This Small Business Innovation Research (SBIR) Phase II project concerns the design, development and commercialization of systems for real-time measurement and enhancement of the quality of video distributed over emerging networks. The Phase I project has demonstrated the feasibility of a real-time version of an automatic video quality meter (AVQ) that has several novel features. By not requiring a reference to the source video, and by being compute-scalable, the AVQ meter can reside anywhere in the video distribution chain. In addition, AVQ scores correlate extremely well with subjective assessments of users, making it valuable not only as an accurate measurement tool, but also as the starting point for VQ Enhancement (VQE). This Phase II work will create an industry-ready suite of AVQ products that can reside in the network (AVQ-N), home (AVQ-H) and Set Top Box (AVQ-STB). It will also create solutions for video quality enhancement (VQE) that will reside in several network points. The AVQ and VQE products will depend on several innovations in design, including the retention of performance in the leaner versions of AVQ and VQE, and portability of a core AVQ engine into multiple PC-native, board-level and chip-level platforms.In rapidly emerging scenarios, video information is generated, gathered and distributed in real time, using a larger number of communication networks than ever before. Increasingly, users who are exposed to the notion of high-quality, high definition television will demand a high quality of video experience in all circumstances, in both fixed and mobile systems. The solutions proposed in this research will initially help content providers, aggregators, distributors and receiver manufacturers in meeting user expectations in emerging systems for entertainment video. These systems include cable and telco services as well as mobile and internet video.

该小型企业创新研究（SBIR）第二阶段项目涉及实时测量和增强新兴网络上分发的视频质量的系统的设计，开发和商业化。第一阶段的项目已经证明了实时版本的自动视频质量计（AVQ），具有几个新的功能的可行性。由于不需要对源视频的引用，并且是计算可伸缩的，AVQ计量器可以驻留在视频分发链中的任何地方。此外，AVQ分数与用户的主观评估非常相关，不仅作为准确的测量工具，而且作为VQ增强（VQE）的起点。第二阶段的工作将创建一个行业就绪的AVQ产品套件，可以驻留在网络（AVQ-N），家庭（AVQ-H）和机顶盒（AVQ-STB）中。它还将创建视频质量增强（VQE）解决方案，这些解决方案将驻留在多个网络点中。AVQ和VQE产品将依赖于设计上的几项创新，包括保留AVQ和VQE精简版本的性能，以及核心AVQ引擎到多个PC原生、板级和芯片级平台的可移植性。在快速出现的场景中，视频信息的生成、收集和分发是真实的，使用的通信网络数量比以往任何时候都多。越来越多地，接触到高质量、高清晰度电视概念的用户将要求在固定和移动的系统两者中的所有情况下的高质量视频体验。 本研究中提出的解决方案最初将帮助内容提供商、聚合商、分销商和接收器制造商满足新兴娱乐视频系统中的用户期望。这些系统包括有线电视和电信服务以及移动的和互联网视频。
