STATE OF THE PRIOR ART
Currently, it is quite common that in road journeys the coverage of a particular radio station on frequency modulation (FM) is lost, since this is the most used service, rather than the medium wave (AM), especially on routes where the terrain is craggy.
Generally, FM radio broadcasting have a typical coverage between 50 and 70 kilometers, after which, if the receiver is of type RDS (Radio Data System) it can be sought automatically the same radio station in another post or antenna if the broadcast has been properly codified. The RDS technology is a standard of the European Broadcasting Union to send a small amount of digital information, such as the code of the broadcasting network, using radios of the type conventional FM.
However, in a majority of cases, stations have no other transmitting antenna so the coverage is lost, forcing the user to distract and manually locate a new station, which does not to have to be in accord with his/her liking or needs. Similarly, it may also be the case, the same station, in various posts, does not contain the same coded information, so the RDS system becomes useless (this event occurs often when it comes to “associated” posts but with different ownership with respect to the main broadcasting network).
It is therefore necessary a method and a device to inform the user about a given broadcast in a given geographical point regardless of the digital information provided by broadcast (RDS) and under some profiles predefined by the user.
Another technical problem that arises now is that the broadcasts of multimedia content on demand over the Internet, known as streaming, have become popular in recent years, together with the improvement in communications and access systems to internet via mobile phone. It is therefore interesting to get a method and a device allowing the connection with the radio broadcast chosen via streaming, when the main broadcast via radio is lost, regardless of the digital information provided by broadcast (RDS) and under some profiles predefined by the user.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
Example 1
Location of the User Position by GPS Coordinates
As can be seen in the accompanying figures, and more specifically in the FIG. 1 the device and method object of the present invention starts, in its preferred embodiment, with the definition of a plurality of profiles, in a database of profiles (1) integrated into the device (10) with a capacity of location and GPS-type navigation.
In this first database of profiles (1) the user will define, at least, a profile of listening by means of a plurality of fields (11), wherein these fields are, by way of non-limitative example, the language of broadcast, the station category (radio formula, general, sports, etc.), and/or the type of programming broadcasted at that specific time (economic information, classical music, sports broadcasts, etc.).
Similarly, the second database of radio stations (2) defines a plurality of stations categorized with the same fields as the first database of profiles (1) and including, in addition, an extra field (13) with the location coordinates of the transmitting antenna and another with the dial of said antenna (14). With these data it will be enough the location, therefore it is understood that the coverage of said antennas will be comprised up to a maximum of 70 km without taking into account the orography of the terrain, being able to implement an algorithm that, depending on the orography or the terrain will reduce the radius of coverage, since, for mountainous areas, is rarely possible locating a radio station at a distance greater than 20 km.
In the next stage of the method, the GPS device will define the location coordinate (4) of the device (10) and, therefore, of the user, establishing a search of the station suitable for this particular position, according to the following algorithm (3), as shown in the FIG. 2:












Start (100)


{


  If current_position = then “x” searchs_station_position (101);


  {


    if station_position == current_position (102);


    {


      then searchs_user_profile (103);


      if station_profile == user_profile (104);


      {


        then shows_dial (105);


      }


      if no message displayed (“no appropriate profile”);


      station list (104A);


    }


    if no message displayed (“no stations in coverage”); (103A);


  }


}


in other case return (100);









That is, first of all, the matches (101) of the current position (4) will be sought with the station position (13), which has a radius of coverage variable depending on the orography, for example 70 km for flat terrain and 20 km for mountainous terrain.
At the time that match (102) in the second database of stations (2) is located, it seeks that the preferences (103) defined by the user in the first database of profiles (1) match between them (104), showing the dial in positive case (5, 105).
If not, and if the cause is the lack of profile (104A) a message of the type “out profile stations” will be display but listing stations with coverage, in case the user decides to change the profile or listen to another type of station regardless of the defined profile. Finally, if the cause is the lack of coverage of any station, a message of lack of coverage (103A) will be displayed.
In any case, always it will be indicated the distance remaining until the next coverage area, so that the user is informed.
The method of the invention, in other preferred embodiment, comprises a recording stage of a second favorite broadcast, in such a way that it can subsequently be broadcasted at the user's will. This means that, for example, if the route runs through an area where there is no coverage either there is no appropriate listening profile, the user is able to reproduce a broadcast that matches with their linking but it happened while he/she listened to another live program.
Similarly, the method comprises a stage of reproduction of routines of radio broadcast based on the route selected by the user. Thus, one possibility is to define a listening profile for a specific route, for example, always listening news when I return home or similar.
The method regularly repeats every “t” time periods. In a preferred embodiment, the GPS device and radio will be integrated, the dial being launched automatically to the radio and connecting.
Another point to consider is the possibility that the complete management of the radio is carried out from the device itself (10) with a built-in radio receiver and connecting with the vehicle radio itself for broadcasting the signal received in a gap of the spectrum wherein there is no emission.
Example 2
Location by Identification of Mobile Telephony Cells
As can be seen in the accompanying figures, and more specifically in the FIG. 3 the device and method object of the present invention starts, in its preferred embodiment, with the definition of a plurality of profiles, in a database of profiles (21) integrated into the device (210) with a capacity of location by identification of the mobile telephony cells in coverage and/or WiFi antennas.
In this first database of profiles (21) the user will define, at least, a profile of listening by means of a plurality of fields (211), wherein these fields are, by way of non-limitative example, the language of broadcast, the station category (radio formula, general, sports, etc.), and/or the type of programming broadcasted at that specific time (economic information, classical music, sports broadcasts, etc.).
Similarly, the second database of radio stations (22) defines a plurality of stations categorized with the same fields as the first database of profiles (21) and including, in addition, an extra field (221) with the location coordinates of the transmitting antenna and another with the dial of said antenna (222). With these data it will be enough the location, therefore it is understood that the coverage of said antennas will be comprised up to a maximum of 70 km without taking into account the orography of the terrain, being able to implement an algorithm that, depending on the orography or the terrain will reduce the radius of coverage, since, for mountainous areas, is rarely possible locating a radio station at a distance greater than 20 km.
In the next stage of the method, the device will define the location coordinate (224) of the device (210) based on the available mobile telephony cell and, therefore, of the user, establishing a search of the station suitable for this particular position, according to the following algorithm (23), as shown in the FIG. 4:












Start (200)


{


  If current_position = then “x” searchs_station_position (201);


  {


    if station_position == current_position (202);


    {


      then searchs_user_profile (203);


      if station_profile == user_profile (204);


      {


        then shows_dial (205);


      }


      if no message displayed (“no appropriate profile”);


      station list (204A);


    }


    if no message displayed (“no stations in coverage”); (203A);


  }


}


in other case return (200);









That is, first of all, the matches (201) of the current position (24) will be sought with the station position (221), which has a radius of coverage variable depending on the orography, for example 70 km for flat terrain and 20 km for mountainous terrain.
At the time that match (202) in the second database of stations (22) is located, it seeks that the preferences (203) defined by the user in the first database of profiles (21) match between them (204), showing the dial in positive case (25, 205).
If not, and if the cause is the lack of profile (204A) a message of the type “out profile stations” will be display but listing stations with coverage, in case the user decides to change the profile or listen to another type of station regardless of the defined profile. Finally, if the cause is the lack of coverage of any station, a message of lack of coverage (203A) will be displayed.
The method of the invention, in its second practical embodiment, as a special feature, comprises a recording stage of a second favorite broadcast, in such a way that it can subsequently be broadcasted at the user's will. This means that, for example, if the route runs through an area where there is no coverage either there is no appropriate listening profile, the user is able to reproduce a broadcast that matches with their linking but it happened while he/she listened to another live program.
Similarly, the method in its second practical embodiment comprises a stage of reproduction of routines of radio and/or television broadcast depending on the route selected by the user. Thus, one possibility is to define a listening profile for a specific route, for example, always listening news when I return home or similar.
The method in its second practical embodiment regularly repeats every “t” time periods. As a special feature, the mobile device and the radio and/or television will be integrated, the dial being launched automatically to the radio and/or television and connecting.
In another peculiarity, the method in its second embodiment comprises an additional stage of GPRS data sending from the device to the radio and/or television station, being these data variable from the simple listening notification to participation in any type of competition, for example.
Example 3
Location of Radio Stations with on-Demand Downloading
As can be seen in FIGS. 5 and 6, the device that implements the method object of the present invention in its third practical embodiment, starts defining at least one profile in a first database of profiles (31), integrated in the device (310) capable of remote data connection, via mobile phone, preferably GPRS/UMTS, or equivalent.
In this first database of profiles 31 the user will define, at least, a profile of listening by means of a plurality of fields 311, wherein these fields 311 are, by way of non-limitative example, the language of broadcast, the station category (radio formula, general, sports, etc.), and/or the type of programming broadcasted at that specific time (economic information, classical music, sports broadcasts, etc.).
Similarly, the second database of radio stations 32 defines a plurality of stations with their corresponding on-demand downloading URL addresses 321, being said stations categorized with the same fields as the first database of profiles 31.
In a second stage of the method a threshold of loss of coverage of the broadcast is established, from which the method will connect to a broadcasting URL address according to the algorithm shown in FIG. 6 and which is defined below:
The algorithm begins 300 analyzing whether there is or no coverage for the current broadcast 301; if so, the algorithm ends at the beginning 300, establishing a loop by checking that there is or no coverage for the broadcast.
In the event that the coverage is negative, the algorithm seeks the URL address 302 in the second database of stations 32, connecting with it, and consequently revealing if the link is available 303 or truncated 304. If it is available 303, a loop of analysis of coverage and connection with the URL address is established so that when the coverage of the broadcast is recovered, the on-demand broadcasting URL address is disconnected, thereby optimizing resources.
In the event that the current broadcasting URL link is truncated 304, all those stations 305 that correspond to the user profile 306 selected are sought. Once a match 307, 309 is found, the selected station(s) 309 is displayed, being shown to the user and/or selecting 3110 one of them by default, closing the loop. In the event that there is no match 308, a message of “not appropriate profile” will be displayed closing the loop at the start.
The method of the invention, in another particular embodiment, comprises a stage of downloading the remote podcast (podcasting is the distribution of multimedia files (usually audio or video) through a syndication system which allows the subscription and the use of a program which downloads it so the user listen it when he/she wants). There is no need to be subscribed to download them), for which, the database of radio stations must comprise an additional field 322 with the downloading URL of the file that will be stored in the memory of the device itself 310, being reproduced in the case that there are no matches 308 between profiles and stations or even in preference to the search for new stations, if the favorite URL is not available 304.
Similarly, the method in its second practical embodiment comprises a stage of reproduction of routines of radio and/or television broadcast depending on the route selected by the user, if the device comprises global location means of the type GPS. Thus, one possibility is to define a listening profile for a specific route, for example, it would be possible to define “always listening news on the route to work”.
The method regularly repeats every “t” time periods. In a preferred embodiment, the mobile device and the radio and/or television will be integrated 35, the broadcast being launched automatically to the radio and/or television, and playing it.
In general, all of the above-mentioned in present specification is applied indistinctly, if it would want for television broadcasts.
