Definitions
- the present invention relates, on the one hand, to methods of transmitting and displaying data and, on the other hand, to devices for implementing such methods.
- the document FR-A-2.648.299 proposes a method and devices for transmitting to subscribers connected to a high-speed digital telecommunications network, from a central server, information recorded in a collection of digital discs.
- a device according to the invention comprises a central server connected by an interface to a digital telecommunication network to which subscriber stations are connected.
- the server center comprises a central computer, a digital disc store, optical disc player decks and means for transferring discs between the store and the player decks, in particular a conveyor and a handling device controlled by an automatic machine. - even controlled by the central computer.
- EP-A- 0.646.856 An information search device displays portions of a modifiable document dynamically requested by a user.
- the device has a controller connected to a display screen, input selection switches such as buttons, and memory such as a non-volatile flash memory.
- input selection switches such as buttons
- memory such as a non-volatile flash memory.
- a receiver such as a call device, a modem or FM radio receiver
- the device is turned on, a first portion of a document is displayed on the display screen.
- the user wishes to see another part of the document, or another document, he presses one of the buttons. Following the detection of the pressure on the button an action is performed and changes the display on the screen.
- the action carried out can vary in complexity: it can cause the display of the next page of the document, or can execute an internal hypertext link so that information contained in the same document, or another document, is updated on only part of the display screen.
- the document is stored in memory in a way that allows the display screen to be renewed directly from memory. When part of an updated document is received by the receiver, that part of the memory is updated.
- This patent describes the use of stacking or blocking of documents, then some stacks of the document are modified.
- the method according to the invention precisely wants to avoid this kind of problem.
- the present invention appears to be a judicious alternative for minimizing the quantities of information to be transferred while retaining the advantage of having the most recent information.
- This system leads to an optimization of the speed of information display for the end user, on the one hand, by a significant saving of the time necessary for a program to decide on the choice of the acquisition of new data or the use existing data, and on the other hand, loading new data only when necessary.
- the present invention relates to two methods and two devices for implementing these methods which are costly. very low operating, and whose installation is easy, and which are of a better level of security.
- the server includes some modifiable data which can be transmitted to each station, at the request of the subscriber concerned, so that a display is possible at the level of said subscriber's station, on the one hand, of the information carried by the disc and, on the other hand, from the transmitted data.
- the invention relates to a method for transmitting and displaying regularly updated data from a central server and intended for at least one subscriber station, via a digital communication network, where each subscriber who wishes to know the updated data, connects his station to the server, characterized in that the server ensures the automatic transmission of digital data to said station where software allows:
- the invention relates to a method for regularly transmitting and displaying data updates from a central server and intended for at least one subscriber station, via a digital communication network, where each subscriber who wishes to know the updated data, connects his station to the server, characterized in what the server ensures the automatic transmission of digital data to said station where software allows to simultaneously display the transmitted data and information from the reading of a digital disc, floppy disk or other associated with the station of the subscriber.
- a file called "index" is used. At the start, the data is recorded on a magnetic, optical or magneto-optical medium.
- New data, on a remote server is regularly updated by the publisher of the media content.
- the remote server contains a file called "index", containing information relating to the version of the computer media compatible with the data made available on the server, the name and location of the files available, and their characteristics (date and size in bytes).
- index a file containing information relating to the version of the computer media compatible with the data made available on the server, the name and location of the files available, and their characteristics (date and size in bytes).
- This one containing only the minimum information is therefore downloaded very quickly. From then on, the program will compare the information contained in this "index" file and the information on the files present locally on the user's computer storage medium (s). If it appears that the file present on the server is more recent than the local file or that the local file has been modified, the program then performs an update of the file by downloading the one present on the server.
- the fineness of the update depends on how often the "index" file is loaded. This can be triggered automatically according to a calendar, a deadline or at the user's request.
- This technique is particularly advantageous in the context of updates with known periodicity, much greater than the time necessary for a complete transfer of files from the server to the user.
- the method according to the invention allows the editor of the initial program to decide for himself which files to update and at what moment .
- the server "index" file is automatically generated during the connection of a user by a program present on the server.
- the "index” file also includes the date of the next modification of the files present on the server.
- the information is recorded on the same medium as that containing the initial application (rewritable CD).
- the invention also relates to a device allowing the implementation of the method, according to the first mode of operation, which is characterized in that it comprises:
- each station consisting, on the one hand, of a system for storing an indexed file comprising data already transmitted by said server and recorded and, on the other hand, of a comparison system of an indexed file containing the data available on the server and the indexed file containing the recorded or stored data in order to keep the stored data, if there are no modifications in the transmitted indexed files, or d '' download and replace stored data by the data available at the level of the files indexed on said server, transmitted if there have been modifications,
- the invention also relates to a device allowing the implementation of the method, according to the second operating mode, which is characterized in that it comprises:
- - a digital communication network for the transfer of data from the server to at least one subscriber station, - at least one subscriber station,
- the communication network used is the telephone network.
- the subscriber station is a personal computer
- the reader and the digital disc are constituted by a compact optical disc with laser reading
- the display means is a screen.
- the digital disc includes non-modifiable information, some of the spaces provided for this purpose are blank, on the other hand, the stored data is intended to be placed at the level of these spaces during display.
- FIG. 1 represents a schematic view of the device according to a first embodiment of the invention, to allow the implementation of the first mode of operation of the method.
- FIG. 2 represents a schematic view of the device according to a second embodiment of the invention, to allow the implementation of the second mode of operation of the method.
- the present invention relates to two methods of transmitting and displaying data as well as two devices allowing their implementation.
- the server 11 and the subscriber station 13 are connected to each other by communication network 12, which can also be constituted by a telephone network.
- the server 11 can be connected with a very large number of subscriber stations 13. To facilitate understanding, a single station 13 has been shown in the figures.
- Each station 13 consists of a reader 16 of digital discs, each digital disc comprising, on the one hand, information 17 and, on the other hand, free spaces 18 to allow the reception of the data coming from the server it.
- this system can be used by companies which manufacture, resell or have a distribution network. If these companies wish to make an electronic link available to resellers, the system according to the invention will be entirely suitable. It will ensure a commercial service, by allowing to maintain a permanent presence, which a commercial staff cannot provide. It also allows fast and reliable commands through its network, which contrasts with the old telephone contact techniques which require a switchboard and archiving of fax orders. In addition, this system also provides after-sales service by updating technical files and ordering parts in a simplified manner.
- the server 11 via the network 12 will transmit the data which is not present at the level of the digital disk. These can be values that are often editable, such as price, quantities in stock, or if the item is being promoted.
- the transmission and display method according to the invention will therefore make it possible, at the reseller screen, to have an up-to-date document, comprising, on the one hand, the information carried by the digital disc, which are fixed, and on the other hand, the data coming from the server 11, which are variable, but which will always be updated. It will follow from this that the connection time between the subscriber station 13 and the server will be minimized by transmitting only variable data. The cost will be very low, and the transmitted data not being linked with the information on the digital disc, they will necessarily be secure because incomprehensible to anyone who would come to know it, in the absence of the information on the compact disc.
- the embodiment of the device can be a little more complex to ensure an even more efficient service.
- the server 1 and the subscriber station can be a little more complex to ensure an even more efficient service.
- a data storage system 4 is added at the level of said station 3, on the one hand, a data storage system 4 and, on the other hand, a comparison system 5 of the stored data with respect to the transmitted data.
- the reseller at the station 3, will connect to server 1, via the digital communication network 2.
- Server 1 will then transmit the data concerning the files it has via the digital network 2 to the comparison system 5 of subscriber station 3
- the comparison system 5 At the level of this comparison system 5 the data previously received are already stored. If the data for the files available on the server and the data for the stored files are identical, there is no change in the data stored. On the other hand, if the data received shows a change from the stored data, the new data will be downloaded and replace the old stored data. This storage takes place at system level 4.
- each station 3 consists of a digital disc player 6, each digital disc comprising, on the one hand, information 7 and, on the other hand, free spaces 8 to allow reception of the data from server 1.
- Such a system can make it possible to enhance products and services, retain multi-brand resellers, motivate reseller networks, update all variable data very quickly, manage stocks as quickly as possible, to have rapid feedback, and finally to minimize telephone sales and after-sales services.
- the technical objectives are the simplicity of implementation of the server and of the client systems, the control and the ease of updating the data, the cross-platform client compatibility, and the management of unlimited simultaneous connections.
- the financial objective is to minimize the costs of telecommunications, server implementation and server related training and maintenance.
- the weight of information will therefore be 240,000 bytes, or 234.3 KB. Under these conditions and in the case of a current configuration allowing a link at 2 KB per second, the time to transfer for all of the information will be very brief, of the order of 100 seconds, and the number of articles updated very large.
