IMSC test suites for the IMSC family of specifications.
Note that multiple tests, identified by the presence of the metadata element <ebuttm:conformsToStandard>urn:ebu:tt:distribution:2014-01</ebuttm:conformsToStandard>, conform to EBU-TT-D in addition to a profile of IMSC.
We thank the Institut für Rundfunktechnik (IRT) for providing the basis of multiple IMSC1 tests.
