Definitions

  • a method and system for acquiring and transmitting audience information for television programs is provided.
  • Each audience measurement or detection device comprises an internal clock, means for detecting the stopping and operation of the television set and for identifying the selected channel or channel.
  • each device is interrogated by a central unit generally during the night hours and via the switched telephone network.
  • the central unit in possession of the information provided by a certain number of devices, makes it possible to develop audience indices which are more or less exact, because the known devices do not make it possible to obtain information on the number of people watching a television program, or even knowing whether or not there is a spectator in front of the television set.
  • the present invention aims in particular to avoid these drawbacks. To this end, it proposes a method of acquiring and transmitting information on the audience of television programs, consisting of associating audience detection devices with television sets and / or video recorders to obtain information on the audience of television programs, to record this information and their precise dates in the memories of the devices and to periodically connect a centralization unit to each of these devices by the telephone network to transfer to this unit said information recorded in the devices, characterized in that it consists in connecting the centralization unit to the switched telephone network via a digital data transport network having access points on the switched telephone network, to use this network and its connection points '' as data concentrators between the detection devices and the centralization unit and, periodically or on instruction from the centralization unit, to connect all the detection devices or at least a large number of aux to the centralization unit and to transmit in real time to this unit the information detected by the devices on the television program audience.
  • the real-time transmission of the information collected by the detection devices makes it possible to immediately have data allowing the development of audience indices.
  • the use of a network such as the national TRANSPAC network and its access points makes it possible, very simply and without any particular investment, to very quickly obtain a very large amount of information from a large number of hearing detection devices distributed throughout the territory, and therefore to produce representative indices of the audience at the national level.
  • the TRANSPAC network is a national packet information transport network, dependent on the French Post and Telecommunications Administration.
  • this network is used by the TELETEL service to allow individuals with a video terminal to query one or more databases by first dialing the call number of a videotex access point at TRANSPAC network, then the access code to the targeted database.
  • Videotex access points are concentrators of terminals linked by the TRANSPAC network to an information processing system (server) associated with the database (s). The same system is used to establish connections and allow information to be exchanged between different terminals.
  • the information provided by hearing detection devices is not very large, it is possible to limit the TRANSPAC type network lines which will be used for transmission to the information centralization unit to a very small number. provided by a large number of detection devices. This number is for example 2, for a fleet of around 500 detection devices.
  • the method also consists in recording in memory in each detection device the call number of an access point to the transport network and an access code to the centralization unit, then having the dial automatically by the detection device, this call number and this access code, at a determined time recorded in memory in the device, and, after connection to the centralization unit and transmission of information, to disconnect the device of the transport network by means of an instruction given by the centralization unit.
  • the transmission lines established between the centralization unit and the detection devices can also be used to modify, from the centralization unit, an application program loaded in the detection device, and / or the parameters. acquisition of information, and / or keywords, access codes or the like also loaded into the device, as well as synchronizing the device's internal clock with that of the central unit and possibly ensuring maintenance or checking the operation of the device.
  • the information provided by the detection apparatus com take information relating to the shutdown and operation of the television set and the identity of the selected channel, and information on the number of people present in front of this television set.
  • All this information can be transmitted simultaneously to the central unit, with a delay in time on the corresponding event equal to a predetermined duration.
  • the information on the selected channel and that on the number of people present in front of the television set can be transmitted successively, with different delays compared to the corresponding event.
  • the invention also provides a system for acquiring and transmitting information on the audience of television programs, comprising audience detection devices associated with television sets and / or video recorders, a centralization unit for the processing of the information provided by these devices and of means for transmitting information between the devices and the centralization unit, via the telephone network, characterized in that each device comprises a microprocessor, information storage memories and a modulator circuit- demodulator for a connection to the switched telephone network, and in that the information transmission means comprise access points to the switched telephone network and lines of a digital data transport network, forming data concentrators and allowing transmission by a line of said network, information provided in real time by a large number of hearing detection devices.
  • the system essentially consists of audience measurement or detection devices 10 which are placed with selected people ("panelists") having at least one television set and possibly a video recorder. , which make up a representative sample of the national population, this in order to allow surveys on the audience of the various programs broadcast.
  • Each device 10 is therefore associated with a television set 12, to which a video recorder 14 can be connected.
  • Each device 10 comprises a modulator-demodulator (modem) circuit 16 for connection to the switched telephone network, a data processing unit 18 comprising a microprocessor and information storage memories, and circuits 20 for acquiring information on stopping and operating the television set, on the selected channel or channel and also on the operation of the video recorder, as well as, preferably, on the number of people present in front of the set 12 to watch a program.
  • the apparatus 10 also includes a clock, which may be that of the information processing unit 18, and which makes it possible to accurately date the audience information acquired by the circuit 20.
  • the apparatus 10 is connected to the switched telephone network 22 by a telephone line 24 of the quite conventional type, but different from the particular telephone line of the occupant of the premises.
  • a centralization unit 26, for example at the national level, is designed to be connected to the various apparatuses 10 via a national network 28 for transporting packet information, which will be called the TRANSPAC network for convenience.
  • the TRANSPAC network is made from the switched telephone network 22 by points 30 which are terminal concentrators and with which a telephone number, for example an abbreviated number, is associated.
  • points 30 which are terminal concentrators and with which a telephone number, for example an abbreviated number, is associated.
  • the centralization unit calls the apparatus 10 via the switched telephone network, by dialing the telephone number assigned to the telephone line 24; on receipt of the call, the device 10 connects to the centralization unit 26 via the circuit 16, the line 24, an access point 30 and a TRANSPAC line.
  • the centralization unit 26 can then load a new application program in the memory of the processing unit 18 of the device 10, program an automatic call time, a call number, load into the memory of the unit 18 information acquisition parameters or modify the values of these parameters, synchronize the clock of the device 10 with that of the central unit 26 and also, in a conventional manner, have access to the memory of the unit 18 of the device 10 and transfer its content to the centralization unit 16.
  • the processing unit 18 of the device 10 can, via the modulator-demodulator circuit 16, call the centralization unit 26 at a predetermined (programmed) time, automatically dialing the number of a point 30, then the access code of the centralization unit 26.
  • the centralization unit 26 can have access to the content of the memory of the unit 18 and therefore recover the recorded information before the connection, and remain connected to the device 10 to receive in real time and progressively the audience information which is provided by the device, on the stopping or the operation of the television set 12, the channel selection, possible operation of the video recorder, and the number of people present in front of the station.
  • the information collected by the apparatus 10 is generally checked or checked before being transmitted. For example, after a channel change, it is desirable to wait a few seconds before transmitting the information to check that it does not change in the meantime.
  • the channel change information is therefore transmitted with a predetermined delay of between 2 and 10 seconds for example, the value of which can be modified at will.
  • Information on the number of people present in front of the television set is transmitted with a greater delay, for example of the order of 10 seconds to 1 or 2 minutes, allows both on the one hand to control the information itself and on the other hand to take into account certain transient situations such as the movement of a person, his passage in front of another person, etc ...
  • the information on the selected channel and the number of people present, corresponding to the same event, are therefore not simultaneously ready to be transmitted by the device 10. It is therefore possible, either to delay the information of selected channel compared to the information of people present to transmit these two types of information simultaneously, with the same known and predetermined delay of for example 30 seconds, or to transmit them one after the other, that is to say the information of channels selected as soon as they are available, then information on the number of people present as soon as they are available. It may indeed prove to be advantageous to have the information of selected channels almost immediately available to very quickly give a first trend at the national level, then to refine this estimate within 30 seconds or the following minute.
  • the transmission of information between the apparatuses 10 and the centralization unit 26 requires a very small number of access lines to the TRANSPAC network on the centralization unit.
  • Each of these lines has for example a transmission capacity of 19,200 baud, which makes it possible, taking into account the small volume of information transmitted in real time by a device 10, to manage the transmission of information provided by approximately 250 devices.
  • Two lines are sufficient, for example, for the real-time transmission of information supplied by 500 devices simultaneously connected to the centralization unit 26.
  • the cost of installing the system according to the invention is particularly reduced.
  • the devices are disconnected from the TRANSPAC network on receipt of a particular order issued by the centralization unit 26.
  • the information collected by these devices is then stored in the memories of the processing units 18, to be retransmitted to the centralization unit 26, either in response to a call from the latter, or automatically at the next scheduled call time by the devices 10.
  • the direct connection lines, via the switched telephone network, between the centralization unit 26 and the devices 10 are only used for the initial loading of an application program into the memories of the units 18 of the devices 10 or for a modification of this program or of the parameters for acquiring information, and maintenance or verification of the correct functioning of the devices 10.
