Definitions
- the present invention relates to a multi-function digital satellite terminal.
- Patent No. WO 01 58 133 describes a multifunctional home audiovisual system comprising a decoder box, the front or bottom of which has several open bays intended to accommodate peripherals and which may include an integrated computer module.
- the decoder, the computer and the peripherals communicate with each other via a high speed bus.
- Peripherals are primarily hard drives, CD-ROMs and DVDs, modems, satellite receivers, TV tuners, interface modules for video games, MIDI modules, and modules designed for connection to various equipment audio and video.
- the price of this box, intended in particular to be integrated into a TV cabinet, is, because of its equipment of the same order of magnitude as that of a computer and its use requires the same knowledge.
- FR 02 16 895 established by the applicant of this document, describes a method consisting in using a satellite-type radio channel to broadcast the messages to be transmitted to all the digital satellite receivers used for reception. television channels, the reception of messages being carried out directly on digital receivers arranged to allow viewing of messages received on the television when the satellite receiver is switched on or at the request of the user.
- This process allows the reception on a television set of messages of the "e-mail" type broadcast by satellites. It does not require a telephone or computer connection to receive messages and the warning of receipt of a message is sent directly to the television without the need to connect to the Internet.
- the system according to the present invention aims to make the basic functions of a personal computer ("PC") available at low cost.
- PC personal computer
- USB Universal Serial Bus
- FIG. 1 is a diagram illustrating the principle of the system.
- the system uses a television 1 intended for connection to a digital terminal 2, itself connected to an antenna 3 pointed at a satellite 4.
- the digital terminal 2 is equipped with a "USB” port and simple office application software capable of fulfilling the basic functions of a personal computer ("PC") and in particular the functions "printing”, “word processing”, “faxing”, “photocopying”, “digital photo reader” and "video games”.
- PC personal computer
- USB Universal Sériai Bus
- This interface allows a wide variety of peripherals to be connected without restarting the computer, with better bandwidth (and therefore higher transfer speed) than serial or parallel ports.
- I “USB” has many advantages: no risk of plugging the plug upside down (it does not fit), or breaking a pin (there is none) , and especially no need to add an additional controller card to each new device.
- the "printing" function of the digital terminal 2 makes it possible, among other things, to print the electronic mail ("e-mails") received by the terminal using a specific module that performs decryption and storage of messages, as well as address management using to integrated software, these messages being transmitted via a transmitting station 5 by a server 6 capable of receiving the messages sent by the senders (cf. patent N ° FR 02 16 895).
- the "word processing" function associated with the "printing" function, advantageously replaces a typewriter.
- the "fax” (or “fax”) function will be associated with a modem connected to the USB port or inserted in the PCMIA reader and allowing the terminal to be connected to a telecommunications line.
- the "video games” and “digital photo player” functions are similar to those existing on other digital terminals.
- the "word processing" function requires the use of a printer 8 connected to the USB port of terminal 2 and a keyboard with infrared or radio transmission, radio transmission requiring the addition of a radio receiver in the terminal, while infrared transmission does not require addition since it uses the infrared channel of the remote control.
- the "photocopy” function also requires the use of a scanner 9 connected to the USB port.
- the device managers of the devices connected to the USB port, as well as the application software are either integrated into the terminal, or downloaded from a smart card 10 or the Conditional Access Module (M.A.C.) of the digital terminal 2.
- M.A.C. Conditional Access Module
- the system according to the invention can be adapted for the transmission of secure data with double encryption by adding a secure transmission procedure applying in particular to the consultation of a bank account statement, the printer 8 making it possible to archive the statements.
- the operator provides his client with a numbered smart card, the card's access code and a numbered access module. If the customer already has a module, he must simply communicate the serial number. The customer inserts the module in the digital terminal 2 which must be connected to an antenna 3 pointed at a satellite 4 broadcasting the required data.
- the access module is arranged to automatically record the data addressed only to this module during the standby of the terminal or after selection of the broadcast transponder by the user. These recorded data are accessible only on this module when the smart card is inserted in the module and when the user has typed the access code specific to this card which was communicated to him when the card was handed over.
- the data is first coded by the operator using public cryptography (RSA) and / or digital software.
- RSA public cryptography
- the unique decryption key is recorded during production in each smart card and cannot be changed.
- Each serial number corresponds to a unique encryption key known only to the operator.
- This encrypted data is encrypted a second time using an encryption system compatible with the DVB standard. This second key to unique decryption is recorded during manufacturing in each module and cannot be modified.
- Each serial number corresponds to a unique encryption key known only to the operator.
- the module therefore decodes the second encryption and the smart card the first.
