Description

FIELD OF THE INVENTION The present invention relates to a device for identifying a television channel by means of an audimeter. The invention finds a particularly advantageous application in the field of audimetry, that is to say for the measurement of audience. State of the art In order to measure the audiences of a television channel, it is essential to be able to identify at any time, for statistical purposes, the television channels watched by a panel of viewers. For this purpose, there are several solutions to identify the reading of a television channel by a viewer. One known technique is to use the sound signal of the system to incorporate an inaudible signal for the viewer to encode a string identifier. This sound signal can be picked up by an analyzer coupled with the television and retransmitted to a audimeter which performs the decoding of the sound signal to extract the identifier of the channel to analyze in real time the channel watched by the viewer.

Another technique is to use the frame return lines, which are free of image signal, to broadcast digital data such as teletext information or service information which may include including a string identifier, as provided. by various national and international standards such as Didon, Ceefax, VPS or PDC. This service information can be detected at the television, for example by a method as described in European Patent No. EP 0 830 028. The channel identifier is then transmitted to a meter which analyzes in real time the channel watched by the viewer. The meter is connected to a remote server via a wired Internet connection, WiFi or GSM. The server receives the television channels watched over time by a panel of viewers and estimates the audience of the television channels. In addition to the detection of the television channel observed, the analyzer must also transmit the electrical state of the television: on or off.

The detection modules of this electrical state may have malfunctions for plasma screens, for LCD screens with an external transformer and for televisions equipped with a presence alarm triggered by the update of the television. However, the sensitivity of electrical detection and greatly reduced. When the televisions are in economic mode this sensitivity disrupts the measurement of the state of the television and the measurement of audience and affected because the audimeter turns on and off more times for no reason. During the installation of the device, a technician must adjust a probe of the electrical state following a particularly rigorous procedure. The television must have the lowest possible consumption: black screen, minimum contrast, minimum luminance ... In this configuration, the technician switches to the detection threshold setting. The problem with this device is that current televisions consume very little and it becomes very difficult to correctly set the threshold during the first pass of the technician. Several passes of the technician are necessary for a correct setting of the probe. In addition, current TVs have a daily update to 3H to 5H in the morning. When updating the television, electronic parts of the television can be powered independently of the screen. Consequently, if the probe threshold is incorrectly set, the audimeter turns on and asks the panelist to declare his presence by means of a beep that can last for the duration of the update, ie to say about 3min. This detection error can therefore be very annoying for the panelist. These known devices are made by a first housing performing the analyzer function coupled to the television and a second housing performing the function of the audimeter. The decoding of the identifier of the chain can be performed independently on the first or the second housing. The two boxes can be distant from a distance of 1.8m for reasons of space and they are conventionally connected by a USB cable transmitting the signal to be decoded or the channel identifier and the state of the television. In addition, each housing must be electrically powered independently because of the distance between them.

Thus, existing solutions generate a large footprint in the son of connections and power of the two housings, the display, the cable of the analog audio signal and if necessary digital sound recording a digital / analog converter must be installed. The number of connectors has a negative impact on the installation time of the identification device which can vary between one hour and one hour and thirty minutes depending on the type of television. The reduction in the size of television sets also limits the possibilities of installing current devices due to lack of space, especially for wall mounted TVs. In addition, when the television is replaced, the current devices generally require a complete reinstallation of the system with the intervention of a specialized technician. DISCLOSURE OF THE INVENTION The present invention aims at remedying the disadvantages of the prior art by proposing a device for identifying a television channel in which the analyzer is powered directly by the television and comprises wireless communication means. so as to communicate wirelessly with the audimeter connected to a wireless receiver.
