Abstract: Systems and methods are presented for compressing digital video signals in a manner that prevents the creation of block artifacts and improves compression efficiency by the selective re-moval of data representing visually imperceptible or irrelevant detail.  Bandwidth control is improved through prioritized removal of data exceeding permissible bandwidth limits. This provides a process by which a coupled compressor and de-compressor system can effect the transmission or storage of video at low bitrates with high perceptual quality of the decompressed video. In one embodiment, the low fre-quency components are removed from a video stream and either stored or transmitted in compressed format separate from the storage or transmission of the high frequency components of the video stream. Certain high frequency video stream details can be sup-pressed to further reduce bitrate.

Abstract: A system compensates for heave induced pressure fluctuations on a floating rig when a drill string or tubular is lifted off bottom and suspended on the rig, such as when tubular connections are made during MPD, tripping, or when a kick is circulated out during conventional drilling. In one embodiment, a liquid and a gas interface moves along a flow line between a riser and a gas accumulator as the tubular moves up and down. In another embodiment, a pressure relief valve or adjustable choke allows the movement of fluid from the riser when the tubular moves down, and a pump with a pressure regulator moves fluid to the riser when the tubular moves up. In other embodiments, a piston connected with the rig or the riser telescoping joint moves in a fluid container thereby communicating a required amount of the fluid either into or out of the riser annulus. The system also compensates for heave induced pressure fluctuations on a floating rig when a riser telescoping joint located below a RCD is moving while drilling.
