HDHomeRun

HDHomeRun is a network-attached digital television tuner box, produced by the company SiliconDust USA, Inc.
Overview
Unlike standard set-top box (or set-top unit) appliances, the HDHomeRun does not have a video output that connects directly to the user's television. It instead receives a live TV signal and then streams the decoded video over a local area network to an existing smartphone, tablet computer, smart TV, streaming device, computer, or game console. This allows it to stream content to multiple viewing locations.
Compatibility
The HDHomeRun can be controlled and viewed from a wide variety of DVR/PVR software, including Windows Media Center for Windows XP through 8.1, EyeTV 3 for macOS, and Myth TV for Linux.
Newer models of the HDHomeRun are DLNA certified.

HDHomeRun PRIME
Introduced in late 2011, the HDHomeRun PRIME provided the ability to view and record all digital cable channels the user subscribed to without using a cable-supplied set-top box. The device employed a CableCARD to replace the set-top box. The HDHomeRun PRIME could be integrated with Windows Media Center. With 3 tuners, the PRIME let you record two programs and watch another program live simultaneously. Due to a change in FCC regulation (cable service providers no longer have to make CableCARDs available to their customers), they are no longer in production.
HDHomeRun Premium TV
Launched in 2018, HDHomeRun Premium TV was a virtual MVPD service that worked with the HDHomeRun PRIME and HDHomeRun DVR service. A notable feature of this service was the ability to record the channel streams to a local hard drive for time-shifted viewing. In March 2019, HDHomeRun announced that it would shut down its Premium service.
