Abstract
A communication system, method and apparatus which can maintain favorable communication quality without imposing much burden upon a user. A plurality of communication networks are formed between first and second communication apparatus. Upon starting communication between the first and second apparatus, communication quality of the communication networks is measured using at least one of the communication apparatus. One of the communication apparatus is selected for communication based on a result of the measurement. The first and second apparatus may be a base apparatus and a portable terminal apparatus, respectively, for use in the home, in which the base apparatus receives a television broadcast and transmits a selected television program of the broadcast to the terminal apparatus for display thereon. The communication networks may include a radio network and a wireline network. The terminal apparatus may also be adapted to access the Internet via the base apparatus.
