DICOM PS3.5 2019b - Data Structures and Encoding

A.6 DICOM JPIP Referenced Transfer Syntax (Explicit VR)

This Transfer Syntax applies to the encoding of the entire DICOM Data Set. This Transfer Syntax shall only be used when Pixel Data (7FE0,0010) is present in the top level Data Set, and hence shall not be used when Float Pixel Data (7FE0,0008) or Double Float Pixel Data (7FE0,0009) are present. This implies that when a DICOM Data Set is being encoded with the DICOM Little Endian Transfer Syntax the following requirements shall be met:

  1. The Data Elements contained in the Data Set structure shall be encoded with Explicit VR (with a VR Field) as specified in Section 7.1.2.

  2. The encoding of the overall Data Set structure (Data Element Tags, Value Length, and Value) shall be in Little Endian as specified in Section 7.3.

  3. The encoding of the Data Elements of the Data Set shall be as follows according to their Value Representations:

    • For all Value Representations defined in this Part, except for the Value Representations OB and OW, the encoding shall be in Little Endian as specified in Section 7.3.

    • For the Value Representations OB and OW, the encoding shall meet the following specification depending on the Data Element Tag:

      • Pixel Data (7FE0,0010) shall not be present, but rather pixel data shall be referenced via Data Element (0028,7FE0) Pixel Data Provider URL

      • Overlay data, if present, shall only be encoded in the Overlay Data (60xx,3000) Element, which shall have the Value Representation OB or OW and shall be encoded in Little Endian.

      • Data Element (0028,0004) Photometric Interpretation shall be limited to the values: MONOCHROME1, MONOCHROME2, YBR_ICT and YBR_RCT.

This DICOM JPIP Referenced Transfer Syntax shall be identified by a UID of Value "1.2.840.10008.1.2.4.94 ".
