  6. Proposedextentionof SEG-D • Proposal: Add support for little-endian samples • Rationale: • Modern acquisition system (and processing systems) mostly uses little-endian CPUs • Converting to and from big-endian samples costs a lot of processing time and increases the cost of the systems • Comment: This only really applies to sample formats which maps directly to a CPU data type. Formats like 8015 or 8036 will not benefit much.

  7. Proposedextentionof SEG-D Technical proposal: • Add new series of sample format codes, e.g. 90xx 9058 = Little-endian 4 byte IEEE float value.

  8. Proposedextentionof SEG-D Questions: • Is this a good idea? • Can this be done as part of current SEG-D rev 3.0? Or do we need a format update? • The latter requires a longer process

  9. SEG-Y Rev 2.0 • Stewart Levin (salevin@alumni.princeton.edu) heading team • Primarycurrentactivityof TSC • Lots of industry interest • Working documentswww.seg.org/tsc - Documents/Format Development/SEG-Y/SEG-Y Rev 2.0 • Forumwww.seg.org/tscForum/SEG-Y/SEG-Y Revision 2 Working Group
