H General Purpose DVD With Compression
Interchange Profiles (Normative)
H.1 Profile Identification
This Annex defines an Application Profile Class potentially inclusive of all defined Media Storage SOP Classes. This class is intended to be used for the interchange of Composite SOP Instances via DVD media for general purpose applications. Objects from multiple modalities may be included on the same media. Images may be compressed with or without loss using either JPEG or JPEG 2000; all File Set Readers are required to support decompression of all of the compressed Transfer Syntaxes defined for each Profile.
A detailed list of the Media Storage SOP Classes that may be supported is defined in PS3.4.

Equipment claiming conformance to this Application Profile shall list the subset of Media Storage SOP Classes that it supports in its Conformance Statement.
Note
Since it is not required to support all Media Storage Classes the user should carefully consider the subset of supported Media Storage SOP Classes in the Conformance Statements of such equipment to establish effective object interchange.
H.2 Clinical Context
This Application Profile Class facilitates the interchange of images and related data on DVD media. Typical interchange would be between acquisition devices, archives and workstations.
ThisApplicationProfileClassfacilitatesthecreationofamulti-modalitymediumforimageinterchange,usefulforclinical,patientrecord, teaching and research applications, within and between institutions.
This profile is intended only for general purpose applications. It is not intended as a replacement for specific Application Profiles that may be defined for a particular clinical context.
Note
The creation of a DVD is considerably more complex than the reading thereof. Therefore the clinical context for this Applic- ation profile is likely to be asymmetric, with a sophisticated File Set Creator and relatively simple File Set Readers.

H.2.1 Roles and Service Class Options
This Application Profile Class uses the Media Storage Service Class defined in PS3.4.
The Application Entity shall support one or more of the roles of File Set Creator (FSC) or File Set Reader (FSR), defined in PS3.10. The File Set Updater (FSU) role is not defined.
H.2.1.1 File Set Creator
The role of File Set Creator shall be used by Application Entities that generate a File Set under this Image Interchange Class of Ap- plication Profiles.
FileSetCreatorsshallbeabletogeneratetheBasicDirectorySOPClassintheDICOMDIRfilewithallthesubsidiaryDirectoryRecords related to the Image SOP Classes stored in the File Set. The Application Entity acting as a File Set Creator generates a File Set under a STD-GEN-DVD or STD-GEN-SEC-DVD Application Profile.
FSCshalloffertheabilitytoeitherfinalizethephysicalvolumeatthecompletionofthemostrecentwritesession(noadditionalinform- ation can be subsequently added to the volume) or to allow multi-session (additional information may be subsequently added to the volume). An FSC may allow packet-writing, if supported by the media and file system specified in the profile.
Note
A multiple volume (i.e., a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume (side of one piece of media), the FSC will create multiple independent DICOM File Sets such that each File Set can reside on a single physical volume (side of a single piece of media) controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).
H.2.1.2 File Set Reader
The role of File Set Reader shall be used by Application Entities that receive a transferred File Set under the Image Interchange Class of Application Profiles. Typical entities using this role would include image generating systems, display workstations, and archive systems that receive a patient record; e.g., transferred from another institution.
File Set Readers shall be able to read the DICOMDIR directory file and all the SOP Instance files defined for this Application Profile, for which a Conformance Statement is made, using all the defined Transfer Syntaxes for the Profile.
Note
All Transfer Syntaxes defined in the profile must be supported by the FSR. It is not permissible to only support one or other of the uncompressed or the compressed Transfer Syntaxes.
H.2.1.3 File Set Updater
The FSU role is not defined for the STD-GEN-DVD and STD-GEN-SEC-DVD profiles.
H.3 STD-GEN-DVD and STD-GEN-SEC-DVD Profile Classes
H.3.1 SOP Classes and Transfer Syntaxes
This Application Profile is based on the Media Storage Service Class (see PS3.4).

H.3.5 Security Parameters
The STD-GEN-SEC-DVD application profiles require that all DICOM Files in the File-set including the DICOMDIR be Secure DICOM Files encapsulated in accordance with the requirements of the Basic DICOM Media Security Profile as defined in PS3.15.
Note
These Application Profiles do not place any consistency restrictions on the use of the Basic DICOM Media Security Profile withdifferentDICOMFilesofoneFile-set.Forexample,readersshouldnotassumethatallFilesintheFile-setcanbedecoded by the same set of recipients.
