In this locality, preestablish the function implementation strategy of each customizing functions information correspondence, realize each function by carrying out this function implementation strategy; Obtain colouring information according to the predefined function implementation strategy corresponding with customizing functions information;
Each strategy is realized different functions, and is concrete:
Strategy one:
From the data that server end receives, obtain first data;
Obtain corresponding colouring information according to these first data;
For example, what the user selected is the temperature prompt facility, and the keyword of user's input be " temperature " and " Shenzhen ", according to keyword " temperature " and " Shenzhen " from from searching for the current temperature in Shenzhen the data of server end; In advance temperature is divided into several grades, for example less than 10 degrees centigrade be cold, more than or equal to 10 degrees centigrade and less than 15 degrees centigrade for colder, more than or equal to 15 degrees centigrade and less than 25 degrees centigrade be comfortable, more than or equal to 25 degrees centigrade and less than 30 degrees centigrade for hotter; More than or equal to 30 degrees centigrade be hot, and each grade is to there being different colouring informations, for example grade is from cold to the sweltering heat, corresponding color is from shallow to deep; Find corresponding grade according to the temperature that searches, find corresponding colouring information according to this grade then;
And for example, what the user selected is the strong and weak prompt facility of programme signal, in this locality, sets in advance the colouring information of each signal strength signal intensity correspondence, and main control chip obtains the strong and weak information of signal of current program, and the strong and weak information searching of this signal is arrived corresponding colouring information;
