The BrightEye NXT 450 Compact Router from Ensemble Designs adds a high quality, high profile H.264 (MPEG-4) encoder to the BrightEye NXT family of compact routers. The Encoder produces both a high and low resolution output simultaneously. Any SDI input can be fed to the encoder through the built-in format converting Clean Switch, allowing seamless switching or mixing between all inputs. The independent decoder operates simultaneously, with baseband output in any desired format. The decoder output can be switched along with any other source to any destination. An NXT 450 can serve as a full duplex codec, supporting both an outgoing and incoming streaming path. Encoding and decoding are fully integrated with the full set of resources in the NXT 450.

Encoded streams can be sent or received through IP networking or by direct DVB-ASI connections. The NXT 450 incorporates an RJ-45 Gigabit Ethernet port dedicated to streaming connectivity. The encoder output can be delivered by either unicast or multicast addressing modes over the IP connection. Two unicast outputs can be independently directed to any desired destination. The multicast output is limited to the immediate subnet that the NXT 450 is connected to, but can be received by multiple devices. In addition to IP outputs, a DVB-ASI formatted stream can be output through a BNC port, or by fiber with an SFP module. For each of these outputs, IP or ASI, there is independent selection of the high or low resolution stream. The NXT 450 can receive an IP stream from the media port, or ASI from any BNC or fiber input. This stream will be decoded to produce a baseband SDI signal with embedded audio.

Flexible Architecture
Flexible I/O configuration allows on-the-fly changes to the number of inputs and router destinations. From 9 inputs and 2 outputs, to 2 inputs and 9 outputs, the NXT 450 adapts to different needs. The two SFP ports allow for fiber optic connections, HDMI I/O, or additional HD-BNC SDI connections. You can genlock the Clean Switches and TSGs using the external reference input or assign a Clean Switch to an output. The encoder is driven as a destination of the routing matrix, and the output of the decoder is a source to the matrix. You can feed any source to the encoder, and feed the decoder to any destination.
Instantaneous Clean Switching and Format Conversion
The NXT 450 contains two Clean Switches. When assigned to an output, they provide clean, quiet switching, even between asynchronous sources. The format conversion feature provides automatic conversion of inputs to the chosen output format. This makes it possible to cut and mix between different input formats. Frame synchronization in the Clean Switch is particularly valuable when assigned to the input of the encoder. It guarantees that the encoder receives continuous, uninterrupted synchronization, regardless of the timing or condition of the input signals.
Multiple Control Options
Control and configuration of the NXT 450 can be made from a variety of interfaces. The front panel provides a full motion, real time video display of sources and destinations. You can route signals and configure resources directly from the front panel or connect the RJ-45 control network port to a LAN, for control using the built-in web server. From smartphone, tablet, or laptop, you can view thumbnails of all the sources and destinations, make routing changes, and configure parameters of all the NXT 450 resources. Control from third-party devices can be accomplished by TCP/IP or RS-232 protocols. Or you can use the 5835 Control Panel to provide a fully customizable operator interface.
