The SEQUOIA project is a response to the emerging imperative needs for more financially and environmentally-sustainable high-quality video streaming. Project activities are aimed at addressing exploding market demands, and address the challenges faced by the media sector in tackling the **surge in online media consumption**, which is posing **unprecedented stress on Internet services**, while also greatly **contributing to the environmental footprint left behind by media services**.Disruptive innovation for video streaming is urgently needed - new pre/post processing, encoding, and delivery tools that are device-aware and cross-codec compatible - to meet growing demands for online video reducing processing, energy and storage requirements. The SEQUOIA scientific innovation will result in a "**deep perceptual optimiser**" leveraging: (i) latest advances in psychovisual/perceptual models (ii) cutting-edge AI/deep-learning and (iii) state-of-the-art video coding, optimising quality, bitrate and environmental impact of video services.Building on the partners' expertise on perceptual quality optimisation, video pre/post processing, video coding and deep learning, SEQUOIA will go beyond state-of-the-art to develop new AI-based video quality **analytics, streaming and encoding.** As a result, the SEQUOIA vision is to develop an automated **deep perceptual optimiser** to make an impact throughout all stages in the media distribution chain.The project will demonstrate its results on operational and portable encoder designs, applicable both to Video on Demand (VOD) as well as live applications and encoding social media streams. The value of such scientific innovation will lead to benefits for the whole sector, demonstrating technology to enable sustainable distribution of Ultra High-Definition (UHD) content, while limiting the impact of video on internet traffic and reducing distribution costs. Extending beyond the commercial benefits, the project outcomes will be devised to support **environmentally conscious solutions by monitoring and proactively reducing energy consumption** at all stages within the media value chain.Extending over a period of 24 months, the project brings together industrial (iSIZE and BBC) and academic (QMUL) partners. The partners bring unique expertise on **AI, video coding standardisation, adaptive video pre/post processing and streaming, perceptual optimisations and interoperable software architectures**, to collaboratively work towards these challenging objectives.

SEQUOIA项目是对新兴的迫切需求的回应，这些需求是对更具经济和环境可持续性的高质量视频流的需求。项目活动旨在满足爆炸式增长的市场需求，并解决媒体部门在应对 ** 在线媒体消费激增 ** 方面面临的挑战，在线媒体消费对互联网服务构成 ** 前所未有的压力 **，同时也极大地 ** 促进了媒体服务留下的环境足迹 **。迫切需要对视频流进行颠覆性创新--新的预/后处理、编码、以及设备感知和跨编解码器兼容的交付工具，以满足不断增长的在线视频需求，降低处理、能源和存储要求。SEQUOIA的科学创新将产生一个“** 深度感知优化器 **”，利用：（i）心理视觉/感知模型的最新进展;（ii）尖端的人工智能/深度学习;（iii）最先进的视频编码，优化视频服务的质量、比特率和环境影响。基于合作伙伴在感知质量优化、视频预/后处理、视频编码和深度学习方面的专业知识，SEQUOIA将超越最先进的技术，开发新的基于AI的视频质量 ** 分析、流媒体和编码。因此，SEQUOIA的愿景是开发一个自动化的 ** 深度感知优化器 **，在媒体分发链的各个阶段产生影响。该项目将展示其在可操作和便携式编码器设计方面的成果，适用于视频点播（VOD）以及直播应用和编码社交媒体流。这种科学创新的价值将为整个行业带来好处，展示能够实现超高清（UHD）内容可持续分发的技术，同时限制视频对互联网流量的影响并降低分发成本。除了商业利益之外，该项目的成果还将通过监测和主动减少媒体价值链中所有阶段的能源消耗来支持 ** 环保解决方案。该项目为期24个月，汇集了工业（iSIZE和BBC）和学术（QMUL）合作伙伴。合作伙伴在 ** 人工智能、视频编码标准化、自适应视频预/后处理和流媒体、感知优化和可互操作的软件架构 ** 方面拥有独特的专业知识，共同努力实现这些具有挑战性的目标。
