Multiformat Operation - System Implications and Solutions for Routing Switchers

This paper discusses the formats and media involved when routing simultaneous, multiple video and audio formats, on a variety of physical interconnections, the implications of operating in such an environment, proposes possible operational practices, and reviews practical solutions available. The simultaneous use of multiple video and audio formats, on a variety of physical interconnections, coupled with the demand for increased efficiency, has created new 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 multi-format systems—a 36,864 × 36,864 embedded audio matrix for an 1152 × 1152 video router! Simultaneously, audio and video processing requirements should be accommodated. Internal processing enables system and operational efficiencies: Control is simplified; a flexible input/output arrangement allows easy reconfiguration between uses. Finally, a glimpse into the future - will it get easier?
