Abstract: Methods and systems for optimizing and enhancing remote graphics on client devices are presented. A client device may determine a visual focus region of a display of the client device based on a user input. A server may receive, from the client device, data regarding the visual focus region of the display. The server may determine a first subset of an image that corresponds to the visual focus region of the display and a second subset of the image that is external to the visual focus region of the display. The server may apply a lossless encoding to the first subset and a lossy encoding to the second subset. The server may then transmit, to the client device, the first subset through a first channel and the second subset through a second channel, wherein the first channel comprises a higher network bandwidth allocation than the second channel.

Abstract translation: 介绍了客户端设备优化和增强远程图形的方法和系统。 客户端设备可以基于用户输入来确定客户端设备的显示器的可视聚焦区域。 服务器可以从客户端设备接收关于显示器的视觉焦点区域的数据。 服务器可以确定对应于显示器的视觉焦点区域的图像的第一子集，以及在显示器的视觉焦点区域外部的图像的第二子集。 服务器可以向第一子集应用无损编码，对第二子集应用有损编码。 服务器然后可以通过第一信道和第二子集通过第二信道向客户端设备发送第一子集，其中第一信道包括比第二信道更高的网络带宽分配。
