Roku-enabled TVs will be receiving a new OS update that will listen to what show or movie you're watching via your cable or satellite set-top or over-the-air antenna, in order to suggest internet-streaming content. "Compatible TVs will use automatic content recognition (ACR) technology to identify the content and then suggest additional viewing options available on via streaming services like Netflix, Hulu or Vudu," reports Variety. From the report: It may seem vaguely Big Brother-ish, but Roku is being careful about ensuring consumer privacy: Users will be required to enable the feature via an opt-in prompt. In addition, the "More Ways to Watch" feature can be turned off at any time (although Roku says viewing information collected prior to the feature being turned off will not be deleted). For now, the "More Ways to Watch" feature is available only in the U.S., and only for Roku-enabled television sets available from Best Buy's Insignia, Sharp, Hisense and TCL. It will be coming first to conventional HDTV models first, followed by support for 4K Roku TV models later this summer.
