The Arduino based “word blocker” for TVs

It’s interesting to see this make the rounds, everyone wants this as a feature in their TVs, but it will never happen, it’s like a spam blacklist for brains. So Matt built his own…

I don’t know about you, but I’m a little sick of hearing about the same people on TV over and over again. I came up with this Arduino-based solution to mute my TV so that I don’t have to hear about Donald Trump’s feud with whomever or Charlie Sheen’s most recent rant. Using the Video Experimenter Shield, the Arduino is able to decode the closed captioning transcription track, which is transmitted along with the NTSC picture signal. The incoming text is processed for a set of keywords such as “KARDASHIAN” or “SNOOKI” and sends my television’s IR remote control mute command, muting the TV for 30 seconds and then unmuting it (as long as a keyword isn’t mentioned again).
