What’s WiDi?

Intel WiDi LogoWiDi (Wireless Display) is a wireless display technology developed by Intel. It enables users to wirelessly stream music, movies, photos, videos and apps from a WiDi enabled computer to another compatible HDTV or through the use of a WiDi adapter with other non compatible HDTVs. Intel WiDi supports HD 1080p video quality, 5.1 surround sound, and low latency for interacting with applications that are sent to the TV from a PC.

Miracast standard was supported in Intel WiDi version 3.5. Visonicom RealCast PTV WiFi display adapters support WiDi 3.5 or greater.

What’s Miracast?

wifi-certified-miracastMiracast, created by the Wi-Fi Alliance, is a p2p wireless screen casting standard via Wi-Fi Direct connections. It enables wireless delivery of audio and video (up to 1080p HD video and 5.1 surround sound (AAC and AC3 are optional codecs) to or from desktops, tablets, mobile phones, and other devices. It allows users to echo display from a phone or tablet PC onto a TV, share a laptop screen with the conference room projector in real-time. Both the sending and receiving devices must support Miracast technology. However, to stream music and movies to a device, such as a TV or projector without Miracast support, a Miracast support WiFi display adapters in needed to plug into HDMI port, thus Miracast can be regarded as a Wireless HDMI cable.

Miracast support is built into Android 4.2 or later, BlackBerry 10.2, and Microsoft Windows 8.1. Another way to support Miracast in Windows is with Intel's proprietary WiDi v3.5 or above. Apple’s equivalent WiFi display technology is its own AirPlay mirroring on OS X, while for Linux desktop there was MiracleCast which provides early support for miracast but is not tied to that single protocol.

For Miracast enabled Android/Windows users, Visonicom Realcast PTV adapters may help to mirror you personal device screen to HDTV or projector; for most compatibility users can try our universal WiFi display gadget - EZCast WiFi display dongles.

What is AirPlay?

Airplay logoUnlike Miracast and DLNA, AirPlay is proprietary and not an open standard, which means Apple gets to control who uses it.

AirPlay is to share everything including music and movies to apps and games from your iPhone, iPod touch, and iPad to your Apple TV

AirPlay is Apple's term for their audio and video streaming technology. It's what lets your iOS 5 device, or iTunes on Mac or Windows, beam videos over Wi-Fi to your Apple TV so you can watch movies and play games on your big screen TV, or music to your AirPort Express router, so you can listen on your higher quality speakers.

AirPlay Mirroring is a recent addition to iOS that works with iPad 2 or iPhone 4S and above to let you not only beam music or video, but entire iPhone or iPad apps. Anything from Facebook to your favorite crosswords, racing, or fighting game can be sent via Apple TV to your HDTV, with your iPhone, iPod touch, or iPad remaining active as the controller.

Visonicom RealCast PTV WiFi display adapters support Apple AirPlay very well, and so do the universal WiFi display gadgets - EZCast WiFi display dongles, which can work as AirPlay adapters.
