  • One field of application of the present invention is in particular the area of the classification of music titles that are broadcast or played in a large number of public places, in particular in discotheques.
  • this existing system has a number of disadvantages, in particular with regard to reliability and with regard to the speed of transmission and evaluation.
  • the implementation of the registration described above requires the involvement of people, i.e. that of the entertainer or disc jockey, which necessarily entails various coincidences and risks if the entertainer or disc jockey mentioned carries out the various duties and tasks imposed in the minutely.
  • people i.e. that of the entertainer or disc jockey
  • the registered titles do not match the ones actually played in the selected discotheques (forgery, prior recording of the titles before the corresponding evening event, etc.) or a shift in the actual recording in terms of the date or the predetermined or specified times.
  • the present invention is therefore based on the object of eliminating all of the disadvantages mentioned.
  • your object is a device for recording and transmitting sound or audio signals for the purpose of their identification and is characterized in that it essentially consists of the following.
  • Part of a large number of local recording modules, each of which is composed of circuits for processing and digitally converting audio signals, of circuits for digital storage with large storage capacity and of circuits for analogue conversion and for connection by means of at least one line of a telephone network is and on the other hand part of one or more units / units for evaluation and control, which controls the function of the various local recording modules and centralizes the data that centralizes the audio signals that come from the former by means of the telephone network.
  • the invention further relates to an automatic or semi-automatic method for recording, transmitting and evaluating sound or audio signals which have been collected simultaneously or non-simultaneously at different predetermined locations and is characterized in that at least one group is configured and configured of units of local recording modules from one point in time and for a predetermined period of time, simultaneously or non-simultaneously, a sample of the sound or audio signals, which are produced at different locations in accordance with selected local recording modules, is taken and stored, that the signals mentioned, stored in the various selected modules, are then transmitted to an evaluation and control unit by means of a telephone network, that said recorded sound or audio signals are identified and the frequency of occurrence of each different unit of the sound signal is determined depending on the selected different locations according to the local recording modules and that, as required, the above-mentioned steps are finally repeated at regular intervals, for example once a day, in each case a new selection of affected local recording modules being carried out beforehand.
  • This device essentially consists, as the drawing mentioned shows, in part of a plurality of local recording modules 1, each of which is essentially composed of circuits 2, 3, 4, which carry out a treatment and digital conversion of the audio signals, and from digital storage circuits 5 with large capacity and from circuits 6, 7 for analog conversion and for connecting at least one line of a telephone network 8 and the other part of one or more units 9 for evaluation and control, which controls the operation of the various local recording modules 1 and the data corresponding to the audio signals, which are issued by the latter, centralized, namely by means of the telephone network 8.
  • each local recording module 1 contains on the one hand a programmable processing unit 10, in particular in the form of a microcontroller or a microprocessor with a memory 10 'and a timer or clock generator 10' ', which controls all of the circuits 2 to 7 and their communication with the central evaluation unit and, on the other hand, a power supply unit 11 which, if necessary, is connected to an autonomous emergency power supply in order to ensure the function of the local recording module 1 even if the public power supply fails and, in particular, to carry out the transfer of the stored data or to complete it completely.
  • a programmable processing unit 10 in particular in the form of a microcontroller or a microprocessor with a memory 10 'and a timer or clock generator 10' ', which controls all of the circuits 2 to 7 and their communication with the central evaluation unit and, on the other hand, a power supply unit 11 which, if necessary, is connected to an autonomous emergency power supply in order to ensure the function of the local recording module 1 even if the public power supply fails and,
  • the circuits for processing and digitally converting the audio signals can advantageously consist of a filter circuit 2, which is connected to an input 12 for audio signals and a correction, in particular a reduction in the pass band of the audio Signals carried out and from an automatic gain correction circuit 3 and a unit 4 for sampling and analog / digital conversion with great dynamics, the numerical or digital data at the output are then stored in the memory circuit 5.
  • the circuit 6 for analog conversion which is connected to the outputs of the memory circuit 5 or the digital memory, consists of a digital / analog converter which operates at a frequency which is clearly above that of the circuit 4 for digital conversion of the Audio signals lies and thus also delivers an audio signal based on the stored digital data, which is compressed with respect to the digitized audio signal obtained during the recording phase.
  • the circuit 7 for the connection consists of a telephone line interface which contains a unit 7 'for the transmission of analog signals which are supplied from the digital / analog converter 6 and a part 7' 'which is a modulator / demodulator 13 contains, for the digital exchange of information between the processing unit 10 'of the local recording module in question and the unit (s) 9 for evaluation and control, starting with the phase of configuration and parameterization of said module 1 by said unit / Units for evaluation 9 and at the beginning and at the end of the transmission phase for the stored data in the memory circuit 5, which correspond to the extracted and stored audio signals.
  • the entirety of the circuits 2 to 7 and the units 10 and 11 of each local recording module 1 is arranged on one or more printed circuit board cards, which are in a closed fixed container 14 is housed, which is provided if necessary with a seal, a power supply cable 15, a line 12 'or a connecting element for the inlet of the audio signals, which are supplied in particular from a mixer to a discotheque, a line 16 or a Telephone connection and a line or a connecting element 17 for the bidirectional transmission of digital data are provided in accordance with the configuration and parameterization of the processing unit 10 of the local recording module 1.
  • the number of local recording modules is relatively important, for example in the case of nationwide use and the transmission of the recorded signals by the selected modules 1 within the range of reduced telephone tariffs of the telephone network 8 to a single evaluation unit 9, it can be advantageous to to provide a plurality of evaluation and control units 9, each of which is assigned to a defined group of local recording modules which are individually identified by their respective telephone numbers, the local recording modules belonging to a group being able to be changed or exchanged depending on a random number or regulated selection during the phase of recording and transmission according to the following.
  • Each evaluation and control unit 9 is preferably in the form of an information unit with a memory 18 of very large capacity and is assigned on the one hand to a telephone connection circuit 19 which is connected in particular to a preselection converter which carries out a new selection of the local recording modules concerned and on the other hand a unit 20 for converting and restoring the compressed audio signals into an understandable sound form, these audio signals coming from various queried local recording modules 1, which are connected by means of the telephone network 8 to the respective evaluation and control unit 9.
  • a telephone number is assigned to each local recording module and the establishment of a telephone connection between the central evaluation and control unit 9 and a specific local recording module 1 is reserved exclusively for a specific central evaluation unit 9, any communication between the latter and a specific recording module 1 begins with a mutual identification protocol and a description of the Transmission type and the type of data to be transmitted (numerical data; parameterization of the processing unit 10, programming, control data of the state of the module 1 in question; analog data; sound or audio signals that are stored in the module 1).
  • each local recording module which originate, for example, from the mixer 21 or an amplifier of a sound system in a discotheque, are treated with regard to their passband and their amplitude as a function of the mean energy, then digitized and stored in adapted electronic memories 5 and, finally read from these memories 5 at the request of a central evaluation and control unit 9, converted into analog signals at a frequency which is higher than the frequency used in the digitization and in analog form by means of the telephone network 8 and the corresponding central collecting unit 9.
  • a limited section of a tone sequence or a sound unit e.g. a piece of music, a song or the like is sufficient to identify it.
  • the local recording modules In order to adapt the recording duration to the size or capacity of the existing memory circuits 5, provision can be made for the local recording modules to intermittently extract and record the sound or audio signals, for example in successive continuous sequences of one minute each, which are more equivalent due to time intervals Are interrupted during which no withdrawal takes place.
  • This provides a reliable device and method which is adaptable to use and is not subject to human malfunctions, which has no wear on mechanical parts and no delay in transmission.
  • an analog audio signal is continuously fed via line 12 'to the input 12 of the module 1, which is reduced in its frequency band by the filter 2 and dynamically limited by the gain controller 3 .
  • the circuit 4 takes a sample from this frequency and dynamically limited analog signal at predetermined intervals, which takes place under the control of the microprocessor 10. Furthermore, the sample taken is converted into digital signals by an analog / digital converter contained in the circuit 4 and is likewise stored in the memory 5 under the control of the microprocessor 10.
  • the memory therefore contains digitized data of short samples of audio signals.
  • a telephone connection between these two units is established via the telephone network 8 to which the control unit 9 and the module 1 are connected.
