    Abstract: A method, computer readable medium, and system are disclosed for monitoring a pipeline to detect anomalies such as unusual latency associated with a particular stage. Each stage of the pipeline is configured to update metadata associated with content being processed by inserting a time stamp into the metadata when processing of the content is completed by the stage. The server device can collect the metadata from the last stage of the pipeline and analyze the metadata in order to generate metrics for the pipeline, including a residual latency and/or a gain for each stage of the pipeline. In an embodiment, the content is a frame of video to be displayed on a client device after being rendered by a server device, such as through a streaming service (e.g., a video game streaming service). The server device can adjust the pipeline based on the metrics to improve performance.

    Abstract: Embodiments of the present invention provide a low-latency approach for local or remote application streaming that reaches high FPS targets without overloading the available streaming bandwidth, for example, by limiting the bit rate to the same value that is used by traditional 60 FPS streaming solutions. A client device and server device cooperate to actively monitor and control a video stream to maintain an acceptable balance between latency and video quality by adjusting the frequency or resolution when necessary to improve the streaming experience. When the server device captures and transmits frames at a higher rate, the software stack executing on the client device is able to display frames with less delay, even on a display device limited to 60 Hz, thereby achieving additional latency reduction.
