4K UHD HDMI monitoring

Epoch | 4K Neutron. 4K UHD HDMI Monitoring.

4K Neutron includes a cost-effective HDMI monitoring solution supporting up to 4K UHD resolutions. Enjoy simultaneous 4K UHD HDMI & UHD SDI from 4K Neutron.


Low-latency video keyer

Epoch | 4K Neutron. Low Latency Video Keyer.

4K Neutron has a low-latency hardware video keyer allowing video layers to be combined in hardware with microseconds of delay. This feature allows animated logos, captions, tickers, etc. to be keyed over live video feeds at full 12-bit precision and with minimum input to output delay. The hardware keyer can also function as an image pre-multiplier to assist in previewing images with alpha data.


DMA features

Epoch | 4K Neutron. DMA Features

The industry's lowest-latency I/O, by design

4K Neutron has, by design, the world's lowest-latency providing access to captured fields or frames to on-board card memory even before the whole field or frame is complete, thereby reducing the latency to sub one field or frame. During a capture or playout, each process can occur at less than or equal to 1 field for interlaced modes, and less than 1 frame for progressive modes.


Low-latency framestores

4K Neutron firmware and driver architecture provides I/O framestores with predictable and short propagation delays enabling the lowest possible latency through the card. The Bluefish444 SDK supports sub-field interrupts enabling access to the video field or frame even before the video field/frame has been fully captured. This low-level access to video and audio data provides maximum control over video and audio synchronisation.

FIFO mode protection

4K Neutron firmware and driver architecture supports a FIFO mode that can be utilised for buffering I/O framestores ensuring that no field/frame will ever be dropped. The FIFO architecture can be used to increase or decrease the I/O latency to a fixed value.


Full-duplex asynchronous DMA engine

4K Neutron developers have full control over the heavily optimised DMA engine via the Bluefish444 SDK. The DMA engine supports full-duplex transfers to and from each of 4K Neutron’s 4 video channels at the maximum available PCIe bandwidth.

The DMA engine can independently transfer video and anciliary data and has a selective DMA feature for the transfer of customisable portions of a video field or frame. This is especially useful when dealing with individual HD quadrants that make up a 4K video buffer.


Complete access to ancillary data

Epoch | 4K Neutron. Complete access to ANCILLARY Data

4K Neutron allows full read and write access to the VBI for standard definition video signals. In high definition signals, read and write access is available for HANC and VANC data allowing AFD, KLV, closed caption data and more.


The industry’s lowest jitter, by design

Epoch | 4K Neutron. The Industry’s lowest jitter, by design.

Building on 10+ years of Bluefish444 innovative hardware development, 4K Neutron jitter circuit design surpasses the industry’s minimum standard for jitter and eye pattern measurements by almost twice the permitted tolerance.


High quality 3G/HD bypass relays

Epoch | 4K Neutron. High quality 3G/HD bypass relays.

4K Neutron offers the highest quality 3G/HD/SD bypass relays allowing critical on-air systems to manage system failures, power outages, and other unforeseeable circumstances that can be encountered in the world of live broadcast systems.


MR2 Master Routing Resource

Epoch | 4K Neutron. MR2 master routing resource.

The MR2, Master Routing Resource, within 4K Neutron enables a user to flexibly configure main and preview outputs to suit individual workflows. The Master Routing Resource acts like a telephone exchange for super connectivity. Allowing video from SDI or host workstation to be routed to any or all of the 4K Neutron outputs simultaneously.


Maintaining a 12-bit processing pipeline

Epoch | 4K Neutron. Maintaining a 12-bit processing pipeline

A 12-bit image processing pipeline is standard within 4K Neutron. This allows 8, 10 & 12-bit SDI video signals to be produced from 8, 10, 12 & 16-bit pixel formats providing the highest image quality available from your source material. A 12-bit image pipe means that 4096 discrete values of red, green & blue are maintained per-pixel; that’s 4 times the colour precision of a traditional 10-bit processing pipeline!


Maintaining the highest quality RGB <=> YUV

Epoch | 4K Neutron. Maintaining the highest quality RGB <=> YUV.

Colour space conversion image processing includes a fully programmable 4 x 4 x 33-bit colour matrix providing the highest quality colour space conversions that are a standard requirement in professional video workflows. The fully programmable 4 x 4 x 33-bit colour matrix reduces colour space conversion errors and ensures the highest quality colour accuracy during capture, monitoring and mastering.


Primary hardware colour corrector

Epoch | 4K Neutron. Primary Hardware Colour Corrector

When the 4K Neutron programmable matrix is combined with the onboard 1D LUTs, it provides a powerful primary hardware colour corrector. 4 x 1D x 12-bit LUTs on all SDI outputs gives maximum control over lift, gamma and gain prior to monitoring or mastering your precious video assets.



Epoch | 4K Neutron. SDI <=> ASI.

4K Neutron can capture, play-through and playout raw transport DVB ASI streams in addition to supporting SDI I/O. 4K Neutron offers the flexibility to choose between capturing 4K/2K/HD/SD SDI or ASI and similarly the flexibility to choose to playback either 4K/2K/HD/SD SDI or ASI. That’s maximum transport flexibility for either live or file-based workflows.


Achieve advanced 4K workflows
