Description

INTERNAL STORAGE MEDIUM FOR RADIORECEIVERS WITH HARDWARE MEDIA ADAPTED TO AUTOMATICALLY SEARCH MUSICAL SONGS The present invention refers to an internal storage medium for radio receivers with hardware medium suitable for the automatic search for musical pieces. For this operation, the use of a radio receiver has been known for some time and is inefficient. In particular, it is not possible to record and reproduce a radio program on air without resorting to an external recording and storage medium. This can cause various problems, such as poor audio quality, ineffectiveness, and unreliability. Object of the present invention is providing a system which does not have the drawbacks of the aforementioned classical systems and which is particularly simple and convenient. Another object of the invention is providing a system having a structure that is easy to make. These and other ob j ect s are achieved according to the present invention by means of an internal storage medium for electronic devices which allow to receive radio waves .

The above and other ob j ect s and advantages of the invention, as will emerge f rom the following description, are achieved with an internal storage medium for radio receivers such as that described in claim 1 . Preferred embodiment s and non-trivial variant s of the present invention form the sub j ect matter of the dependent claims .

It is understood that all the attached claims form an integral part of the present description .

It will be immediately obvious that innumerable variations and modifications ( for example relating to shape , dimensions , arrangement s and part s with equivalent functionality) can be made to what is described without departing from the scope of the invention as appears from the attached claims .

The present invention will be better described by some preferred embodiment s , provided by way of non-limiting example , with reference to the attached drawings , in which Figure 1 shows a schematic view of an embodiment of the internal storage medium for radio receivers according to the present invention.

The object of the present invention is located in the electronic and telecommunications sector and refers to an internal storage medium 1 for electronic devices which allow to receive radio waves, with the aim of recording and reproducing the decoded analog and digital information coming from a antenna (radio program) 5.

In its embodiment, the device comprises an internal hard disk or a similar type of mass memory device and a hardware device suitable for the automatic search for music tracks.

Referring to FIG. 1, it can be noted that the internal storage medium 1 for radio receivers comprises a magnetic mass memory device 3 which uses one or more magnetized disks (Hard Disk) or a similar type of mass memory device for the storage of the decoded data (recording of a radio program) coming from a receiving device 4 equipped with an antenna 5, and subsequently sent to the acoustic diffuser device 7 for the reception of the transduced electrical signal, which in turn also includes a RAM device 9, which in fact indicates a temporary memory area (Cache) , to store a set of decoded data (radio waves) 3, coming from the receiving device 4 and then subsequently sent to the acoustic diffuser device 7 for receiving the transduced electrical signal, data that can be retrieved later, when necessary (feedback) , for a numer or indefinite of times, in such a way as to allow the rewind or fast forward of a recorded radio program, or pause and resume playback of a program while it is still on air.

Advantageously, the aforementioned medium 1 in addition to the closest known art (described in patents n. NA2014U000021 and NA2014U000028 ) , also comprises a hardware device 11 suitable for receiving (in real time) certain radio frequencies.

In particular, the hardware device 11 consists of a dedicated software based on musical identification to capture a short sample of a piece of music (song) being played (by recognizing a sequence of bits) , on a radio station other than that listening to the user.

A fingerprint is then created (sequence of bits or based on some of the fulcrums of the simplified spectrogram and the target area between them) on the basis of the sample, and it is compared with a central database (constituted by the mas s storage device 3 reference containing an archive of standard digitized samples ) designed to search for the similarity between a piece of music played and those set by the user in a certain " favorite" digital channel selected remotely or in any case on the screen using a display .

Furthermore , the fulcrums of the simplified spectrogram, for each point in the target area, create a value which is the combination of the frequency at which the anchor point is located, the frequency at which the point in the "target zone" is located and the time dif ference between the point in target zone and when the anchor point is in the song .

Advantageously, the user select s / set s a series of favorite music tracks ; meanwhile , the user can : listen to a piece of music or a radio program broadcast on a specific radio station .

I f , in the meantime , a match is found between a favorite song selected/ set by the user and a song playing on a dif ferent radio station ( from the radio station the customer is listening to at that time ) , then on a user display the radio station being played and pos sibly the information about the artist and obviously the title and the lyrics of the song are shown.

In addition, the user can decide to accept to automatically switch to the aforementioned radio station to listen to the song.

Finally, the user can alternatively decide to record the song even without listening to it immediately according to the process already explained .

The technical solution can be applied in different areas:

- stereo systems, preferably including "car radios " ;

- televisions using some radio channels; and is applicable for both analog and digital channels .

In the case of an analog channel, the hardware device 11 is provided with a transducer (or a set of transducers) which transform the electrical signal into a sequence of bits (by means of an internal analog-digital conversion) as regards the technical solution described above, but also with regard to saving a song in the mass memory.

Unlike the well-known "SHAZAM", in this case the vocal/musical notes are not recognized through the necessary use of an acoustic device, but are recognized through a hardware device 11 which analyzes all the telecommunication signals coming from the radio stations and compare with a central database .

The reference hardware device 11 is a set of tuners and radio receivers, to simultaneously collect the transmission information from all the radio stations, so as to be able to achieve the objectives proposed above.

The tuner is already well known to those skilled in the art. In this case, the hardware device 11 brings together several tuners.

The tuner is the set of circuitry that receives radio frequency (RF) transmissions - such as radio transmissions - and converts the selected carrier frequency and its associated band into a fixed frequency, suitable for subsequent processing; this is because a lower frequency is typically used for the output. FM/AM broadcast broadcasts usually use this intermediate frequency (IF) directly on a demodulator which converts the radio signal into an audio-frequency signal which is then passed to an amplifier connected to the loudspeaker. In the case of more complex broadcasts such as PAL/NTSC (for analog TV) , DVB-T/DVB-S/DVB-C (for digital TV) , a higher bandwidth is used, usually with different sub-carriers. These are transmitted inside the receiver as an intermediate frequency. The next step is generally either to process the sub-carriers as real radio transmissions or to sample the entire band with an analog-to-digital converter with a sampling rate greater than the Nyquist rate, i.e. at least twice the intermediate frequency. The term tuner (or tuner) can also refer to a radio receiver or a separate audio component that is part of an audio system that can be connected to a separate amplifier. The verb "tune", in radio contexts, has the meaning of setting the desired carrier frequency on the receiver that is used by a specific radio station for transmission.
