All modern smart TVs are continuously sent to the manufacturer information about what the user is looking. I found item, allowing it in the settings of your TV.
The Washington Post using IoT Inspector program from Princeton University studied the traffic of four major manufacturers of television sets and found that TV continuously sent casts of screenshots of what the user is looking (this ethereal image, and that the conclusions on the Smart TV application screen, and the signal from HDMI-input).
For example, the Samsung TV every 2-4 minutes sends the packet to samsungacr.com site.
ACR - Automatic Content Recognition - system that recognizes viewed content (just as Shazam recognizes music). For her work quite two dozen small pieces of the image, which transmits TV.
For each user, the system creates a log viewing different content. This data is TV manufacturers can use to display targeted advertising, and may sell them to other companies. Thus, the American manufacturer Vizio sells such data about thirty companies.
While it's pretty harmless, but no one bothers to start using the ACR for fixing the viewing forbidden content, and you can check if the user has rights to view content and start viewing punish piracy content.
I think many of you will be surprised with the fact that the manufacturer of your TV knows what you're watching on your TV, giving him a signal from a computer or media player.
Of course, such a thing is illegal to do without the user's consent, that's just about everything users have given such consent when taking the license agreement when you first start TV.
Many TV transmission of information on content being viewed can be disabled. So, my Samsung 40MU6400 corresponding item (it is on the title picture) is hidden deep in the Settings-menu Terms and politics - viewing information services. Somehow, everything is written without spaces.
I certainly tick removed, it is hoped that this really is no longer transmitted information about the image on the screen. If you SmartTV, look like a tick and remove it if you do not want to tell your TV manufacturer, when and what you watch.
