opgenorthThe good news is that the 3g-SDI chip BM uses in the 4k ATEM (probably a Semtech GS2972, or GS3490) can do both levels A & B, so it'd be a firmware only fix for them to implement this.
This sounds promising as does the info which was posted on this forum by someone at BMD who talked about how their devices used to be level A only and then they switched to level B.
Well don't think so.. 2 simple reasons..
1 - 3G sdi chips in a 4K atem which is 6G sdi?? Sorry but that doesn't match...

2 - BMD uses mostly Macom chips instead of Semtech..
MACOM’s 12G-SDI enables Blackmagic Design to deliver 4K60P on a single link
Lowell, Mass., April 7, 2014 - M/A-COM Technology Solutions Inc. (“MACOM”), a leading supplier of semiconductor solutions for broadcast video infrastructure, today announced that Blackmagic Design, a leading manufacturer of broadcast and post production equipment, has selected MACOM 12G-SDI devices for their new 4K UHDTV conversion product.
12G-SDI is the next data rate in the evolution of the SDI standard. It is required in order to support 4K resolutions at 60 frames per second over a single coaxial cable, or optical fiber.
“Consumers appetite for 4K D-Cinema and UHDTV-1 content is growing at a tremendous rate. By using MACOM’s 12G-SDI products we are able to demonstrate 4K60P solutions carried over a single link to serve this new demand. The performance and robustness of the MACOM solution enabled us to be first-to-market with this exciting product, using the 12G-SDI interface,” said Grant Petty, CEO of Blackmagic Design.
“Blackmagic Design has a history of bringing innovative products to market and we are excited to be working with them,” said Hasnain Bajwa Senior Vice President and General Manager, High Performance Analog, at MACOM. “We continue to make research and development investments to enable the broadcast video industry to seamlessly transition to next generation standards.”
MACOM’s family of 12G products will be shown at the 2014 NAB Show on booth #N2819 in the North Hall of the Las Vegas convention center from April 7-10.
