A minnow bucket that includes a bucket base and an automatic dispensing device positioned inside the bucket base that when raised on a vertical axis in relation to the bucket base dispenses at least one minnow. During encoding, prediction is performed on an image block to produce residual data of the image block, and the residual data of the image block is selectively coded into a residual difference from residual data of a block of a base layer, which spatially corresponds to the image block and is present in a base layer frame temporally coincident with a frame including the image block. Subsequently, a set of coordinates associated with a particular location of a monitored device are identified and rotated by the previously determined angle.
