The Offline-Media Application Entity exports images and Presentation States to a CD-R Storage medium. It is associated with the local real-world activity "Export to CD-R". "Export to CD-R" is performed upon user request for selected patients, studies, series or instances (images or presentation states).
Activation of the "Export to CD-R" icon or menu entry will pass the currently selected patients, studies, series or instances (images or presentation states) to the Offline-Media Application Entity. The SOP Instances associated with the selection will be collected into one or more export jobs. The contents of each export job will be written to a single CD-R media.
At least one image or presentation state must exist and be selected before the Offline-Media Application Entity can be invoked. The operator can insert a new CD-R media at any time before or after invocation of the Offline-Media Application Entity. The Offline-Media Application Entity will wait indefinitely for a media to be inserted before starting to write to the CD-R device. If no CD-R media is available the export job can be canceled from the job queue.
The Offline-Media Application Entity provides standard conformance to the Media Storage Service Class. The Application Profiles and roles are listed below:

The Source Application Entity Title included in the File Meta Header is configurable (see Section B.5.4).
The Offline-Media Application Entity acts as an FSC when requested to export SOP Instances from the local database to a CD-R medium.
A dialogue will be presented allowing the user to modify the suggested media label and provides control over the available media capacity. If the contents of the current selection do not fit on a single media an automatic separation into multiple export jobs will be suggested that can be adapted by the user.
The user will be prompted to insert an empty CD-R for each export job. The contents of the export job will be written together with a corresponding DICOMDIR to a single-session CDR. Writing in multi-session mode is not supported. The user can cancel an export job in the job queue.
The Offline-Media Application Entity support the STD-GEN-CD Application Profile.
