Information transmission system, transmitter, and transmission method as well as information reception system, receiver and reception method

Content data encrypted with a content key, the content key encrypted with an individual key specific to an information sending device, and the individual key encrypted with a distribution key that is updated in a predetermined cycle, and supplied are sent to an information receiving device, and the information receiving device decrypts the individual key with the distribution key, decrypts the content key with the individual key, and decrypts the content data with the content key. Thus, the information sending device does not have the distribution key, and accordingly piracy of content data can be prevented with a simple configuration. Also, the information receiving device sends the content key and a playback command to other apparatuses. Thus, other apparatuses can play back contents using the playback command and the content key. Furthermore, the information sending device decrypts the content key with the distribution key before being updated, and stores the same. Thus, contents purchased by an advance order can be actually purchased regardless of expiration dates of the distribution key. Furthermore, usage right is passed from a first information receiving device to a second information receiving device different in registration information at the tome of using contents. Thus, contents can be used among information receiving devices different from each other in registration information.

Method, device and system for adjusting driving modes and vehicle

The invention discloses a method, a device and a system for adjusting driving modes and a vehicle. The method includes receiving a voice instruction; querying feature databases; determining parameter information of the driving modes on the basis of to-be-confirmed voiceprint features; acquiring the voice instruction and acquiring the parameter information of the driving modes in driving procedures. The method, the device, the system and the vehicle have the advantages that the vehicle can be adjusted to be in the most familiar and habitual driving modes by the aid of the single voice instruction, and accordingly users can be positioned in habitual driving environments without manually adjusting the parameter information of the driving modes; the parameter information of the driving modes of the users can be automatically acquired in the vehicle driving procedures of the users without being manually set by the users, the tedious properties of user operation can be prevented, specific physical buttons can be omitted, and influence on the aesthetics of internal environments of the vehicle can be prevented; the quantity of the parameter information of the driving modes of the users is unlimited for the same vehicle, and the personalized driving modes of the various users can be implemented.

An electrically heated smoking system comprising at least two units

There is provided an electrically heated smoking system comprising a secondary unit capable of receiving a smoking article having an aerosol-forming substrate. The secondary unit comprises at least one heating element and an interface for connection to a primary power supply. The secondary unit further comprises a secondary power supply and secondary circuitry.; The secondary circuitry is arranged to control supply of electrical power from the secondary power supply to the at least one heating element in a pre-heating mode during which the temperature of the aerosol-forming substrate is increased to an operating temperature, to control supply of electrical power from the secondary power supply to the at least one heating element in a smoking mode, during which the temperature of the aerosol-forming substrate is maintained at substantially the operating temperature, and to control charging of the secondary power supply by the primary power supply, in a charging mode,; so that the secondary power supply has sufficient charge to increase the temperature of the aerosol-forming substrate to the operating temperature in the pre-heating mode and to maintain the temperature of the aerosol-forming substrate at substantially the operating temperature during the smoking mode. The electrically heated smoking system may optionally include a primary unit comprising the primary power supply and primary circuitry. By dividing the power supply between the primary unit and the secondary unit, the secondary unit can be made smaller and more convenient for the user.
