An Independent claim is made for a procedure for managing the address database and finding data records in memory (24) using a remote control (16) connected to the television. An address search in memory (24) is carried out in an iterative manner. Each iteration produces a list of addresses that can be selected with the number reducing with each iteration.

Description

The present invention relates to a method for producing a database in a television receiver. It also relates to a method of managing a database in a television receiver. It applies to all types of digital television receivers or more generally to all types of multimedia terminals that can receive information to be viewed. This information to be viewed is received on an antenna and / or by a cable connected to a data network. A commonly used data network is the Internet, but it could very well be a network linked to one or more data servers that can produce information on demand.

The object of the invention is to produce a database in a television receiver, or television, from visual information present in a received information message to view and also to manage, with the help of a remote control, a database in this TV. This database mainly comprises addresses allowing access to data servers or to all devices accessible by a computer network.

Today's television sets have an increasingly wide and varied use. Indeed, in addition to receiving television information, the television must also be able to receive multimedia type information from various computer networks, such as the Internet. Thus, a number of addresses available and carried, visually most often, to the attention of a viewer, in combination with a message received is considerable.

This strong development presents problems. Indeed, a user has more and more the need to manage all this address information. Currently, a user is not able to cope with such an offer without help in managing all this information. Indeed, given the amount of information that is sent, address information that may be of interest to the user are embedded in a multitude of information that is secondary to it. Consequently, a search for this address information among all these is all the more complex as the number of secondary information is large.

Another problem is using a keyboard to send a message to the TV. Indeed, a keyboard is bulky, impractical. Many users are concerned about having to use a keyboard to control a system, such as a computer, to which it is connected. This is mainly due to the large number of keys on a keyboard and the number of characters in the message.

Thus, with the invention, there is provided a solution for producing a database from address information displayed on a television, or more generally on a screen of a multimedia terminal. The main function of this database is to put forward address information of interest to a user. Thus, the user's preferred addresses are placed in this database. For this, one uses in particular an optical character recognition process implemented automatically or on demand.

In addition, with the invention, this database is managed and updated. For this, it implements a method of managing a database using a remote control of a TV as a control panel, a remote control with less touch than a keyboard. With this simple device that is the remote control is associated with a set of drop-down menus managed by the remote control.

In the invention, a character is defined as being a symbol of a writing. With this definition, symbols such as "A", "1", "@" or "V" are characters.

Use should be as simple as possible so that it can be easily accessed by a wide variety of users. As a result, any user can save address information by pressing a key on the remote control. In addition, any user can select in his database address information by pressing one or more buttons on the remote control. An implementation of such methods using a remote control reduces a cost price of such a television receiver since it removes the need for an extended keyboard. An extended keyboard is a keyboard whose key is usually associated with one or two symbols. It is appropriate to clarify a meaning of the term "address information" in the context of the invention. Address information is information indicating a source of a message to be received. For a message to be received from a computer network, this address information is mainly, but not necessarily, produced respecting the protocol IP (Internet Protocol). In this case, a receiver of the television sends a request, to be able to receive a message, comprising a header formed in particular with such address information.

On the other hand, in the case of a message to be received corresponding to a television program or any other television message, this address message corresponds to a channel number on which this program is broadcast. Thus, we set a TV receiver, commonly called English tuner or tuner in French, with this address information. Indeed, a channel number corresponds to a transmission frequency. The tuner is tuned to this frequency and messages transmitted with this frequency can be received. This definition of the address information is that used for the rest of the document.

The subject of the invention is therefore a method for producing a database in a television set comprising a television screen, characterized in that: - temporary image information representative of an image present on the television screen is temporarily memorized in this image information, seek information of a character relating to an address information, translate this character information into address information, and save the address information in a backup memory. , this backup memory constituting a database.

The subject of the present invention is also a method for managing address information in a database in a television with a screen, the television being connected to a remote control, characterized in that the database is organized in segments. information, each segment of information consisting of a sequence of characters that can be displayed on the screen, - information segments are associated with each other, one of which includes an address information, each association forming a line, - associates with a key of the remote control at least one character, - pressing a first key whose associated character corresponds to a first character of a segment searched in the database, - displaying on the screen a first list of values whose first character corresponds to the character associated with the key pressed, - one selects a value of a segment present in the first list of values with With the remote control, you set a TV receiver according to the address information associated with the selected value.

The present invention finally relates to a method for managing address information in a database in a database, or other memory, in a television with a screen and a modem, the television being connected to a remote control, in which - the database is organized into information segments, each information segment consisting of a sequence of characters that can be displayed on the screen, - information segments are associated with each other, one of which has information of address, each association forming a line, - associating with a key of the remote control at least one character, - pressing a first key whose associated character corresponds to a first character of a segment searched in the database, a first list of values is displayed on the screen, the first character of which corresponds to the character associated with the key pressed, and one value of a pre-segment is selected. in the first list of values with the remote control, characterized in that - one connects to the Internet network with the modem, - the address information associated with the selected value is transmitted on the Internet network. The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented only as an indication and in no way limitative of the invention. The figures show - Figure 1: a simplified representation of an architecture of a television receiver for carrying out the methods of the invention; - Figure 2: an example of a drop-down menu for adding information in a database and / or search information in this database; FIG. 3: a representation in the form of an algorithm of an exemplary operation of the method of producing a database; - Figure 4: an example of display on a screen of the television receiver during a search; FIG. 5: an example of a refined search of information in the database; FIG. 6: a representation in the form of an algorithm of an exemplary operation of the method of FIG. address management in a database.

Figure 1 shows a television receiver 1 or TV 1 in which is implemented the invention. This television 1 has a television screen 2 for displaying information messages to be viewed. The television 1 further comprises a receiver 3 connected to an antenna 4, receiving radio signals emitted by a transmitting station 6, and / or also connected by a link 7 to a network 8 of data such as the Internet network for example. The link 7 is generally a coaxial link but it could be an optical fiber connection or the like. The main function of the receiver 3 is to format received signals and to transmit them to a decoder 9. The decoder 9 comprises a microprocessor 10 and a program memory 11 in which a program 12 for producing a database is stored. data. The decoder 9 serves mainly to interpret a signal received by the receiver 3 and to transmit it to a device to which the signal received is intended. Indeed, information received by the receiver 3 is information to view or listen or both. The television 1 therefore comprises a device 13 for managing a display on the screen 2 and an acoustic signal management device 14 for a transducer 15, generally a loudspeaker. To allow a selection of a message received, among several, by the receiver 3, the TV 1 includes a remote control 16. This remote control 16 transmits a signal 17 received by a receiving device 18, generally a photo-sensor associated with means formatting the signal 17 received. The receiver 3, the decoder 9, the device 13, the device 14 and the device 18 are connected to a bus 19 of data, addresses and commands. In addition, the device 13 is connected to the screen 2 by a link in the form of a bus 20 and the device 14 is connected to the transducer 15 by a symbolic link 21.

Thus image information received by the receiver 3 is displayed on the screen 2. In the invention, this image information is temporarily stored. To temporarily store this image information, the device 13 may be used. Indeed, in a preferred example, the device 13 is provided with a main video memory (not shown), that is to say a memory in which is set image information representative of the image to be displayed on the screen 2. The image information is frozen on the screen 2 before temporarily storing the image information. That is, any new image information arriving while the image on the screen 2 is frozen is not taken into account. To achieve this, a content of the main video memory is maintained in a frozen state for a duration at least equal to a time necessary to search for and possibly translate a piece of character information.

The program 12 controls the microprocessor 10 to search in the main video memory for character information relating to an address information. The program 12 is generally referred to as an optical character recognition method. The program 12 makes it possible to search in the main video memory for a portion 22 of the image 23 displayed on the screen 2. This portion 22 corresponds to a visual representation of an address information item. The program 12 then translates this character information into address information. The decoder 9 controls a backup of this address information in a backup memory 24. The memory 24 thus forms a database. In this memory 24, the address information is organized in the form of a table 25. In a preferred example, the table 25 includes a list of address information stored in the form of a list of lines 26 comprising two fields 27 and 28 per line. In the field 27, a value of an address information thus obtained is placed and in the field 28 a value of a keyword is placed making it possible to name the value of the address information of the field 27 by a value generally chosen by the user. Indeed, a value of an address information is, in the case of a network, a character string of the form http: llwww.nom1.fr. In a preferred example, a value of the keyword in the field 28 corresponds to name1, but any other value that one wishes to associate with the address information could be used. In the invention the term value has as well meaning a number as a word, this term being used only to illustrate a notion of content of a field or segment.

In one example, a temporary storage of image information is performed on demand. Thus, when a viewer sees on the screen 2 an address appearing to be interesting then he asks for a backup of this character information in the list 25 of the memory 24 in the form of address information.

To request a backup of address information the viewer uses the remote control 16. The remote control 16 has several keys that can be grouped into two main groups according to functions for which they are intended. A first group of keys 29 includes keys for selecting a channel and a second group 30 for performing selection and validation functions from a general control menu of the TV 1.

As a result, the group 30 includes a menu call key 31, a label selection key 32 in a menu, a function validation key 33 associated with a selected label, and a group 34 of softkeys. moving to move in a menu. Thus, to summarize an operation of the remote control 16, pressing the key 31 to call up a menu, one moves in this menu to choose a label with the group 34, one selects the label chosen with the key 32 as long as one is in intermediate menus, then after a choice to validate a choice of a label is pressed by pressing the key 33. Figure 2 shows an example of a drop-down menu that could be displayed on the screen 2. Thus after pressing the key 31 (FIG. 1), there appears a menu 35 comprising a list of labels. In a first example, the menu 35 shows a label 36 corresponding to a general menu. This menu 35 further comprises a label 37 making it possible to implement the method of producing a database of the invention. With the group of keys 34 one moves in the menu 35 and one chooses the label 37. In a preferred example and in order to indicate an authorization of the choice of the label 37, one highlights the label 37. To emphasize the label 37 one can change a color of a wallpaper or highlight a content of the label 37 or any other means to put information in value compared to other information. Pressing the selection key 32 makes it possible to select the label 37 thus selected and consequently controls the display of a backup menu 38. In this first example, the menu 38 includes an activation label 39 of the optical character recognition method. Pressing the key 33 validates this activation.

In a second variant, image information is temporarily stored in the list periodically. That is to say, in this variant the microprocessor 10 of the decoder 9 automatically manages, under the control of the program 12, a storage of address information. To do this, the decoder 9 copies in an auxiliary video memory (not shown) of the device 13 a content of an image information to be displayed. An operation of the auxiliary video memory is the same as that of the main video memory except that it can freeze a content. The image information is placed in an auxiliary video memory in order to avoid, in a preferred example, freezing an image displayed on the screen 2. In fact, since the method is automatic, the viewer would be disturbed by periodically freezing the image. on the screen 2. In a preferred example of this variant, the viewer is left with the choice to authorize or not an automatic control of the backup of address information.

In a third variant, a portion of the image information containing the character information is temporarily stored. This makes it possible to lighten the processing of the decoder 9. In fact, instead of completely processing the image displayed on the screen 2, only the part of the image containing the character information is processed. In order to select, in a preferred example, that portion of the image which includes the character information, the area corresponding to the part of the character information is selected on demand. To allow this function, the menu 35 is modified. More precisely, instead of validating the label 39 by the key 33, it is selected by the key 32 and a submenu 40 is displayed, including in particular a selection label 41. a portion of the image information displayed on the screen 2 that is to be processed with the optical character recognition method.

Thus, validation of the label 41 causes a visual element to be displayed on the screen 2. In a preferred example, the visual element is an image of a point. However, any other visual element could be displayed on the screen 2 to allow the user to have a landmark to select the portion 22 such as a cursor. In this preferred example, it is considered that a part such as the part 22 that one wants to treat is of rectangular shape. Thus, with the group 34, this point is positioned at a first corner of this rectangular shape and this position is selected with the key 32, then the point 34 is moved again with the group to position it at a second corner diagonally opposite the first corner. . The rectangle thus formed is highlighted from these two corners and pressing the key 33 validates the part 22 thus highlighted during this support. To highlight, in a preferred example, a background color of the part 22 is modified. Then the optical character recognition method is activated.

In the submenu 40 can also be displayed a label 42 relating to an automatic registration of an address information by periodic searches. A selection of the label 42 brings up a submenu 43 having a label 44 for validating an activation of this automatic operation and a label 45 for disabling such operation. In addition, a label 46 is displayed in the menu 40 that activates a default operation of the optical character recognition method for processing the entire image information.

In a preferred example, the remote control 16 is provided with a shortcut key 47 to activate the optical character recognition method. This key 47 is active when the label 41 or 46 is validated. In this case, after pressing the key 47 and when the label 41 is activated, an image of a point then appears on the screen 2 in order to select, as previously, a part of the present image. on the screen 2. In the case where the label 46 is activated, pressing the key 47 has the effect of freezing the image on the screen 2 and start the process of optical character recognition. In this preferred example, one could consider a first pressing of the key 47 activates a function associated with the label 41 or 46 and a second pressing of the key 47 cancels this activation.

The decoder 9 thus saves an address information in the memory 24. It is proposed, in a preferred variant, the viewer to set the receiver 3 of the TV 1 according to the address information obtained in order to view information from of this address information. The proposal made to the viewer to accept or not the setting of the receiver 3 is made in the form of a visual message displayed on the screen 2 and / or in the form of a sound message transmitted with the transducer 15. A support on the key 33 allows, for example, the decoder 9 to set the receiver 3 according to this address information and pressing the key 32 is interpreted by the decoder 9 as a refusal of the user.

In the case where the address information is an IP address then the receiver is connected to a modem (not shown) or, alternatively, includes this modem or realizes the features. Thus, the TV 1 is connected to the Internet with the modem. The address information is then transmitted on the Internet.

All the processing means associated with the optical character recognition method are controlled by the decoder 9. It may be envisaged in a variant to delegate this processing to an external microprocessor 100, ie located outside the television set 1. Thus , the television 1 has a device 48 interface. This device 48 makes it possible, in a preferred example, to make a serial link of the RS232 type. The microprocessor 100, placed for example in a computer, is connected to the device 48 via a link 49. Thus, when the optical character recognition method is activated, a content of the video memory associated with the image displayed on the screen 2 or at the part 22 is sent via the bus 19 to the device 48 and with the link 49 to the computer 47. The latter returns as a result the address information produced. It could also be envisaged to provide the computer 47 with a screen 50 in order to display the image information and possibly to be able to carry out additional treatments.

FIG. 3 shows in a representation in the form of an algorithm of an exemplary operation of the method of producing a database in the television set 1 according to the invention. Thus, in a first step 51, a request for an image capture is awaited. This request comes from pressing the key 47, a choice of the label 41 or a label 46 or automatically when the label 44 is validated. In the case of an image capture request, the decoder 9, in a step 52, temporarily stores a content of an image information representative of an image present on the screen 2. Once this image has been stored the program 12 activates, in a step 53, an optical character recognition method with which this information is searched for character information relating to an address information. After analyzing the image information during the phase 53, a test step 54 is checked whether or not in this image information character information has been found. In the case of a positive response to the test of step 54, a memorization of the address information obtained after transforming the character information into an address information is carried out in a step 55. In a step 56 it is proposed to the viewer the possibility of setting the TV 1 with the address information thus obtained. In the case of an acceptance on the part of the latter, the receiver 3 is set in a step 57 as a function of the address information obtained. In the case of a negative answer to this proposal, no adjustment of the receiver 3 is made.

In the case where a negative answer to the test of step 54 is obtained, this means that either there is no character information in the stored image information or program 12 can not identify the character information because it is too complex form for the program 12 for example. In this case, the decoder 9 displays, in a step 58, an alarm message indicating that the optical character recognition method has failed. However, in a preferred example and following this display it is proposed, in a step 59, the user to provide help by selecting a portion of the image, if it exists, containing the character information. This proposal results in an on-screen display of the submenu 40 by highlighting the label 41 of selection of a window in the image displayed on the screen 2. If on the other hand the user refuses to provide his help, then it responds negatively to the help request message by pressing the 32 key for example.

The present invention also relates to a method of managing address information in a database in the television 1. The database is organized into information segments. Each information segment consists of a series of symbols that can be displayed on the screen. The database is produced mainly as previously, in particular for the production of the list 25. In fact, it is possible to match an information segment with a field such as the field 27 or the field 28. We also associate segments information and lines 26, 73 or 78 are obtained. Each line has address information. The decoder 9 thus comprises in the memory 11 a management program 60. With this method, an address information is sought in the memory 24 as a function of a code transmitted by means of the remote control 16. Rather than searching for address information, a value is sought in a preferred example. of a keyword present in a field 28 associated with an address information present in a field 27. Indeed, it is easier to distinguish two keywords between them than two address information among them which often have prefixes identical, such as the prefix HTTP: 11www in the case of an IP address.

Thus, it associates with a key of the remote control 16 at least one character. In a preferred example, a number of characters is associated according to a number of keys present in group 29. For example, and considering nine keys useful for a search in group 29, the characters A, B, C to a first key 61 of the group 29. The characters D, E and F are associated with a second key 62 and so on for the other keys of the group 29. However, any other criterion of association between a key can be chosen. and a character.

In order to be able to search for a value of a key word in the memory 24, it is first selected in a search mode. Thus, the menu key 31 is pressed, and the menu 35 is displayed. This menu 35 comprises, in addition to the label 36 and the label 37, a label 63 relating to a search menu. A validation of a function represented by this label results in a display of a submenu 64 for selecting a type of address information that we want to search. The menu 64 comprises for this purpose a label 65 relating to an address information of a computer network, a label 66 relating to an address information of a television channel and a label 67 relating to an address information of a broadcasting station. Thus, after a selection of one of the labels 65 to 67, the decoder 9, more precisely the program 60, knows a type of address associated with an address information to be searched in the database.

In the case of a selection of the label 65 is displayed a submenu 68 having a label 69 indicating that the search is done using the content of a field 27 and a label 70 indicating that the search is done using a content of a field 28.

Each type of address is grouped in the memory 24 in a list. Thus the list 25 (FIG. 1) is used for a computer network address, a list 71 is used for an address of a television channel and a list 72 is used for an address of a broadcasting station. In a preferred example, the list 71 is produced from program information received by the receiver 3 via the antenna 4 or the link 7 if a network 8 is a network providing video type information. . The list 71 is updated, by the decoder 9, after each new reception of a program by the receiver 3. In this program, it preferably indicates a type of broadcast, a broadcast schedule of this program, a channel on which this program is broadcast, and possibly various secondary information. The list 71 is produced in the form of a series of lines 73. A line 73 comprises, in a preferred example, a field 74 relating to a type of transmission, a field 75 relating to a broadcasting schedule of this program, time consisting of time information and / or date information, a field 76 relating to a channel or channel number on which this program is broadcast and a field 77 in which secondary information is stored or keywords such as for example names of actors, directors or others.

The broadcast station address information storing list 72 is organized in a preferred example into a succession of lines 78 having a field 79 relating to a frequency value with which a program to be listened to is broadcast. field 80 relating to a name associated with this frequency value.

When the label 66 is selected in the menu 64, a submenu 81 is displayed in which there is a label 82 relating to an address information search by type using a content of a field 74 of the 71. In the same spirit, the submenu 81 includes a time search label 83, a search label 84 by channel. The submenu 81 further includes a label 85 for a keyword search that is to say that all fields 74 to 77 of a line 73 are read.

A selection of the label 67 relating to a search for address information of a broadcasting station displays a submenu 86 having a label 87 relating to a search by a name of a broadcasting station. ie using a content of a field 80 of a line 78. The submenu 86 also includes a label 88 allowing a search using a content of a field 79 that is to say using a frequency value.

However, it may happen that a content of two fields of two different lines is identical. As a result, the decoder 9 displays all the corresponding address information. The user only has to select the address information that interests him among all those found. For example, if a user searches by type and searches for address information associated with an action movie then the decoder will display all the address information broadcasting an action movie. The decoder could also display additional information associated with each address information such as broadcast schedules.

Figure 4 shows an example of display on the screen 2 during a search phase. The screen 2 comprises, in this example, a window 89 in which a code representative of an address information that a user searches can be displayed. In a preferred example, a displayed code represents a code of a key pressed. This code is usually a number. A character is associated with a key. Thus, a code is the same for all the characters of a key.

The screen 2 also includes a window 90 displaying a result of a search. To start a search, the user presses a key of the group 29 whose associated character corresponds to a first character of the word used for the search. In a preferred example, this first character corresponds to the first character of the word used, but it could be another. In this case, this other character is considered more meaningful than the first character because, for example, of an originality distinguishing it from another word. This originality allows to somehow code the word used and therefore to differentiate it completely from another word that can be the same to this character. In the following, we therefore consider that this first character is the first character of the word used. Thus, in the window 90, a list of possible values of a type of field considered, or segment, whose first character corresponds to one of the characters associated with the pressed key is displayed.

In an illustrative example, an address information of a computer network is sought by using a keyword, that is to say, a function associated with the label 70 is valid. In this example, the word is used. key "FAMILY".

One thus seeks an information of address associated with the key word "FAMILY". First, the key 62 associated with the characters D, E and F is pressed. This is reflected in the window 89 by the display of a digit associated with the key 62, for example the number two. Thus, in the window 90 the decoder 9 displays all the key words starting with the letter D, the letter E and the letter F.

A first continuation is to search for the desired keyword in the list displayed in window 90. This solution can be used if there are only a few keywords in this list. It is preferred to press a second key of the group 29 whose associated character corresponds to the second character of the searched keyword, "A" in the example. On the screen 2, FIG. 5, a list of keywords is displayed in the window 90, the first character and the second character of which correspond to the characters associated with the pressed keys.

With the example of the keyword FAMILY, the second key pressed is the key 61, for example the number one. Thus the decoder 9 displays in the window 90 all the keywords whose first character is a D and the second character an A or B or C and all the keywords whose first character is an E and the second character an A or a B or a C and finally all the key words whose first character is an F and the second character is an A or a B or a C. Thus decreases a number of information present in the list 90. If the list is small enough, we can select a keyword among the key words present, or then we start with a press on a third key to further reduce the list in the window 90 and until we get the only key word searched for a sufficiently small list to select the desired keyword.

In this example, it is considered that pressing the keys associated with the characters "F", "A" and "M", for example the keys of number two, one and five respectively, is sufficient to obtain a list of three words. key. However, we could further refine the search by pressing the key associated with the character "I" and so on.

However, in a preferred example, the code is written digit by digit in the search window 89. In this preferred example, each address information is associated with a quantization of audio measurements. Thus, it is proposed, highlighted in the list of keywords proposed in the result window 90 and after pressing a key, the word whose quantification of audimetry is the strongest. For this purpose, each line 26, 73 and 78 is provided with an additional segment (not shown), each additional segment comprising a quantization. Thus, with each new key press, the highlighted word is updated based on the words remaining in this keyword list.

The keyword FAMILY is displayed as many times as there are lines containing this keyword. However, to avoid having a display in the window 90 of several times the same keyword then we associate, in one variant, additional information, including a content of another segment, to a displayed keyword. This additional information may be an address information for example or even a second keyword. More generally, a search word of a line 26, 73 or 78 is displayed which is associated with a content of another field of this line in order to distinguish two possibly identical displayed words.

In a preferred variant, a key of the group 29 is associated with a number of characters inversely proportional to a probability of using these characters. Thus, the key associated with the "E" character that is often used is associated with a restricted number of characters. In contrast, a key associated with the character "VV", less used, is associated with a larger number of characters, for example the characters "XYZ", also possibly little used. In this case, it is limited by means of the remote control 16 a number of words present in the window 90. Indeed, it searches all the words having, at a given position, the characters associated with the key pressed. By associating with the pressed key few characters, so decreases a workload of the microprocessor 10 having fewer criteria to check and therefore searches to perform. If on the other hand there are more characters associated with the pressed key, then it means that these characters are not used and that therefore found words will be all the less numerous that such a key is supported in ending the search word. This makes it possible to converge a search more quickly towards the desired address information.

FIG. 6 shows a representation in the form of an algorithm of an exemplary operation of the management method of the invention. In a waiting step 91, a selection of a search mode is expected in the submenu 64. As soon as a search mode is selected, a value of a given segment type is searched in a step 92 in one of the lists 25, 71 or 72, the first character of which corresponds to one of the characters associated with the first key pressed. In the window 90, a first result list is displayed. A second key is pressed and, in the first result list, all the values whose second character corresponds to one of the characters associated with the second key pressed are searched, and so on. Once the value sought is only present in the window 90 or when the list present in the window 90 is deemed sufficiently reduced by the user, the desired value is selected in a step 93 using the remote control 16. For this, selects the value sought with the key 32 and the group 34. In a test step 94, it is expected a validation, with the key 33, the selection. Validation has the effect, in a step 95, of telling the decoder 9 to search the memory 24 address information associated with the desired value and send it to the receiver 3 to adjust the latter consequence as above. A non-validation has the consequence of canceling this search.

An alternative is to store in the memory 24 address information produced by the user. Thus, the menu 38 includes a label 101 for saving an address information. A selection of this label 101 has the effect of displaying a menu 102 having a label 103 whose selection allows to save only address information. The menu 102 further includes a label 104, a selection of which saves an address information but also an associated keyword or other information. To implement this backup, allowing an update of the database, the remote control is used as a keyboard. To display a desired character can be implemented various known techniques such as for example a repeated pressing a key to scroll the characters associated with this key. For example, if you associate with a key the characters A, B and C then to reach C you press this key three times. The memorization is confirmed by pressing the key 33.
