PlayReady is a media file copy prevention technology from Microsoft that includes encryption, output prevention and digital rights management (DRM). It was announced in February 2007.^[1]

The main differences relative to previous DRM schemes from Microsoft are:

Tech support scams are an industry-wide issue where scammers trick you into paying for unnecessary technical support services. You can help protect yourself from scammers by verifying that the contact is a Microsoft Agent or Microsoft Employee and that the phone number is an official Microsoft global customer service number. 2019-4-2  By including Microsoft's PlayReady DRM, the Chromium-based Edge will be able to to play Netflix videos at both 1080p HD and 4K UHD resolutions. Mac, and Linux. Up to 1080p on Chrome OS.

For the Windows 8.1 reference, see Developing PlayReady Windows Store and Web Apps. PlayReady on Window 7, MacOS. Some Microsoft Partners provide SDKs to run PlayReady on Windows 7 and Mac OS, based on Electron, Xamarin, or other technologies. You can contact these PlayReady Partners directly for more information. Azure Media Player easily integrates into web and app solutions, supports most popular devices, and uses familiar JavaScript API development. Get started today. Media Player supports content secured with DRM technology, through Microsoft PlayReady and Widevine, or Advanced Encryption Standard (AES) 128-bit clear-key encryption.

• Some popular features that were already present in other DRM schemes in the market have been added; these include the concept of domain (group of devices belonging to the same user which can share the same licenses), Embedded Licenses (licenses that are embedded in the content files, avoiding a separate step for license acquisition) and envelopes (the ability to DRM arbitrary, potentially non-media content). It is also the protection scheme for IIS Smooth Streaming, Microsoft's adaptive streaming technology.
• It is platform-independent: unlike other Microsoft DRM schemes like Janus, PlayReady can be ported to any kind of portable device, even if it uses non-Microsoft technology (OS, codecs, media player, etc.).

PlayReady is a Digital Rights Management from Microsoft for portable devices. PlayReady can be ported to any kind of portable device, even if it uses non-Microsoft technology (OS, codecs, media player).

PlayReady competes with other proprietary DRM schemes and even more with DRM-free software, most notably Apple's FairPlay introduced in iTunes and QuickTime. There are several other DRM schemes that are competing to become the dominant DRM technology (e.g. Widevine).

Microsoft released the first version of the PlayReady suite (Porting Kit for devices, PC SDK and runtime, Server SDK) in June 2008. Silverlight 2.0, released in October 2008, supports content restricted with PlayReady. As of Silverlight 4.0, the implementation of Microsoft PlayReady in Silverlight supports offline content (via persisted license), subscription scenarios (via chained licenses) and online, streaming-only content (via simple non-persistent licenses). Output protection support was also added in Silverlight 4.0.

Interoperability[edit]

• PlayReady 2.9 and below is backwards compatible with Windows Media DRM 10 content, meaning that content encrypted with WM DRM 10 (for instance, content for PlaysForSure devices) will play on a PlayReady terminal.
• PlayReady will no longer be compatible with PlayReady 3.0 and above.^{[clarification needed]}
• PlaysForSure compliant devices won't play PlayReady-encrypted content.^{[clarification needed]}

Devices including a PlayReady Client embedded by the OEM

Microsoft Playready Test Player

Many leading OEMs have licensed PlayReady and have implemented a player (based on the PlayReady Porting Kit) into their devices. They then make it available to application developers as part of their SDK.

For example, Microsoft ensures all Windows 10 devices include a PlayReady Client integrated in the Windows OS itself, or in the chip's firmware of the device (TEE), and exposes it through UWP APIs to application developers. But many Android TV device makers do the same. These devices use various APIs to expose the PlayReady Client to applications, including:

• The Universal Windows Platform API on PCs, Xbox
• The Java DrmManagerClient API on Android devices
• Various interfaces on Linux devices
• The Javascript EME API on modern web browsers
• The CE-HTML HbbTV API on old embedded web browsers

On these devices, application developers do not need to license PlayReady, or manipulate the PlayReady code or certificate. Microsoft boot camp mac download. They just use the SDK provided by the OEM on the platform and run PlayReady operations from within their app, like AcquireLicense(KID), and so on.

An application developed with this model is not royalty-bearing.

The following table shows the current availability of a PlayReady Client on various devices.

Devices not including a PlayReady Client

Microsoft Playready Mac Free

Some OEMs have made the choice to not embed a PlayReady Client in their device, or to embed it but not make it available to application developers through their SDK.

On these devices, application developers can still run PlayReady operations from within their app, but they need to integrate the PlayReady Client in their application, including PlayReady code and certificates.

The integration of a PlayReady Client in the application requires the application developer to license PlayReady and use an implementation based on the PlayReady Device Porting Kit in the application. A company that develops using PlayReady source code must hold a PlayReady Device Development and Intermediate Product Distribution License.

This development requires expertise to harden the application, including the PlayReady code and the PlayReady secrets (keys, certificates). Most application developers decide to use a PlayReady SDK developed and maintained by a Microsoft Partner).

Developing Applications using PlayReady on Windows, Xbox

Microsoft develops and distributes a PlayReady Client in every Windows 10, 8.1, 8 unit, and in every Xbox unit. This PlayReady Client is exposed and freely accessible through a high-level API to application developers.

Application developers can create Universal Windows Platform (UWP) applications capable of providing PlayReady content to the user while enforcing the access rules defined by the content provider. An application can freely use this built-in PlayReady Client in Windows 8, 8.1, or 10, without signing any agreement with Microsoft, and without the need of any PlayReady certificate, or any PlayReady fee or royalty due.

Windows 10 PlayReady documentation can be found at PlayReady for Windows 10 and at Windows.​Media.​Protection.​Play​Ready Namespace . Samples of PlayReady Windows 10 applications can be found as part of the UWP Samples collection and at PlayReady sample Universal Windows Apps for Windows 10 (Javascript/C#/EME).

To learn more about designing an application that runs on Xbox, see PlayReady DRM on Xbox.

You can also create PlayReady Windows Store and Web applications for Windows 8.1. Windows 8.1 PlayReady documentation can be found at Developing PlayReady Windows Store and Web Apps. Samples of PlayReady Windows 8.1 applications can be found at PlayReady sample for Windows 8.1 Store apps.

Developing Applications using PlayReady on Windows 7

Some PlayReady Partners provide SDKs to run PlayReady on Windows 7 and Mac OS, based on Electron, Xamarin, or other technologies. You can contact these PlayReady Partners directly for more information.

Silverlight is a deprecated application framework running on Windows 7 and Mac OS that includes a fully functional PlayReady Client. It runs in browsers with limitations, and can also run out of browsers to provide standalone apps on Windows 7 and Mac OS.

Developing Applications using PlayReady on Android

While many Android device models embed a PlayReady Client integrated by the OEM, others do not.

Microsoft Playready Machine

Developing an application for the models which embed one is as simple as using the SDK from these devices. They will typically expose the PlayReady Client through the Java DrmManagerClient class. See the PlayReady Plugin for Android Microsoft Specification for more information.

Developing an application for the models which don't embed a PlayReady Client requires the integration of the PlayReady Client in the application itself.

Microsoft Partners develop PlayReady SDKs for Android from the PlayReady Porting Kit, and make them available to application developers. If you have a project to develop an application using PlayReady on Android, you can directly contact the listed Microsoft Partners for proposals and quotes.

Developing Applications using PlayReady on iOS, AppleTV OS, MacOS

Apple products do not ship with an embedded PlayReady Client. However, it is possible to distribute applications for these platforms that integrate a PlayReady Client in the application itself.

Microsoft Partners can also develop PlayReady SDKs for Apple-based OS platforms from the PlayReady Porting Kit, and make them available to application developers. If you have a project to develop an application using PlayReady on iOS for example, you can directly contact the listed Microsoft Partners for proposals and quotes.
