Blu-Ray player through video mixer. Possible?
« on: August 21, 2012, 10:23:45 pm »

Working on a church install using a Panasonic AG-HMX100 digital video mixer.  Customer now wants to be able to use parts of commercial DVD's and Blu-Ray discs during presentations using the mixer.  It has HDMI in, no HDCP, and HD-SDI in. Got the M acBook Pro working fine with it and the cameras, but no luck with the Blu-Ray.  I know the HDCP is locking it out.  Any way to work around this?  Unit does not convert analog to digital, and all resolutions need to be the same. Would hate to have to take this back and get a different mixer.  Any help would be great.

There wont be a way you can get HDMI into the mixer from the bluray if it isn't HDCP compliant. You also wont be able to find an HDMI to HDSDI converter that supports HDCP signals as HDSDI is not an HCDP compliant signal.

Of course you can take the SD composite or component output from the bluray and convert it to HDSDI, but that wont look very good.

The most likely solution (other than swapping to a full HDCP compliant chain) will be to try something like the HDFury into a component to HDSDI converter. Its a far from ideal solution with a lot of conversions in the chain but its about the only way to keep the signal HD. I have never tried the HDFury products before so I cant comment on their reliability, and with the hassles around HDCP handshakes this could become an issue.

Failing that perhaps a bluray ripping program so they can take the sections of the discs they want and make them into a video file that will play as a non encrypted HD signal is a possibility? There is a lot of software available that can do this.


Hope this helps

This seems to be a hot topic recently.  The basic issue is that live production systems and the equipment intended for that market are focused on supporting live, original content where HDCP would not be relevant.  Theoretically, you should be able to play any non-protected content through the mixer, but since the mixer inputs are not HDCP compliant, not protected content.  Realistically, the HDCP standards address when content protection must be enabled but not when it must not be enabled, thus even non-protected content may be blocked if the source device manufacturer elected to enable HDCP beyond when required.
 
This might be a good application of one of the HD Fury devices as they are intended to convert non-HDCP compliant inputs into HDCP compliant inputs, but you'd have to see how well that works and converting from HDCP compliant HDMI to HD-SDI would still be prohibited as that would be creating a high resolution, unencrypted digital copy of the signal.
 
Another possible consideration, but you mentioned this involving "presentations".  The religious copyright exemption for public performances is related to the religious use and not to the venue being a church, thus the exemption applies only to worship services and not to use not directly related to worship.  Content before and after a service, movie nights, social gatherings, etc. are not covered under the religious use exemption regardless of it being a church or not.  So if the presentations involved include events other than worship services, copyrights and licensing are relevant and should be addressed.
