A motion video signal encoder maximizes image quality without exceeding transmission bandwidth available to carry the encoded motion video signal by comparing encoded frames of the motion video signal to a desired size of frame. In accordance with an embodiment, one or more computer monitors are used with a closed-path configuration, in which there are no, e. The control system monitoring apparatus is configured to read, record, and process pressure data supplied by the surface manifold and surface control line pressure transducers. Systems and method of displaying recorded network data utilizing the retrieval systems are also included in the invention. The incrementing or decrementing is continued until the frequency error approaches a minimum value.
