Sinclair Broadcast Group continues to lead the industry’s transition to the future of television, developing innovative solutions to meet its requirements for channel playout and live broadcasting.
These include a new 25,000-square-foot, SMPTE ST 2110 media operations center for Sinclair’s regional sports networks (RSNs) with cloud-hosted disaster recovery channels, and a large-scale ST 2110 production facility for its Tennis Channel featuring a cloud-based environment for pop-up live special events.
All were built around Imagine Communications infrastructure and playout platforms.
Don Roberts, VP of sports engineering and production systems at Sinclair Broadcast Group, makes the point that both business and technical requirements are driving Sinclair’s transition to IP connectivity and software-defined architectures ― and particularly cloud deployment. “This transition cannot be a simple lift and shift of legacy systems; it is the opportunity to take a fresh look at the way a broadcaster operates,” Roberts said. “We have to start from good user engagement, to understand what will change at each step. The transition to IP and the cloud is transformative. We can’t just flip a switch ― we have to redefine how the business works. This is change management as much as technology.”
A powerful advocate of the SMPTE ST 2110 family of standards, Sinclair has a long history in collaborating with Imagine Communications to develop IP playout and production systems. Following its 2019 acquisition of regional sports networks from Fox/Disney, Sinclair had to quickly develop a new playout strategy and decided to build an IP-based facility from the ground up to serve as a future-proof hub for the new RSNs.
“Armed with our experience with IP and our strong technical relationship with Imagine, we decided that our first step was to develop an on-premises solution for the RSNs,” Roberts said. “We also developed options to put some functionality ― like the archive and disaster recovery playout ― into the cloud. This enables us to use the Atlanta facility as a stepping-stone, continually refining the workflows and business cases that will help us transition to a hybrid approach that balances capability and cost.”
At the same time, Sinclair was developing a platform for its Tennis Channel, a service that features comprehensive coverage of the top 100 tournaments in the sport and more. The channel has a master control center in Santa Monica, Calif., which uses the flexible Versio platform, both on-premises for primary origination with Imagine’s ADC automation, and as software instances hosted in the AWS cloud for pop-up special events under the control of the cloud-optimized Version Automation system. IP connectivity allows simplification of the hardware architecture, for instance, through use of the virtual re-entry software features of Imagine’s Magellan SDNO to create virtual patch panels, router paths and workflows.
The Tennis Channel project presented Sinclair with a new set of technical, operational, and business challenges. “Tennis is live and unpredictable, so we need our playout capabilities to be agile and responsive,” Roberts explained. “Software solutions like Versio give us that agility ― the ability to make a decision and have it on air virtually instantly. And because it can be hosted in the cloud, we simply spin it up at the beginning of each tournament and close the software when it ends.”
Central to the architecture at the Santa Monica center is Imagine’s Selenio Network Processor, which Roberts defines as “a broadcast Swiss Army Knife ― if you have a problem with a signal, throw an SNP at it.” Each 1RU SNP device hosts four independent, software-defined processing channels. At the Tennis Channel facility, the SNPs act as IP gateways and support format conversion, which allows the facility to be primarily 1080p, but accommodate 4K and HDR UHD when needed, such as for the French Open Tennis from Roland Garros in Paris. The facility also uses the new SNP-MV multiviewer personality, allowing for tactical multiview displays to be quickly established wherever they are needed in the workflow.
The new Tennis Channel ST 2110 infrastructure debuted in December 2020. Sinclair then went live to and from the cloud during coverage of the 2021 Miami Open in March, marking the first time that any broadcaster had supported such a high-profile live sporting event via live cloud playout. The innovative combination of cloud playout and on-the-ground master control provided a solution that was particularly powerful in a time of COVID, which has challenged media companies to continue producing quality broadcasts, while ensuring a safe work environment for operational staff. The unique capabilities and integration of Imagine’s IP-enabled playout and core infrastructure products created a cutting-edge architecture and workflow that helped make this possible.
