A control method for a web phone includes: a) determining all possible operating states of the web phone, and transition conditions that control transition from one of the operating states to another of the operating states; b) performing state analysis for the operating states in accordance with the transition conditions to generate a state transition table; c) determining a logical function in canonical sum-of-products form for each bit of an n-bit number that is used to represent the operating states from the state transition table; and d) implementing a finite state machine in accordance with simplified equivalents of the logical functions thus obtained such that the finite state machine can control transition of the web phone from one of the operating states to another of the operating states in accordance with current values of the transition conditions. A control apparatus including the finite state machine is also disclosed.
