Roku scares me when I'm watching movies on my Rapsberry Pi. They are .mp4 files. I'm not using their software at all... and about 2 minutes in I get a pop-up "You can view this move elsewhere at XYZ." How do they know what movie I'm watching? They are analyzing the feed. Scary.

- sintaxi 7y agoMy guess would be the distribution companies provide them a hash table of MD5s that maps popular torrents to places where they can be purchased. The company that makes the TV sells this services to the distribution company and/or gets a cut of the sales. Furthermore, it probably logs the IP of the person watching the pirated file and sells that data also.

- GhostVII 7y agoI think they are just fingerprinting the video and audio. They shouldn't have access to the actual file that is being played if you are just connecting the TV to the raspberry pi. I think I saw another thread where someone from Roku confirmed this (I had the same thing happen and it annoyed me so I looked it up).
- unwiredben 7y agoThis is the ACR technology in Roku TV devices. It works on the TVs inputs and fingerprints the video several times a minute, sending thumbnails to a server to get visual matches. To disable, go to Settings/Privacy/Smart TV experience and turn off the "use my TV inputs" option.
