Xilinx has introduced two real-time computing video appliances for easy-to-scale, ultra-high-density video transcoding applications.

Based on its Xilinx Real-Time (RT) Server reference architecture, these new appliances will enable service providers to optimize video quality and bitrate at the lowest cost per channel for significant TCO savings over both software-based and fixed-architecture approaches.

Designed for edge and on-premise compute-intensive workloads where video channel density, throughput and latency are critical requirements, the appliances are available in two pre-configured options integrating Xilinx Alveo data center accelerator cards; the high channel density video appliance and the ultra-low bitrate video appliance.

Developed to deliver the lowest cost per channel, the high channel density video appliance integrates up to eight Alveo U30 data center acceleration cards, also launching today. The Alveo U30 card is powered by the Zynq UltraScale+ MPSoC with integrated video codec and graphics engines for ultra-high-definition video. The U30 card supports both the H.264 and HEVC (H.265) codecs and is capable of streaming up to sixteen 1080p30 channels per card.

The ultra-low bitrate optimized video appliance is purpose-built for high-quality live video while reducing bandwidth costs. It contains up to eight Alveo U50 accelerator cards. Built on Xilinx UltraScale+ architecture and packaged in an efficient 75-watt, low-profile form factor, the Alveo U50 card includes 8GB HBM2, 100GbE networking and a PCI Express 4.0 interconnect. It is capable of streaming up to seven full-HD 1080p60 channels along with eight full ABR ladders (all at x265 medium preset). Both appliances offer up to a 4x reduction in cost, footprint, and power for H.264 at 1080p30 resolution and x264 medium preset.
