  • Dolby E HDCAM channel order?

    Posted by Jimmy Brunger on July 30, 2009 at 9:25 am

    Hi all,

    Hoping someone can clarify something…we have a debate running about the ‘standard’ channel order for a Dolby E stream delivered as data tracks on a HDCAM tape.

    I am being told the defacto standard is (1-6) L,R,C,LFE,Ls,Rs.

    However I have a facility saying L,C,R,Ls,Rs,LFE is a recognised standard for broadcast.

    Can anyone confirm the latter statement?

    (I know – we should just ask the broadcaster for specific tech specs, but we did that and got nothing back, so this is a retrospective query)

    Cheers,
    Jim.

    Hi Jim,

    LCR is the film standard, LRC is the SMPTE standard. The difference was designed to confuse everyone and foster many debates about which is correct. I think LRC was developed to maintain consistency with stereo formats, with the first 2 tracks always being LR.

    No one has been able to sufficiently explain this to me so, for HDcam masters, I ship my tracks L,C,R,Ls,Rs,Lfe. And subsequently, no one has ever called me to tell me I’m a buffoon.

    Perhaps some of our other members can shed some additional light. I’m interested, as well.
