Abstract: A multimedia contents service system transforms original contents based on selected user preferences chosen by a user or automatic preferences generated from accumulated statistics on user's contents consumption. The system transmits the transformed contents to the user and provides services which perform rendering or storing according to user preferences. Therefore, the system provides contents transformed according to user's interests to thereby increase user's convenience (universal multimedia access) and satisfy a variety of user's demands.

Abstract: A system for forming a periodic pulse pattern in a sample includes a movable stage having the sample loaded thereon, a pulse laser for generating a laser beam of pulses, an objective lens for focusing the laser beam to the sample to form a pattern of pulses in the sample, and a controller for adjusting the movement speed of the movable stage to set a period of the pulse pattern. The pulse pattern includes a spot pattern or a line pattern made by a slit provided between the pulse laser and the objective lens.
