With the release of an approved SMPTE 2110 standard, the video sector of broadcast and production has additional guidance for further development. The audio portion of content generation and delivery has also some guidance, but less so. Certainly AES67 is key to AoIP delivery, but what about larger audio network issues?
Then there is the issue of moving to 4K/UHD. How does an engineer connect wide-band cameras and other gear together? The bandwidth demands of 4K signals currently require the use of four cables per 4K source. Such a solution is both expensive and weight intensive. Learn about alternatives in the accompanying article as writer Michael Grotticelli explains how production trucks resolve the issue.
Point to point connections with well-designed standards have given broadcaster engineers piece of mind for many years, knowing when they connect one AES-3 audio output to an AES-3 audio input, the two will connect seamlessly and audio will pass without incident. The same can be said of MADI and analogue twisted pair. Signal routing is easy to follow using numbered cabling and system diagrams.
The world of IP is very different. Trying to take the output of one device and connect it to the input of another is often fraught with problems. The only commonality is the definition of the Internet Protocol, defining the header and payload information for packetized data to be sent to different buildings over a variety of networks using routers and switches. Consultant Tony Orme provides practical advice in his article, “Understanding IP Networks - Why Do We Need Interoperability?”
Broadcast cable providers now offer a 12G-SDI 4K UHD Single-Channel BNC cable to help reduce weight and points of potential failure.
With the emergence of 4K and HDR production, remote production companies and studios have been struggling to make sense of the additional requirements for more cabling (4X more) and native equipment that supports it. Where the highest quality HD signal uses a single 3Gbps SDI cable to connect point A to point B—e.g., a camera to a production truck—the same workflow in 4K (or UHD) requires four separate 3 Gbps cables, often referred to as a “quad link” or “4-wire” infrastructure.
There is now a solution, which relies on single 12 Gbps SDI cable that is roughly 30% lighter than four 3 Gbps cables. This allows a remote production truck to carry less weight, eliminate dozens of cables and still produce beautiful 4K or UHD pictures. Want to know how it could benefit your operation?
