A content collection part compares the transmission rate (TD) inputted from a transmission rate monitoring part with a threshold value (C&minus;&agr;) in response to a start operation by a user. When a condition TD<(C&minus;&agr;) is satisfied, the content collection part starts an automatic content collection part to perform a background process to collect URL contents which were set up beforehand from a Web server. When the user designates URL contents, the content collection part controls the automatic content collection part to terminate the background process and enters a foreground process to collect the designated URL contents.

To drive a liquid crystal panel without producing flickering or noise on a screen, an adder circuit 26 adds the noise component of the analog signal detected in a filter 24 to a reference voltage from a power supply 16, and a phase adjustment circuit 28 adjusts the phase of the reference voltage to which the noise component was added. A circuit 12 holds the analog signal and outputs it to comparators 14.sub.1 to 14.sub.n. The reference voltage from the circuit 28 is divided in resistors 18.sub.1 to 18.sub.n+1 and output to comparators 14.sub.1 to 14.sub.n as threshold voltages TV.sub.1 to TV.sub.n. The comparator 14 compares the input analog signal to the voltage TV, and outputs a predetermined signal to an encoder 20 if the analog signal is greater than the voltage TV. The encoder 20 converts the signal from the comparator 14 to a digital signal and applies it to the electrode of a liquid crystal panel.
