A method, system and apparatus of lossy compression technique for video encoder bandwidth reduction using compression error data are disclosed. For example, a masking unit may receive a request vector and provide a masked request vector, wherein each bit in the request vector represents a requestor and indicates if that requestor is requesting a resource. The liner has a liner base portion extending along the base wall and a peripheral portion extending along the inside surface of the lip. The borehole may be driven sinking or raising.
