DESCRIPTION

ad remover device

TECHNIQUE SECTOR

This application refers to an ad removal device that comprises a television signal receiver, such as a television or a system connected by Internet to a television network or program repositories, whether live or pre-recorded or pre-recorded. issued.

STATE OF THE ART

The use of televisions and other display devices for viewing television programs is known in the art. These programs are generally broadcast free-to-air, so that anyone can watch them, and in return they include advertisements or advertising space.

Frequently, and contrary to numerous regulations, the advertising space is broadcast with a higher tone to attract attention, and ensure that the viewer is attentive to it. At other times, it just annoys the viewer. Therefore, it is desirable to reduce this effect. Application U202231014, from the same applicant, is known, offering a solution. In it, the system detects the increase in volume or other factors to recognize when the television broadcasts advertisements and replace the audio, the image or both.

However, this system can jump in moments of greater tension, where the program itself turns up the volume. So, you can change the image at the moment of greatest interest in the movie or program.

However, television programs are broadcast with an attached signal in the audio module parallel to the main one, this being of low frequency (frequently 6-8 Hz) that identifies its type for audience analysis and other services.

The Applicant is not aware of any solution to these problems similar to the invention.

The invention relates to an advertisement remover device according to the claims, which embodiments improve and solve the problems of the art.

The ad removal device comprises a control unit, a screen, a sound module, a module for receiving an audiovisual signal to be broadcast on the screen, and the sound module. The control unit is configured to detect the emission of an announcement and to replace at least the audio signal with a signal stored in internal or external memory. Ideally it also replaces the image or video signal. Unlike the state of the art, it performs an analysis of low-frequency emissions, inaudible to the human ear, to detect these advertisements. The analysis can be complemented with the methods of the state of the art in case the television broadcaster does not adequately comply with the legislation.

Other variants are appreciated in the rest of the report.

DESCRIPTION OF THE FIGURES

For a better understanding of the invention, the following figure is included.

MODES OF CARRYING OUT THE INVENTION

An embodiment of the invention is briefly described below, as an illustrative and non-limiting example thereof.

Figure 1 shows the scheme of an embodiment according to the state of the art and known from the cited document U202231014. It consists of a screen (1) with a signal reception module (2), either an antenna or an Internet communication system or similar. This reception module (2) is configured to receive audiovisual signals to broadcast on the screen (1). The screen (1) is complemented by a sound module (3), such as speakers or a bluetooth system or similar to send the audio to external speakers or headphones. A control unit (4) receives the signal, sends it to the screen (1) and analyzes it to detect the start and end of advertising spaces. Unlike the state of the art, the unit control is set to use the low frequency audio signal (typically 6-8Hz) to recognize the type of program.

In the cited state of the art, the onset can be detected by a sustained rise in volume over a period of time. This solution can complete the current invention, so that the signal at low frequency improves the reliability. If the program is a movie, the increase in volume can be a moment of tension, while in a news program it is not expected. So if the TV station doesn't coordinate the low-frequency signal change with the broadcast, the device can still detect them.

When the control unit (4) detects the presence of an advertisement or advertising space, it takes an audio signal from a memory (5), such as an internal memory, a place in the cloud, an external memory connected to the device. This audio signal is preferably music, but can be a live or recorded radio program (podcast).

The internet connection allows the device to receive updates or information from a central server. For example, the central server can monitor the main chains and notify them when they start broadcasting advertising. It can also save ads in memory, either detected by a technician or by an artificial intelligence system that recognizes the repetition of the same audio and/or video pattern in different channels.

In this way, when the viewer is watching your program and it enters advertising, the sound is replaced by a piece of music or radio that he has selected and, possibly, stored in memory. The interruption ends when the control unit (4) detects the end of the advertisements or advertising space.

Likewise, the video signal can be modified so that it stops showing the signal with the advertisements or advertising spaces and emits a video selected by the user or shows the blank screen. Thus, in one solution, the control unit (4) will display YouTube videos or the like instead of advertising spaces. The received video signal can be displayed in a box to give the user confidence that the device is not causing them to lose any of their program. You can also include a remote control to deactivate the device if it detects an advertisement of your interest.

One embodiment of the device comprises the control unit (4) that deals with detecting advertising spaces, a signal reception module (2), either direct or through the television, which ideally includes the Internet communication system and , optionally, the antenna, and a standardized connector to be fixed to the television: euroconnectors, USB, HDMI, coaxial... in a detachable way. In this case, the screen (1) and the sound module (3) can correspond to a television, for example, which does not need to be intelligent. This form can have the memory (5) or use the communication with the internet to recover the substitute audio.

The device can be controlled by a remote control, a mobile phone application or a voice command receiver.
