Clarify SMPTE Transfer Syntaxes for DICOM Web Services The application/dicom media type specifies a representation of Instances encoded in the DICOM File Format specified in . The origin server may populate the File Meta Information with the identification of the Source, Sending and Receiving AE Titles and Presentation Addresses as described in , or these Attributes may have been left unaltered from when the origin server received the objects. The user agent storing the objects received in the response may populate or coerce these Attributes based on its own knowledge of the endpoints involved in the transaction, so that they accurately identify the most recent storage transaction. specifies the default and optional Transfer Syntax UID combinations for each DICOM Resource Category (see ). The default media type for the Resource Category shall be returned when the origin server supports none of the Acceptable Media Types, unless the origin server has only access to the pixel data in lossy compressed form or the pixel data in a lossless compressed form that is of such length that it cannot be encoded in the Explicit VR Little Endian Transfer Syntax.

The SMPTE ST 2110-20 Uncompressed Progressive Active Video Transfer Syntax is not included, since it is only used in a DICOM-RTV Metadata Flow, rather than in a representation of an Instance encoded in the DICOM File Format.
