CI-P: Shared Open-Source Tools in Support of Multimedia Systems Research

这个社区基础设施规划（CI-P）项目将重点规划一个社区基础设施项目，以开发一个多媒体工具包，帮助促进多媒体系统和网络研究。提出的多媒体工具包将解决多媒体系统社区面临的一些问题。通过提供一个更注重可读性、模块化和易于修改的工具包，我们期望这样一个工具包将有助于减少培养新研究生成为多媒体研究人员所需的时间，并允许他们更容易地创建新技术，而不是对目前使用的高度优化的、脆弱的软件工具进行修改。早期的多媒体工具包，如Berkeley MPEG-1工具或20世纪90年代的Open Mash工具，通过提供一组工具，使实验部署、测试和测量多媒体系统相对容易，从而促进了多媒体社区的研究。然而，像H.264 / MPEG-4和H.265 / HEVC这样的视频压缩标准的相继出现，由于压缩工具的高度复杂性，对实验性视频系统和网络项目的能力以及在教育环境中使用最新标准的能力产生了负面影响。该项目将通过一个多媒体工具包来解决这一问题，其目标如下：-显著减少培训时间，使学生能够快速掌握最新的视频压缩和解压缩工具；-使视频编码算法能够更快速地修改，并提供更快地构建新的多媒体系统的能力；-为研究社区提供几个配置文件，以便更容易地比较不同研究项目的结果。这个支持多媒体系统的开源工具的规划阶段包括：(i)调查和收集研究界对他们的研究和学生教育的需求，（ii）设计整体架构，以及（iii）征求社区对工具包的进一步反馈。

This Community Infrastructure-Planning (CI-P) project will focus on planning for a community infrastructure project to develop a multimedia toolkit to help catalyze multimedia systems and networking research. The proposed multimedia toolkit will solve a number of problems faced by the multimedia systems community. By providing a toolkit that is focused more on readability, modularity, and ease of modification, we expect that such a toolkit will help to decrease the time it takes to train new graduate students to become multimedia researchers and allow them to more readily create new technology rather than making modifications to highly-optimized, brittle software tools that are used today.Early multimedia toolkits such as the Berkeley MPEG-1 tools or Open Mash tools from the 1990s helped to catalyze research in the multimedia community by providing a set of tools that made it relatively easy to experimentally deploy, test, and measure multimedia systems. The succession of video compression standards like H.264 / MPEG-4 and H.265 / HEVC, however, has had a negative impact on the ability to do experimental video systems and networking projects as well as the ability to use recent standards in an educational setting due to the high complexity of the compression tools. This project will address this through a multimedia toolkit with the following goals: - Significantly reduce training time to bring students up to speed on the latest video compression and decompression tools, - Enable more rapid modifications to video coding algorithms and provide the ability to more quickly build new multimedia systems, and - Provide several profiles for the research community to use so that results across different research projects can be more readily compared.The planning phase of this open source tool in support of multimedia systems includes: (i) surveying and gathering the needs of the research community with respect to their research and the education of their students, (ii) designing the overall architecture, and (iii) soliciting further feedback from the community with regards to the toolkit.
