are nearly ready for our broadcast applications,
and the EBU, the DPP and the NABA are working
with SMPTE to define the final IMF application to
support the global broadcast requirements. IMF
currently defines the core, what constitutes an
IMF file and how to construct one, what metadata
must be included and the labeling conventions for
the audio and subtitles. Since the EBU already has
a standardized Television distribution specifica-
tion, there is a likelihood that a different codec
will be required for the OPL construction of the
Broadcast IMF application files, and the working
groups defining these characteristics are care-
ful to constrain the codecs to specific operating
parameters in order to keep the files complaint
and interoperable.
The industry still needs broadcast leadership in
order to make this dream of interoperable files
come true. Input from real broadcast engineers
and managers is needed to complete the speci-
fication and questions still persist; for example,
there is an understanding that we do need addi-
tional, broadcast specific metadata for the televi-
sion version description. And for real efficiencies,
the IMF files should address the broadcast plant’s
automation systems as a key component of a suc-
cessful solution. By providing the automation sys-
tems and back office tools such as traffic software
with key metadata, the IMF files could streamline
current operations and again save labor and time.
