A method of synchronizing first and second streams of a multimedia content program is operable for determining a temporal difference indicative of a relative timing between first and second streams of the program, the first stream being provided to a first multimedia processing resource and the second stream being provided to a second MPR. The wave movement, up and down, between crest and trough causes movement of the piston, and the movement may be used to generate electricity when the piston is coupled with one or more electrical generating devices, such as a generator. The orientation of the PSPs of the signal in each element relatively to the principal axes of the element is controlled, such that a change in orientation between the first and second elements is equal and opposite to a change in orientation between the second and third elements. The CSIU also provides one or more commands understandable by the cloud-based data storage service, to migrate the metadata to the cloud-based data storage service independently of the files or file folders, so that they are usable by the cloud-based storage service without being moved to the cloud-based storage service. The method of tensioning the winch line includes feeding a lead in end of the winch line through the drum, manually pulling the lead in end through the rotating drum removing slack, and rotating the drum. In each subfield, a non-selected line on which all the discharge cells are not subjected to selective discharge is detected, and pixel data writing scanning is performed only to display lines excluding such non-selected lines.
