Definitions
- the present invention relates to a method for providing access to a large number of users to a collection of digital multimedia documents.
- Digital multimedia document is understood to mean any document digitized in the form of a computer file which may be of the videos, graphic animations, photos, sounds, music, texts, electronic games or any composition of these multimedia elements and in particular any type of site.
- the access generally offered to select digital multimedia documents on demand, and in particular to video documents or to Internet sites, is traditionally carried out by a so-called “point-to-point” device.
- These accesses then require a high speed computer link between each access terminal and the computer server center which has, in stored memory, multimedia documents in digital format.
- These computer links must allow transfer speeds of 300,000 (three hundred thousand) characters per second minimum for access to television quality video documents.
- These links can be terrestrial such as cable, satellites, or even wireless.
- many computer links are required as there are terminals. According to this scheme and in the context of a device for accessing multimedia documents on demand for the general public, as many high-speed computer links are required as there are access terminals to allow the simultaneous transfer of these files. bulky digital.
- the cost of a broadband computer link is very high and such a configuration supposes a multiplication of this cost by the number of terminals thus making this type of access to demand system financially far too high to date to be actually deployed.
- the multimedia document server should then send simultaneously a number of files at least equal to the number of connected terminals. Which as part of a consumer project could exceed one hundred thousand terminals. No current computer server can guarantee the flow necessary emission which should then be greater than thirty billion characters per second.
- the object of the present invention is to propose a method for giving access to a large number of users to a collection of digital multimedia documents, and this from a single server center and without multiplication of computer links.
- the collection of digital multimedia documents is transmitted by satellite over a given geographical area. Its reception takes place simultaneously using reception terminals by all the users present in this given geographical area.
- the digital multimedia documents received by the terminals are stored, preferably according to a profile of interest of the user, in a storage unit associated with each terminal. Subsequent access to a stored document will normally require a digital access authorization file which is transmitted to the user after requesting access to the document.
- Figure 1 illustrates the mechanism of a first step of a method according to the invention. This step corresponds to the sending of documents to dedicated reception terminals 8.
- Multimedia documents to be made accessible to the dedicated terminals are stored in a server center 1 in the form of computer files.
- These files are sent to a computer device for satellite transmission of digital data 3 via a high speed terrestrial computer network link 2.
- the files are therefore coded and sent in the form from an electromagnetic wave to a satellite 10 which returns it 5 over a given geographical area.
- This operation can concern several files sent simultaneously with priority levels making it possible to predefine the transfer speeds to be allocated to the sending of each file.
- All of the satellite reception terminals 8 present in the geographic area covered by the satellite 10 simultaneously receive, via a parabolic antenna 6 dedicated to satellite reception, the wave 5 transmitted. This antenna 6 is connected to the terminal via a coaxial computer link 7.
- the satellite decoding device present in the terminal 8 decodes the electromagnetic wave 5 to recreate the computer files initially coded.
- the users can personalize the profile of the digital multimedia documents which must actually be stored in the storage unit 9 of the terminal 8.
- the files reconstituted according to the principle stated above and corresponding to the profile defined by the user are effectively stored in the storage unit 9 of the terminal 8.
- the files not corresponding to this profile are erased as and when they are received by the terminal 8.
- the stored files are automatically erased progressively according to their age in order to free up space for storing new received files. It will however be appreciated that the user has the possibility of marking stored files as non-erasable.
- Figures 2a, 2b and 2c illustrate the mechanism of a second step of a method according to the invention.
- This step corresponds to the order and access to multimedia documents stored in the terminal.
- Figure 2-a illustrates the mechanism making it possible to reach a file stored in the storage unit of the terminal 8.
- the user can seek one or more of these documents by using for example a remote control 12, a keyboard or a mouse computers connected to the reception terminal 8.
- the list and the details of the documents stored in the storage unit of the terminal 8 are displayed on the monitor 14 connected to the terminal 8.
- This monitor 14 can be either a traditional television set or a monitor computer science.
- the terminal 8 connects to the server center 1 via a remote computer link 16, which can for example be a telephone link.
- the terminal 8 after being identified by the server center 1 sends its request for access rights to the desired multimedia document in the form of a digital file.
- the server center 1 can then process the access request received.
- the user 18 telephones a dedicated telephone server 20, by a traditional telephone line 22.
- the user 18 then dials, using his conventional telephone handset, his identification number followed the number of the document he wants to access.
- the user 18 can log off, his command is taken into account.
- This command which is materialized by a digital file, is then sent by the telephone server 20, via a computer link 24, to the server center 1 of digital multimedia documents.
- the server center can then process the received access request.
- FIGs 3a and 3b illustrate the mechanism of a third step of a method according to the invention, namely the reception of access rights to multimedia documents stored in the terminal.
- the server center 1 of multimedia documents generates an authorization as a digital file.
- This file is sent to the computer system for satellite transmission of digital data 3 via the high-speed terrestrial computer network link 2.
- the file is therefore coded and sent in the form of an electromagnetic wave 4 to the satellite 10 which returns it to the geographic area it covers.
- the satellite reception terminal 8 of the user at the origin of the command receives this wave 5 via its parabolic antenna 6. Only the satellite decoding device present in the terminal 8 decodes the electromagnetic wave 5 to recreate the file corresponding to the access authorization in response to the command made by the user.
- the file corresponding to the authorization allows the terminal 8 to display or play the digital multimedia document, already stored in the storage unit 9 of the terminal 8 and which has is the subject of a command issued by the user.
- the multimedia document is then displayed on the monitor 14 and / or played by the sound reproduction device.
