Definitions

  • the present invention relates to a communication method and device, by subcarriers integrated into an analog or digital signal.
  • Certain communication systems operating by dedicated terrestrial line or by satellite have digital integration inside their original signal used for service signals for the remote control. In general this digital integration is inserted towards the end of the band of the original signal and consequently only admits a single subcarrier, taking into account the bandwidth.
  • DBR digital integration
  • FM radio Another communication system operating over the air (FM radio) also exists and is known as SCA.
  • SCA This system, in general, is integrated after the multiplexed signal of the analog channel, around 60 KHz. This subcarrier makes it possible to obtain an audio channel or digital information.
  • the object of the invention is to increase the number of transmissible subcarriers in an analog or digital signal and thus to increase the possibilities of transmission of said analog or digital signal. This goal is achieved for all modes of transmission, whether terrestrial or wireless, thanks to a specific process and device.
  • Method according to the invention as regards a modulator of subcarriers in source of emission and a demodulator of subcarriers in reception of the source of emission.
  • the digital and analog information to be transmitted on a single analog or digital signal are modulated into subcarriers by the modulator.
  • the modulator breaks down the original analog or digital signal into two different or identical frequency bands.
  • the modulator modulates two subcarriers for digital information or else a subcarrier in the audio channel in the second frequency band.
  • Identical frequency bands if you do not want quality audio support; in this case, the modulator modulates in each frequency band two subcarriers for digital information or else a subcarrier in the audio channel.
  • the modulator modulates in each frequency band two subcarriers for digital information or else a subcarrier in the audio channel.
  • a subcarrier demodulator Upon reception of said basic analog or digital signal, whether terrestrial or wireless, a subcarrier demodulator reshapes and distributes either two digital pieces of information or one audio channel, or four pieces of digital information or two tracks. Also at reception, the choice between digital information and the audio channels is made by an automatic command switching remote controlled from the transmission source by the subcarrier modulator.
  • a central management computer receiving its peripherals: image server, text server, digital advertising audio control, etc. for digital information; Sound control for quality audio support or for at least one audio channel.
  • This digital or analog information to be transmitted arrives at a subcarrier modulator comprising: - an 8 KHz filter for sending a quality audio source, bandwidth: 50 HZ ... 8 KHz. - A 4.5 KHz filter for sending an audio bandwidth channel: 50 Hz ... 4.5 KHz. - A subcarrier modulation for the next filter. - A 12 KHz filter for sending digital information. - A mixer mixing the 8 KHz and 12 KHz filters.
  • a receiver according to the type of reception desired, for example: a demodem for the reception of a dedicated line, a satellite receiver for the reception of a satellite, a receiver demodulated in frequency for the reception of a hertzian wave frequency modulated, ... - A sub-carrier demodulator output from the receiver and comprising: - An analog signal shaping. - An 8 KHz filter restoring the quality audio support. - A shaping of digital signals. - A 12 KHz filter restoring the digital information. - An amplifier of the preceding filter. - A subcarrier demodulator. - A 4.5 KHz filter with its de-emphasis and restoring the audiophonic channel. Note that the frequencies indicated for the filters are not fixed.
  • each digital item of information is connected to a digital addressing.
  • This digital addressing sends sixty-four digital information in deferred time and can, if it is coupled to a digital advertising audio system, define the time for the passage of specific audio messages.
  • the advantages of the device according to the invention are significant: - The possibility of being able to transport several digital or analog information on a single analog or digital signal, allows the user to considerably increase his communication possibilities. - The addition of digital addressing to the device also allows the user to be able to manage a very large number of messages and thus ensure almost all requests from customers in communication.
  • This product exactly meets an important demand of the communication market in audiovisual media: for example : Department store chains, cities, media, etc.
