Rights for Playing and Copying
By using the following rights, you can control the use of protected Windows Media-based content:
Playcount. This right specifies the number of times the consumer is allowed to play protected content. By default, this right is not set and unlimited playing is allowed.
AllowCopy. This right allows consumers to copy protected content to a device, such as a portable player or portable media, that supports Windows Media DRM 10 for Portable Devices. Typically, when content is copied to a device, a new license is created on the device. By default, this right is not enabled.
CopyCount. This right specifies the number of times the consumer is allowed to copy content using the AllowCopy right. By default, this right is not set, and unlimited copies are allowed.
AllowTransferToNonSDMI. This right allows the consumer to transfer the Windows Media file to a device that supports Portable Device DRM version 1 or Windows Media DRM 10 for Portable Devices. By default, this right is not enabled.
AllowTransferToSDMI. This right allows the consumer to transfer the Windows Media file to a device that supports Portable Device DRM version 1 or Windows Media DRM 10 for Portable Devices. By default, this right is not enabled.
TransferCount. This right specifies the number of times a consumer can transfer a Windows Media file to a device using the AllowTransferToNonSDMI and AllowTransferToSDMI rights. By default, this right is not set, and unlimited copies are allowed.
AllowBackupRestore. This right allows the consumer to manage licenses by making backup copies and restoring licenses from backups. Consumers can restore licenses to the same computer (such as when a consumer reformats a computer) or to different computers (such as a work computer and a home computer).
The Microsoft License Management Service discourages fraudulent use of licenses, manages the restoration operation, and enforces business rules that prevent a consumer from abusing content. Consumers can store licenses on up to four computers, meaning they can restore licenses three times (on three computers other than the one to which the license was issued). If an attempt is made to restore licenses to a fifth computer, a Web page describing the limit is displayed.
Note If you allow counted operations in a license, you should not grant the AllowBackupRestore right because restoring the license also restores the original limits of the operations. For example, suppose you allow 10 plays. The consumer plays the Windows Media-based content nine times, and then backs up and restores the license. Now, the restored license allows an additional 10 plays, which is not what you intended.
By default, the AllowBackupRestore right is not enabled.
AllowCollaborativePlay. This right allows consumers play protected content in a collaborative session using peer-to-peer services. For example, users of MSN Messenger 2004 can play protected content in a MusicMix session. The consumer can only contribute the protected content to one group of listeners at a time, and all listeners must be online to play the content. By default, this right is not enabled.
AllowPlaylistBurn. This right allows consumers to copy a Windows Media file from a playlist to a CD in the Red Book audio format. However, after a Windows Media file is copied to a CD, the Windows Media file is no longer protected. By default, this right is not enabled.
If AllowPlaylistBurn is enabled, you can use the following rights to restrict the number of times a Windows Media file is copied:
- MaxPlaylistBurnCount. The maximum number of times a Windows Media file can be copied to a CD as part of a particular playlist. If the playlist is modified (for example, the tracks are arranged in a different order, or a track is added or removed), the playlist is considered new and this count is reset. By default, this right is not set and there is no limit.
- PlaylistBurnTrackCount. The maximum number of times a Windows Media file can be copied to a CD, regardless of what playlist it is in. By default, this right is not set and there is no limit.
For example, in the license for TrackABC, AllowPlaylistBurn has been enabled, MaxPlaylistBurnCount has a value of 10, and PlaylistBurnTrackCount has a value of 20. This means TrackABC can be burned a total of 20 times and can be burned in the same playlist up to 10 times. So, a user could burn TrackABC in a minimum of two different playlists or in a maximum of twenty different playlists.
