Exemplary embodiments include an interception mechanism for rendering commands generated by interactive applications, and a feed- forward control mechanism based on the processing of the commands on a rendering engine, on a pre-filtering module, and on a visual encoder. Also a feed-back control mechanism from the encoder is described. The mechanism is compression-quality optimized subject to some constraints on streaming bandwidth and system delay. The mechanisms allow controllable levels of detail for different rendered objects, controllable post filtering of rendered images, and controllable compression quality of each object in compressed images. A mechanism for processing and streaming of multiple interactive applications in a centralized streaming application server is also described.
