The present invention relates to a method of synchronizing at least one media peripheral devices, portable communication devices, such as mobile phone, with a synthetic audio file.

The phrase "multimedia peripherals" refers to different nodes portable communication that can be activated in synchronization with music, for example, in the case of mobile phone:

- calling device to alert the user in case of reception of an incoming call or message;

- a means of vibrator that can be used either instead of or in conjunction with a call;

- rear backlight, which is used to illuminate the display device;

- backlight used to illuminate one or more keys on the keypad;

any specialized luminous devices such as LEDs, which could be provided on the mobile phone.

Synthetic sound files apply to all varieties of files that contain digital data, enabling the synthesizer to generate music or melody, such as standardized files, known as MIDI (an acronym for digital interface musical instruments) or SP-MIDI, or SMAF (an acronym for the format of mobile applications syntheti the Russian music). More precisely MIDI files do not contain any sound. In fact, they are text files containing the coded commands that allow the synthesizer to play the notes. Numbers specify the position of each note relative to the beginning of the music and its time value, as well as its volume, including crescendo and diminuendo. Other commands set tools (for example, 1=piano, 74=flute) for each track/channel, a change of pace and the overall sound level and stereo balance for each track.

Supply of portable communication devices, such as a mobile phone, a means for synchronization of one peripheral media device, as defined above as non-restrictive examples with synthetic sound file is already known.

Usually synthetic files used for these specific applications, are special because they contain a specific tool that should be used for synchronization of one peripheral media device, such as a tool 125 in the case of a ringing tone or the tool 12 in the case of a call of a vibrator of the mobile phone. Special synthetic files can be loaded into memory of the mobile phone at the time of manufacture. Alternatively, the user can download the new synthetic files either through the cellular network, which mobile phone is connected, or via any type of network, including the Internet, or from a PC (personal computer PC). Once these files have been downloaded and stored in memory on the mobile phone, the user typically has the ability through the special menu, choose file, which can be used to synchronize each multimedia peripherals, provided his mobile phone.

The ability for the user to specify the characteristic features for portable communication devices, therefore, is limited by the fact that offers manufacturers or network operators or service providers. However, synthetic sound files, which are not always correspond to the user preferences.

More choice could be provided to the user, if he could use any type of synthetic sound files, even those that were not created in order to synchronize multimedia peripherals portable communication devices. However, in this case, if the file does not contain any information for synchronization (for example, a single track, or related to the tool 125 or to the tool 12), the user will not be able to use this file for synchronization purposes.

The aspiration of the invention is to IDMS is to provide the above drawback by proposing solutions giving the opportunity to systematically synchronize media peripheral device with the information coming from any type of synthetic sound file, whatever the content of this audio file, and is particularly even in the case in which no synchronization information is not contained in this audio file.

About this commitment the purpose of the present invention is to provide a method of synchronizing at least one media peripheral devices, portable communication devices with synthetic audio file containing the step of forming at least one synchronization signal from the above-mentioned synthetic sound file, characterized in that it further comprises the following steps:

the initialization phase consists in memorizing in said portable communication device of parameters that include at least a list of preferred instruments;

the stage of the formation containing the analysis phase of information read from the mentioned synthetic audio file that is specific to each instrument, which can be extracted track, in the above-mentioned synthetic audio file, and the decision-making stage, which extracted the track should be used for the formation of this signal si is chronic, as a function of these parameters;

these parameters also include predefined threshold frequency, the said stage of the analysis information further comprises determining the frequency of occurrence of the notes mentioned in the synthetic audio file for each of the extracted paths, and referred to the decision-making stage consists in selecting the extracted paths, corresponding to the tool, which belongs to the above list of preferred instruments according to the comparison between the frequency of occurrence of the notes and the above-mentioned predetermined threshold frequency.

For example, the extracted path can be selected if it meets the instrument that belongs to the above list of preferred tools, and if the frequency of the music for this track is greater than or equal to the aforementioned predetermined threshold frequency value.

According to one of the possible embodiments of the invention, the above method may further comprise the step of determining whether the track synchronization in the above-mentioned synthetic audio file.

If the track synchronization is determined, the track synchronization can be automatically selected for forming the above-mentioned synchronization signal. As is lternative can be resolved to elect another track as a function of these parameters even in the case if the track synchronization was found. Alternatively, can also be decided to choose the best path among any track synchronization or other extracted paths is selected as a function of these parameters.

In any case, the method according to the invention gives the user the ability to use any kind of synthetic audio file, in any case, the presence or absence of track synchronization in this file.

According to the invention mentioned the decision-making stage preferably consists of selecting the extracted paths, corresponding to the tool, which belongs to the above list of preferred tools.

The above parameters can also include information of priority for each preferred tool. In this case, the extracted path is preferably chosen in accordance with the above information priority.

The second aim of the present invention is a portable communication device, containing at least one media peripheral device that can be activated in synchronism with at least one synchronization signal generated from the synthetic audio file, characterized in that it contains:

means for storing in the above paragraph is stationem device communication settings, includes at least a list of preferred instruments;

means for reading and analyzing information read from the mentioned synthetic audio file that is specific to each instrument, for which the track can be extracted, in the above-mentioned synthetic audio file; and

means for selecting which extracted the track should be used for forming the above-mentioned synchronization signal, as a function of these parameters, and to generate the above-mentioned synchronization signal;

and these parameters also include predefined threshold frequency, the said means for reading and analyzing is adapted to determine the frequency of occurrence of the notes mentioned in the synthetic audio file for each of the extracted paths, and the selector selects the extracted paths, corresponding to the tool, which belongs to the above list of preferred tools, according to the comparison between the frequency of occurrence of the notes and the above-mentioned predetermined threshold frequency.

Other characteristics and advantages of the invention will be apparent from the following description of embodiments of the invention, given only as non-restrictive examples and with reference to the accompanying che is the intellectual property, on which:

1 schematically shows the different steps involved in the method according to the first possible variant of implementation of the present invention;

figure 2 shows an example of extracting synchronization according to the present invention for a specific example of the MIDI file;

figure 3 schematically illustrates a possible means to implement the method according to the present invention.

In connection with figures 1 and 2, the method of synchronization, at least one media peripheral devices, portable communication devices according to the invention consists in forming at least one signal Sisynch synchronization from this synthetic audio file 1.

According to the first aspect of the invention, the method includes a step (A0initialization, during which some of the parameters 2, which includes at least a list of preferred tools, remembered at the level mentioned portable communication devices.

The above-mentioned step (A0initialization can be performed in the manufacture of portable communication devices. Alternatively, or in combination with an appropriate menu can be configured by the user.

In the example shown in figure 2, the list of preferred tools contains two of the most preferred tool, namely the tool is NT No. 32 (corresponding to an acoustic guitar to MIDI standard) and instrument No. 1 (corresponding to the piano to MIDI standard).

According to the second aspect of the invention is the stage of A1the formation containing the step (A10analysis of the information read from the synthetic audio file 1 and are specific to each instrument, which can be extracted track, in the above-mentioned synthetic audio file, and the step (A11the decision, which removed the track should be used for forming the above-mentioned synchronization signal as a function of these parameters;

For illustrative purposes, let us assume that the synthetic audio file 1 contains several tracks corresponding to several tools, among which we can find, as illustrated in Fig. 2, at least the following tracks:

- track relating to instrument No. 1 (piano), with appropriate notes should be played for this tool;

- track relating to instrument No. 32 (acoustic guitar), with appropriate notes should be played for this tool;

- track related to tool No. 15 (tubular bell), with appropriate notes should be played for this tool;

In the example of figure 2, the score corresponding to each of the instruments was given for a duration of one second. Of course, more p is Etienne duration.

During step (A1formation, and more precisely during step (A10at least these three audio tracks will be extracted.

Stage a11the decision in this case will be to select the extracted paths, corresponding to the tool, which belongs to the above list of preferred tools. The extracted path corresponding to the tool number 15, is not considered because it does not belong to the list of preferred tools.

In this preferred embodiment, the parameters 2 also includes the information of the priority for each preferred tool. In this case, the extracted path will be chosen preferably in accordance with the above information priority. For this example, the information of priority has been set to priority 1 tool No. 32 and priority 2 tool No. 1, which indicates that while both of the audio track corresponding to both instruments can be found in the synthetic audio file 1, preference will be given instrument No. 32.

Others may be added settings: in the preferred embodiment, the parameters 2 also include predefined threshold value of probability or frequency. In this case, the step (A10analysis details is rmacie further comprises determining the frequency of occurrence of the notes mentioned in the synthetic audio file 1 for each of the extracted paths, and stage a11a decision consists in selecting the extracted paths, not only the relevant instrument, which belongs to the above list of preferred tools, but also according to the comparison between the frequency of occurrence of the notes and the above-mentioned predetermined threshold frequency. The comparison may be to select a track only of the number of extracted audio tracks, for which the frequency of occurrence of the notes is greater than or equal to the aforementioned predetermined threshold frequency value.

In the example of figure 2 the cutoff frequency is set to at least 5 notes per second. The analysis file 1, run on stage, A10shows that there are seven notes tool No. 1, while only two notes exist for tool No. 32. In this case, the decision on the track, performed on the stage of A11may be to select track No. 1, despite the fact that priority 1 is set for tool No. 32, since the frequency of notes for instrument No. 32 is below a threshold frequency.

Parameters 2 can also include the number of synchronization signals, which must be issued. In the example of figure 1 this number was set to 1. Options 2 could also include criteria regarding the duration of the notes, such threshold value dlitelnosti this case, the analysis of the duration of notes for each instrument to an audio file, and selects the tool that has found a greater number of notes whose duration is exceeding a threshold duration. Another option could be the threshold of transition between two consecutive notes on the same track.

Finally, the signal SiSYNCH is created on stage, A12from the selected track. The signal may correspond to a sequence of pulses corresponding to each note selected track, or can be adapted according to the type of peripheral device that needs to be activated.

According to one of the possible embodiments of the invention, the above method may further comprise the step (A3determine whether the track synchronization in the above-mentioned synthetic audio file.

If the track synchronization is determined, the track synchronization can be automatically selected for forming the above-mentioned synchronization signal. Alternatively, it may be decided to choose another track, as a function of 2 parameters even if the track synchronization was found. Alternatively, can also be decided to choose the best path between any track synchronization or other extracted Dor is ICOI, selected as a function of 2 parameters. This last case corresponds to that shown in figure 1, where the step (A4gives an opportunity to choose the best path.

Figure 3 schematically shows a portion of a portable communication device, containing at least one media peripheral device (not shown), which can be activated in synchronism with at least one signal Sisynch synchronization, formed from synthetic audio file 1 stored in the memory device that implements the method according to the invention.
