WMRMRights.PlayRestrictions
The PlayRestrictions property specifies and retrieves a string that indicates which technologies can or cannot be used to play protected content.
Syntax
WMRMRights.PlayRestrictions = String String = WMRMRights.PlayRestrictions
Parameters
This property takes no parameters.
Return Values
If the property succeeds, it returns a String containing the play restrictions. If it fails, it returns a number in the error object.
Remarks
You can use the WMRMRestrictions object to specify the technologies to require, include, or exclude for playing protected content. For example, you can require that all digital audio content be played back on applications and devices with at least obfuscation technology (a protection level of 200). By default, playback restrictions are not set.
For information about current output protection levels, see the document WMRM SDK Compliance Rules that accompanied your license agreement from Microsoft.
Example Code
' Set playback and copy restrictions.
Dim RestrictObj ' WMRMRestrictions object
Dim PlayRestrictions ' Playback restrictions
Dim CopyRestrictions ' Copy restrictions
Set RestrictObj = Server.CreateObject("WMRMObjs.WMRMRestrictions")
' Set output protection levels for playback.
Call RestrictObj.AddRestriction(1, 300) ' Uncompressed digital video
Call RestrictObj.AddRestriction(2, 500) ' Compressed digital video
Call RestrictObj.AddRestriction(3, 200) ' Analog video
Call RestrictObj.AddRestriction(4, 200) ' Compressed digital audio
Call RestrictObj.AddRestriction(5, 200) ' Uncompressed digital audio
' Add an extended technology for playing analog video.
Call RestrictObj.AddExtension("{C3FD11C6-F8B7-4d20-B008-1DB17D61F2DA}", 1)
' Get the playback restrictions string.
PlayRestrictions = RestrictObj.GetRestrictions
' Set output protection levels for copying.
Set RestrictObj = Nothing
Set RestrictObj = Server.CreateObject("WMRMObjs.WMRMRestrictions")
Call RestrictObj.AddRestriction(6, 400) ' Copied output.
' Get the copy restrictions string.
CopyRestrictions = RestrictObj.GetRestrictions
' Set the restrictions in the WMRMRights object.
