Abstract: The simultaneous use of multiple video and audio formats on a variety of physical interconnections, coupled with the demand for increased efficiency, has created challenges for today's systems engineers and planners when specifying a routing switcher. Transitioning to various high-definition video formats and increasingly dense audio formats has increased the overall complexity of these multiformat systems—a 36,864 × 36,864 embedded audio matrix for an 1152 × 1152 video router. Along with this transition, audio and video processing requirements should be accommodated. Internal processing enables system and operational efficiencies: Control is simplified, and a flexible input/ output arrangement allows easy reconfiguration between uses. This paper discusses the formats and media involved when routing simultaneous, multiple video and audio formats on a variety of physical interconnections and the implications of operating in such an environment. It proposes possible operational practices and reviews the practical solutions available. Finally, it offers a glimpse into the future—will the routing of simultaneous, multiple video and audio formats get easier?
