Description

! "Data transmission method in a network, server on a

  network implementing such a method, method of producing such a server, arrangement on an image monitor of a page of such a server "The present invention relates to a method of transmitting data in a network, a server on a network implementing such a method, a method of producing such a server, and an arrangement on a

image monitor from such a server.

  Many servers are known on networks, particularly on the Internet, which offer users the possibility of consulting an illustrated catalog. An inconvenience for the user stems from the fact that this catalog is generally inconvenient to use. The consultation of such a catalog requires waiting for the site search, the connection to the site, the loading of many pages, long to load due, on the one hand, to the volume of the catalog especially if it contains images and , on the other hand, the limited bandwidth offered by the network: in addition, to move from one page to another, the user is obliged to wait, each time, for the site search, the connection to the site and data loading. This is all the more tedious the larger the catalog and / or the user

has a lot of data to look for.

  The object of the invention is to remedy these inconveniences by proposing, according to a first aspect, a judicious method of transmitting

  data allowing the user to access the data more quickly.

  Such a method can be used to transmit catalog pages while reducing the data waiting time. According to a second aspect, the invention proposes a server using such a transmission method. According to a third aspect, the invention proposes an ingenious method for producing such a server. According to a fourth aspect, the invention renders the pages of a

  inherently more convenient catalog to use.

  More specifically, the invention relates to a method of transmission-

  transfer of data from a first transmission device to a second transmission device, said second transmission device being adapted to store the data transmitted to it, said second transmission device comprising a data presentation device for said data transmitted, said transmitted data being adapted to be transferred to the data presentation device to be brought to the perception of a user of the second transmission device, comprising at least one operation of transmitting, to the second transmission device, so-called primary data and so-called secondary data, characterized in that only the primary data transmitted is transferred to the data presentation device while the secondary data transmitted is stored in the second transmission device without being transferred to the p riphérique

data presentation.

  The first transmission device is generally called the server device, or more simply the server and the second transmission device is generally called the user device or more simply

user or client.

  It is observed here that the word "data" used in this document is used in a general sense: it designates instructions, information, documents, calculation results, images, photos, texts or / and

programs.

  The term "data transfer" designates the fact of supplying - data from a device to a peripheral which comprises said device. The data can also be or remain stored in said

device.

  The term "transmission" of data refers to the fact of supplying data from a first transmission device to a second transmission device, without generally specifying whether or not this data is transferred to a peripheral of said second transmission device. The data can also be or remain stored in said first transmission device. According to the invention, the secondary data transmitted and not transferred are immediately available when the user wishes to consult them: there is then no need to search for the address of the first transmission device, connect to it and bring the data back to the second transmission device since it already has it. Advantageously for this method, the primary data is then transmitted to the second transmission device, then the secondary data. The first transmission device sends the primary data first and then the secondary data: either it sends the secondary data immediately after the primary data: by doing so the transmission time is the shortest, or it sends the secondary data when the transmission of the primary data to the second transmission device is finished: by doing so, the primary data are available before the secondary data in the second transmission device and can then be used immediately by the user. Preferably, for this method, the primary data transmitted is first transferred to the data presentation device, then the secondary data is transmitted to the second transmission device. The second transmission device first sends the primary data to the data presentation device, then the first transmission device sends the secondary data to the second transmission device: either the first transmission device sends the secondary data immediately after the second device has sent the primary data: by doing so the transmission time is the shortest, or the first transmission device sends the secondary data when the transfer of the primary data to the data presentation device is complete. Advantageously, for this method, so-called secondary data being stored in the second transmission device without being transferred to the data presentation device, said secondary data are transferred to the data presentation device and so-called tertiary data are transmitted to the second communication device. transmission, said tertiary data being, after transmission, stored in the second transmission device without being transferred to the peripheral

presentation of data.

  Thus, it is thus judiciously, by the method of the invention, to transfer the secondary data to the data presentation device and to transmit the tertiary data to the second transmission device. Advantageously, for this method, the secondary data are first transferred to the data presentation device, then

  transmits, to the second transmission device, the tertiary data.

  This takes place analogously to the transfer of primary data and

  the transmission of secondary data.

  Preferably, for this method, it is the user who controls the transfer of the secondary data to the presentation device of

data.

  This is how the user, when he orders the transfer of secondary data to the data presentation device, obtains

said data immediately.

  Advantageously, for this method, the first transmission device being a server, the second transmission device being a user transmission device comprising a network navigation means, it is implemented by the server in cooperation with said

  user transmission device.

  Navigation means, or more simply a browser, navigation software (such a browser is called "browser" in English). Judicieusemeht, it is the server which implements the process of

I r--

  The invention, in fact a programmer can implement at the server level the method of the invention for the specificity of the server and of the application

that he offers.

  According to a second aspect, the invention relates to a server characterized in that it implements a method as presented above.

  The invention is particularly well suited to a server.

  According to a third aspect, the invention relates to a method of producing a server as presented above, the server comprising catalog pages, characterized in that said catalog pages are automatically generated from a database. data and we memorize

  said catalog pages in the server.

  One indicates under the term of "catalog" a whole of pages

  intended to be supplied to a user and containing data.

  This process also makes it possible in particular to reduce the duration

users waiting.

  According to a fourth aspect, the invention relates to an arrangement of images on a monitor, characterized in that, said images being data conveyed by a method as presented above, said monitor being the data presentation device, said images being transferred to said monitor, there is at least one horizontal line on the

  monitor who encounters several images.

  Thus, we transmit a lot of information per page.

  Other characteristics and advantages of the invention will emerge

  moreover from the description below, with reference to the accompanying drawings on

  which: FIG. 1a is, according to the prior art, a simulation of the use of data from a catalog available on a server, by a user, representing the ordinate O if the user is waiting for data and , Ordinate U if the data are available to the user, as a function of the time represented on the abscissa, FIG. 1b represents, for the same simulation as in FIG. 1a, the search for the server comprising the data from the catalog, the connection to this server and the loading of data by representing the ordinate R if a search, a connection or by loading is in progress and, by representing the ordinate 0 otherwise, FIG. 2a (respectively 2b) is analogous to the figure la (respectively 1 b) for this catalog, the data being transmitted by a method according to the present invention, FIG. 3 represents a device for transmitting data from the catalog illustrated on the Internet: this is the serv eur comprising the illustrated catalog data, intended to be transmitted to a consultation door of a user, FIG. 4 represents a device for transmitting data on the network, it is a consultation station intended for a user of the catalog, FIG. 5 is a representation of an example of data transmission according to a method of the present invention between the devices of FIG. 3 and of FIG. 4, and FIG. 6 is an embodiment according to the present invention of a

  catalog page layout on an image monitor.

  An embodiment of the present invention will be described below. In Figure 3, there is shown a device for transmitting an illustrated catalog on the Internet; this server device is represented in the form of a block diagram under general reference 10. It comprises, interconnected by an address and data bus 102: - a central processing unit 106, - a random access memory RAM 104, - a memory dead ROM 105, an input and output port 103, and

  - a 110 connection to the Internet.

  Each of the elements illustrated in FIG. 3 is well known to those skilled in the art of information processing systems, transmission systems, data processing and networks. These elements do not

are therefore not described here.

  It is observed here that the word "register" used below designates, in each of the memories, both a low-capacity memory area, retaining only a few binary data, and a memory area of

  large capacity, allowing to store an entire program.

  The main memory 104 stores data in registers of

  brief bearing, in the following description, the same names as the

  data whose values they keep. The random access memory 104 comprises, for the sake of clarity, a catalog of four pages, noted respectively on page 1, page 2, page 3 and page 4, more precisely: registers "graph1", "graph2", "graph3" and "graph4": the register "graph1" (respectively "graph2", "graph3" and "graph4") contains the graphic data of page 1 (respectively of page 2, of page 3 and of page 4), - registers "text1", "text2", "text3" and "text4": the register "text1" (respectively "text2", "text3" and "text4") contains the data in the form of text from page 1 ( respectively from page 2, from page 3 and from page 4), - a "display" register (respectively "display2", "display3" and "display4") which contains a program which is part of page 1 (respectively pIage 2, page 3 and page 4), the operation of which will be described below and which can be executed by a browser, and - registers "research2", "research3" and "research4": the register "research2" (respectively "research3" and "research4") contains a program which is part of page 2 (respectively 3 and 4),

  which is executable by the browser and whose operation will be described below

after.

  The random access memory 104 constitutes a means of storage

  information readable by a computer or microprocessor.

  According to a variant, the random access memory 104 is removable, partially or totally, and comprises, for example a magnetic tape, a floppy disk or a compact disk with frozen memory ("CD-

ROM "in English).

  ROM 105 stores data in registers

  from memory bearing, in the following description, the same names as the

  data whose values they keep. The read-only memory 105 comprises in particular the operating program of the central processing unit

  processing 106, in a "program 1" register.

  In Figure 4, there is shown a data transmission device on the Internet, here is a user device that is to say a consultation station for a user. This user device is illustrated under general reference 20 and is illustrated in the form of a block diagram. It comprises, linked together by an address and data bus 202 - a central processing unit 206, - a random access memory RAM 204, - a ROM read-only memory 205, - an input and output port 203, a modem 208 connected to an Internet access provider 209 called "provider" or "Internet access provider" in English which provides a connection 210 to the Internet, - a display screen 207, also called monitor, connected to the input port and outlet 203, and

  - a keyboard 201 connected to the input and output port 203.

  Each of the elements illustrated in FIG. 4 is well known to those skilled in the art of information processing systems, transmission systems, data processing and networks. These elements do not

are therefore not described here.

  - r The RAM 204 stores data, variables and intermediate processing results in memory registers

  bearing, in the following description, the same names as the data

  whose values they keep. The random access memory 204 comprises in particular: a browser which is a software allowing access to the Internet servers and to seek the data there, and - a sufficient memory space to create there during the process described below: * registers "Ugraphl", "Ugraph2", "Ugraph3" and "Ugraph4": the register "Ugraphl" (respectively "Ugraph2", "Ugraph3" and "Ugraph4") is intended to contain the graphic data of page 1 (respectively page 2, page 3 and page 4), that is to say the register "graph1" (respectively "graph2", "graph3" and "graph4"), * registers "Utextl", " Utext2 "," Utext3 "and" Utext4 ": the register" Utextl "(respectively" Utext2 "," Utext3 "and" Utext4 ") is intended to contain the data in the form of text from page 1 (respectively from page 2 , from page 3 and from page 4), that is to say the register "text 1" (respectively "text2", "text3" and "text4"), * registers "Uaffichagel", "Ua Affichage2" , "Uaffiche3" and "Uaffichag e4 ": the register" Uaffichagel "(respectively" Ua Affichage2 "," Uaoulez3 "and" Ua Affichage4 ") is intended to contain a program namely" displaying "(respectively" posting2 "," posting3 "and" posting4 ") which is executable via the browser, * registers "Urecherche2", "Urecherche3" and "Urecherche4": the register "Urecherche2" (respectively "Urecherche3" and "Urecherche4") is intended to contain a program namely "recherche2" (respectively "recherche3" and "recherche4") which can be executed by the browser, and * a "page display state" register containing "display state2", "display state3" and "display state4" registers: the register "display2 state" (respectively "display3 state" and "display4 state") contains a boolean taking the value "yes" or "no" for

  give an instruction to the browser as will be described below.

  Read-only memory 205 stores data in registers

  from memory bearing, in the following description, the same names as the

  data whose values they keep. The read-only memory 205 comprises in particular the operating program of the central processing unit

  processing 206, in a "program 2" register.

  Read-only memory 205 constitutes a means of storage

  information readable by a computer or microprocessor.

  According to a variant, the read-only memory 205 is removable, partially or totally, and comprises, for example, a strip

  magnetic, a floppy disk or a compact disk with frozen memory ("CD-

ROM "in English).

  We will now describe how transmission takes place.

  data transfer between the server device 10 and the user device 20. The central processing units 106 and 206 are adapted to

  implement the flowchart described in Figure 5.

  A user wishes to consult the catalog available on the

server device 10.

  In FIG. 5, during an initialization operation not

  shown, a user commands the search for data on page 1.

  stored in the random access memory 104 of the server device 10. The browser

  send this command to server device 10.

  The server device 10 will implement a response method: it gives the browser the instruction to create (during an operation 511) the registers "Ugraphl", "Utextl", "Uaffichagel" and "Urecherche2" in the random access memory 204, to store therein respectively the contents of the registers "graph", "text1", "display" and "search2" transmitted from the server device to the user device and to execute (during an operation 512) the "display" program. By instruction of I n = = 17, I It programs "display", the browser transfers that is to say displays (during an operation 513) the contents of the registers "Ugraphl" and "Utextl" at the display screen 207, creates (during an operation 514) the "page display state" register in the RAM 204 and executes (during an operation 515) the "search2" program. Execution of the "search2" program instructs the browser to create (during an operation 516) a "page display state 2" register in the "page display state" register and 'initialize I "' display state of page 2" to "no" and search (during an operation 517) page 2 in the server device 10. (The content of the register "text1" displayed on the display screen 207 invites the user, after consulting the data displayed on page 1, to order page 2, by entering the key "2" on the keyboard 201: if the user enters "2", the content of the "page 2 display status" register

is modified and is then "yes").

  The server device 10 returns the response to the search for page 2: it gives the browser the instruction to create in the random access memory 204 (during an operation 521) the registers "Ugraph2", "Utext2", "Ua Display2 "and" Urecherche3 ", to store therein the contents of the registers" graph2 "," text2 "," display2 "and" search3 "and to execute (during an operation 522) the program" display2 ". Two scenarios are then possible: either the user has already entered "2" on his keyboard 201 and the "display state of page 2" contains the value "yes", then the program "display2" gives l instruction to the browser to display (during an operation 523a) the content of the registers "Ugraph2" and "Utext2" on the display screen 207 and to execute (during an operation 524a) the program " search3 ", or the user has not yet entered" 2 "on the keyboard 201 and the" display state of page 2 "contains the value" no ", then the program" display2 "gives the instruction the browser to wait for the user to give the instruction (during an operation 523u) to present the data to be displayed on page 2 by pressing the "2" key on his keyboard 201 to display (during 'an operation 523b) the contents of the registers "Ugraph2" and "Utext2" on the display screen 207 and then for

  execute (during an operation 524b) the program "research3".

  By this method, the browser begins to search for the server device 10, to connect to it and to search for the data on page 2 while the user consults the data displayed on page 1. This saves time by reducing waiting for the user when the latter wishes to consult page 2. In particular, if the data on page 2 is entirely transmitted from the RAM 104 of the server device 10 to the RAM 204 of the user device 20 when the user has finished consulting page 1, so when the user wishes to see page 2, it is transferred from the RAM 204 to the display screen 207 and this is immediate. The user has the data immediately

from page 2 he wants.

  The execution of the "research3" program is analogous to the execution of the "research2" program by incrementing by one, in what

  precedes, the index of the pages and the index which appears in the registers.

  The execution of the "search4" program is analogous to the "search2" program by incrementing by two units the index of the page as well as the index which appears in the registers and by deleting the phases which would appear and which would involve a program " search 5 "and registers" rechercheS "and" Urecherche5 "which do not exist because page 4

is the last page of the catalog.

  In a variant, the programs "search2", "search3" and search4 "form a single program, which takes as input the number of the page to be searched. This makes it possible to reduce the size of

  the memory used in the random access memory 204.

  Similarly, in a variant, the programs "display2", "display3" and display4 "form a single program, which takes as input the number of the page which is to be displayed. This makes it possible to reduce the

  size of the memory used in the random access memory 204.

  In a variant, the user has the possibility, when he consults page 1, of ordering page 3 and of consulting the latter without consulting page 2. Such a possibility can be indicated to him as soon as the data is displayed in the form of text on page 1 (that is to say as soon as "text1" is displayed) by offering to enter "3" on the keyboard 201 of his computer. The search for page 3 is then carried out by the browser by a method according to the prior art. In general, the user not only has the possibility of quickly accessing the next page from the one he consults, this page reaching him by a method according to the invention, but he also has the possibility of accessing to any page, that page reaching it by a

  conventional process well known to those skilled in the art and not described here.

  In FIGS. 1a and 1b, in the prior art is shown how an example of consulting the catalog takes place. At time t = 0, a person orders page 1 of the catalog available on a server on the Internet. Between time 0 and T, the person is on hold (ordered 0 in figure la) and the browser searches for the address, connects and loads, by transmitting it little by little, the data (ordered R in figure lb ). At time T the ordered page is brought back and displayed on the user's screen. Between time T and 2T, the user consults page 1 (ordered U in FIG. 1a) and no data command is in progress (ordered 0 in FIG. 1b). At time 2T, the user will order page 2 of the catalog and the process begins again. It appears, in FIG. 1a, that in order to consult the 4 pages of the catalog, the user puts a duration equal to 8T1 In FIGS. 2a and 2b, we have shown, with the invention, how the same example of use of the catalog. At time t = 0, a person orders page 1, available on the server. Between the instant O and T, the situation is the same as before. At time T, the page 1 ordered is brought back and displayed on the screen of the user. Between instant T and 2T, the user consults page 1 (ordered U in FIG. 1 b)

  and page 2 is automatically ordered (ordered R in Figure 2b).

  At time 2T, the user has finished consulting the first page and page 2 is in the random access memory 204 of the user's terminal. The user decides to consult page 2 and gives the instruction, the latter will be immediately presented to him and page 3 will be automatically ordered. Between time 2T and 3T, the same thing happens as between time T and 2T with page 1 replaced by page 2 and page 2

replaced by page 3.

  It appears in FIG. 2a that in order to consult the 4 pages of the catalog, the user puts, in this example of consultation, with the

  method of the invention, a duration equal to 5T (against 8T in the prior art).

  With the method of the invention, the user spends, in this consultation example, in order to consult the 4 pages, actually 80% of the time in consultation and only 20% pending (against only 50% of consultation time and 50 % waiting time in the prior art). It thus appears an advantage of saving time for the user, the latter can consult more pages and this in a more pleasant way. This advantage is all the greater as the number of successive pages consulted in the catalog is high and as the duration of provision of a page (namely the search for the server, the connection to it and the loading of the page ) East

  close to the duration of page consultation by the user. We have described above an embodiment of the method of

  transmission-transfer according to the present invention. It will be noted in particular here that, to implement the method of the invention, it is the server, in particular by the programs contained in its pages, which gives the instructions for transmitting the pages to the user device without

  transfer to said peripheral of said user device.

  There are many variants to carry out such a process without going out

of the scope of the present invention.

  In particular in an embodiment not shown, the method according to the invention can be implemented by producing the catalog as follows: the last page of the catalog contains data intended to be displayed on the user's monitor (they are called displayable data of this page and they are, unless otherwise instructed during transmission, immediately displayed when the data of the page is transmitted to the user device), each other page of the catalog contains, on the one hand, data displayable of this page (which are, unless otherwise instructed during transmission, immediately displayed when the data of the page is transmitted to the user device) and, on the other hand, a program (on the one hand, this program is initialized when the displayable data of the page in question are actually displayed and, on the other hand, this program instructs the browser to search for the data s on the next page with strict instructions to store them in the user's device without displaying the displayable data of said next page on the user's monitor). The browser is configured so that when a user controls a page, the browser first searches if the page is stored in the user device: if the page is stored in the user device, the browser immediately displays it , otherwise the browser searches for the ordered page in the server. When the user wishes to see a page and that he orders it, two scenarios are possible: either this page is in memory in a user device in which case, by the browser, the page is displayed and, if this page does not is not the last page, then, by the program it contains, the next page is transmitted to the user device without the displayable data of said next page being displayed on the user's monitor, or this page is not in memory in the user device in which case, by the browser, the page is sought and displayed and, if this page is not the last page, then, by the program that it contains, the next page is transmitted to the user device without the displayable data on the following page is not

  displayed on the monitor of the user device.

  Let us now consider a server comprising a catalog and using a transmission method according to the invention. This catalog includes 12 main pages numbered from 1 to 12. Each main page is linked to secondary pages of a first type and to

  secondary pages of a second type.

  FIG. 6 represents, for page 2 of the catalog, what appears on a monitor screen 2 using a browser. In the upper part of the monitor screen appears a control zone 4 in which are placed control zones, not shown, on which it is necessary to click with a mouse of the user device to control the execution of the functions offered. speak

Navigator.

  A useful area 1, allowing the presentation of the displayed data

  on page 2 is located below control area 4.

  The main page 2 (like all the other main pages except possibly the last) has 18 small photos (not shown) respectively arranged inside locations marked from 1 p to 1 8p. The small photos are each accompanied by a small comment (not explained) in the form of a line of text placed respectively inside spaces marked from 1 t to 1 8t: the small comment relating to the small photo in 1 p (respectively 2p to 18p) is arranged in 1 t (respectively 2t to 1 8t) just under the corresponding small photo, in addition the location 1 p (respectively 2p to 1 8p) is

  attached to the location 1It (respectively 2t to 1 8t).

  We chose to have six photos horizontally because, with the size of the screens of the monitors commonly used (screen size that we find commercially under the name "dimension 800 * 600"), we can easily present in a way nice 6 photos horizontally provided

  tighten them enough, as shown in Figure 6.

  Note that with a traditional browser available commercially or even for free use the useful area 1 is often substantially twice as wide as high, or the location 1 p (respectively 2p to 18p) adjoins location 1 t (respectively 2t to 18t) intended to present a small comment relating to the small photo 1p (respectively 2p to 1 8p) covers a very substantially square area: this is why, in our example, we have distributed the locations relating to small photos accompanied by small comments by arranging 6 such locations per line and 3 per column, that is to say twice as much per line than per column. The locations are arranged in a regular way, on the useful area 1 there is the same distance between the locations 1p and 2p of a

  part and the locations 1 t and 7p on the other hand.

  On a line, the space between two locations with small O10 photos (respectively small comments) is very small. If you draw in the useful area 1, a horizontal segment with a length equal to the width of the screen and passing through locations of small photos, then more

  percent in length of this segment meets such locations.

  This is an indicator that shows that there is a high concentration

  information per line on this screen.

  In a variant, it is possible to further increase the concentration of information per line: thus, the space between the locations 1 p and 2 p can be made very small, or even non-existent, either by increasing the size of the locations 1 p and 2 p, or by squeezing the locations of the same line

  to have more photo items per line.

  By squeezing small photos and small comments vertically in each column, we obtain a high concentration of information by column. In our example, we attached each small photo with the area of its small comment: thus, for example, there is no space between the location lp and the location 1 t and we vertically reconciled each small photo with the small comment of the small photo placed above: thus, for example, the location 7p is very close to the location I t (as a variant, the location 7p is glued to

location 1It).

  We thus obtain a very high concentration of photo by main page this allows easy use of the catalog, main page by main page indeed, by concentrating a maximum of information by main page, we reduce the number of main pages in the catalog: the consultation of the catalog is therefore easier and faster for a user because the latter has fewer main pages to browse to obtain the information he is looking for, he also has a more global vision of the catalog. In a variant, the ratio of the width to the height of the location lp is 3/2, this ratio is equal to the ratio between the width and the height of a conventional photo print arranged horizontally (dimension centimeters by 10 centimeters) : so we can directly arrange a horizontal photo in classic format at the l1p location, reducing it proportionally so that it covers the entire lp surface. this is

  also valid for pitches 2p to 1 8p.

  By arranging the information on a main page, so that for a monitor of usual size (screen size 800X600), we have all the information displayed (i.e. all the small images and all the small comments) simultaneously on the screen, then the consultation of the catalog is made easier because there is no need to move the screen of the page relative to the useful screen to consult all the information displayed on the page. Indeed, such a displacement is generally made, by command with the mouse, of a scale appearing on one of the sides of the screen (on the right or on the left of the screen for the vertical displacement of the information displayed on the main page in relation to the useful screen and at the top or bottom of the screen for horizontal movement of the information on the main page in relation to the useful screen) so if the user has a monitor of usual size, it can browse one main page after another, leaving its

  mouse stationary on the control area continued 7.

  In a variant, the successive main pages are joined together by being displayed on the screen, so that they no longer form a single page in which the user moves by means of '' a scale: in this variant, the user can browse all of all

  main pages transferred to the screen using the scale only.

  In a variant, the locations 1 t to 18 t can contain

  two or more comment lines.

  In a variant not shown, the locations 1It to 18t have larger dimensions in height in order to be able to have there more comments possibly on several lines. Each location can

  possibly be adapted according to the length of the comment.

  Command zones have been placed in the upper part of the main page: one of them, called return command zone 6 allows you to go to the previous main page and the other, called command zone continued 7 go to the next main page. The control zones 6 and 7 are placed very close to each other. Obviously the first main page has no return command area and the last main page has no continued command area. These control areas are very small so as not to occupy too much surface on the screen. They are circular, the return control zone engages at least partially in the spacing between location 2p and location 3p and the following control zone engages at least partially in the spacing between location 4p and the location p. Similar control zones 8 and 9 are also arranged

symmetrically at the bottom of the page.

  The close arrangement of the control zones 6 and 7 on the one hand, and of the control zones 8 and 9 on the other hand, allows the user to access the next or previous main page without having to move the mouse much , especially here without having to move the mouse too much

horizontally. -

  Similarly, the arrangement of similar control areas at the top and bottom of the screen allows the corresponding functions (which are the most common) to be used without having to move the mouse too much across the screen. A control zone 5 present on the useful zone 1 indicates on which main page of the catalog the user is located: in FIG. 6, the control zone indicates that the user is on page 2 of the 12 pages. By clicking on this zone, the user has the possibility of choosing any main page to which he wishes to access, by entering for example

the number of the page chosen.

  Thanks to hypertext links, the catalog is created in such a way that, if the user clicks with the mouse on the location It (respectively 2t to 18t) where a small comment is made concerning the small photo in lp (respectively 2p to 18p), then a secondary page of the first type is displayed on the screen with a large comment associated with the small comment (therefore also associated with the small photo). On the secondary page of the first type, the user is invited to return to the main page by clicking in a command zone. Preferably, this secondary page of the first type does not fill the entire useful area 1 of the screen and it is advantageously placed next to the corresponding small photo so that the user can simultaneously see the small

  photo and the big comment about the lot.

  If the user clicks with the mouse on the location lp (respectively 2p to 1 8p) where a small photo is arranged, then a secondary page of the second type is displayed on the screen having a large photo associated with the small photo. On the secondary page of the second type, the user is invited to return to the main page by clicking in a

control area.

  In a variant the secondary page of the second type contains the large comment in addition to the large photo: indeed the large photo takes longer to load than the large comment therefore we can

  also charge the latter in addition, without much difference in duration.

  The user has the possibility of browsing, from one end to the other, the different main pages of the catalog. In general, the user browses one main page after another. But he also has the possibility of directly accessing a main page which is not the next page of the main page he is consulting, by clicking with the mouse on the control zone 5, and entering the number on the keyboard. of the main page he wants to access. The user also has the possibility, by viewing a main page of the catalog, of consulting the large photo corresponding to a small photo by clicking on the corresponding area 1 p to 18 p, or of consulting the large comment linked to the small comment by clicking on the

zone 1t to 18t.

  For this catalog, a process for loading pages similar to that described in detail above is implemented. It appears

  several loading possibilities.

  A first way of proceeding consists, when the user orders a main page, of loading, not only this main page, but also the following main page so that it is

  immediately at his disposal if he requests it.

  A second way of proceeding consists, when the user orders a main page, of loading all the main pages of the catalog. A third way of proceeding, compatible with the previous ways of proceeding, consists, when the user orders a main page, of loading the secondary page of the first type linked by hypertext link to the location it and / or of the secondary page of the second type linked by hypertext link to location l p. A fourth way of proceeding, compatible with the preceding ones, consists, when the user orders a main page, of loading the secondary pages which meet a certain criterion of memory size (for example those which take the longest to load or those which

are the shortest to load).

  A fifth way of proceeding, compatible with the preceding ones, consists, when the user orders a main page, of loading all the secondary pages of the first type and / or all the secondary pages of the second type linked by hypertext links to the main page that the user orders. However, this procedure may be long, especially if the secondary pages of a type contain large photos, as is the case in our example where the secondary pages of the

  second type present precisely large photos.

  A sixth way of proceeding, compatible with the first, second, third and fourth way of proceeding, consists, when a user orders a secondary page, of loading the secondary page of the first type or / and the secondary page of the second next page type

  secondary controlled by the user.

  It all depends on the route that the user will take in the catalog. We can ask him which route he will perform in the catalog (that is, if he will essentially perform a course of the successive main pages, or if he intends to consult all the secondary pages, or all the secondary pages of a particular type ...), but we can also statistically study from the point of view of the server what is the average journey of a user to choose a loading process. This application is suitable for the presentation of a sales catalog which offers different articles or lots: the lot is represented on the small photo, and, the small comment is generally the designation of the lot, its

  brand, its creator to give the user a first idea of the lot.

  Then on the big photo, we present an enlargement of the photo or another view or several photos and on the big comment, we present all

  the written information that the user may wish.

  The invention is particularly well suited to the presentation of artists on an Internet server, by presenting a work in the small photo, the name in the small comment, the route in the large comment and an enlarged work in the large photo. In this case, we can have a catalog of ten, or even a few hundred to one

thousand main pages.

  The invention is also particularly well suited to the presentation of lots from an auction, by presenting a small photo of a lot, a keyword (for example, the designation of the lot, the brand, the name of the artist ...) in the small comment, the full description of the lot in the big comment and an enlarged photo of the lot in the big photo. In this case, we can have a catalog of a few pages

  main (from one to a few tens).

  Now consider a server with a set of auction catalogs. This server has a first page on which the sales calendar is displayed. From a sale in the sales calendar, the user can go to a page giving additional information on the sale. From the sales calendar, he can also consult the list of lots contained in a catalog as described above. He can also consult the list of lots presented in the form of a list of lots descriptions and access from the description of a lot either a detailed description, or a small photo of the lot with the

  detailed description, either to a large photo of the lot with the detailed description.

  For the list of lots presented in the form of a list of lot descriptions, we

  also provides a loading method according to the invention.

  The user also has the possibility to search either for a sale or for a subset of sales (for example future sales or past sales or week sales or month sales), lots of a certain artist, brand, or corresponding to a keyword. This search is performed on the server from a database. In written catalogs or in general in written books, the user could easily go from one page to another by leafing through the catalog. On a network, there is a loading time (server search, connection and transmission-transfer of data): by putting more information on each page, or even all the information on a page, we

  saves the user from having to wait for a load each time.

  Now consider how to store a catalog on a server. The pages supplied to a user can either be stored as such in the server's RAM and supplied as such to the user on request (this is the case of pages known to those skilled in the art under the term "HTML pages" "), or be constituted from a database according to the specific requests of the user by means of a program which takes as input the data of the users, which selects the relevant data from the database of data and / or performs operations and which thus constitutes a page supplied to the user (this is the case of pages produced from a script, for example a script known to those skilled in the art under the term of script

"CGI").

  In a preferred embodiment of a catalog on a server, we study which pages are the most frequently asked for and / or those which take the longest to calculate or / and those whose product of frequency request from a user by the

  page calculation time is the highest.

  We create these pages once and for all and store them as they are in the server's RAM. This makes it possible to avoid having the pages calculate each time by the server: in fact, such a calculation is long, and during this time, on the one hand, the user is forced to wait and, on the other hand, server availability for other users is

diminished.

  It will be noted that these pages can advantageously be constituted by a program, on a computing device (computer) other than the server and then provided to the server, for storing them there. This allows to leave

  totally the server available to users.

  In the event that modifications are made to the database, these pages are reconstituted taking into account the modifications in the database: the program calculates and thus provides the new modified pages as a function of modifications which have occurred in the database.

  and these new modified pages are stored in the server.

  In our example of a server presenting a set of auction catalogs, we constitute once and for all the pages presenting the sales calendar (of the week and of the month) from the data (places, times, etc.) of sales stored in a database. Catalog pages for each sale are also created in the same way, namely the page giving additional information on the sale, the catalog pages presenting the list of lots in the form of small photos and small comments, the page giving the list of lots presented in the form of a list of lot descriptions, the page giving the detailed description of a lot, the page presenting a small photo of the lot with the detailed description and the page giving a large photo of the lot with

the detailed description.

  In a preferred embodiment, the response pages to searches for lots in future or past sales are made up for

different artists.

  The invention thus combines, through its various aspects, the advantages of written catalogs, in particular the easy, pleasant and rapid nature of consultation, with the advantages intrinsically offered by the network, in particular the possibility of consulting the catalog everywhere, the possibility of perform database searches and lower cost for

catalog manufacturing.
