DICOM Ballot Supplement 180 - Respond by May 25, 2015

Introduction to draft Supplement 180 (reproduced from the document for your convenience:)

This supplement describes three new Transfer Syntaxes to embed MPEG-4 Advanced Video Coding (AVC) / H.264 High Profile / Level 4.2 ([email protected]) and H.264 Stereo High Profile /Level 4.2 encoded pixel data in DICOM. It does not introduce any new SOP Classes or IODs.
Transfer Syntax MPEG-4 AVC/H.264 High Profile / Level 4.2 ([email protected]) for 2D Video will perform consistent with the ITU-T H.264 [email protected] specifications except that the use of frame packing formats for 3D video is not allowed. This will enable the storage of video files with a resolution of 1920x1080 at 50Hz/60Hz.

Transfer Syntax MPEG-4 AVC/H.264 High Profile / Level 4.2 ([email protected]) for 3D Video will perform consistent with the ITU-T H.264 [email protected] specifications. It should be used for transmitting stereoscopic 3D content with frame packing formats. This will enable the storage of 3D video files with a resolution of 1920x1080 at 50Hz/60Hz in frame packing format.

Transfer Syntax MPEG-4 AVC/H.264 Stereo High Profile /Level 4.2 will perform consistent with the ITU-T H.264 Stereo High Profile at Level 4.2. This will enable the storage of video files where higher compression can be achieved due to inter-view prediction. An example of the use would be in binocular operational microscopy.
This proposed supplement includes Addenda to existing Parts of DICOM:
- PS 3.5 Addendum: Data Structures and Encoding
- PS 3.6 Addendum: Data Dictionary
- PS 3.11 Addendum Media Storage Application Profiles
In the years since the DICOM Committee WG13 approved the new MPEG-4 AVC/H.264 Transfer Syntax with supplement 149, the capabilities of video recorders and video players have advanced considerably.
Support is required in DICOM for 2D and 3D video at 1080P 50/60 Hz as defined by MPEG-4 AVC / H.264 Level 4.2. Considerable space savings can be achieved when storing stereo recordings in Stereo High Profile format.
These three new transfer syntax will help to support advance technologies with an updated set of higher resolution, frame rates and compression capabilities. other imaging procedures, as well as templates with more required discrete data element content.
