Set-Top Box for T-Mobile’s Upcoming TV Service Surfaces Online

T-Mobile’s upcoming TV service may be just around the corner, if a new FCC filing is any indication: A set-top box likely built for the service surfaced in a filing made by Kaonmedia, a company that previously build set-top boxes for T-Mobile’s Layer3 TV subsidiary.The box is branded with T-Mobile’s T logo, and is being called the “T-Mobile Mini” in a manual included with the filing. The FCC label of the device still is Layer3 TV-branded.A T-Mobile spokesperson sent Variety the following comment after this story was first published: “We’re hard at work on our new home TV solution, and after launch, we’ll continue to innovate and expand T-Mobile’s entertainment solutions over time.”There’s little to gather from the manual about the exact functionality of the device, but photos show that it features HDMI pass-through, which may be used to incorporate third-party streaming devices or game consoles without the need to switch back and forth between different TV inputs.The device also seems to offer an Ethernet port as well as a USB port for manual software updates. There is no notable Coax input, suggesting that the device is meant to receive TV programming over the internet as opposed to traditional cable infrastructure –a departure from Layer3 TV’s more cable-centric approach.
