The present invention relates to a flow spreading mechanism, in particular a flow spreading mechanism used with refrigerators or air conditioners to enhance spreading of cool or warm air. According to the invention, a portion of a live stream is forwarded from a first node to a second node in a transport network at a high bitrate as compared to the stream’s encoded bitrate, and thereafter, the stream continues to be forwarded from the first node to the second node at or near the encoded bitrate. The preferred output image form is indicated. The coil assembly further includes at least one coil that produces a signal representative of the vibration of the at least one magnet.
