Systems, methods, and software technology for optimizing the streaming video to end points while maintaining low latency. In an implementation, a streaming service receives video data for distribution to a plurality of end points. For each end point, the service streams the video data at a given bit rate to the end point. While the video is being streamed, the service sends test data to the end point at an additional bit rate. The service also increases the additional bit rate of the test data until a threshold decline in quality of the video data occurs or until a total bit rate of the video data and the test data reaches a next available bit rate for the video data. The service conditionally switches from the given bit rate to the next available bit rate if the total bit rate has reached the next available bit rate.
