## D.5 Media Interchange

### D.5.1 Implementation Model

#### D.5.1.1 Application Data Flow

Figure D.5.1-1. Implementation Model

The application is a single pure Java application that provides a user interface, network support and media support as a File Set Reader.

Conceptually it may be modeled as the following single AE:

- MEDIA-FSR, which loads a user-selected PS3.10 compliant file, which may be a DICOMDIR or an image or spectroscopy object, either from the local file system or from PS3.12 compliant media according to one of the General Purpose Media Application Profiles of PS3.11 (CD-R or DVD-RAM)

In effect, the application is media-neutral, since the user is required to browse and locate the DICOMDIR file. Furthermore, any DICOM image or spectroscopy object encoded in one of the standard uncompressed Transfer Syntaxes may be loaded, even in the absence of a PS3.10 compliant meta-information header, in which case a "best guess" at the Transfer Syntax will be made.

Compressed Transfer Syntaxes are not supported, which limits the Media Application Profiles supported.

#### D.5.1.2 Functional Definitions of AEs

##### D.5.1.2.1 MEDIA-FSR

MEDIA-FSR is activated through the user interface to select directories, images and spectra for display, import into the local database or network transmission.

#### D.5.1.3 Sequencing of Real-World Activities

All FSR activities are sequentially initiated in the user interface, and another activity may not be initiated until the prior activity has completed.

### D.5.2 AE Specifications

#### D.5.2.1 MEDIA-FSR

MEDIA-FSR provides standard conformance to the Media Storage Service Class.

Table D.5.2-1. Application Profiles, Activities, and Roles for MEDIA-FSR

Application Profiles Supported | Real World Activity | Role
--- | --- | ---
STD-GEN-CD | Load directory or file | FSR
STD-GEN-DVD-RAM | Load directory or file | FSR

### Note

The application is media neutral and dependent on the underlying hardware. Any (non-secure) General Purpose Profile can be supported.

##### D.5.2.1.1 File Meta Information for the Application Entity

Not applicable, since MEDIA-FSR is not an FSC or FSU.

##### D.5.2.1.2 Real World Activities

###### D.5.2.1.2.1 Activity - Load Directory or File

MEDIA-FSR is activated through the user interface when a user selects the File load operation.

If the loaded file is a DICOMDIR, a browser will be displayed, from which instances may be selected and in turn loaded for display, imported into the local database or sent to a remote AE over the network.

If the file is an image or spectroscopy instance, it will be loaded and displayed.

###### D.5.2.1.2.1.1 Application Profile Specific Conformance

There are no extensions or specializations.

### D.5.3 Augmented and Private Profiles

#### D.5.3.1 Augmented Profiles

None.

#### D.5.3.2 Private Profiles

None.

### D.5.4 Media Configuration

None.
