Plugging your laptop into a television or projector is something many of us do on a daily basis. But cords can be as limiting as they are ugly. There are an increasing number of solutions to this, but one that is already built in to many laptops is Intel's Wireless Display (WiDi) solution. WiDi allows you to send high definition video and audio to a display wirelessly allowing for completely cable-free presentations and a greater flexibility in computer and display placement.

With Smart TVs becoming nearly ubiquitous now more and more of these displays also bundle in support for wireless display technologies, including WiDi. For those displays that don't have it built in there are external adapters available for purchase such as the Netgear PTV3000. Plug the external adapter into power and HDMI behind your display and you're free to move your WiDi laptop to wherever you need it.

We used an HP EliteBook 840 and an LG 50LB6100 Smart TV for this example. Virtually any new computer that includes an Intel processor, Intel HD graphics, and Intel wireless card supports WiDi. A wide variety of Smart TVs also include support for WiDi such as LG, Samsung, and Toshiba. As for projectors, both Epson and NEC have product lines that come with WiDi support. Intel has a short list of devices and product lines that support WiDi here. Although more and more displays support Intel’s Wireless Display, most have the feature disabled by default. Every TV is different, but on our LG model you would open Settings > Network > Miracast/Intel’s WiDi and change it to “On”.

Intel Android device USB driver on 32-bit and 64-bit PCs. This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system on a laptop or desktop PC from drivers without restrictions. Intel Android device USB driver 1.10.0 is available to all software users as a free download for Windows 10 PCs but also without a hitch.

Once this feature is turned on within your display settings, there are only a few steps required to get WiDi up and running:

  1. Download and run the Intel WiDi Update Tool. It will tell you whether your computer supports Intel WiDi and update any software or drivers needed to get it working.

    If your computer’s hardware is not compatible with WiDi, the Update Tool will abort (shown below) and you won’t be able to take advantage of Intel’s Wireless Display technology.

  2. After successfully running the WiDi Update Tool, you will be able to detect nearby wireless displays within range. If you're using Windows 7, open the Intel WiDi utility and scan for wireless displays as shown:

    If you're using Windows 8.x, open the Charms menu then select Devices > Project > Add a wireless display:

  3. The first time you connect your computer to a wireless display, you will be prompted to enter a randomly generated 8 digit PIN shown on the external display.
  4. Once connected, you can disconnect and reconnect using the Intel WiDi/Charms menu. You can manage your wireless display just like any other monitor, cloning or extending the desktop to best suit your needs.
    1. To manage your displays, right click a blank space on your Desktop and click Screen Resolution. From there you can click the “Multiple Displays” drop down and choose your preferred duplicate (clone) or extend options.

If both your computer and your display have WiDi built in, setup truly can be this simple. But nothing is perfect and sometimes other steps also need to be taken. Here are some of the more common problems you can encounter:

  1. Software firewalls and behavior monitors can pose a problem with some wireless display adapters. The exact steps vary depending on the software firewall you’re using, but if you’re using the built-in Windows firewall, follow these steps:
    1. Open the Windows Firewall by going to Control Panel > System and Security > Windows Firewall, or typing “Windows Firewall” into Start Search.
    2. Click “Allow a program or feature through Windows Firewall”
    3. If you scroll down, you may find a “Wireless Display” option already present. If so, make sure it is enabled and applied to your network type. If, like above, it is enabled and you cannot connect, click the “Allow another app”
    4. Click “Browse” and navigate to 'C:Program FilesIntelWiFibinPanDhcpDns.exe', then click Add. It will then display in the list above.
      • On Windows 7 computers, you will need to repeat steps iii) and iv) to also add 'C:WindowsSystem32WUDFHost.exe'
    5. After you have added that entry, click OK and close Windows Firewall
  2. WiDi is incompatible with the Dynamic Frequency Selection (DFS) feature used on some 5 GHz wireless networks. Technically WiDi does not require your laptop to be connected to a wireless access point in order for it to connect to a wireless display, but if you do need to be connected to a wireless network using DFS at the same time, this can pose a problem.There are two options to bypass this: Disable DFS on your wireless access points (usually the less preferable option), or set your Intel wireless adapter to prefer 2.4 GHz networks. The latter option will only be available if there are 2.4 and 5 GHz networks broadcast under the same SSID. Otherwise you would need only connect to your computer a 2.4 GHz network.To set a preferred frequency band:
    1. Open Network and Sharing Centre from the Control Panel and click Change adapter settings, or simply enter “ncpa.cpl” into Start Search in order to open the Network Connections window directly
    2. Right click your Wireless Network Connection and select Properties
    3. Click the Configure button
    4. Click Advanced > Preferred Band then click the dropdown menu and select “Prefer 2.4 GHz band”
    5. Click OK and close the Network Connections window. Your wireless card will now connect to the 2.4 GHz portion of your network automatically.

Setting up a wireless display takes relatively little effort but can offer a great deal of convenience. Ensuring that you procure WiDi compatible computers and displays will help make display connectivity that much easier and virtually seamless.

Introduction

Wireless display technology is becoming more and more popular on Android* phones and tablets since Google started supporting Miracast on Android 4.2. Wireless display technology makes it easier for end users to expand their phone’s LCD size. I think there is a good chance that ISVs will integrate the wireless display feature into their applications, especially games and video players.

But how to realize Intel® Wireless Display differentiation for Miracast on Android for x86 phones is a big challenge for enabling ISVs. This article introduces how to enable dual display differentiation for Miracast by showing a case study of enabling iQiyi online video player and WPS office on K900. We hope that lots of amazing applications can be enabled in the future.

What is Miracast

The Wi-Fi Alliance officially announced Wi-Fi* CERTIFIED Miracast on 2012.9.19 , which is a groundbreaking solution for seamlessly displaying video between devices, without cables or a network connection. Users can do things like view pictures or videos from a smartphone on a big screen television, share a laptop screen with the conference room projector in real time, and watch live programs from a home cable box on a tablet. Miracast connections are formed using Wi-Fi CERTIFIED Wi-Fi Direct*, so access to a Wi-Fi network is not needed—the ability to connect is inside Miracast certified devices.

The connection of Miracast is based on a Wi-Fi direct, peer to peer connection. The Wi-Fi-based Miracast architecture is shown below.


Figure 1: Miracast* architecture

There are four modes of Miracast connection as shown below:


Figure 2: Miracast* connection modes

With a Miracast connection, you can enable connectivity across devices without Wi-Fi AP infrastructure, as topology 1 shows. You can also connect to a display via an adaptor while connecting to an AP, as topology 2 shows. It is very convenient to watch online video at home with this mode. If you have a smart TV that also supports Miracast, your TV, AP, and your smartphone can even connect to each other, as topology 4 shows.

According to the Miracast standard, the interactive mode of source and display devices can be diagrammed as follows:


Figure 3: Miracast* session management

Source and display devices discover each other’s Miracast capabilities prior to connection setup. The connection is based on Wi-Fi direct or TDLS. Source and display devices determine the parameters for the Miracast session based on capability negotiation. The negotiation process is based on the TCP connection. Source devices will transfer content to display devices via MPEG2-TS format based on the UDP connection.

Miracast wireless streaming-supported formats are listed in Table 4.

Miracast on Android 4.2

Google started supporting Miracast on Android version 4.2. End users can share movies, photos, YouTube videos, and anything that’s on your screen with HDTV via wireless display technology. The external HDTV is listed as an external display.

Now Miracast on Android supports clone mode and presentation mode, as shown below:


Figure 5: Miracast* support modes

Clone mode duplicates the phone display on the remote display. The resolution of the frames sent to the adapter matches the resolution of the local display. In this mode, both local and remote displays are turned on and show the same content.

In presentation mode, Android now allows your app to display unique content on additional screens that are connected to the user’s device over either a wired connection or Wi-Fi. The apps must be modified to support this mode, or they will default to clone mode.

Develop differentiation for Miracast on Intel Architecture (IA) phone

Intel’s wireless display solution on Android phones and tablets is fully compatible with Miracast. We also enable some apps with differentiation usages to Miracast on IA phone.

The first one is to enable iQiyi to realize the video background streaming function. Users can send video to a remote display at 1080p resolution using a iQiyi app that enables background streaming while users can navigate out of the app and play 1080p video on the local screen or use any other application, including sending email or accessing their browser without any disruption to background playback, as shown below:


Figure 6: iQiyi video BGM function

The second one is to enable WPS office to realize split the UI function on both local and remote displays. When connecting to TV via wireless display, the enabled WPS office app can show PPT slides on the remote screen while showing PPT notes on the phone’s screen, which is very convenient for the speaker. We plan to add a timer clock on the phone’s screen to give a time reminder to the speaker in the future.

These two differentiation usages are developed based on Miracast’s Presentation mode using the phone’s IA hardware capability.

Case study: How to enable dual display differentiation usages

In this section, I will introduce how to realize a video background streaming function based on our experience of enabling a iQiyi app.

As we know, to realize the video BGM function, the key difficulty is to get a service to play video in the background and deal with the surface view or video view correctly. When users press the home key, the surface view or video view will be destroyed automatically, so we have to apply a secondary display to show the background streaming video. The program flowchart is shown below:

Figure 8: Background video streaming flow chart

To create unique content for a secondary display, extend the Presentation class and implement the onCreate() callback. Within onCreate(), specify your UI for the secondary display by calling setContentView(). As an extension of the Dialog class, the Presentation class provides the region in which your app can display a unique UI on the secondary display.

There are two methods for applying the secondary display for your presentation. Use either the DisplayManager or MediaRouter APIs. The easiest way to choose a presentation display is to use the MediaRouter API. The media router service keeps track of which audio and video routes are available on the system. The media router recommends the preferred presentation display that the application should use if it wants to show content on the secondary display.

Here's how to use the media router to create and show a presentation on the preferred presentation display using getPresentationDisplay().

Another way to choose a presentation display is to use the DisplayManager API directly. The display manager service provides functions to enumerate and describe all displays that are attached to the system including displays that may be used for presentations.

The display manager keeps track of all displays in the system. Here's how to identify suitable displays for showing presentations using getDisplays(String) and the DISPLAY_CATEGORY_PRESENTATION category.

Developers can Reference the presentation demo code in Android SDK shown as below:

Summary

Besides the selling point of Intel Inside® for IA-based phones and tablets, the wireless display feature may become a shining point. ISVs should take notice and develop more innovative usages based on wireless display, especially the dual display differentiation usages.
