digital media hub - Computer Definition
A device that directs multimedia content streamed from the Internet to a stereo or home theater system. Also called a "set-top box" and an abundance of other names, it connects to an HDMI input on the A/V receiver or TV (see digital media hub names). Music-only hubs connect via audio jacks. This functionality is also built into Blu-ray players, A/V receivers and smart TVs. A digital media "server" is a hub that also stores content (see digital media server). Connected to the home network via Wi-Fi or Ethernet, digital media hubs may also stream photos, music and videos from the user's computer to the playback system. For example, Apple TV and Roku hubs provide access to Netflix, Hulu and other providers, and they can stream content from computers in the home network. To stream local content, Apple TV users must run iTunes in their PCs or Macs, and the Roku hubs require Plex (see Apple TV, iTunes, Roku and Plex).
