The AVPRO Edge AC-MXNET-1G-DV2 represents the next step in the evolution of the MXNet AV over IP video distribution ecosystem from AVPro Edge. AC-MXNET-1G-DV2, an Evolution II decoding/receiving device, incorporates a newly designed AVPro Edge application-specific integrated circuit (ASIC) that introduces an improved software-based video encoding/decoding engine into the IC for enhanced video processing. Refinements to the IC include native support for 4K/60fps 4:4:4 signals (RGB and YCbCr @10- and 12-bit), plus extended audio capabilities to support high bitrate multi-channel formats, including Dolby Atmos and DTS:X for IMAX Enhanced soundtracks.
As a member of the AVPro Edge family of AV over IP products, an AC-MXNET-1G-DV2 is the destination endpoint within the MXNet Ecosystem where the signal arrives. At the input side, connected by either category wiring (Cat 5e is recommended) or fiber optic cabling to an MXNet switch or any compatible multicast-capable managed L3 network switch, an AC-MXNET-1G-DV2 receives multicast packeted data from an AC-MXNET-1G-EV2 encoder. This data, encoded using an optimized MJPEG codec, is precisely decoded per its encode rate (200Mbps for 1080p content, 300Mbps for 4K/30fps content, peaking at 850Mbps for 4K/60fps content). Control signals are unpacked and routed, per their intended application.
The new IC developed for Evolution II devices enables the AC-MXNET-1G-DV2 to excel at smoothly decoding 4K/60fps 4:4:4 signals, RGB or YCBCR 10- or 12-bit, with crisp, artifact-free detail and the added punch of dynamic metadata.
JPEG 2000
JPEG 2000 encoding implemented by MXnet differs from MPEG and other discrete cosine transform-based codecs, as it optimizes compression efficiency for applications with limited bandwidth. JPEG 2000 is based on a wavelet transform algorithm, providing lossless or lossy compression and parseable code streams. Genlock is supported, syncing a video source by frame to Decoders comprising a video wall, for a simul-sync, tear-free appearance. JPEG 2000 is reliably used by Digital Cinema Initiatives for theatrical content, by television networks for HD broadcasting, and by DICOMr for critical decision-making medical imaging applications.
Native 4K/60fps Support
First-generation MXnet Encoders and Decoders were unable to support 4K/60fps 4:4:4 RGB / YCbCr, 10- and 12-bit natively or with dynamic metadata.
When not lossless, the advanced encoding / decoding engine resident on the new ASIC developed for EVO II Encoders and Decoders applies a limited, ultra-light compression, composing an artifact free image upon decoding, including Dolby Vision or HDR10+ content.
