Abstract

Single multi-wave transmission device for listening on a DTT receiver to digital broadcasts transmitted over the Internet. The object of the present invention is to enable all users having an RNT (RH) receiver to listen as simply and by the same usual manipulations on said RNT (RH) receiver to all the digital radio broadcasts (EN) transmitted by Internet radio stations (RN). The device of the invention consists of a small "transcoder box" (TC) integrated or attached to an RNT receiver (RH) which differs from the previous methods and in particular from the patent previously filed by the same author, by the fact that it Does not emit carrier waves modulated in Fm, but carrier waves of compressed digital signals, depending on the mode and at the frequencies of the RNT, and intended to be received by an RNT receiver. Digital radios (EN) are chosen by the user on a specific website (ST) using a computer (OD) or other IT medium. The selection of free analog frequencies (FL), their association and the transmission of analog waves to the RNT receiver (RH) are carried out by the "transcoder box" (TC).

Description

Multi-channel single emission device for listening on a TERRESTRIAL DIGITAL RADIO receiver to digital broadcasts transmitted over the Internet.

We know that there are several modes of broadcasting radio programs including, for example, hertzian analogue radio, the most widely used up to now, and the more recent and growing digital radio.

Most of the radio stations listened to on a static receiver, for example of the Hi-Fi system type or on a mobile receiver, for example of the car radio type, are to date transmitted by analogue terrestrial broadcasting in frequency modulation.
that is to say on the FM band and require to be perceived a radio receiver adapted to this mode of transmission as well as an FM antenna.

In addition to this hertzian analog transmission, where the sound in the form of an electrical signal is transported as it is in the carrier wave, there is today another mode of transmission, called digital terrestrial radio, which is intended for reception by a other type of radio receivers. Here, the sound is first digitized and then compressed using various techniques in order to be transmitted while optimizing the bandwidth. The frequency of the carrier waves is located in a spectrum far from that of the FM band, digital radio keeping the principle of a frequency allocated to one or more radio channels. To be captured and decoded, it requires specific equipment (digital radio station). These digital radios are enjoying increasing commercial success, in the case of static as well as dynamic use; many cars are now equipped with it.

As this digital broadcasting mode has progressed rapidly in recent years, we can now be sure that the 2 transmission / reception modes, namely conventional hertzian FM radio and digital radio will coexist for many years to come. This patent only deals with the device specific to digital radio, which we will call hereinafter RNT, the device specific to FM transmission / reception which has been the subject of a previous patent filing by the same author.

Unlike analog over-the-air FM radio where sound is emitted as a signal carried as it is in a carrier wave, digital broadcasting emits sound that is first digitized and then compressed for transmission by optimizing bandwidth.

Digital broadcasting can use two transmission modes: Transmission via the Internet network or via the terrestrial network known as RNT.

Digital radio broadcast over the Internet can currently be received in a
private or public place, on a fixed or laptop computer, a pocket terminal for example a smartphone, a tablet or any other suitable receiver.

If today it is possible to listen to at home or in a public place, on different media all the radio stations broadcast over the internet, it is essential for the listener to first download the application of the radio station (s). desired or a specific multi-station application. In addition, listening to these media most often poses quality problems, these media such as: computer, smartphone or tablet not being equipped with a high-performance audio function.

For these reasons, some users resort to connecting the medium to a quality digital radio receiver, in particular a Hi-Fi system or other, by means of an auxiliary or Bluetooth socket reserving partial or total use of this former medium. exclusively for this application alone, prohibiting or hindering any other function. In addition, this function is energy intensive and penalizes the autonomy of the support.

Already aware of the difficulties experienced by expatriate motorists in receiving radio broadcasts emitted in their country of origin, motorists traveling abroad to continue to perceive the emissions emitted by the territories previously visited or even motorists too away from the FM transmitters of the stations they wish to listen to, as well as by the serious safety problems posed by the use of a smartphone while driving, the author of the present invention had already been led to file a patent concerning a device complementary to the standard radiophonic installation existing in a motor vehicle,.

The characteristics of use of the device of this patent are identical to those described in the preceding patent, but are specific and dedicated to Digital Terrestrial Radio and no longer to FM radio.

The author of the present invention therefore imagined a complementary device to an existing radio installation, to allow any listener equipped to perceive on his digital reception system (for example a HI-FI system or a car radio), all the radio broadcasts. on the internet around the world, as he usually perceives a radio station received in the traditional way by his digital receiver.

Advantageously, a French resident temporarily in foreign territory can listen on his digital receiver, without the slightest difficulty, under the same conditions and following the same manipulations, all the broadcasts from French radio stations.

Thus, the "device by single multi-wave emission for listening on an RNT receiver, digital broadcasts transmitted by the Internet" differs from the device of the patent previously filed by the same author, in that the waves emitted by the device are intended to be received by an RNT receiver and no longer a receiver
FM

The device of this invention consists of a “transcoder box” supplied with 12 volts in mobile applications and in particular in a motor vehicle or with 220 volts in static applications in a private or public space, associated or linked functionally, for example, to a device. static RNT receiver placed in a private or public space, to receive the digital signals of radio broadcasts from all over the world via the Internet, transform them into low-power hertzian analog signals with the characteristics of RNT receivers and send them to said receiver RNT so that the listener can perceive on it and in the same way that he does it for the reception of the radio stations transmitting locally in, all the digital transmissions transmitted on the Internet network.

Contrary to all the patents of the state of the art prior to the patents of the author, the present invention aims to allow any listener to listen from an RNT receiver and in addition to the radio stations transmitted locally on the RNT network on the territory where it is located, the digital radio stations transmitted over the Internet that it will itself have selected from among the thousands of stations transmitting on this network, by first configuring the "transcoder box",

Advantageously, a French resident will be able to select an Australian radio station on his RNT fixed receiver, an African resident will be able to select and listen to a French radio station on his RNT fixed equipment, under the same conditions and with the same interventions on his RNT receiver as s' he would select a radio station broadcast in the territory in which he is located. This also induces
identical and satisfactory handling conditions, insofar as they are carried out in the same way when listening to conventional stations transmitted locally.
