AllCast

影响向移动设备分发内容的各方，以及那些寻求围绕这些内容提供创收服务的各方的一个关键问题是，尽管显示技术在进步，但用户通常很难以一种视觉上令人满意的方式访问内容。这是由于显示技术和功耗限制以及环境观看条件的变化。在户外观看内容通常是不可能的。AllCast项目的目的是基于现有的MPEG4/H创建一个新的编解码器。264标准实现了对最终用户观看体验的准确管理和可预测性，同时视觉质量也得到了普遍改善。它基于将先进的动态范围校正和降噪技术（Apical Imaging Ltd.的Irridix）可逆地应用于传输的视频，并将控制元数据嵌入到额外的编解码通道中，从而在显示端重建原始内容，同时在环境观看条件下最佳地呈现屏幕特征。在上述项目中，拉夫堡大学（LU）的研究团队将负责视频CODEC基础设施的设计、实现、测试和优化。特别是LU团队将根据预处理阶段产生的编码参数创建元数据，并确保其高效表示、编码、传输和交付到解码器端，使后处理模块能够将解码后的视频与显示特性相匹配。此外，LU团队将在最终系统的集成、软件和硬件模型的优化以及硬件范围方面支持工业合作伙伴。此外，研究小组将负责在项目的不同阶段对相关文献进行适当的审查，并传播学术成果。

A key problem affecting all parties involved in distributing content to mobile devices, and those seeking to provide revenue-generating services around such content, is that despite advances in display technology, it is often difficult for the user to access content in a visually satisfying manner. This is due to a combination of display technology and power consumption limitations and variations in ambient viewing conditions. It is frequently impossible to view content outdoors. The aim of the AllCast project is to create a new codec based on the existing MPEG4/H.264 standards enabling accurate management and predictability of the end user viewing experience, together with a general improvement in visual quality. It is based on applying sophisticated dynamic range correction and noise reduction technology (Irridix of Apical Imaging Ltd.) reversibly to the transmitted video, and embedding control metadata into the additional codec channels enabling reconstruction of the original content at the display-side, while rendering it optimally to the characteristics of the screen under ambient viewing conditions.Within the above project the Loughborough University (LU) research team will be responsible for the design, implementation, testing and optimization of the video CODEC infrastructure. In particular the LU team will create metadata from coding parameters generated from the pre-processing stage and will ensure their efficient representation, coding, transmission and delivery to the decoder end, allowing the post processing module to match the decoded video to the display characteristics. Further the LU team will support the industrial partners in the integration of the final system, optimization of the software and hardware models and in hardware scoping. In addition the LU team will be responsible for carrying out reviews of relevant literature as found appropriate at various stages of the project and in the dissemination of academic findings.
