Definitions
- the present invention relates to a router device for the flow of 5 digital data.
- Reception of digital programs or services requires a decoder generally in the form of a box connected to a television set or possibly a computer card.
- the 5 decoder is the part of the receiver which allows the interpretation and the presentation of the data and not that which allows their decryption - or decryption -, this second part, called "access control", is sometimes completely assimilated to the decoder by language abuse.
- the installations and materials existing to date, whether it is a digital television with decoder, a video recorder or a 0 digital recorder decoder, allow simultaneous access to only one program, namely for recording, or for viewing.
- the device aims to remedy this state of affairs. It makes it possible to record an encrypted channel or not on a computer (storage area) and to watch on the computer or television a recorded channel by decrypting it if necessary. For a reasonable cost, it gives the possibility, using a single access control, to choose between three data sources: two external sources (tuners) and one internal source (storage on computer) and three outputs: two external outputs ( computer screen and TV) 0 and an internal output (storage area). It allows you to watch a program on a television while other information is recorded and can be viewed later, possibly being multiplexed with a program watched live (without being synchronous with the television stream).
- It consists of a box equipped with a tuner connected to a satellite antenna or to a data broadcasting network, a packet demultiplexer for the reception of digital data, means making it possible to connect it to a digital decoder and to a computer as well as a "router" block making it possible to interconnect all the digital stream inputs or outputs, from and to the digital decoder, from and to the computer, and from the tuner.
- FIG. 1 is the block diagram of an installation allowing the application of the proposed system.
- This installation comprises a digital decoder 1 connected to a television 2, a computer 3 and a box 4 "flow router" constituting the invention proper.
- the digital decoder 1 is provided with an interface 5 supporting the digital stream ("1394" type or other digital link) and with a tuner 6 connected to a satellite antenna 7 or a data broadcasting network.
- the box 4 "flow router” has an interface 5 'allowing it to be connected to the digital decoder 1 and a means of connection with a computer 3, which may consist of a wireless link. It is equipped with a 6 'tuner connected to a 7' satellite antenna or to a data broadcasting network, and a packet demultiplexer for the reception of digital data (possibly MPEG satellite stream). All digital stream inputs or outputs, from and to the digital decoder 1, from and to the computer 3, and from the tuner 6 'are interconnected by a block of the housing 4, the "router" block 9.
- the router block 9 can be controlled by one or more means such as a control panel on the housing 4 itself (buttons, possibly a liquid crystal screen), telecom- command or software residing in computer 3 (therefore remotely controlled if the protocol connecting the computer to the box is a wireless protocol).
- the “router block” 9 makes it possible to route at least two independent data streams so as to be able to record or view a stream on the computer while watching a decoded program on the television 2, or to use the digital decoder 1 to view a stream received by the tuner 6 'from the box 4 while the stream received on the tuner 6 from the decoder is routed to the computer via the "router" box. It also allows you to use the decoder to view a stream previously recorded on the computer.
- the box 4 can be equipped with a chip card reader 10 which can be controlled by an access control 11 on board the box 4 to decrypt a stream received on the tuner of the decoder 1 and reinjected either on the decoder itself either to computer 3 to view or record.
- a chip card reader 10 which can be controlled by an access control 11 on board the box 4 to decrypt a stream received on the tuner of the decoder 1 and reinjected either on the decoder itself either to computer 3 to view or record.
- the access control 11 makes it possible to decrypt an encrypted stream recorded on the computer 3, then routed from the computer to the decoder or to the screen of the computer itself (in this case the stream leaves the encrypted from the computer, is decrypted in the box "router" 4 and reinjected in clear towards the computer),
- the access control 11 also makes it possible to decrypt a stream received on the tuner 6 'of the box 4 and to view either on the television set 2, either on the computer 3 (for example if the stream is a video program, the MPEG2 decoder of the digital decoder 1 can be used after a decryption in the box 4, and if the stream corresponds to data such as encrypted Internet pages , they are rather redirected to the computer 3 after passage through the access control 11.
- the smart card reader 10 can also be controlled by access control software 8 on board the computer 3 or in the decoder digital 1. In this case the comms andes smart cards can use the box-decoder or box-computer links to allow software to communicate with the smart card.
- the tuners 6, 6 'and the antennas 7, 7' will be adapted to the chosen reception mode (Hertzian, Satellite, Cable, etc.).
