Abstract: An approach is provided in which the approach builds a combination model that includes a normal status model and an abnormal status model. The normal status model is built from a set of time-sequenced normal status records and the abnormal status model is built from a set of time-sequenced abnormal status records. The approach computes a set of time-sequenced coefficient combination values of the normal status model and the abnormal status model based on applying a set of fitting coefficient characteristics to the normal status model and the abnormal status model. The approach performs goal seek analysis on a system using the combination model and the set of time-sequenced coefficient combination values.

Abstract: An apparatus for switching television channels and a method thereof are provided. The apparatus for switching television channels includes a tuner unit, at least two video de-multiplexing modules and a switch unit. The tuner unit locks a specific frequency point in a broadcast stream, and the frequency point has at least two program channels. After the tuner unit locks the specific frequency point, each of the video de-multiplexing modules simultaneously and respectively receives the broadcast stream, and performs a de-multiplexing operation and a decoding operation to each of the program channels to generate at least two program streams. The switch unit selects and displays one of the at least two program streams corresponding to a first program channel, and when a second program channel is selected, the switch unit selects and displays the other one of the at least two program streams corresponding to the second program channel.
