NVISION 8500 Router IP Gateway

The NVISION 8500 Router IP Gateway provides broadcasters and media organizations the ability to future-proof their facilities for the transition from SDI to IP infrastructures. By packetizing real-time, uncompressed, baseband video using SMPTE ST 2022-6, the IP Gateway gives broadcasters and media organizations all they need to transport video over 10 GigE networks.

The IP Gateway consists of input/output cards that are installed into any NVISION 8500 HYBRID router frame. The input cards accept encapsulated, uncompressed video, such as SMPTE ST 2022-6 high bitrate, and decapsulate the video so it’s ready for use by the entire video matrix. The output card takes uncompressed video from the matrix and encapsulates it as SMPTE ST 2022-6 for transport of high bitrate media signals over IP.

Once SDI signals are packetized, they can be easily transported over IP to a long list of potential applications, including rack-to-rack, truck-to-truck, between floors of a facility or even between buildings on a campus. All signals support low latency and frame accurate switching for use in live production.

The IP Gateway cards can be added to any NVISION 8500 HYBRID routers, including those already deployed in users’ facilities.

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 provides 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.

Integrated Audio Processing

The NVISION 8500 HYBRID Router Series Disembed/Embed Output Card 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 reduc-ing latency introduced into the program. This functional integration saves costs, as well as space, weight and power. It also streamlines the workflow and minimizes 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 flexi-bility for your hybrid router.

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.

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 reduced 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.

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 unparal-leled 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.

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:
