## 10.6 Transfer Syntax For JPEG 2000 Compression

One Transfer Syntax is specified for JPEG 2000 Image Compression (Lossless Only), and one Transfer Syntax is specified for JPEG 2000 Image Compression. Either of these may be negotiated separately and there is no default or baseline specified (other than described in Section 10.1).

### Note

1. All JPEG 2000 codecs are required by [ISO/IEC 15444-1] to support both reversible and irreversible wavelet and multi-component transformations. The reason for specifying two separate Transfer Syntaxes in DICOM is to allow an application to request the transfer of images in a lossless manner when possible. The JPEG 2000 Image Compression Transfer Syntax allows for either lossless or lossy compression to be used at the sender's discretion.

2. No baseline using other compression schemes is required.

3. When the pixel data has been received in the JPEG 2000 Image Compression Transfer Syntax, since it may have been lossy compressed, the waiver of the requirement in Section 10.1 to support the DICOM default Transfer Syntax still applies.

In addition, one Transfer Syntax is specified for JPEG 2000 Multi-component Image Compression (Lossless Only) with Multi-Component Transformation Extensions, and one Transfer Syntax is specified for JPEG 2000 Multi-component Image Compression with Multi-Component Transformation Extensions. Either of these may be negotiated separately and there is no default or baseline specified (other than described in Section 10.1).

### Note

JPEG 2000 codecs that support the Part 2 JPEG 2000 Multi-Component Transformation Extensions are required to support all the multi-component extensions as described in Annex J of [ISO/IEC 15444-2]. This includes both array based transformations and the 9-7 and 5-3 wavelet transformations that are also used in Part 1 of JPEG 2000. This also includes component reordering, component collections and application of more than one multi-component transformation in succession.
