摘要： In various embodiments, a screen image may be divided into rectangles, and a capture component may track changed rectangles and capture the screen upon receiving an indication. For small screen updates, the capture rate may be set to ˜30 captures per second to provide a lower latency. As the screen update size increases, the capture rate may be decreased to match an allocated bandwidth. The capture rate may be increased when available bandwidth increases and decreased as bandwidth decreases. For example, the capture rate may be decreased when downstream back pressure meets predefined criteria. The capture rate change may be effected gradually to avoid jerks and jumps. Varying the capture rate by also enable audio/video synchronization with varying bandwidth variations. Some embodiments may be extended to multiple monitor solutions.
