NVISION 8500 Enterprise Class Routers Strengthened

Miranda Technologies has strengthened its NVISION 8500 Enterprise Class 3Gbps/HD/SD routers with new integral de-embedding, shuffling and re-embedding capabilities.
Using new 'hybrid switching technology', every frame in the family can now de-embed, route and re-embed up to 16 channels of mono audio per video input, and output in a completely non-blocking audio/video switch.
This is achieved without affecting the router's crosspoint redundancy, superior cable management and exceptional cooling design.
The ultra-resilient NVISION 8500 routers with embedded audio shuffling are especially suitable for use in production trucks, where space and cable management are critical. Integrating de-embedding, embedding and mono audio channel shuffling within a router eliminates numerous outboard cards, card frames, and inter-frame cabling, while also reducing power consumption.
Tim Walker, Router Product Manager at Miranda, said: "Router delay is a critical factor for audio and video. Large production switchers need video router path delays to be very short, much less than half a line, particularly when signals re-enter the router. And audio delay must be very short, and predictable, so that the multi-channel audio image is preserved.
"Our de-embedding and embedding audio process uses advanced algorithms to keep video delay at less than half a line, and hold the delay of audio constant at one video line."
Using two 32RU frames, the NVISION 8500 can provide up to 1024 video inputs and outputs, each with 16 mono audio channels providing a combined 1024 suare and 16,384 square video/audio router.
The hybrid embed/de-embed cards can be mixed and matched with standard video cards, creating a nearly infinite number of configurations. The hybrid cards can be installed in any 8500 family frame, from 144x144 to 1152x1152.
The NVISION 9000 Control System provides advanced control of audio/video levels and breakaway, including mono audio. Using the NVISION 9000's advanced path finding allows users to optimise the use of hybrid I/O modules, including breakaway. In most cases, only a portion of the router requires hybrid capability to deliver the required audio performance, and this minimises the cost.
The NVISION 9000 Router Control system offers a wide variety of highly flexible hardware and software control panels. This highly configurable control system provides sophisticated multi-hop, tie line management and SMNP support. It also offers cost-effective bridging with legacy third party router systems to allow an easy transition to a Miranda NVISION system.
