Public Comments - DICOM Supplement 225 - Multi-Fragment Video Transfer Syntax

Hello All,

DICOM is seeking public comments for Supplement 225 - Multi-Fragment Video Transfer Syntax.

Scope and Field of Application
This supplement modifies existing video transfer syntaxes to remove the restriction that the video cannot be broken up into multiple fragments. The affected transfer syntaxes are:
• MPEG2 Main Profile / Main Level Video Compression
• MPEG2 Main Profile / High Level Video Compression
• MPEG-4 AVC/H.264 High Profile / Level 4.1 Video Compression
• MPEG-4 AVC/H.264 High Profile / Level 4.2 Video Compression
Videos of size larger than 2^32-4 bytes have started to appear (e.g. procedure video recordings). Previously, those videos needed to be split into multiple DICOM instances.
