With automatic content recognition (ACR) technology embedded in tens of millions of smart TVs, TV chipsets, mobile apps, gaming consoles, streaming devices and OTT services, Alphonso understands what programming and advertising people are watching on TV.
With your permission provided at the time of downloading the app, the ACR software receives short duration audio samples from the microphone on your device. Access to the microphone is allowed only with your consent, and the audio samples do not leave your device but are instead hashed into digital “audio signatures.” The audio signatures are compared to commercial content that is playing on your television, including content from set-top-boxes, media players, gaming consoles, broadcast, or another video source (e.g., TV shows, streaming programs, advertisements, etc.). If a match is found, Alphonso may use that information to deliver more relevant ads to your mobile device. The ACR software matches only against known, commercial audio content and does not recognize or understand human conversations or other sounds.
