What is Miracast?

Miracast, Wi-Fi Direct and DLNA explained

wifi allianceMiracast is a wireless, peer-to-peer screencasting technology that allows you to output video & audio both to and from a number of devices, although most usually from a mobile device to a compatible screen or receiver.

Miracast can be used to effectively mirror content stored on one device to another. For instance this could be a game you are playing or a movie you are watching (stored locally or streamed via the Internet). Business uses could include streaming a presentation or meeting content from a laptop to a projector.

The most common analogy to understand Miracast is to think of it as a ‘wireless HDMI cable’. Like HDMI, both ends must support Miracast or use an adapter. The content that can be shared is almost identical too; Miracast can securely transmit video up to 1080p with 5.1 channel sound.

Miracast uses Wi-Fi Direct

Wi-Fi Direct is an extension to the Wi-Fi protocol developed by the Wi-Fi Alliance and designed so that compatible devices can connect directly to each other, without the need for an intermediary router or hub. This is often referred to as an ‘ad-hoc’ network. Using Wi-Fi Direct to communicate ensures that traffic on a local network is kept to a minimum. This also makes Miracast a great choice for wireless communication in an environment where you don’t have access to the local network, such as corporate buildings or public Wi-Fi areas with strict rules on the content that can be transmitted.

You cannot use Miracast to stream content from an enabled device to a router / access point.

The following image explains the connections in a little more detail. The Miracast connection is between the source & display devices. A router / local network access point may be available, in some cases connected to one or both devices, and even delivering /receiving content to either, however its presence is irrelevant to the actual Miracast connection.

Netgear Push2TV Wireless Miracast Display Adapter PTV3000 Now Available

Netgear’s Miracast wireless display adapter now available from Clove Technology

netgear ptv3000 lifestyle

It may have been way back in February 2013 that we first detailed the Netgear Push2TV PTV3000, but it is only just now that we have confirmed availability in the UK. The reasons for the lengthy delay are not 100% clear, however can attributed in part to inconsistent performance and firmware in early models, as well as a slow adoption rate for Miracast technology in general.

netgear ptv3000 power

Happily all of this is a thing of the past and new stock of the PTV3000 is now available for £62.49 + delivery & VAT where applicable. Anyone who has been interested in the PTV3000 is recommended to get in quickly as we can’t be sure how long the current stock will remain available for!

Miracast is a wireless display technology that is finding its way on to more devices as of late, although is slipping under the radar of many users. Miracast enables compatible devices to ‘screen-share’ or stream content from one to the other, without the need for either to connect to separate network.

Miracast Explained

Unlike DLNA, which has been available for several years and requires both devices to be connected to a local network, Miracast creates an ad-hoc network between the two devices. This has the added benefit of reducing traffic on your local network, and also minimising the potential for signal interference and dropped packets with a dedicated connection between units.

netgear ptv3000 connectionMiracast is now a staple of Android phones since 4.2, although it has not been implemented by all manufacturers running this version. To check if your device has the capability, go to Settings > Display and look for a suitable option. In the Nexus 5 (4.4.2) this option is Cast Screen, although you may see it represented as Wireless Display or similar on other devices.

In order to display on another screen, the target either needs to be Miracast enabled, or have a suitable Miracast adapter connected to it. The Netgear PTV3000 is one such adapter, which connects to the display using HDMI. Once the PTV3000 is switched on, opening the appropriate setting on your device will search for nearby devices and form a connection once you confirm. From here, all content on your screen should be mirrored on the second display, allowing you to play games, browse the web or output video.

Netgear PTV3000 Push2TV miracast wireless display adapter

Miracast is the latest technology to embrace the mobile market that allows you to share the content from your Miracast enabled smartphone or tablet to a HD display without wires.

Few televisions have this technology built in and it is probably fair to say you do not change your HD display as regularly as your phone (or maybe you do). Well if you would like to essentially give your TV the wireless display option using the Miracast technology, the Netgar PTV300 adapter will allow you to do just this.

Connect the little box to the HD display with an HDMI cable, plug in the power and you are set to go.

UK pricing is still to be confirmed, but stock is expected in April.

New HTC smartphone to have Miracast

It is fair to say that we can often assume what features a new phone will have, but it is always good to have some evidence rather than just rumour before a device is announced.

As we browsed the WiFi Alliance’s website (www.wi-fi.org) as we added the Netgear PTV3000 to our website we came across this:

image

The above is certification from the WiFi Alliance for Miracast technology for a HTC smartphone known under various SKU codes: PN07XXXXX/PN0713000/PN0720000/

Now we have no conclusive evidence that this is for the phone that HTC are set to announce on the 19th February, but bearing in mind the certification was granted on the 21st of this month, it is more than likely the case.

You can see the certification yourself on the link below: http://certifications.wi-fi.org/pdf_certificate.php?cid=WFA16349

We will of course find out for sure on the 19th whether the new product will have Miracast, but if it does and you would like to use this feature, you may benefit from the PTV300, details of which can be found here.

WiFi Miracast – what does it do?

We explain how WiFi Miracast allows you to stream your device display to a compatible screenimage

The most recent update to Android Jelly Bean (4.2) contains support for a new and currently still little known streaming technology called Miracast, but just what is it and how does it work? Essentially Miracast is an update to the WiFi standard that allows you to stream the display of your device, in real time, to a compatible screen.

Similar technologies exist using DLNA, however the downside to these is that companies implementing them generally utilise proprietary software / hardware in addition to your device if it is not made by that company. An example is Samsung with AllShare. For instance I have AllShare on my Samsung Galaxy S3 but unless I have a Samsung TV also with AllShare, I need to buy the AllShare adaptor to get it working and have the AllShare software on my laptop to share from there as well.

Miracast allows devices from all manufacturers to work together without specific applications and accessories. Also, even though it is part of the WiFi standard, Miracast does not require a normal WiFi network and WiFi router to operate. Certified devices use WiFi direct to make an ad-hoc network and talk directly to each other. Compatible Miracast devices are scarce right now although the new Nexus devices (Nexus 4 and Nexus 10) from Google are included and there are a list of devices becoming available in the near future (such as Samsung’s upcoming Echo-P TV range) available by searching at the WiFi Alliance website.

Eventually WiFi direct and Miracast and will be supported internally on pretty much all new smartphones, tablets, laptops, TVs and other devices with a display. LG, Sony and others are also developing dongles to plug into older (read current) TVs that do not have support. So if you are a heavy multimedia consumer and the idea of sharing content easily is appealing, look out for the WiFi direct and Miracast certified badges on upcoming technology!

Xperia T 4.0.4 update rolling out, adds Miracast compatibility

imageSony has just announced that the Android Ice Cream Sandwich 4.0.4 update is now rolling out for the Xperia T and Xperia TX in European and Asian markets. 

The most noticeable part of the update is Miracast compatibility. This was recently announced as part of the specification of the new Nexus range and enables the sharing of your device’s screen with other Miracast devices, such as Miracast enabled TVs. However, as SlashGear has recently pointed out, there are at the moment only a handful on Miracast compliant devices at the moment.

Another impressive part of the Xperia T update is improvement of battery standby time by up to four times. When the device has been asleep for a few minutes, Wi-Fi and data traffic will be automatically turned off and most apps will become inactive. This will not however affect the handsets ability to receive calls and text messages when in standby mode.

There’s also an update to Sony’s media apps included with the 4.0.4 update.
