This article is about video encoding and decoding software. For container file format, see . Windows Media Video (WMV) is the name of a series of video codecs and their corresponding video coding formats developed by Microsoft. It is part of the Windows Media framework. WMV consists of three distinct codecs: The original video compression technology known as WMV, was originally designed for Internet streaming applications, as a competitor to Real.

After standardization by the Society of Motion Picture and Television Engineers (SMPTE),[1][2] WMV version 9 was adopted for physical- delivery formats such as HD DVD and Blu- ray Disc and became known as VC- 1.[3][4] Microsoft also developed a digital container format called Advanced Systems Format to store video encoded by Windows Media Video. History[edit]In 2. Microsoft drafted a video compression specification based on its WMV 9 format and submitted it to SMPTE for standardization. The standard was officially approved in March 2. SMPTE 4. 21. M, better known as VC- 1, thus making the WMV 9 format an open standard. VC- 1 became one of the three video formats for the Blu- ray video disc, along with H. MPEG- 2 Part 2 and H. MPEG- 4 AVC.[3][4]Container format[edit]A WMV file uses the Advanced Systems Format (ASF) container format to encapsulate the encoded multimedia content. While the ASF can encapsulate multimedia in other encodings than those the WMV file standard specifies, those ASF files should use the . ASFfile extension and not the . WMV file extension.[5]The ASF container can optionally support digital rights management using a combination of elliptic curve cryptography key exchange, DES block cipher, a custom block cipher, RC4 stream cipher and the SHA- 1 hashing function. Although WMV is generally packed into the ASF container format, it can also be put into the Matroska[6] or AVI container format. The resulting files have the . MKV and . AVI file extensions, respectively. One common way to store WMV in an AVI file is to use the WMV 9 Video Compression Manager (VCM) codec implementation.[7][8]Video compression formats[edit]Windows Media Video[edit]. Diagram illustrating the relative frame sizes of several common video resolutions targeted by Windows Media Video 9 Professional, starting with 4. Windows Media Video (WMV) is the most recognized video compression format within the WMV family. Usage of the term WMV often refers to the Microsoft Windows Media Video format only. Its main competitors are MPEG- 4 AVC, AVS, Real. Video, and MPEG- 4 ASP. The first version of the format, WMV 7, was introduced in 1. Microsoft's implementation of MPEG- 4 Part 2.[9] Continued proprietary development led to newer versions of the format, but the bit stream syntax was not frozen until WMV 9.[1. While all versions of WMV support variable bit rate, average bit rate, and constant bit rate, WMV 9 introduced several important features including native support for interlaced video, non- square pixels, and frame interpolation.[1. WMV 9 also introduced a new profile titled Windows Media Video 9 Professional,[1. It is targeted towards high- definition video content, at resolutions such as 7. The Simple and Main profile levels in WMV 9 are compliant with the same profile levels in the VC- 1 specification.[1. The Advanced Profile in VC- 1 is implemented in a new WMV format called Windows Media Video 9 Advanced Profile. It improves compression efficiency for interlaced content and is made transport- independent, making it able to be encapsulated in an MPEG transport stream or RTP packet format. The format is not compatible with previous WMV 9 formats, however.[1. WMV is a mandatory video format for Plays. For. Sure- certified online stores and devices, as well as Portable Media Center devices. The Microsoft Zune, Xbox 3. Windows Mobile- powered devices with Windows Media Player, as well as many uncertified devices, support the format.[1. WMV HD mandates the use of WMV 9 for its certification program, at quality levels specified by Microsoft.[1. WMV used to be the only supported video format for the Microsoft Silverlight platform, but the H. Windows Media Video Screen[edit]Windows Media Video Screen (WMV Screen) are video formats that specialise in screencast content. They can capture live screen content, or convert video from third- party screen- capture programs into WMV 9 Screen files. They work best when the source material is mainly static and contains a small color palette.[1. One of the uses for the format is computer step- by- step demonstration videos. The first version of the format was WMV 7 Screen. The second version, WMV 9 Screen, supports VBR encoding in addition to CBR.[1. Additionally there is MSA1 (aka “MS ATC Screen codec” or “MSS3”) which is used in Live Meeting 2. Four. CCs for the formats are MSS1, MSS2 and MSA1.[1. Windows Media Video Image[edit]Windows Media Video Image (WMV Image) is a video slideshow format. The format works by applying timing, panning and transition effects to a series of images during playback.[2. The codec achieves a higher compression ratio and image quality than WMV 9 for still images as files encoded with WMV Image store static images rather than full- motion video. Since the format relies on the decoder (player) to generate video frames in real- time, playing WMV Image files even at moderate resolutions (e. The latest version of the format, WMV 9. Image, used by Photo Story 3, features additional transformation effects, but is not compatible with the original WMV 9 Image format.[2. Hardware support for WMV Image is available from Portable Media Centers, Windows Mobile- powered devices with Windows Media Player 1. Mobile.[1. 5]Since no known domestic DVD player supports this format, users of Photo Story 3 wishing to generate material capable of being played in a DVD player will first have to convert to MPEG- 2 before burning a DVD (average file sizes in MPEG- 2 are 5 to 6 times the .

Audio compression formats[edit]The audio format used in conjunction with Windows Media Video is typically some version of Windows Media Audio, or in rarer cases, the deprecated Sipro ACELP. Microsoft recommends that ASF files containing non- Windows Media formats use the generic . ASF file extension. Players[edit]Software that can play WMV files includes Windows Media Player, Real. Player, MPlayer, Media Player Classic, VLC Media Player and K- Multimedia Player.

Runtime environment. License. Proprietary[7]Websitewww. Adobe AIR (formerly Adobe Integrated Runtime) is a cross- platformruntime system developed by Adobe Systems for building desktop applications and mobile applications, programmed using Adobe Flash, Action. Script and optionally Apache Flex. The runtime supports installable applications on Windows, OS X and mobile operating systems including Android, i. OS and Black. Berry Tablet OS. It also originally ran on Linux, but support was discontinued as of version 2. Adobe AIR is a runtime environment that allows Adobe Flash content and Action. Script 3. 0 coders to construct applications and video games that run outside a web browser, and behave as a native application on supported platforms. An application developed for Flash Player or HTML5 and deployed in a browser does not require installation, while AIR applications require installation from an installer file (Windows and OS X) or the appropriate App Store (i. OS and Android). AIR applications have unrestricted access to local storage and file systems, while browser- based applications only have access to individual files selected by users.[8]Adobe AIR internally uses the Flash Player rendering engine and Action. Script 3. 0 as the primary programming language. Flash applications must specifically be built for Adobe AIR to use additional features provided, such as multi- touch, file system integration, native client extensions, integration with Taskbar or Dock, and access to accelerometer and GPS devices.[9] HTML5 applications may run on the Web. Kitengine included in AIR. Notable applications built with Adobe AIR include e. Bay Desktop, Pandora One desktop,[1. Tweet. Deck,[1. 2] the former Adobe Media Player,[1. Angry Birds,[1. 3] and Machinarium,[1. According to Adobe, over 1. AIR, and over 1 billion installations of the same were logged from users across the world, as of May 2. Adobe AIR was voted as the Best Mobile Application Development product at the Consumer Electronics Show for two consecutive years (CES 2. CES 2. 01. 5).[1. Features[edit]Using AIR, developers can access the full Adobe Flash functionality, including text, vector graphics, raster graphics, video, audio, camera, and microphone capability. Adobe AIR also includes additional features such as file system integration, native client extensions, desktop integration and access to connected devices. AIR enables applications to work with data in different ways, including using local files, local SQLite databases (for which AIR has built- in support), a database server, or the encrypted local store included with AIR. Developers can access additional functionality by building AIR Native Extensions, which can access full device functionality being programmed in the native language.[2. Desktop features[edit]On desktop platforms, AIR supports: Window management – Opening multiple windows, minimizing, maximizing and resizing AIR windows.[2. Menu bar – Adding a native menu bar to AIR windows, with sub menus and custom menu items.[2. File management – Discovering drives, files and folders on the PC, creating and deleting files, renaming, copying and moving files.[2. Console applications – Executing native applications with command- line arguments, and receiving feedback via standard I/O & error streams.[2. Multithreading – Managing multiple threads, to execute Action. Script 3 code in the background without freezing the user interface.[2. Web browser – View HTML web pages with full CSS and Java. Script support within Flash applications, with the integrated Web. Kit- based web browser.[2. Clipboard access – Programmatically copy or paste text, bitmaps or files into the system clipboard.[2. Drag- and- drop – Allows users to drag text, bitmaps or files into AIR applications.[2. Mobile features[edit]On mobile platforms, AIR supports many mobile hardware features: 3. D Graphics[edit]In 2. Stage. 3D to the Flash Player allowed Flash and AIR apps access to GPUs for hardware acceleration. Several third- party frameworks have been developed to build upon the functionality of Stage. D, including the Starling Framework and Away. D. These frameworks are also compatible with AIR, and provide vital performance improvements to AIR apps published for mobile devices. AIR Native Extensions[edit]AIR apps can be augmented in functionality with the usage of AIR Native Extensions (ANEs). Native extensions are plug- in code libraries that contain native code wrapped with an Action. Script API,[3. 3] allowing developers to access native features not otherwise usable in AIR, such as Apple Game Center or Google Cloud Messaging. Native extensions may be developed by anyone using publicly available tools; [3. Native extensions may be programmed in the native language on each platform, allowing access to the full set of platform APIs provided by the developer. C++ for Windows, Java for Android, Objective- C for i. OS).[2. 0]Availability[edit]AIR is a cross- platform technology and AIR applications can be repackaged with few or no changes for many popular desktop and mobile platforms. Different installation options exist for each platform. AIR applications may be published with or without the AIR runtime. Applications packaged with the AIR runtime are larger in file size, and are known as "captive runtime" applications.[3. If the runtime is not embedded in the app, it must be installed separately. In January 2. 00. Adobe claimed that there were over 1. Adobe AIR worldwide, and that "the majority of AIR runtime installations occur at the time the first AIR application is installed by a user".[3. In May 2. 01. 4, Adobe claimed that over 1. AIR, and over 1 billion installations of the same were logged from users across the world.[1. Desktop platforms[edit]The latest version of Adobe AIR, version 2. Adobe Flash Player 2. Windows 7 and later, as well as OS X 1. Official support for desktop Linux distributions ceased in June 2. Mobile platforms[edit]Adobe AIR applications can be published as native phone applications on certain mobile operating systems, such as Android (ARM Cortex- A8 and above[4. Applei. OS.[4. 5]Application development[edit]Adobe AIR runs Flash applications within a contained Flash Player instance. It runs web applications via Web. Kitrendering engine. Multiple instances of the browser can be started within a single AIR application, but Java. Script content executes with some security limitations. AIR does not provide direct access to native GUI elements such as navigation bars or controls. Native extensions can be used to access additional native resources. Development tools[edit]The AIR SDK is available as a free standalone download for software developers to make AIR applications.[4. SDK users do not need to install any commercial software to use the SDK, although several options are available. AIR apps can be compiled from the command line using the AIR compiler included in the SDK; the compiler can also be called from an IDE to eliminate the need for the command line. AIR can also be used with Adobe Flex.[4. Flex is an integrated collection of stylable graphical user interface, data manipulation and networking components, and applications built upon it are known as "Flex" applications. Flex GUIs are defined in MXML, similar to how Android and Microsoft Visual Studio define GUIs; however, Flex does not give access to native GUI components. AIR applications built without the Flex framework allow greater flexibility and performance, and are known as "pure Action. Script" applications.[4. Video games built on the AIR platform are typically pure- Actionscript projects. Various open- source component frameworks are available for pure Action. Script projects, such as Mad. Components, that provide UI Components at significantly smaller SWF file sizes.[5. Software[edit]Adobe distributes three commercial software products for developing of AIR applications in Action.
