Cloud-computing has emerged as a scalable and cost effective platform for delivering digital media content and**has the potential to revolutionize the video gaming industry. In cloud gaming, the computational cost of**rendering the game is moved from the player's gaming device to a remote cloud-server. This enables players to**play games without the need of installing it on their devices. Besides, it makes games available to a larger**group of users by removing the gaming hardware constraint and allows users to access the game using a**simpler setup. However, the main challenge that affects the quality of experience in cloud gaming is the visual**quality of the gaming video rendered on the cloud and streamed to the player over the internet. Under bad**network conditions and bandwidth fluctuations, the gaming video quality degrades due to heavy compression**performed by the video encoder at the cloud. In this research project, we propose an "encoder-friendly"**rendering solution, that will enable the game engine, running on the cloud, to adapt its rendering complexity,**frame rate and frame resolution, so it would improve the quality of video streamed to the player at any network**condition. This will improve game pliability and thus the user quality of experience. The Canadian video game**industry is a significant portion of the Canadian Digital Economy and the emergence of cloud-gaming has the**potential to dramatically improve the gaming experience and thus boost the Canadian video game market even**further.

云计算已经成为一个可扩展的和具有成本效益的平台，用于提供数字媒体内容，** 有可能彻底改变视频游戏行业。在云游戏中，** 渲染游戏的计算成本从玩家的游戏设备转移到远程云服务器。这使得玩家可以 ** 玩游戏，而无需在他们的设备上安装它。此外，它通过消除游戏硬件限制，使游戏可供更大 ** 的用户群使用，并允许用户使用更简单的设置访问游戏。然而，影响云游戏体验质量的主要挑战是在云上渲染并通过互联网流式传输给玩家的游戏视频的视觉质量。在恶劣的 ** 网络条件和带宽波动下，由于云端视频编码器执行的大量压缩 **，游戏视频质量会下降。在这个研究项目中，我们提出了一个“编码器友好”的 ** 渲染解决方案，它将使运行在云上的游戏引擎能够适应其渲染复杂度，** 帧速率和帧分辨率，因此它将提高在任何网络条件下传输给玩家的视频质量。这将提高游戏的灵活性，从而提高用户体验质量。加拿大视频游戏产业是加拿大数字经济的重要组成部分，云游戏的出现有可能极大地改善游戏体验，从而进一步推动加拿大视频游戏市场。
