This Technical Specification covers the off-line storage of biosignals, time-stamped measurements, events,
enumerations and alerts as expressed in the CEN/TC251 prestandard Vital Signs Information Representation
(ENV 13734). This Technical Specification defines a file data structure and not a message data structure.
This Technical Specification does not support data compression. This Technical Specification includes a
method to encapsulate or refer to one or many medical images, digital video and audio files but the intention
is neither to define a new format for medical or other images, video nor audio. Figure 1 defines the scope of
this Technical Specification with respect to ENV 13734.
In a small number of cases exact compatibility to ENV 13734 is not retained because of the chosen
encoding. An example of this is the data type AbsoluteTime of ENV 13734 which is replaced with the ISO
defined GeneralizedTime in this document (Section B.1.12).
Figure 2 defines the scope of this Technical Specification with respect to the archival subject in ENV 13734.
This Technical Specification does not address the specification of the multipatient archive nor the patient
archive. The ancillary object in this Technical Specification is the multimedia section.
