These are driven a lot by the consumer TV industry and broadcast standards changing. Two major changes are going from standard definition to 4K/UHD and VGA/DVI becoming less popular and DisplayPort growing in popularity for computer graphics. How has processor technology changed over the years you’ve worked at Daktronics?ĭemand for a larger canvas size has skyrocketed. It makes you realize how cool the technology is that you’re working on, which is easy to forget when you’re immersed in it every day. Typically they have either electrical or computer engineering backgrounds and they haven’t worked on anything like a Daktronics processor before because the design is so custom. Students are shared resource throughout engineering so they work on a lot more than just video processing projects, but they’re typically super excited to work on video processing projects when they’re tasked with them. How is working with students different than the day to day work with your colleagues? ![]() We all have to work together to make a successful final product, so we’re a tight-knit group. Four people may be working on a logic card that’s 2 inches x 2 inches, so it’s a tiny size, but a lot of technology is packed into a small device. You have people dedicated to signal type compatibility, image refinement features, writing the code that controls all those features. ![]() Video processors are so complex, no one person can be an expert in all aspects of the product. When there’s a development, we’re all working together to build one box. What I like the most about working on the processor team is that we’re all in it together. ![]() What’s your favorite part of working on the processor team? It also refines video visual quality by precise scaling, gamma correction and evening out color quality between camera sources. The processor also makes the show look more dynamic by providing transitions and wipes between different content segments. ![]() You can use one layer on your processor for a heart graphic and you overlay that on top of your camera man’s feed and it would show the graphic over the live feed of the couples in the crowd. Processors can also bring an interactive experience to the fans. Camera operators are positioned all around the field or court, and the video processor brings all these multiple videos from different vantage points together into a single, formatted viewing experience. The video processors are an core part of making sure live video feeds look good on the display. What part does video processing technology play in the fan entertainment experience? We recently sat down with Megan Wiskur, 10-year engineer team member, to talk about how video processing enhances the fan experience and what it’s like developing this technology at Daktronics. As part of National Engineering Week, we’re highlighting a few members of our engineering staff whose minds power the display and control technology showcased all over the world. ![]()
