Apple announced the Apple TV 4K yesterday, an updated version of its living room set-top box that adds support for 4K and HDR video and boosts the processing power. There’s not much else new compared to the prior fourth-generation device: it offers the same apps, Siri remote, and a centralized TV hub that aggregates video from participating content providers.
