Re: [DCP-o-matic] Failed SMPTE validation on Sony projector

It would be necessary to know what type of Sony projectors are used. There are two major product versions with very different software when it comes to SMPTE DCPs. The Sony SMPTE verification is not just a hash check. Also, the trouble DCP-o-matic had with Sonys was ONLY with encrypted SMPTE DCPs. It wasn't possible to create working KDMs for them - unencrypted SMPTE DCPs would always ingest and play fine. This issue was finally solved both in DCP-o-matic, and a Sony software update (it was actually a bug on Sonys side, not DCP-o-matic). The DCP was okay, the trouble was with the certificate/signature validation. Now, the older Sony SRX-R220/320 systems have a separate SMPTE validation process. It is usually triggered after ingest automatically, but manual is possible as well. The more modern SRX-R5xx/8xx systems perform that validation in the background/during ingest. These are the systems with the validation/signature bug that later had been solved. On the R5xx/8xx systems, it is very easy to find the software version number, it is always displayed on the lower right of the screen. See screenshot. It is also comprehensive - the number tells the version of all software components, Server, projector, subsystems, etc. Make them send a photo of the main screen with the lower right visible. It may be that the older R320 systems have trouble with some aspects of SMPTE Bv2.1. They haven't received software updates for a long time. They will certainly still play SMPTE DCPs, but it may be that commercial DCP mastering companies found ways around their issues. I know a few people still operating these older Sonys, but they are not ready to play tests. I have another report of a SMPTE DCP not working or not ingesting on a SONY, but in that case, even less information is available. It could also be a disc format issue. I create SMPTE DCPs for our Sony R515 multiple times each week. I never had issues. - Carsten
