Dolby E HDCAM channel order?
on Jul 30, 2009 at 9:25:16 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)


Production Premium CS4 - Mocha v1.2.3 - FCP 5.1.4
MacPro Quad 3GHz / ATI 1900XT / 8GB RAM / OSX 10.4.11
30" ACD / Decklink SP / SONY PVM-20M4E/ Wacom Intuos 3 A4 / XServe / United Digital RAID
Production Premium CS2 - Combustion 3 - Mocha v1.0.1
Win XP Pro 32 / Dell Precision T3400 Q6600 / 4GB RAM / NVidia Quadro570 / DeckLink Pro / Roland DS-5s / Sony BVM-20G1E / 2 x Dell 2007FP / Wacom Intuos 3 A4 / 320GB boot/800GB RAID-0

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.
