digital media hub - Computer Definition
A device that funnels multimedia content streamed from the Internet to a stereo or home theater system. 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, the popular 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). Also called a "set-top box" and an overabundance of other names (see digital media hubs), the device is located in the home theater cabinet and connects to an HDMI input on the A/V receiver or TV. This same streaming functionality is also built into modern Blu-ray players, A/V receivers and smart TVs.
