盡管目前萬兆網卡需求還是小眾需求，還是限于專有的行業前期8K UHD極清應用。隨著2D轉3D的光場相機采用復眼多角度傳感器，8K UHD分辨率, 數據量大呈井噴狀態，因此選擇優質的傳輸方式尤其重要.

目前業界普遍采用有線銅纜或多模光纜（相對單模更經濟些）方式傳輸4K UHD，HDMI2.0格式

昨天我在AI音視頻群里有分享了一些HDMI2.0 4K IP的傳輸交叉開關的解決方案

Semtech公司BlueRiver NT強大的Cross MATRIX Swithing over IP解決方案

采用了通用Xilinx FPGA的HDMI2.0(之后升級到HDMI2.1 8K UHD) IP解決方案成本是高了不少，因此需要對接口協議固化后進行ASIC的市場量化.

8K UHD IP以及萬兆以太網Matrix交叉及幾無延時的傳輸解決方案為8K光場攝像機鋪建了高速公路，從而得以起量遠航.

A true game changing technology for AV signal distribution, the BlueRiver NT chipset is the world’s first and only chipset to enable the extension, switching and compositing of real-time, uncompressed Ultra-HD signals with zero-frame latency over off-the-shelf IP switches. Replacing custom AV matrix switches with standard IP switches cuts the cost and size of such equipment by 60% while eliminating the associated R&D cost, reducing time-to-market and lowering inventory risk. Using a high-bandwidth, synchronous, packet-based architecture for pixel transmission, the BlueRiver NT chipset is capable of:extendinguncompressed Ultra-HD (4K) video, audio, GbE and other control signals over fiber or 100m Cat-x cabling;switchingthese signals through standard IP switches; andcompositingmultiple videos onto one or more displays. This FPGA-based chipset can easily be integrated into OEM designs for AV/KVM extension, switching, multi-view and video-wall applications. Ready-to-manufacture reference designs based on the chipset are available for qualified customers.
