Sony Electronics in Park Ridge, New Jersey, and its Tokyo parent are jointly patenting technology for a TV, set-top box or DVR that suppresses broadcast or recorded TV commercials and claims to do so much more effectively than current systems. Sony’s system, described in U.S. application 2014/0064705 filed in November 2013, names Brant Candelore of San Diego as the inventor. “Most every business entity advertises to promote products or services, and often pays significant sums of money on such activities to broadcasters and service providers,” said the patent. But consumers “are generally less entertained by advertising,” it said. “To most, an advertisement is an unwanted pause in a program with generally increased volume, and therefore, a significant inconvenience.” Current ad suppression systems, which mute the sound, change the channel or turn the TV off during a commercial are “laborious and prone to error given that a user must guess as to when the commercial break will end,” said Sony. “Despite the ability to fast-forward through commercials, users must still deal with undershoot and overshoot problems.” Thus, despite the advantages of time-shifting over viewing in real-time, “commercial suppression in recorded content is still a manual and laborious task that is prone to error, thereby exacerbating the annoyance and inconvenience brought by commercials in the first place,” it said. Instead, the patented system relies on downloading and storing a library of templates of known commercials, the Sony document said. Downloading is automatic and ongoing, by Internet connection, and the templates contain both audio and video information on the ad’s content and duration, it said. The program being watched is continually compared with the stored templates, and when a match is found, the sound is automatically muted or playback fast-forwarded and the screen blanked until the template signals the end of the ad and switches the set back to normal viewing mode. Attempts to reach inventor Candelore were unsuccessful. Sony representatives didn’t immediately comment.
