EAGER: REAQTIVE - Resource Aggregation and Quality Tradeoffs for Integration of Video projector Ensembles

这项研究的目的是集成多个质量受限的基于手机的微微投影仪，以创建高质量的输出，并改善用户在多媒体会话期间的观看体验，即观看视频或共享多媒体演示文稿。建议的方法是开发编码和解码方案，以允许灵活的拆分流媒体传送，该方案考虑用于图像分割的显示器的数量，并适应分辨率、帧速率和设备功率资源的范围。此外，还将研究跨多个设备集成显示同步和视频/音频流同步的新型同步方案。当前的多投影仪配准技术需要针对低质量微微投影仪的资源和质量敏感性进行修改。该项目提出了一种用于便携式多媒体设备的资源管理、设备同步和视频编解码的新范例，以协作地为用户提供增强的观看体验，其中，增强的是指帧速率、图像分辨率、亮度、音频质量和更长时间观看的节能。通过在视频显示中引入空间分集，该范例与无线通信中的MIMO概念平行。MIMO提高了数据速率和/或信号质量，本项目的成果有望提高图像的分辨率和/或亮度。所提出的范例将允许多个用户集中移动便携设备的资源，以产生更高质量、能量/资源高效的输出，随时随地。这将对临时环境中的用户产生影响，从社交环境中的媒体共享到现场需要更高质量图像输出的急救人员和急救人员。

The objective of this research is to integrate multiple quality-constrained cell-phone-based pico-projectors as to create quality output and improve the viewing experience of users 'on the go' during a multimedia session, i.e., watching a video, or sharing a multimedia presentation. The proposed approach is to develop coding and decoding schemes to allow flexible split stream media delivery that takes into account the number of displays for image partitioning and accommodates a range of resolutions, frame rates, and device power resources. Additionally, novel synchronization schemes that integrate display synchronization and video/audio stream synchronization across multiple devices will be investigated. Current multi-projector registration techniques need to be modified for resource and quality sensitivity for use in low-quality pico-projectors.The project proposes a new paradigm of resource management, device synchronization and video coding/decoding for portable multimedia devices to collaboratively deliver an enhanced viewing experience for users, where 'enhanced' refers to frame rate, image resolution, brightness, audio quality, and power savings for longer viewing. This paradigm parallels the MIMO concept in wireless communications by introducing spatial diversity in video display. MIMO enhances the data rate and/or the signal quality, the results of this project is expected to enhance the image resolution and/or brightness.The proposed paradigm will allow multiple users to pool the resources of mobile portable devices to produce a higher quality, energy/resource efficient output, anywhere, anytime. This will impact users 'on the go' in ad hoc settings, ranging from media sharing in social milieus to first responders and emergency workers requiring higher quality image output in the field.
