Rights Commitment Table

  • Article

4/8/2010

Each application must notify the FDRM engine when to commit rights to be used. However, there is no requirement for applications to commit time-based rights. The user should be notified prior to using prompt-based rights. The following table shows the Microsoft recommendation for when an application should commit rights.

Content rights Description for ring tones, sounds, sound tracks, and video Description for images

Content preview for valid rights.

When an application plays a track or ring tone, rather than play the entire track, or ring tone, an application can play a short preview for the length of the preview time that is set in the Preview registry setting. This setting can be configured by the OEM.

  • If Preview = 0 seconds, then when an application plays a track or ring tone, that application plays the entire track, or ring tone. The application is required to verify the content rights and commit the rights before the content is used.
    For the preview of protected content with valid rights, an application can use the content. Microsoft recommends that the application does not suppress any rights commitment UI.
  • If Preview > 0 seconds then when an application plays a track or ring tone, the application plays the track or ring tone for the length of time specified by the value of the Preview registry setting. The application must verify the content rights prior to using the content. There is no requirement for the application to commit rights.

Ring tone settings and a media player are examples of applications that may preview content.

FDRM-protected thumbnails do not require rights commitment by the application.

If the preview is larger than a thumbnail, rights verification and commitment are required when FDRM-protected content is used.

Content preview for expired right.

Microsoft recommends that you do not allow an application to play, use, or view content when the content rights are expired.

Applications do not show a preview for thumbnails with expired rights.

Use content with no interruption.

Microsoft recommends that applications verify content rights and commit content rights before the content is used by the application.

Microsoft recommends that you allow an application to play, use, or view content with no interruption. Microsoft recommends that applications do not suppress rights commitment UI with the following exception:

Microsoft recommends that the rights commitment UI be suppressed if having the application wait for user input could result in the loss of some utility such as the ring tone handler on the Mobile-based device.

The recommendation for images is the same as for ring tones, sounds, sound tracks and video.

Use content, continue from a use interruption such as a pause or incoming call.

This content right usage does not apply to ring tones.

Microsoft recommends that if the application that uses an FDRM-protected ring tone, sound, sound track, or video is closed, the application verify and commit new rights as if a new session using the ring tone, sound, sound track, or video were starting.

If the application using the FDRM-protected ring tone, sound, sound track or video remains open and the content is not rewound, no rights verification or commitment is required.

  • The number of remaining count-based rights is not affected by an interruption in the playback or viewing of the content. Uses such as playback and viewing can continue.
  • For time-based rights, the application may continue using the media until the session is closed.

If the viewing application remains open and the content is rewound, rights verification and commitment are required when the application begins to use the content again.

  • For count-based rights, the application provides user notification prior to changing the prompt-based rights status if required. If user notification of changing is not required the application immediately uses content.
  • For time-based rights, further usage of the media by an application is prohibited if the time or count-based rights expired during the interruption of the content's use.

The recommendation for images is the same as for ring tones, sounds, sound tracks and video.

Content Use-expired rights

Microsoft recommends that you do not allow applications to preview the content with expired rights.

If content rights are expired Microsoft recommends that you do not allow applications to play, use, or view the content.

Applications do not show a thumbnail with expired rights.
