HI/VI
« on: October 06, 2018, 12:56:38 AM »
Evidently there's been some recent ADA legal activity surrounding compliance by way of the HI/VI systems at US theaters. The theaters are falling in line, but that means the pressure will shift to content providers. It's going to be incumbent upon those of us who encode these things to make sure it's done right.

In another thread I had mentioned that OpenDCP was placing rear surrounds in channels 7 and 8, which is not what most cinema servers are expecting (those are normally HI and VI). Has anyone actually made an HI-VI DCP with OpenDCP? Can you tell me where these two fall in terms of channel placement?

Also, this is a bit more important because it would appear that at least one of the HI/VI systems out there (Dolby's Fidelio) outputs nothing if channels 7 and 8 are empty. If this is true, I think it's a bit of a black eye on them, but still, it may be truer to DCI spec than "faking" HI from the existing audio in the first six channels.

Thanks.
