DRMManager

Package	flash.net.drm
Class	public class DRMManager
Inheritance	DRMManager EventDispatcher Object

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.5, Flash Player 10.1

The DRMManager manages the retrieval and storage of the vouchers needed to view DRM-protected content. With the static DRMManager.getDRMManager() method, you can access the existing DRMManager object to perform the following DRM-management tasks:

Preload vouchers from a media rights server, using a DRMContentData object.
Query the local cache for an individual voucher, using a DRMContentData object.
Reset all vouchers (AIR only)

No method is provided for enumerating all the vouchers in the local cache.

Do not create an instance of the DRMManager class. Use the static DRMManager.getDRMManager() to access the existing DRMManager object.

AIR profile support: This feature is supported on all desktop operating systems and AIR for TV devices, but it is not supported on mobile devices. You can test for support at run time using the DRMManager.isSupported property. See AIR Profile Support for more information regarding API support across multiple profiles.

Method Detail

addToDeviceGroup

()

method

public function addToDeviceGroup(deviceGroup:DRMDeviceGroup, forceRefresh:Boolean = false):void

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 3.0, Flash Player 11.9

adds the currently running device to a device group.

Parameters

	`deviceGroup:DRMDeviceGroup`

	`forceRefresh:Boolean` (default = `false`)

authenticate

()

method

public function authenticate(serverURL:String, domain:String, username:String, password:String):void

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.5, Flash Player 10.1

Authenticates a user.

Listen for the authenticationComplete and authenticationError events to determine the outcome of the authentication attempt. Multiple authenticate() calls are queued. The AuthenticationCompleteEvent object dispatched for the authenticationComplete event contains contains an authentication token that your application can save.

You can use a saved authentication token, or a token downloaded by another means, to establish an authenticated session with the media rights server in the future. To establish a session using a token, call the DRMManager setAuthenticationToken() method. The properties of the token, such as expiration date, are determined by the settings of the server that generates the token.

Important (AIR only): The authenticate() method will not succeed when a user's Internet connection passes through a proxy server requiring authentication. Although such users are not able to preload a DRM voucher that requires authentication, your application can obtain the voucher by beginning playback and using the NetStream setAuthenticationCredentials() method to log the user into both the proxy and the media rights servers. Once the voucher has been obtained, the user can view the content offline (as long as the license represented by the voucher allows offline playback).

Parameters

	`serverURL:String` — The URL of a media rights server that can provide a voucher for viewing protected content

	`domain:String` — A domain on the server (not a network or Internet domain name)

	`username:String` — The user name

	`password:String` — The user password

loadPreviewVoucher

()

method

public function loadPreviewVoucher(contentData:DRMContentData):void

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 2, Flash Player 10.1

Gets a preview voucher from the license server, which you can use to let a user verify that they can play content on particular computer. This capability lets users verify that they can play content on their computer before buying and downloading the content. It is useful when the user's computer doesn't have the necessary output protection capabilities or necessary software to play content.

Like loadVoucher(), this method is an asynchronous call and issues a DRMStatusEvent on completion or a DRMErrorEvent in case of errors.

Parameters

contentData:DRMContentData

loadVoucher

()

method

public function loadVoucher(contentData:DRMContentData, setting:String):void

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.5, Flash Player 10.1

Loads a voucher from a media rights server or the local voucher cache.

The voucher is loaded according to the setting parameter:

LoadVoucherSetting.FORCE_REFRESH: The voucher is always downloaded from the media rights server.
LoadVoucherSetting.LOCAL_ONLY: The voucher is only loaded from the local cache.
LoadVoucherSetting.ALLOW_SERVER: The voucher is loaded from the local cache, if possible, but otherwise is downloaded from the server.

The LoadVoucherSetting class defines string constants to use as values for the setting parameter.

When the voucher is successfully loaded, the DRMManager dispatches a DRM status event. Your application can begin playback as soon as the voucher is loaded. The loaded voucher is available in the voucher property of the dispatched DRMStatusEvent object. You can use this voucher object to display the associated media rights information to the user.

If a voucher cannot be loaded from the media rights server, a DRM error event is dispatched. The errorID property of the dispatched DRMErrorEvent object indicates the reason for the failure. Common causes of failure include attempting to connect to the media rights server when the user is offline and attempting to load a voucher when the user is not logged in. Your application can respond to these errors and take corrective action. For example, if authentication credentials are required to download the voucher, you can prompt the user for their account user name and password, call the DRMManager authenticate() method, and then attempt to load the voucher again.

If a voucher cannot be obtained from the local cache and the localOnly setting is used, a DRMErrorEvent is not dispatched. Instead, a DRM status event is dispatched. The detail property of this DRMStatusEvent object is still DRM.voucherObtained, but the voucher property is null.

Parameters

	`contentData:DRMContentData` — The DRMContentData object from a DRM-protected media file

	`setting:String` — Determines whether the voucher is retrieved from the local cache or the media rights server

removeFromDeviceGroup

()

method

public function removeFromDeviceGroup(deviceGroup:DRMDeviceGroup):void

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 3.0, Flash Player 11.9

Removes the currently running device from a device group.

Parameters

deviceGroup:DRMDeviceGroup

resetDRMVouchers

()

method

public function resetDRMVouchers():void

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.5, Flash Player 11.8

In AIR applications this deletes all locally cached digital rights management (DRM) voucher data. For browser based applications this is only available during 3322 errors, and behaves like the Protected Content Playback Settings panel.

The application must download the required vouchers again for the user to be able to access encrypted content. Calling this function is equivalent to calling Netstream.resetDRMVouchers().

Throws

IOError — The voucher data cannot be deleted.

returnVoucher

()

method

public function returnVoucher(inServerURL:String, immediateCommit:Boolean, licenseID:String, policyID:String):void

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 11.8, AIR 3.8

Returns to the license server all vouchers that match all specified criteria. When a voucher is returned, it is removed from on disk storage and from memory. This will not interrupt Netstreams and AVStreams that are currently using the returned vouchers for video playback, but will prohibit future playback. DRMManager will issue a DRMReturnVoucherCompleteEvent on success or a DRMReturnVoucherErrorEvent on error. Will throw an ArgumentError if inServerURL is null or if licenseID and policyID are both null.

Parameters

	`inServerURL:String` — The license server URLs from which the returned licenses were downloaded.

	`immediateCommit:Boolean` — Reserved. The only supported value is true.

	`licenseID:String` — (optional) Vouchers matching this licenseID will be returned. If null, policyID will be used instead.

	`policyID:String` — (optional) Vouchers matching this policyID will be returned. If null, licenseID will be used instead. If both licenseID and policyID are non-null, only a voucher that matches both licenseID and policyID will be returned.

setAuthenticationToken

()

method

public function setAuthenticationToken(serverUrl:String, domain:String, token:ByteArray):void

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.5, Flash Player 10.1

Sets the authentication token to use for communication with the specified server and domain.

Authentication tokens are available from the token property of the DRMAuthenticationCompleteEvent object dispatched after a successful call to the authenticate() method. The token is cached automatically for the session, but you can use the setAuthenticationToken() method to manage tokens directly.

Setting a token overwrites any existing cached token for the server and domain. Set the token parameter to null to clear the cached token.

Parameters

	`serverUrl:String` — The URL of the media rights server

	`domain:String` — The DRMContentData

	`token:ByteArray` — The authentication token

storeVoucher

()

method

public function storeVoucher(voucher:ByteArray):void

Language Version:
