NEW YORK — More choice — and confusion — is coming to the next generation of TVs.
At least three new software systems were announced Monday for Internet-connected television sets, which let viewers watch Internet video and interact with friends online on the big screen. The new smart TV operating systems will compete with software already available from Google and individual TV manufacturers.
But more consumer choice will also mean more difficulties for services such as Hulu and Netflix to write apps. As a result, app selection on any given TV will be limited.
To fully enjoy the range of Internet video on the TV, many consumers will still have to buy a separate device such as Apple TV and Roku — and then figure out how to install it. Those devices cost about $100, though Google sells a $35 Chromecast device with fewer features.
TV manufacturers have been pushing smart TVs to give consumers a reason to upgrade their sets more frequently. The Internet capability also keeps the TV central to households, even as people spend more time watching Internet video.
But so far, apps on smart TVs aren't as extensive as what's found on phones and stand-alone streaming devices, in part because no one operating system has enough users to make it a priority for app makers.
"I keep hoping we will see convergence," said Colin Dixon, chief analyst at nScreen Media, a research firm in Sunnyvale, Calif. "Unfortunately, we keep seeing the number of operating systems increasing, not decreasing."
