AptoVision’s award-winning BlueRiver NT+ Series is the world’s first family of chipsets designed from the ground up to efficiently and cost-effectively address all of the requirements of the professional AV market. The full-featured BlueRiver NT2000 includes Plethora Engine for in-line pixel processing. BlueRiver NT1000 is a scaled-down implementation designed for simple matrix switching and AV or KVM extension applications where complex video processing is not required. This lower cost chipset lets manufacturers offer a complete AV-over-IP product line at a variety of price points. It also enables the creation of endpoints (encoders and decoders) with much smaller footprints, making them ideal for installations where saving space is a priority.

Endpoints created using BlueRiver NT2000 and BlueRiver NT1000 chipsets, and controlled using software developed with BlueRiver API, are fully compatible. System designers have a broad toolkit they can use to create very efficient and cost-effective networks using only the functionality required at each node for deployments in education, healthcare, enterprise, entertainment, hospitality, retail, houses of worship, government, military, industry and security – wherever the need for uncompromised zero-latency 4K video arises.

Using a synchronous, packet-based architecture for pixel transmission, BlueRiver NT+ chipsets can extend and independently switch video, audio, gigabit Ethernet, and other control signals through off-the-shelf Ethernet switches. Replacing custom AV matrix switches with standard networking hardware cuts the cost and size of equipment by 60% while eliminating R&D costs, reducing time-to-market, and lowering inventory risk. BlueRiver NT+ chipsets are easily integrated into OEM designs for AV/KVM extension, AV/KVM switching, multi-view, and video-wall applications. Ready-to-manufacture reference designs are available for qualified customers.


BlueRiver NT+: One chipset, multiple applications

The ability to use off-the-shelf Ethernet switches for AV matrix switching has numerous benefits including:

  • Unprecedented cost savings: Ethernet switches cost up to 90% less per port than custom AV switches and this cost continues to decline. Moreover, manufacturers can save on R&D costs associated with developing multiple switch frame sizes, and instead focus on a portfolio of feature-rich endpoints.
  • Increased I/O flexibility: Ethernet ports are fully bi-directional so each port may be treated as an AV input or AV output. I/O Ports of custom AV switches are dedicated as either input or output, usually with an equal input to output ratio on the chassis. This commonly results in many unused ports.
  • Built-in scalability and future-proofing: High bandwidth up-links on Ethernet switches allow easy expansion beyond the capacity of the initially installed switch. Custom AV switches must be completely replaced when their I/O count is exceeded.
  • Unmatched I/O density: Ethernet switches deliver 48 ports or more per 1U of rack space. Custom AV switches consume four times as much space, and often more.
  • Shared Infrastructure: As a standard LAN backbone, other networking gear can be used on the 10G AV network eliminating the need to install and maintain independent AV and data networks. BlueRiver NT+ allows a full gigabit channel to be reserved for data traffic, ensuring no bottlenecks.
  • Widely available control software: Decades of pre-existing R&D for LAN monitoring and control can be leveraged for AV switching without the need to develop custom control software.
