EBU Segmentation document

All,

As per Action-235 please see this draft document on segmentation of EBU-TT, for reference with respect to Issue-288. Note that it is not finalised within EBU and may be published as a purely informative document rather than a normative one. There is therefore no formal errata document, however some areas have been commented on and may change, including the substantive change described below.

Section 4.1.5 states that content outside a sample's temporal extent shall not be displayed. However in the draft EBU-TT-D specification it is permitted in fault scenarios for processors to make use of the knowledge of any subtitles that extend outside the sample's temporal extent to be displayed, as a 'graceful recovery' option only, in the case that the sample that should be active has not been received.

Kind regards,

Nigel
