An object of the present invention is to realize an in-home network system that is capable of smoothly controlling an appliance even when a new kind of appliance that has not been obtained conventionally is connected to an in-home network or even when an unusual, special use form is set in a network. A controller of the present invention compares a device type of an appliance connected to an in-home network with a skeleton stored in a skeleton DB. When a skeleton rule in accordance with the appliance type is not stored in the skeleton DB, a request for acquisition of the skeleton rule of the appliance is transmitted to a service agent. In addition, when the location of an appliance is moved, the controller sends a request for transmission of a new rule format to be added due to the movement to the service agent.

Controller, program product, and storage medium

A cellular phone () stores encrypted content data and encrypted license key distributed thereto in a memory card (). The cellular phone () and the memory card () collectively perform a part of mutual authentication processing upon power-on. The encrypted license key (Kc) read from the memory card () is decrypted by a first decryption processing portion () with a session key (Ks), and is further decrypted by a second decryption processing portion () with a system symmetric key (Kcom) for extraction. A third encryption processing portion () decrypts the encrypted content data read from memory card () with the license key (Kc) to reproduce content data (Data).
