Broadcast positioned to catch up with consumer tech, finally
Video over Ethernet is coming to production facilities and I’m excited. For years I’ve been telling anyone who’d listen that the broadcast production/distribution model needs to become more flexible if it is going to keep pace with changes underway in consumer electronics. A consumer can already buy reasonably priced equipment that exceeds the best quality and experience any traditional media company currently provides to homes.
For example, we are seeing UHDTV gain traction. Its support for high dynamic range has an impact on the viewing experience that consumers can readily appreciate (see http://www.positiveflux.com/flux-reports-uhdtv/).
The catch is that UHDTV requires four times the bandwidth of HDTV. Signals being sent around production facilities will not work with previous generations of equipment. That’s where Video over IP comes in.
The higher bandwidth could of course be met by improvements in SDI over coaxial cable and BNC connectors. These are highly standardized and “plug and play,” however. It currently takes four 3Gbps HDSDI cables to connect a single UHDTV signal between devices. Devices with 6Gbps interfaces are starting to ship and standards have been adopted for 12Gbps SDI and higher. The problem is that speed increases for SDI historically have been linear.
