what is its disadvantage
What is ACR
ACR ie Automatic Content Recognition is a technology that is used to monitor the content playing on your TV. Simply put, ACR identifies movies and shows that can be played on a media device. He sees which streaming box or OTT apps you use. Also, what kind of movies and shows are watched, then ACR sells this data to marketing companies. With this, marketing companies target you for the same type of advertisement as the type of content you see. For this ACR does not have to do any separate effort. This technology is completely dependent on user-based input or search, which issues ads according to the shows playing on your screen.
how to defend
If you do not want marketing companies to access your personal data, you must deactivate ACR. Different smart TVs have the option to turn off ACR in different ways. But if we talk about Samsung TV, then first you have to go to the Smart Hub menu. After this you have to visit the setting option. Then click on the Support option. After this, click on the Terms & Policy option. After this you will get the option of Sync Plus and Marketing. Which has to be disabled. If you are setting up a new Smart TV, you will be able to turn off ACR by going to Terms and Conditions.
