IP and the 80 Percent Rule

WCCB Logo“Our philosophy is to operationally stay within the system box…doing 80% that works consistently and reliably on a daily basis rather than 100% that doesn’t.”

Those are the words of Bob Davis, Director of Engineering and Operations for regional broadcaster Bahakel Communications headquartered in Charlotte, NC, and they make good sense to any broadcaster who wants to move into IP workflows without making a mess of things.

As he explains, “Providing a solid and stable system design for our production and operations teams while keeping them within well-defined parameters is the key to our success in the world of IP video and audio.”

Bahakel has been perfecting the 80 percent mindset for two years, during which time the group has linked up three of its six stations over IP for live, daily production. From its WCCB-TV studio in Charlotte, the group produces WOLO-TV’s newscasts from nearby Columbia, South Carolina. All studio cameras, mics, IFB, prompter, weather system, and set monitors in the downtown Columbia newsroom are linked to Charlotte by IP. In Charlotte, it all goes through production and master control, and is then re-encoded with all the sub-channels and sent back to Columbia via IP transport for transmission.

The same setup is used for some programming for WFXB-TV in Myrtle Beach. Mid-day weather is presented from the Columbia newsroom, through WCCB-TV production, and fed back via IP to WFXB-TV for air. News and weather content can be originated from any of the three locations for all three stations, as was the case during Hurricane Matthew.

Wheatstone’s Dimension Three IP audio console handles the mixing, mic control and IFB for all three from the Charlotte studio, using WheatNet-IP audio network I/O BLADEs. The three studios are less than a few hundred miles from each other. For audio-video transport, Bahakel uses Adtec, Harmonic and Sencore equipment for the IP links. “Often syncing the audio and video is a problem, but for us it has not been. We make sure the A/V encoding is done properly, with close attention paid to stream parameters and system design for synchronization so there’s no video and audio drift,” explains Davis.

Read the rest of the story:  

There is a slight delay due to H.264 HD 4:2:2 quality video encoding and transport, but Davis says this has been an anticipated part of production since the group began central-casting WOLO-TV from WCCB-TV over earlier DS3 circuits years ago.

The difference is that by going from DS3 circuits to a dedicated IP link, the group has cut transport costs in half – and without compromising reliability. When Hurricane Matthew came through the area last fall, Bahakel broadcast live on all three stations from all three stations, continuing to broadcast even during a mass evacuation in Myrtle Beach without losing IP connectivity. WFXB-TV’s building was empty and dark, remotely operated from WCCB-TV during the storm.

“Everything we do is around the idea that it has to work reliably without daily intervention, and we prove the system beforehand so we know the operational limitations,” explains Davis. As IT technology proves itself over time, the group then folds those new developments into its operation, making the best of current technology without getting stuck with early adopter reliability issues. WCCB-TV started with a Wheatstone TV80 analog audio console in 1999, and then upgraded to the Dimension Three with touchscreen access in October of 2016. “We evaluated the console and saw that it could be connected via (IP audio network) BLADEs, and thought, ‘let’s see what else we can do with that,’” says Davis. “Wheatstone’s service and support are superb, so we had confidence their IP products would meet our needs.”

Recently, he expanded on the WheatNet-IP audio network with Wheatstone’s EDGE and AuraIP-8 BLADE for an eight-channel audio link over Ethernet IP. The group uses the system for transporting multiple Columbia radio stations’ audio back to WOLO-TV’s master control in Charlotte for Emergency Alert System (EAS) compliance.

“While we do push the envelope here, rather than going for the 100 percent that’s problematic, we go for the 80 percent that works. That’s working very well for us,” sums up Davis.

Sounds like a good plan to us.

IP Audio and At-Home Remote Productions

PhilChart3Audio has been comfortably traveling on IP for years and we’ve now arrived at a point where the IP audio model has become extremely useful for at-home remote productions.

Systems that were previously put together with an assortment of signal types (analog mic and line, AES, GPI, SDI) can now be assembled using IP as the unifying signal type.  This is particularly helpful for creating a “network on location” that can handle audio I/O, IFB, and audio processing.

This approach involves the use of IP audio I/O endpoints at the home studio and at the remote location, where there’s a variety of signal types for ingesting wireless and wired mic sources, and IFB to various talent and camera-persons, plus program outputs.

IP audio endpoints help create a unified signal matrix for routing any audio or control input to any output over an integrated network of devices all running on Gigabit Ethernet. In addition, with the advent of intelligent endpoints, aggregating baseband audio signals into mixed and processed IP audio streams is now possible. For example, our WheatNet-IP endpoints, or I/O units known as BLADEs, have built-in mixing and processing so that venue-side levels can be controlled from the main studio. Similarly, if an ambient crowd mic at the venue location has too much low end, the producer at the main studio can apply a high pass filter remotely.

Wheatstone’s Phil Owens and Lon Neumann will be discussing these and other details of At-Home Remote Production with IP Audio Networking at the upcoming NAB2017 BEIT conference, Saturday, April 22, Room N256.  We hope to see you there.

Your IP Question Answered

EQ

Q: How does your WheatNet-IP audio network handle IFB? 

A: If you have an existing IFB intercom system, you can interface it directly into the WheatNet-IP audio network using our MADI unit. Or, you can use the WheatNet-IP audio network as your IFB backbone. We have utility mixers built into the system’s I/O units, known as BLADEs, so you can  create mix-minus anywhere in the network. Either way, IFB can be preset, controlled and triggered from any IP console in the WheatNet-IP audio network.
