Abstract:
A performance metrics of a receiver is obtained using frames of an application hosted by a server that are received via a network. The one or more performance metrics include information indicative of a current occupancy of a frame buffer corresponding to the receiver and information indicative of a target occupancy of the frame buffer corresponding to the receiver. The frame buffer of the receiver is used to queue frames of the application for display. A frame rate associated with rendering at least one next frame of the application is adjusted using the one or more performance metrics of the receiver to control population of the frame buffer. Subsequent frames of the application hosted by the server are rendered using the adjusted frame rate. Upon rendering the subsequent frames, the server sends the subsequent frames to the receiver for display.
