Abstract
In server-client system, such as an IKVM, where a server and a client are connected via a network, an ROI (region of interest) function is provided which allows an ROI area of the video image displayed on the client to have higher image quality and/or magnification than the rest of the image. The client defines an ROI area and transmits the ROI parameters to the server. The server processes video data in the ROI area and non-ROI area differently in various stages of video data processing, including video data sampling/scaling, processing, compression, and transmission, so that the image in the ROI area has a higher image quality and/or magnification. The client may also cooperate with the server to accomplish the ROI function, such as by performing image enhancement processing of the ROI area during image display.
