Live video distribution innovator Zixi is enhancing the efficiency of its software platform as part of a broader drive to encourage sustainability in broadcast & media

he vision of a media landscape full of highly efficient and sustainable

businesses is widely shared. But in terms of demonstrating a meaningful way forward for vendors and software companies in particular, there is no question that live video distribution innovator Zixi has been a trailblazer. With more than 1000 media customers and 400 partners, Zixi’s Software-Defined Video Platform (SDVP) provides a comprehensive modular platform for live video distribution. Designed to work with any IP-based technology – although delivering the greatest efficiencies when deployed with Zixi’s own protocol – SDVP comprises five main elements: ZEN Master (control plane), Zixi Broadcaster (media gateway), Live Video Transcoding (transcode option), Intelligent Data Platform (AI/ ML analytics) and Zixi Edge Compute (high-performance connectivity). Zixi executive chairman and CEO Gordon Brooks confirms the centrality of energy efficiency to its sustainability goals, and reveals the most recent development revolves around a shift to the use of ARM chips with the latest version (V16) of Zixi Broadcaster. “ARM processors require 50% less energy, and cost 50% less than other processors,” says Brooks. “Already a huge improvement in efficiency – increasing even more when our own protocol is used.” A brief look at the statistics confirms the resulting boost to energy efficiency. “Compared with a software using SRT as an example, Broadcaster V16 is 4.4x more efficient when transporting live video,” explains

Brooks. “When we launch V17 in time for IBC 2023 later this year, that figure will rise to 14x more efficient. Moreover, these efficiencies carry forward to ARM, which creates a multiplier effect (throughout the distribution workflow). It’s important to note the Zixi Protocol compresses null packets and is video aware, resulting in a bit-rate requirement of 50% – this is network-efficient and cuts cloud egress by 50%.” FULLY FOCUSED ON SUSTAINABILITY For Zixi, this is only the latest in a series of measures designed to boost the efficiency and sustainability of its many solutions. “We have been very focused on these areas for the last three or four years,” says Brooks. “You could summarise it briefly as giving our customers the ability to do more with less! Sustainability is becoming more important for many customers, but
