Dear All,

I'm helping my colleagues at the National Library of Korea with translating
the latest updates to MARC21, but we are stumbling a bit with control field
008, characters 35-37 (language). There it states that: 

"For visual materials, coding depends on the type of material. For moving
image materials, the language content is defined as the sound track, the
accompanying sound, or sign language. For moving image materials with no
sound or sign language content or, if with sound, no narration, use zxx (no
linguistic content)." (http://www.loc.gov/marc/bibliographic/bd008a.html).

Seeing as how neither I or the colleague I'm working with have experience
with cataloging visual or moving image materials, we are struggling to
understand the difference between "sound track" and "accompanying sound",
and to of course translate this to Korean. 

Those of you with experience with this, how do you understand the difference
between sound track and accompanying sound as it applies to moving images?
Is sound track, accompanying sound, and sign language essentially equivalent
to sound, narration, and sign language, as the remainder of the paragraph
seems to suggest? As a sole consumer of moving images, I only understand
soundtrack to mean the music or song accompanying a moving image. Field 41
also addresses language, and defines "accompanying sound" for audivisual
materials generally to be "discs, tapes, etc", but what would that mean for
moving images?

Any help or insight would be much appreciated!
