What does Best Buy use for its store HD signal?

I see that Best Buy uses coaxial input on its store TV displays and they are playing a Best Buy dedicated program. Is this a feed off of a satellite program dedicated for in-store use?

Are they playing a Blu Ray disc or other HD signal source converted to an ATSC signal (similar to DVD player RF modulation)? If so, how?

I'm not interested in the programming, rather the methods of large-scale single-source deployment. HDMI distribution is too unreliable for us so far.

Thanks

We are using Blu Ray as the source, and in some trade shows, OTA signal can be tricky inside arenas, so no OTA. We need to display multiple TVs from one player. We have a few different setups, one that will be in the 30 TV range and one in the 15-20 TV range.

We have HDMI boxes ran daisy-chained but this is un-reliable (start up can be messy and handshake hiccups during playback happen from time to time).

I'm not familiar with Sencore, do they make something that would take HD source (BD or even a hard drive w/h.264 or similar playback) and output an ATSC modulated signal?

Lots of great info here everyone. Thanks!

We're not looking to show the TV receiver, just to show off the display itself, so picture quality is key. 1080P is the goal, however, unless I am missing something, that won't be possible other than via Blu-ray over HDMI.

I did confirm, locally, that the Wal-Mart & Sam's Club use Component Video, however, I could not see what specific hardware was in use. I'd prefer not to go this route due to the bulky cabling involved. Single HDMI or coax cable is more appealing from an installation standpoint.

Our source material will be a standard BD, no original HD video content for the near future, so I need to make sure that there are no encryption concerns for conversion to QAM or ATSC/8VSB.

Thanks!

I heard back from Blonder Tongue about the HDE-QAM. This has HDMI IN w/HDCP, so I could connect easily from BD player. Downside is only 1080i output. This may not be a deal breaker, depending on how important 1080p vs. reliability is.

Another idea would be to use a HDFury to convert to VGA, then feed into the ZeeVee, which states it supports 1080p output. We have used the HDFury-to-VGA before to use with TVs that did not have HDMI a couple years back. The concern there is that there was a shift to the left that had to be manually adjusted on the TV. I'd worry if the ZeeVee would handle this shift OK during the encoding...I'm trying to eliminate headaches, not add any.

I saw the DMS 3503B on Sencore's website (along with the DTA 115). This looks interesting, and shows a built-in BD drive (although this may be for illustration as the specs don't call it out). If I understand this correctly, this would do the same as the BT piece, but have the hard drive storage for media files and possibly BD playback (with internal BD drive). I'm waiting to hear back from Sencore.
