  • Our presentation will include providing an overview of Miracast and Intel Wireless display technologies, a quick look at available phone and tablets and display devices in the market today supporting second screen usage, some second-screen use cases and idea, followed by demo of an in-house developed 2-screen media player application. Then in the final part of the presentation we will explain how to develop with the Android secondary-screen APIs complemented with a live coding.
  • - Allows content streaming from one Miracast certified device to another- Wireless replacement of a wireless HDMI or HML cable between a Source device (i.e. smartphone or tablets) to a sink or Display device (i.e. TV, projector, etc..).- Built upon exiting standards such as H.264 (MPEG-4 AVC) for video compression, and WiFi Direct …- Based on Intel’s Wireless Display (aka WiDi) specification.- Supports HD (1080p) at 30FPS (or 720p at 60FPS for smoother playback)
  • So, what is Intel WiDi:-It Miracast certified, so any Miracast certified adapter should work. With Intel Wdi it is preferred to use a Intel Certified adapter - we will lokk at these later…Supports 1080p At 30FPS or 720p/60 fps for smoother motion video Display protected content wirelessly with HDCP (High bandwidth Digital content protection) 2.1Can be used with Android 4.2 Presentation API for dual screen usage, also support 2 addition modes- And available on most current ATOM SOCs.
  • Miracast Concept at a high-level [1] Before any content can be sent a link or session must be established in prep for content streaming (this is done by the phone/tablet scanning for the available displays (& capabilities)**, and asks the user to select one) typically via through the display settings[2] When the connection is, the source performs composition of the Audio and Video and encodes the content it into a mpeg2 bit-stream and the transmits it over WiFi Direct to the Display device. Once the Display device receives the content it decodes the renders it to the Display.Session Management takes care of: connection setup, capability negotiation, DRM Support (mandatory for Intel WiDi), Session establishment and streaming, **payload control/handshaking** and finally display session teardown.Supported formats for video: H.264 (aka Advanced Video Coding) and Audio: Linear PCM (LPCM) 16 bits, 48KHz) 2 channels. Optional audio codes are based on LPCM 16 bits, 44/1KHz sampling, 2 channels, Advanced Audio Coding (AAC) and Dolby Advanced Codec 3 (AC3)The next slide will go a little deep in to the Miracast architecture …
  • For full list of Wi-Fi Miracast certified devices (that even includes TV built in refrigerators) go to www.wi-fi.orgFor full list of Miracast™ enabled source and display devices checkout the WiFi Alliance web site: http://www.wi-fi.org/wi-fi-certified-miracast%E2%84%A2http://certifications.wi-fi.org/search_products.php?search=1&advanced=1&selected_certifications%5B%5D=69
  • Low latency gaming- 50ms to 60ms (depends on conditions) vs. competition is 100 Easy pairing: - Instead of typing a 10 digit code, you can use QR codesfull 1080p- always supports content up to 1080p, other Miracast devices might not be able to support especially with the low latency.link health indicator- helps you know your signal strength so you know if you are too far away or if interferencebest channel selection- Picks the fastest of the ABGN (supports both 2.4G and 5G Hz)Other differentiation1) Extended Video mode2) Multi-Tasking -Only with selected OEMS - we add support for multiple video stream playbacks simultaneously, remotely playing video while locally doing anything e.g. play a game, play a video, phone call etc.
  • Info from www.gsmarena.comAny more Intel phones??This slide shows some of the devices that run or upgradable to Android 4.2.2 that are either Miracast™ compliant or support HDMI either via MHL or micro-HDMI that are currently on the Market or will be very soon. For full list of devices you can search on gsmarena.com. I lot of my testing has been with the Lenovo K900 and Asus memo pad with netgear PTV3000 and Actiontech sunbeam – and I can say it works very well.
  • In Android 4.2, there is no a wireless display app in the IA phone’s menu.The connection item is under SettingDisplayWireless Display.You should also search first, the click to connect without inputting 8 digital number
  • 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. The frames sent to the adapter are captured from the graphics engine, that is from LCD’ frame buffer. You can see in the right photo, In Clone mode,the phone and the TV show the same picture.
  • Extended Video Mode is activated when the user plays video through Android’s Media Player application.In this mode, the original resolution of the video content is sent to the adapter. While in this mode, the local display remains turned off and the video content appears only on the remote display alone. The user is allowed to touch the local display to bring up the slider controls and control the playback. The frames being sent to the adapter are captured from the fullscreen video decoder.Shown as the right photo, Video is playing on TV while there is only title bar on the phone’s screen. Now widi can support 1080p HD video at 30fps.TODO: check…
  • In fps: can use orientation of the device to start shooting.Screenshot taken from Open-Source (GPL) game Nexuiz.
  • The Android Second-screen API (Presentation)was introduced in Android 4.2, the Presentation API allows you to …
  • is associated with the target Display at creation time and configures its context and resource configuration according to the display's metrics.
  • Add getSystemService line ?Display Manager: class that holds all displays connected. Requires either developer or end user to choose a Display.Media Router: The MediaRouter class holds all possible routes for audio and video to go (e.g. speakers and displays) but differs from Display Manager as it will automatically select the best Route (or Display in our case)
  • Your route can change, your presentation display can be disconnected, your activity can be paused, etc. Once you created your presentation, you need to care about all this.A presentation is automatically canceled when its display is removed. But the activity must take care of pausing its content when the activity itself is paused, and test if the display still exists (so the presentation) while resuming, to resume or restart it.
  • If you don’t have a WiDi adapter, Android 4.2 includes an Developer options that allows you to simulate the second display, you can choose res and dpi and it will then create an overlay of that display.If developer options don’t show up, tap on Build number within About phone around 5 times to bring it up.
  • + setRouteTypes(MediaRouter.ROUTE_TYPE_LIVE_VIDEO) on it.Using setRouteTypes with ROUTE_TYPE_LIVE_VIDEO flag (API level 17) will allow mirrored version of the built in screen or a customized version (using presentation class) to be send to second screen.ActionBarActivity Base class for activities that use the support library action bar features.  MediaRouteActionProvider The media route action provider displays a media route button in the application's ActionBar to allow the user to select routes and to control the currently selected route.  MediaRouteButton The media route button allows the user to select routes and to control the currently selected

    • 24. Android* Presentation API Класс Presentation в Android* 4.2 (API Level 17), позволяет: • Использовать второй экран не заботясь о способе подключения • Использовать MHL*, HDMI*, SlimPort* & Miracast* совместимые устройства • Контролировать контент, отображаемый на внешнем экране Software and Services Group
    • 25. Объект Presentation • Представление должно наследовать Presentation public class DemoPresentation extends Presentation { • В момент создания ассоциируется с объектом Display • Presentation наследуется от Dialog, так же как для Dialog жизненный цикл зависит от Activity Dialog Presentation Activity должно контролировать представление (Presentation) в моменты изменения текущего статуса (onPause, onStop, onResume)
    • 26. Использование Presentation API Сначала необходимо получить объект Display, на котором будет отображаться представление: 1. MediaRouter API (в API 16): автоматический выбор наиболее подходящего // Get the media router service. MediaRouter mMediaRouter = (MediaRouter)getSystemService(Context.MEDIA_ROUTER_SERVICE); // Use the MediaRouter that supports live video MediaRouter.RouteInfo mRouteInfo = mMediaRouter.getSelectedRoute(MediaRouter.ROUTE_TYPE_LIVE_VIDEO); Display presentationDisplay = mRouteInfo.getPresentationDisplay(); 2. Display Manager API (в API 17): Перечисление доступных // Get the display manger service. DisplayManager mDisplayManager = (DisplayManger)getSystemService(Context.DISPLAY_SERVICE); // enumerate the displays Display[] displays = mDisplayManager.getDisplays(DisplayManger.DISPLAY_CATEGORY_PRESENTATION);
    • 27. Presentation API How to get a Presentation displayed: MediaRouter. getSelectedRoute (ROUTE_TYPE_LIVE_VIDEO) MediaRouter. routeInfo new Presentation (activityContext, display) .show() getPresentationDisplay() Используя MediaRouter.addCallback, необходимо отслеживать и обрабатывать: • onRouteUnselected • onRouteSelected • onRoutePresentationDisplayChanged Внутри Activity, создавшей представление: • onResume • onPause
    • 28. Тестирование приложений Варианты: • На устройствах с наличием возможности подключения (Miracast, HDMI, и т.д.) • В режиме эмуляции – новая возможность в Android* 4.2 (Инструменты разработчика). Позволяет выбрать разрешение и DPI, после активации отображается поверх экрана. Software and Services Group
    • 29. Добавление MediaRouteButton res/menu/default.xml: <item android:title="Media Route Settings" android:actionProviderClass="android.app.MediaRouteActionProvider" android:showAsAction="always" /> //Sets Media Route Button to second screen mode mediaRouteActionProvider.setRouteTypes (MediaRouter.ROUTE_TYPE_LIVE_VIDEO); //Launches the Wireless display setting intent startActivity(new Intent ("android.settings.WIFI_DISPLAY_SETTINGS"));
    • 30. Реализация интерфейса Presentation Используется тот же стиль, что и для Dialog. Разрешение и DPI: TV setting Разрешение Density Screen Density Display Resolution Screen size identifier 720p 1280 x 720 px tvdpi 213 dp 960 x 540 dp large 1080p 1920 x 1080 px xhdpi 320 dp 960 x 540 dp large source: https://developers.google.com/tv/android/docs/gtv_android_patterns Density телевизора и смартфона сопоставимы, больший размер экрана компенсируется расстоянием. Тема по умолчанию Holo Dark: светлый текст на темном фоне легче читается на телевизоре. Всегда ландшафтный режим ориентации
    • 31. Wireless Display APIs в Android* 4.2 • Диалог настроек беспроводного дисплея можно вызвать используя android.settings.WIFI_DISPLAY_SETTINGS, так же возможны варианты – Samsung*: com.samsung.wfd.LAUNCH_WFD_PICKER_DLG – HTC*: com.htc.wifidisplay.CONFIGURE_MODE_NORMAL Software and Services Group

    • 38. Risk Factors The above statements and any others in this document that refer to plans and expectations for the third quarter, the year and the future are forward-looking statements that involve a number of risks and uncertainties. Words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “may,” “will,” “should” and their variations identify forward-looking statements. Statements that refer to or are based on projections, uncertain events or assumptions also identify forward-looking statements. Many factors could affect Intel’s actual results, and variances from Intel’s current expectations regarding such factors could cause actual results to differ materially from those expressed in these forward-looking statements. Intel presently considers the following to be the important factors that could cause actual results to differ materially from the company’s expectations. Demand could be different from Intel's expectations due to factors including changes in business and economic conditions; customer acceptance of Intel’s and competitors’ products; supply constraints and other disruptions affecting customers; changes in customer order patterns including order cancellations; and changes in the level of inventory at customers. Uncertainty in global economic and financial conditions poses a risk that consumers and businesses may defer purchases in response to negative financial events, which could negatively affect product demand and other related matters. Intel operates in intensely competitive industries that are characterized by a high percentage of costs that are fixed or difficult to reduce in the short term and product demand that is highly variable and difficult to forecast. Revenue and the gross margin percentage are affected by the timing of Intel product introductions and the demand for and market acceptance of Intel's products; actions taken by Intel's competitors, including product offerings and introductions, marketing programs and pricing pressures and Intel’s response to such actions; and Intel’s ability to respond quickly to technological developments and to incorporate new features into its products. The gross margin percentage could vary significantly from expectations based on capacity utilization; variations in inventory valuation, including variations related to the timing of qualifying products for sale; changes in revenue levels; segment product mix; the timing and execution of the manufacturing ramp and associated costs; start-up costs; excess or obsolete inventory; changes in unit costs; defects or disruptions in the supply of materials or resources; product manufacturing quality/yields; and impairments of long-lived assets, including manufacturing, assembly/test and intangible assets. Intel's results could be affected by adverse economic, social, political and physical/infrastructure conditions in countries where Intel, its customers or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in currency exchange rates. Expenses, particularly certain marketing and compensation expenses, as well as restructuring and asset impairment charges, vary depending on the level of demand for Intel's products and the level of revenue and profits. Intel’s results could be affected by the timing of closing of acquisitions and divestitures. Intel's results could be affected by adverse effects associated with product defects and errata (deviations from published specifications), and by litigation or regulatory matters involving intellectual property, stockholder, consumer, antitrust, disclosure and other issues, such as the litigation and regulatory matters described in Intel's SEC reports. An unfavorable ruling could include monetary damages or an injunction prohibiting Intel from manufacturing or selling one or more products, precluding particular business practices, impacting Intel’s ability to design its products, or requiring other remedies such as compulsory licensing of intellectual property. A detailed discussion of these and other factors that could affect Intel’s results is included in Intel’s SEC filings, including the company’s most recent reports on Form 10Q, Form 10-K and earnings release.
