Definitions
- the present invention relates to a system for using a computer as a server for televisions.
- a terminal In business, it is possible to work with a remote office application on a server without having a computer, thanks to a terminal called "thin client". It is a box with a minimum of components: a processor, limited RAM, possibly low-capacity storage memory and a network interface.
- This terminal does not have any ancillary elements such as hard disk, multimedia equipment and reader floppy disks or CD-Rom, but is equipped with ports for parallel or USB type terminals allowing the connection of a screen of a keyboard or a printer.
- a common digital decoder connected to a TV can be compared to a "thin client", but to date, there is no way to control a computer from a decoder.
- the device according to the present invention aims to remedy this state of affairs. It consists in using the resources of a computer for common decoder / television systems, capable of receiving large amounts of information without being able to store it or use it for multiple applications.
- the computer is seen as a resource server, all the decoders / televisions in the house are seen as a set of "thin clients” interacting with the server which offers them its resources.
- It consists of a module connecting to the decoder by a digital type link and comprising a microelectronic component with advanced filtering and an interface allowing the computer resources to be controlled from the decoder thanks to specific software embedded in the latter.
- This installation comprises a digital decoder 1 connected to a television set 2, a computer 3 and a module 4 playing the role of interface between the decoder and the computer.
- the module 4 which comprises a microelectronic component 5 ensuring the link functions, is connected to the digital decoder 1 preferably by means of an interface 6 of the "PCMIA” type (system used especially on portable computers for adding memory or a modem) or, alternatively, integrated into the decoder.
- the module is also connected to the computer 3 by an appropriate digital link 7 ("1394", "USB”, “DVB-CI” or "PCMCIA” module with output to the computer, wireless link).
- the digital decoder 1 is provided with a tuner 8 connected to the network 9 data broadcaster, a microprocessor 10, as well as an electronic assembly 11 comprising in particular the management module 12 of the decoder and an implanted software 13 specific to the application.
- the decoder 1 is in data reception mode, the data received being routed to the computer 3 by the digital link 7, the data is stored on the hard disk of the computer.
- An application on the set-top box 1 / television set 3 makes it possible to switch from a conventional reception mode to a terminal emulation mode allowing access to the previously stored data, but also to a set of functionalities offered by the computer 3 (for example the computer modem and software allow you to write, send and consult e-mail from the television 2, or a menu on the decoder 1 allowing you to connect to Internet sites or to launch various games downloaded previously at broadband on the computer, etc.).
- a set of functionalities offered by the computer 3 for example the computer modem and software allow you to write, send and consult e-mail from the television 2, or a menu on the decoder 1 allowing you to connect to Internet sites or to launch various games downloaded previously at broadband on the computer, etc.
- the more or less advanced remote control of the decoder 1 or of the television set 2 makes it possible to control access to these functionalities by means of specific software 13.
- Decoder 1 has a specific operating system capable of running software specific to this system: suitable applications are downloaded at high speed to the computer via the decoder. These applications are then available to the user of the decoder who can download them from the computer 3.
- the computer allows the decoder to access all of its resources and can, at the request of the decoder, run any application. Only the "image" of the execution is transmitted to the decoder.
- the commands of the remote user are entered on the decoder by means of a remote control and then routed to the computer which interprets them as commands for the software which it runs for the decoder.
- a protocol is defined allowing: - on the one hand to allow the decoder to interpret the "images" (or
- a / Multimedia teletext Periodically, all of the television programs and their description are transmitted at high speed and stored on the computer 3. Unlike conventional teletext, or even new Guide type applications. program (TPS, CanalSat ..), this "multimedia TV journal" contains in addition to the text, images of the programs to be broadcast, film extracts, animations and possibly advertisements. The storage capacity of the computer also makes it possible to store several different "logs", it behaves like a "kiosk” server. The user can then view his programs in a richer way from his television 2.
- b / The "digital jukebox" From a decoder application
- the user can decide to download digital music (as a set of files, or by routing the audio channel of a television channel to the computer 3).
- Application software installed on the computer allows you to replay the recorded songs and send them to the decoder.
- This application can offer a very rich interface thanks to the resources of the computer.
