Abstract: A method of operating a solution searching system includes a utility server generating a model input file according to words in an issue description file, a model server generating a prediction solution classification according to the model input file and a data mining prediction model, a central server selecting a first user defined solution classification with a highest weighting of at least one of user defined solution classification stored in a relational database as a solution classification, a database server reading at least one solution from a big database according to the solution classification, and the central server outputting the at least one solution according to weighting of each of the solution.

Abstract: A multimedia stream displaying method is disclosed. The method includes the following steps: firstly, a portable decoder unit is embedded between an application layer and a hardware layer. Then, a specific stream format of the hardware layer is inquired. A plurality of multimedia streams from the application layer are received and decoded, and the decoded multimedia streams are encapsulated in the specific stream format. Finally, the encapsulated multimedia streams are transmitted to the hardware layer to be displayed.
