Microsoft looks set to slug it out with Google for control of the living room TV following rumours that the tech giant is preparing to unleash a streaming dongle of its own, in direct competition with Chromecast.
No official pronouncements have yet been made about the secret device but a filing made to the Federal Communications Division suggests the mooted gadget, codenamed HD-10, will house an HDMI port, Wi-Fi and USB charging unit.
According to Nokia Power User this very same codename was described in the Wi-Fi Alliance product database as a Miracast dongle, fuelling the present bout of speculation.
As commentators have been swift to note Miracast is a wireless standard that lets devices connect to each other to share media, a vital tool for streaming content via the TV.
The technology does face some limitations however being unable to queue up multiple files from different sources or play multiplayer games. It is also incapable of playing media direct from online or cloud sources, relying instead on other devices to run the content and sending it to the telly.
