Multiplex Group Time Offset Attribute

Tag(0018,1068)
TypeConditionally Required (1C)
KeywordMultiplexGroupTimeOffset
Value Multiplicity1
Value RepresentationDecimal String (DS)

Offset time in milliseconds from a reference time (see Section C.10.9.1.1).

Required if Acquisition Time Synchronized (0018,1800) value is Y; may be present otherwise.

Section C.10.9.1.1

C.10.9.1.1 Multiplex Group Time Offset

Multiplex Group Time Offset (0018,1068) specifies the offset time in milliseconds from a reference time to the first sample of the multiplex group. The reference time is Acquisition DateTime (0008,002A), if present in the SOP Instance.

In all other cases, the offset is from an arbitrary reference time that is the same for all Multiplex Groups in the SOP Instance; i.e., the Multiplex Group Time Offset allows only relative time synchronization between Multiplex Groups in the SOP Instance. The arbitrary reference time may nominally be assumed to be Content Time (0008,0033).
