The broadcast industry is undergoing a dramatic transformation, with a growing emphasis on software-based solutions. This evolution is particularly evident in the realm of production switchers, critical tools for live video mixing and effects. Traditionally, hardware switchers have dominated broadcast control rooms, but the emergence of software-based alternatives promises greater flexibility and scalability. This shift has been accelerated by the rise of IP-based workflows and remote production, making software switchers an increasingly attractive option for certain applications.
While software solutions offer a plethora of advantages, hardware switchers still retain their value, especially for large-scale, high-stakes productions that prioritize reliability and low latency. The choice between software and hardware ultimately depends on specific production needs, and it’s crucial to carefully weigh the benefits and drawbacks of each approach.
“Because technology is rapidly changing, the essential difference is that hardware solutions lock you in with the capabilities of today, while software-based solutions provide you with much easier deployment when new advancements are made,” explained Ryan Hansberger, head of product development for video mixing at Vizrt. This inherent flexibility of software extends to remote productions, with Hansberger emphasizing that software solutions empower productions to “happen essentially anywhere, while maintaining reliability and performance.”
“With the software-based switchers, extension of functionalities is possible at any time without changing specific hardware and is always therefore future-proof,” said Greg Huttie, VP of production switchers at Grass Valley, highlighting the upgradeability advantages of software solutions. But despite these advantages, hardware switchers retain their dominance in certain performance metrics.
“While these software-based offerings can complement a hardware-based production switcher for producing alternative feeds or sub-shows, they still lack the horsepower of today’s purpose-built production switchers,” said Deon LeCointe, director of networked solutions at Sony Electronics. This sentiment is echoed by Satoshi Kanemura, president of For-A, who highlights the low latency and robust security of hardware switchers.
“A hardware switcher’s latency for processing and operation is minimal, and there are no potential network security issues,” stated Kanemura. However, Huttie believes that the gap in performance between software and hardware is steadily narrowing.
“Both software-based and hardware-based production switchers can be optimized for reliability and performance across various applications. Key features such as redundant IP networks, handling multiple formats, and power supplies can enhance the reliability and performance of both types of switchers,” Huttie noted. The ability to support remote production workflows has gained significant importance in the current broadcast landscape, and software-based switchers often excel in this domain.
“Software-based solutions also provide greater flexibility for remote productions, enabling them to happen essentially anywhere, while maintaining reliability and performance,” affirmed Hansberger. LeCointe emphasized the role of advanced IP technologies in facilitating remote workflows.
“The advent of advanced Media over IP technologies including SMPTE ST 2110, SRT, and NDI have ushered in a new age of connectivity for production switchers which has enabled new remote workflows,” said LeCointe. Keith Vidger, principal technical consultant at Panasonic Connect, highlighted the remote control capabilities of modern on-premise switchers.
“Operation of an on-prem switcher can happen remotely as well, if the switcher supports streaming of its multi-viewer outputs and can connect control panels to the switcher via the internet,” said Vidger. Manufacturers are strategically adapting to the changing technological landscape, with hardware switchers often adopting modular designs to ensure future-proof adaptability.
“The overall modular structure of the hardware-based K-Frame’s I/O and processing boards affords either introduction of new boards or adding functionality (some examples: introducing onboard JPEG XS signals processing, color mapping of HDR and SDR, and adding additional clean-feeds),” explained Huttie, outlining Grass Valley’s modular approach. Software-based solutions, by their nature, offer a more straightforward path to upgrades.
“We’re implementing software-based architecture that easily supports any future requirements, all formats, and all compression standards,” stated Kanemura, reflecting For-A’s commitment to future-proof software solutions. The increasing adoption of cloud-based production environments is also influencing switcher development.
“We have already seen the introduction of software-based production switcher platforms, like Sony’s M2L-X, which can be deployed on premises in COTS hardware and on the Cloud,” said LeCointe on Sony’s approach. Huttie further emphasized the flexibility of Grass Valley’s software-based switchers.
“The location of the processing does not limit the functionality or performance of the production switcher and can therefore be freely selected as required,” Huttie noted. In the end, the choice between software and hardware production switchers comes down to the specific production needs.
“The choice between software and hardware solutions often depends on specific production needs rather than inherent limitations in reliability or performance,” said Huttie. Factors to consider include the scale of production, required features, budget, and the importance of remote operation capabilities.
As technology continues to advance at a rapid pace, the distinction between software and hardware switchers may become increasingly blurred.
“It is just a matter of time until we see software-based solutions that provide the same specs as their hardware-based predecessors,” predicted LeCointe. For broadcasters navigating the evolving broadcast landscape, the decision between software and hardware switchers requires a careful consideration of flexibility, performance, and future scalability against current production requirements.
