Frame Sync Functionality

The NVISION 8500 HYBRID Router Series Frame Sync Input Card has eight input ports and enables the simple synchronization of incoming wild feeds or signals moving between facilities. Previously, in applications that required the processing of eight feeds, eight frame synchronizers using eight processing cards were required. This new input card eight frame synchronizers on a single card — with 3G, HD and SD all supported on the same module. The Frame Sync card supports multiple frame rates and formats and can shuffle audio at the input.

Key Features
  • 8 input ports, each with 4 frame buffer
  • Manages 16 channels of embedded audio per port
  • Audio is disembedded to TDM matrix for total flexibility
  • Dolby E aware
  • Synchronizes 4K quad-link signals

Integrated Audio Processing

The NVISION 8500 HYBRID Router Series Disembed/Embed Output Card that conveniently embeds audio into any embedded audio channel location, even when managing inputs from non-hybrid sources. The addition of this functionality within the NVISION HYBRID Routing platform enables unprecedented flexibility with embedded audio while also greatly reducing latency introduced into the program. This functional integration saves costs, as well as space, weight and power. It also streamlines the workflow  and minimizing cabling.

The DEM/EMB card can embed audio into any embedded audio channel location without disrupting the original audio channels and can break into existing embedded audio on a channel-by-channel basis.

This DEM/EMB card will also allow you to shuffle embedded audio that comes from a standard video source which gives you the ultimate in flexibility of your hybrid router.

Key Features
  • On-board 18x1 shuffling of original embedded audio
  • Easily shuffle audio from any standard or embedded source to any channel output
  • Consistent, predictable low audio latency levels
  • Preserves and duplicates standard audio

AA/AES/MADI Audio Concentrators

To further streamline cabling, the NVISION 8500 HYBRID routers can be used with NVISION 8900 audio concentrators. These devices convert Analog or AES to MADI, and MADI to Analog or AES, and this can radically reduce the number of audio cables needed in broadcast infrastructures. This reduces installation costs, simplifies troubleshooting, and reduces weight in a mobile environment.

Typical Audio Processing Applications

Feeding audio console with signals from production switcher
The NVISION 8500 HYBRID router is ideally suited for connecting a production switcher and audio console in a control room. The router’s integrated audio processing eliminates the need for external de-embedders/embedders for feeding MADI to/from the audio console, and this eliminates audio to video latency problems.

Swapping audio between MADI and embedded sources
MADI audio tracks, such as a voice-over from an audio console, can be easily embedded into SDI video.

Switching embedded audio between two signals
The integrated de-embedding, shuffling, and embedding simplifies the task of switching audio tracks between embedded video signals.

Swapping embedded audio tracks
Integrated audio processing simplifies the task of embedded audio track shuffling, and this is performed using traditional router commands.

Streamlined Cabling Using Coax and Fiber

The NVISION 8500 HYBRID routers offer highly streamlined cabling using either coax or fiber. The unique, clean design of the router provides unparalleled signal integrity and allows longer coax cable runs, using high density cable connectors which save space and lower weight. Advanced direct fiber connectivity is also available, using SFP modules for 1310 nm or CDWM wavelengths.

The use of high density cable connectors on large routers provides densities two to three times that of conventional BNCs, and lets you fully exploit cost-effective coax cable for shorter runs, along with major rack-space savings. The smaller DIN 1.0/2.3 connectors are less stressed than traditional BNCs, and they don’t require a tight bend radius, this contributes to a better RF launch profile, and a better return loss.

Direct fiber connectivity is available using removable fiber SFP modules (single mode, Dual LC connectors at 1310 nm), which simplify configuration and maintenance. For more advanced fiber requirements using CWDM, there is a rack mounting tray that holds 4 CWDM muxes/demuxes. With this configuration, 72 3G/HD/SD signals are transmitted by four fibers.

Ultimate Resilience with Redundant Crosspoints

The NVISION 8500 HYBRID router offers patented N-on-1 crosspoint redundancy to provide a zero downtime capability, with a back-up system for the largest possible impact block in the router. A redundant crosspoint array continuously shadows the main array and, in the event of a failure, a single action repairs the situation by “gang switching” all outputs to the good, redundant crosspoint card during the next vertical interval. Router maintenance can then be performed without impacting the facility’s operations. This maintenance process is outlined below:

  1. Normal operations: During normal operations, a redundant crosspoint array continuously shadows the main crosspoint array.
  2. Crosspoint array failure: A single crosspoint faiIure develops in the main crosspoint array.
  3. Switching to redundant array: A single action instantly repairs the situation by “gang switching” all outputs to the good, redundant crosspoint card during the next vertical interval.
  4. Returning to normal operations: Router maintenance can then be performed to repair the faulty array, without impacting the facility’s operations.
