Traditionally, production and broadcast facilities have used dedicated digital video and audio routers plus external de-embedders/embedders for signal management. This equipment has provided the ability to overcome typical signal problems like audio channel mismatching. However, this approach has now been superseded by the NVISION 8500 Hybrid router, which integrates digital video/audio routing and 16 channel de-embedding/shuffling/embedding and break-away. This functional integration saves costs, as well as space, weight and power (see table page 354). It also eliminates audio to video latency problems due to external de-embedders/embedders, while also streamlining the workflow, and minimizing cabling.
The NVISION 8500 Hybrid router performs audio processing using Hybrid input, crosspoint and output modules, which fit inside a single frame alongside regular (non-audio processing) modules. By using Dynamic Hybrid Pathfinding, the router can perform audio processing across all its video inputs, with just a small portion of its matrix equipped with input, crosspoint and output cards capable of audio processing.
The Dynamic Hybrid Pathfinding process automatically routes signals via the audio processing modules whenever required, under manual or automated control. This architecture promotes optimal cost-efficiency by reducing the requirement for more expensive Hybrid modules, without impacting overall functionality.
