Media rendering box supports WiDi and Miracast

Nov 8, 2013 — by Rick Lehrbaum 5,599 views

ViewSonic announced an embedded Linux-powered wireless receiver for rendering multimedia content on projectors, desktop monitors, large format displays, and HDTVs. The ViewSync WPG-370 Wireless Presentation Gateway streams HD content from Windows, iOS, and Android mobile devices via Miracast, Intel WiDi (Wireless Display), and other protocols, and can also play content from directly plugged-in USB flash.

“Now that tablets deliver enough processing power to support most business applications, users are often choosing to present from their tablets,” stated Jeffrey Hsieh, ViewSonic’s senior manager of product marketing. “Additionally, as individuals experience wireless streaming capabilities with devices like Google’s Chromecast and Apple TV in their everyday personal lives, we anticipate that they will look for a natural extension of this benefit in their professional work environment as well.” To tap into this trend, ViewSonic came up with the ViewSync WPG-370 wireless gateway, a device geared toward enterprise, SMB, educational applications, adds the company.

In order to stream content to the WPG-370 via Intel WiDi, PCs and laptops need to be equipped with Intel WiDi technology, which requires the presence of Intel Core i3/i5/i7 processors, among other factors. According to ViewSonic, WiDi support is now standard on laptops using Intel Core i5 or later processors, and is optionally available on Core i3-based machines.


ViewSonic’s media gateway device appears to be similar in capabilities to Actiontek’s ScreenBeam device (pictured at the right). Actiontec currently lists a number of Android devices as being capable of streaming via WiFi Miracast to their device, including Google’s Nexus 4, the HTC One, LG’s Optimus G, Samsung’s Galaxy S3, Galaxy Note 2, and Galaxy Note 10.1, and Sony’s Xperia T and Xperia V, when running Android 4.x or higher.

Users of Android and iOS handhelds can install the free, third-party iMediaShare app on their devices, which will enable them to stream video, audio, and image files wirelessly via DLNA to the WPG-370, says ViewSonic.

The WPG-370 also lets users play video and audio files, and display photos, directly from a plugged-in USB flash drive. The WPG-370’s remote control (shown below; click image to enlarge) enables convenient control of the device while rendering media from a USB source.

    It is based on Linux. It is powered by Linux. It does not support Linux. Groovy. Yawn.
