- the request manager 51 is connected to the input ports 121 to 121 and centralize the first RQP requests sent by the first peripherals 21 to 21.
- Each request received on a predetermined input port is assigned a network session identifier IS , such as a session number, assigned by the manager 51.
- the manager 51 thus permanently scans the input ports 121 to 121 to detect the first requests there.
- the manager 51 and the interpreter 53 keep in memory an image or current page of the latest information displayed in each second peripheral 31 to 31 and restored by the interpreter 53 so as to be able to correctly interpret a user action under the form of a reference to one of the buttons 211 to 214 in each first device.
- the manager 51 converts each first RQP request designating a server or a file in a server into a second RQL or RQD request transmitted in the telecommunications line LT to the designated server, for example which is the local server 6 in the equipment 1 or the remote server SD connected to the telecommunications network RT.
- the manager 51 considers the number of the input port having received an RQP request as an IS session identifier according to the TCP or UDP transport protocol and introduces into the RQL or RQD request the address of the server designated in the RQP request as as destination address and port number IS input port that received the RQP request in the application source port (socket).
- the manager 51 verifies that access to the designated server is authorized for the first device which issued the RQP request.
- the access rights of a pair of peripherals can be different from those of other pairs of peripherals so that each pair of peripherals respectively access respective local applications in the server 6 and respective remote applications in at least the remote server SD.
- a pair of peripherals 21-31 dedicated to parents is authorized to access local applications in the server 6 such as consulting an electronic mailbox, while another pair of peripherals 22-32 dedicated to parents. children is not authorized to access the electronic mailbox but can access playful applications in predetermined remote servers for example.
- the correspondence table 52 stores the correspondences between the session identifiers IS and the NPS output port numbers designated in first RQP requests.
- the content of table 52 evolves as a function of connection or disconnection. peripherals to the ports of equipment 1 and depending on the availability of sessions on the RT network.
- the correspondence table is constantly updated by the request manager 51 and consulted by the interpreter 53.
- Each RSL, RSD response contains in the destination port the IS network session identifier corresponding to the source port in the second RQL, RQD request received by the corresponding server. 6, SD in order to read the NPS output port number (s) in the correspondence table 52 corresponding to the received session identifier IS.
- the interpreter temporarily stops the transmission of data messages as soon as it no longer receives a DTR activation message, which means that a small page has been transmitted.
- These interpretation and splitting of RSL, RSD responses into data messages are adapted to the rendering capacities of the second peripheral (s) connected to the corresponding output ports whose numbers have been found in the correspondence table 52.
- the interpreter then controls the switch ports 54 so that the data thus formatted are routed to the corresponding second peripheral (s).
- the manager 51 associates by default the output port, for example port 131 of the second peripheral 31 which is linked to the first peripheral 21, to the input port 121 according to the example in which the RQP request is detected without an output port number, as indicated in a first line of the table 52.
- the manager 51 establishes a dynamic correspondence in table 52 by writing the session number IS relating to the input port, for example 122, which received the RQP request in correspondence with the designated output port or ports, as indicated in a line intermediate of the table 52, so that the interpreter 53 broadcasts small pages of RSP response to the second peripherals connected to the designated output ports.
- the request manager 51 in the browser manages several RQP input requests transmitted simultaneously by different first peripherals 21 to 23 and therefore a priori used by different users.
- the correspondence table 52 is consulted simultaneously by the interpreter 53 to convert second RSL and RSD responses transmitted respectively by the local server 6 and the remote server SD into first RSP responses to the second peripherals 31 to 31 through the port switch 54 and the output ports 131 to 131.
- the management of the first RQP requests and therefore of the first "keyboard" type devices 21 to 21 by the manager 51 is independent of the management of the first RSP responses and therefore second peripherals 31 to 31 of the "display" type by the interpreter 53.
- FIG. 6 shows the simultaneity of the management of two requests RQP1 and RQP2 transmitted by the peripherals 21 and 22 following the solicitation of determined buttons, for example respectively the validation button to validate the transmission of a document from the remote SD server to the peripherals selected 31 and 33 and the button to return to the previous page.
- the manager 51 opens a session with the remote server SD designated in the RQPl request, matches the session identifier 121 to the output ports 131 and 133 in the table 52 and transmits a request to the SD server HTTP RQDl.
- the manager In response to the RQP2 request, the manager opens a session with the local server 6 designated in the RQP2 request, assigns by default to the session identifier 122 the output port 132 and transmits to the server 6 an HTTP RQL2 request.
- the local server 6 retransmits an RSL2 response containing the previous hypertext page which is converted into at least one RSP2 response and routed by default to the peripheral 32 by the interpreter 53 and the switch 54.
- the interpreter 53 broadcasts at least one RSP response to one or more second predetermined peripherals 31 to 33 independently of the reception of a specific RQP request by the request manager 51 sent by one of the first peripherals linked to the second predetermined peripherals, that is to say independently of any voluntary user action on the first peripherals 21 to 21.
- the correspondence table 32 has previously stored the correspondence between a predetermined session identifier IDP and the output port numbers 131, 132 and 133 connected to the second predetermined peripherals 31, 32 and 33, as indicated on a last line in table 52.
- the predetermined session identifier IDP (socket) is reserved for broadcasting data to predetermined devices.
- the identifier IDP identifies in at least one server, such as the server 6, SD, a destination port linked to a predetermined application and introduced into a determined response RSL, RSD of the server.
- the determined response contains for example an advertising banner or personal information, such as the deposit of a message in an electronic mailbox.
- the server 6, SD transmits this determined response to the interpreter 53 for example when the equipment 1 is put into operation and after a protocol exchange between the server 6, SD and the browser 5, or else after the opening of one of predetermined sessions with the server by the browser, that is to say in particular when launching one of the predetermined applications.
- the interpreter 53 in the browser 5 takes the initiative in broadcasting the determined response RSL, RSD in the form of one or more small pages of RSP response to the second predetermined peripherals 31, 32 and 33. Following the determined response received RSL, RSD, prior to the broadcast of any small RSP page, the interpreter 53 transmits a predetermined message or control character (step P7; FIG. 5) to the protocol automats 216 in the second peripherals predetermined connected to the ports of designated outputs in order to make them switch from the button request waiting state (step P4, FIG. 5) to the line message reception state (step PI, FIG. 5).
- the correspondence table 52 is configurable statically or dynamically to correspond an input port, called session identifier, to one or more output ports, depending on whether the correspondence was introduced by an RQP request or was preprogrammed in the browser. Thus an RQP request can be restored to any second device.
- the local server 6 hosts a home portal. WML pages making up the home portal are stored locally in a mass memory 7 which can be a hard disk or a non-volatile memory of the EEPROM or Flash EEPROM type for example.
- the server 6 reads home application pages in the memory 7 via a link 67 under the control of the RQL queries of the browser 5 and returns RSL responses which are interpreted and routed by the browser 5 respectively to the peripherals 31 to 31.
- the memory 7 not only contains WML pages organized in a tree structure as well as other local data such as for example configuration files in order to choose a home page associated with a playback device 31 to 31, historical files , account identifiers such as internet access accounts and email accounts, HTML pages, MP3 audio files, local electronic mailbox (email), calendar, etc.
- HTML pages in the memory 7 are used to configure a WML home page by choosing a subset of headings from a pre-established list.
- the local server 6 may also decide to give access to specific information such as news, 'the stock market, sports scores, transportation schedules, etc. in external sites through the RT network.
- the local HTTP server 6 transmits parameters to executable programs, for example scripts or executable CGI (Co my Gateway Interface) in an interaction manager 8 which returns a WML page to the server 6 via a link 68.
- the interaction manager 8 allows a CGI program, by implementing relatively simple functions, to retrieve parameters by means of an RQL HTTP request associating a URL address designating the program with a GET method or POST, which is transmitted to it by the HTTP server 6.
- the manager 8 provides a WML page or more generally data encapsulated in a RSL response of the HTTP protocol.
- a variant of the invention provides for translating HTML pages into WML pages outside of the central equipment 1 so that the pairs of peripherals access formats of much more data.
- the adaptation of the content is carried out by a PR-SC translation means in the RT network which, in response to a specific request, will seek information and adapt the content thereof in order to respond to the client in a suitable format.
- the translation means comprises a PR format conversion proxy and a content server SC as shown in FIG. 7.
- One of the first peripherals 21 issues an RQP request for a determined document that the browser '5 or the server 6 is not capable of rendering directly, for example "http://www.actualite.fr/article.html” .
- the browser 5 or the server 6 transmits to the proxy PR a request containing a reference to the determined document, but the format of which is not adapted to the rendering capabilities of the associated device 31, for example "ADAPT http: //www.actualite .com / article.html ".
- the PR proxy extracts the URL address of the request and issues a request relating to the document in question to the content server SC: "GET http://www.actualite.fr/article.html".
- the content server returns the determined document by inserting it in a " ⁇ !
- the PR proxy adapts the format of the response according to the translation rules, in this case HTML to WML, which it has.
- the proxy response to device 1 is " ⁇ ! DOCTYPE wml ...> ⁇ WML>".
- Browser 5 or server 6 interprets and renders the document to device 31.
- CGI executable programs read and write to local memory 7, in particular WML pages and configuration files which are ASCII text files and which can be read and / or modified by CGI executable programs via a link 78.
- Executable programs CGI are also capable of sending and receiving requests and responses, in particular HTTP and POP, exchanged with remote SD servers via a link 81 with the LT line.
- the CGI programs also launch, via a link 89, the execution of non-CGI executable programs in a software module 9 which notably includes a player of sound sources 92 for reproducing sound for example from a selected radio program station connected to the RT network, via a sound adaptation card 91 and the link manager 4 to a second device 3C of Hi-Fi system type.
- the Hi-Fi device 3C is conventionally remotely controlled by wire, infrared or radio by another second device 3T of the chain remote control type which receives commands which are included in RSP responses from the interpreter 53 through the switch 54 and the link manager 4, following HTTP RSL responses transmitted by the interaction manager 8 via the local server 6 when one of the peripherals 21 to 21 has selected and transmitted a command in an RQP request.
- the non-CGI executable programs in module 9 are applications that differ from CGI programs in that they do not generate no output WML file and cannot be called directly from the HTTP 6 server, but can be called indirectly by a CGI executable program.
- an audio file player 92 in the module 9 is called by a CGI driver 86 in the manager 8, via the link 89, in order to read an MP3 file in the memory 7 via a link 79 or to connect the equipment. central to a radio station station site broadcast over the internet.
- the manager 8 includes the executable programs
- the following CGIs a POP client 82, a home page builder 83, a home page choice modifier 84, a file system tree explorer 85, an audio file player driver 86, and a driver of high-fidelity chain 87.
- the POP client 82 is used to query a POP email account associated with a remote mail server SD and generates a WML page indicating the number of messages for a user being on the mail server queried using links 81 and 78. For each message, the WML page contains fields such as the sender, the date, the subject and the size of the message.
- the client 82 formulates a WML response page in accordance with the CGI mechanism and introduces all this information therein so that the server 6 sends it in the form of an RSL response to the user's device 31, after interpretation in the browser 5 following a second RQL request sent by the browser at the request of the first device 21.
- a WML home page broken down into small RSP display pages by the interpreter 53 is obtained according to one of the three methods for a pair of given peripherals 21-31.
- the home page constructor 83 sends in a second RSL response an HTML form read in the memory 7 which is in the form of RSP responses transmitted to the given peripheral 31 following a request to construct RQP home page by the device 21.
- the user validates responses in the form received, for example of the checkbox type, which are chained and returned via the browser 5 and the server 6 so that the constructor 83 build a home page based on chained responses.
- a WML home page can be replaced at any time by a page selected by the user and recently received by the given device 31, by returning the URL address of this page by the browser under the command of the device given 21 to the home page choice modifier 84 which is used to configure the home page selected for a pair of devices 21-31 according to the URL address.
- the WML page then generated is the selected home page.
- the browser 5 uses the modifier 84 when it recognizes a keyword
- the modifier 84 receives via the server 6 as a parameter in an HTTP GET request, the selected address URL of the new home page and the number of the input port IS of the first given device 21.
- the modifier 84 writes to a file memory configuration 7 this association between the URL address and the input port number so that the next browsing session relating to the given peripherals 21-31 begins with said new home page.
- the configuration file is read locally by browser 5, although it can also download it.
- the modifier 84 then opens the WML file corresponding to the new home page to transmit the content as an RSL response.
- a WML home page is selectively replaced by the user, by any page constituting a file found during navigation in the tree structure of a local file system, in particular of configuration in memory 7, using the file system explorer 85.
- the explorer reads the list of files present in a current directory and generates a WML page whose links are associated with directories or files and allow respectively to recursively navigate to a "child" directory or else to modify the choice of a home page via the modifier 84.
- the CGI explorer 84 receives via the server as a parameter an HTTP GET request containing a node of the file system tree, that is to say the name of a directory.
- the explorer 85 reads the contents of this directory by "primitive" functions of the operating system and thus establishes a list of directories and files which is filtered in a filter to eliminate symbolic links and data of no interest to it. 'user; this filter is also present in the configuration file.
- the explorer returns a WML page containing this list of the second given device of the user via the browser 5.
- Each entry in the list is a link whose validation by the user causes the emission of an RQP request then of an HTTP RQL request with a URL address containing the name of the file or directory to explorer 85.
- the link is a directory
- the new page, as an RSL response returned by the explorer is the content of this directory , in accordance with the mechanism described above; a particular symbol, for example "..”, makes it possible to go up in the tree structure to the first node of the file system.
- the link is a file name, the link includes the word- key which is contained in the corresponding RQP and RQL queries and which makes it possible to establish this file as a home page.
- the audio file player driver 86 is used to control the audio file player software 92 in the module 9 so as to reproduce sound by local sound sources in the central equipment 1.
- the driver 86 takes as parameter the reference on an audio file or a URL address designating the audio stream from an internet radio station, or command instructions such as play, pause, etc.
- the CGI driver 86 generates in a second RSL response a WML page giving for example the state of the audio player and references on possible sound source commands to a pair of predetermined requesting peripherals 22-32.
- the player driver 86 recovers the name of the audio file reader in a memory configuration file 7 and recovers from an RQL request sent at the request of the first requesting device 22 an identifier of the audio file to be played and searches in a second configuration file for the file corresponding to this identifier.
- the driver 86 knows the name of the audio file player and the identifier of the audio file, it starts the player 92 passing it the name of the audio file as a parameter.
- Certain identifiers of audio files are specific and correspond to codes which cause the pilot 86 to launch an instruction to the player to influence the behavior of the player according to commands received for example to increase or decrease, the volume or stop the music or select a radio station.
- the driver 86 returns a WML page to the second requesting device 32 in the form of an RSL response to the browser 5.
- This WML page contains the name of the file played by the player and links to driver 86 to change the behavior of player 92.
- the high-fidelity chain driver 87 generates, following an RQP request from the first requesting device 22 via the browser 5 and the server 6, a WML page presenting all the possible commands on the Hi-Fi system, such as volume control, compact disc player control, radio tuner control, tape recorder control, etc.
- the control page is transmitted in RSL responses to the second device 32.
- Each elementary function of the 3C Hi-Fi system is encoded by a control character that the chain is able to recognize.
- the string driver 87 extracts from an HTTP GET request transmitted by the browser 5 corresponding to an RQP request from the first device 22, the command character of the elementary function chosen in the device 32.
- the command character is retransmitted in a response HTTP RSL to browser 5 which interprets it in an RSP command response intended via port 13T for the remote control device 3T which controls the function chosen in the Hi-Fi system 3C.
- the user equipped with the pair of peripherals 22-32 and located for example in his kitchen to choose for example a radio station program or a local sound file, which can possibly come from a remote site or from memory 7 via sound card 91, and which is reproduced by the 3C chain located in another room, such as the living room.
- the pilot 87 signals to the pair of peripherals by a WML page transmitted to the browser 5 that the GET request with the chosen command character has been taken into account.
- the use of the chain driver 87 illustrates a situation where one of the second peripherals of the central equipment has no screen and nevertheless renders a WML page.
- the equipment can also be used in a public place.
- a museum provides a couple of peripherals to each visitor to allow him to consult cultural databases through the equipment.
- a visitor equipped with a pair of inventive peripherals can consult local information on exhibitors in a trade fair by interrogating the equipment, or can consult transport schedules or advertising or other local information, by querying equipment installed at an airport or station.
