I found on a cinema drive an old DCP (encrypted of course). It has a lot of files with uuids but no assetmap, CPL, PKL, Volindex

It only has Chunk Files and Manifest files. The Manifest files list the chunks with their UUIDs and tell which video and audio files the chunks will create once rebuilt. It looks like a winrar/winzip spanned archive, but of course cannot be opened with winrar. The manifest files also set a sort of CompsotionPlaylist for each group of rebuilt files. There are also some keys for avica filmstore servers, so I guess those servers were capable to play that stuff. Anyone knows which is the name of that format and were can I find the specs? Or maybe manual and software upgrades of Avica Filmstore servers? Thanks a lot. I would buy one Avica Filmstore server just for the sake to look at that early product, can anyone tell me where can I find one on sale? Thanks a lot

It's quite possibly an MPEG-2 "Interop" format, rather than the current SMPTE spec - though I've never seen one to be sure about saying that.

I can't see the point in buying an old server to play it though, unless you're in a position to have a new key issued?

There's a chance to have a new key issued, I've got to ask the distributor. I would exclude MPEG2 MXF interop, as that format has Assetmap, CPL, PKL and MXF files but the video is MPEG2 Encoded. This one is MPEG2 encoded but the file extension is apf
