The outstanding performance of Xilinx FPGA platform and the simple and easy-to-use Vivado™ development tools help Xiaoniao Technology to increase the performance of industry-leading professional audio and video solutions by 1.5 times and bring them to the market half a year ahead of schedule
Various large, medium and small command/video control centers and KVM seat management systems are like human brains that command whole-body actions. They act as core dispatchers in command city operation centers at all levels, command centers in various industries, and large, medium and small conference room clusters. character of. Therefore, clear picture quality and real-time video stream, as an important basis for the brain to collect, organize and analyze data for decision-making or real-time interaction, require a very professional audio and video processing system to provide full frame rate lossless ultra-high-definition audio and video support.
Traditional centralized matrix products can only support a hundred channels of signals at the largest scale, and need to cascade multiple units to realize large-scale signal switching, which is complicated in operation and poor in ease of use. The emergence of distributed products effectively solves the scale bottleneck that traditional centralized matrix products can only support up to 100 channels of signals, and has become a very widely used command and control system solution for small and medium-sized command centers in various industries in China. However, as application scenarios such as command rooms and control rooms have higher and higher requirements for video quality, delay, capacity, and reliability, distributed lossy codec algorithms such as H.264 and H.265 are often used. Compared with centralized products, the products have greater disadvantages in terms of image quality and delay. They are increasingly unable to meet the needs of the above-mentioned industries.
Xiaoniao Technology, a pioneer in distributed products, uses Xilinx Kintex-7 and Kintex UltraScale+ series platforms as its core devices. With the help of the device’s outstanding performance, ultra-high BRAM resource utilization and integration advantages, it has innovatively launched non-destructive Distributed product-UniStream, not only solves the problem of the scale of centralized matrix products, but also ensures the ultra-high image quality and ultra-low latency of the video signal.

The Xilinx product series mainly meet the development needs of Xiaoniao Technology in the following five aspects:
Performance: The outstanding IO performance and external memory performance of Xilinx Kintex-7 and Kintex UltraScale+ series FPGAs far exceed those of other competitors, making UniStream a cost-effective 4K60 lossless distributed solution in the industry, and fully meets the 4K60 ultra-high Video processing bandwidth requirements.
In terms of resources: video processing algorithms require a large amount of block RAM (BRAM) for caching. The excellent BRAM performance and ultra-high utilization rate of the Xilinx platform makes UniStream’s algorithm processing an increase of 1.5 times compared with the previous generation products.
In terms of integration: Xilinx FPGA’s rich logic resources, excellent IO and Memory performance, excellent BRAM and DSP performance, and complete Ethernet solutions enable Xiaoniao Technology to integrate many functions such as video processing and Ethernet transmission. Based on a single chip, UniStream achieves high energy efficiency with a single node power consumption of less than 15W
Reliability: The ultra-high reliability of Xilinx FPGA platform provides UniStream with ultra-high reliability of stable operation for 7*24 hours.
Flexibility: Xilinx’s unique flexibility based on dynamic function conversion (DFX) technology and software and hardware OTA online upgrade functions provide valuable cost and efficiency for Xiaoniao Technology and its users to adapt to future technological evolution and remote maintenance Advantage.
Mr. Li Hupeng, CEO of Xiaoniao Technology, said, “The outstanding performance of Xilinx FPGA platform and the simple and easy-to-use Vivado development tools provide us with important support for the rapid development of industry-leading professional audio and video solutions and the first to market them. “
With the help of Xilinx FPGA platform and the strong support of Xilinx and its channel partner Avnet’s sales and technical experts, Xiaoniao Technology’s lossless distributed product UniStream was able to go on the market 6 months ahead of schedule, and was quickly obtained in industries such as accusations and conferences. Widely recognized and deployed.
One of the successful deployment cases is a municipal government office park project. All the intelligent departments in the park, the city brain, the police joint service building, etc., all adopt the overall solution of Xiaoniao audio and video. A total of more than 40 conference rooms adopt a networked distributed system to achieve cross-floor and entire campus-level signal interconnection, breaking the signal island problem; the emergency command center and the armed police command center use optical fiber architecture to ensure stable operation and data security At the same time, the emergency response efficiency of the command center has been greatly improved.
