The present disclosure relates to a server apparatus, a base station, and a terminal apparatus as well as a communication system that make it possible to implement stabilized communication against a fluctuation of a communication environment in a wireless LAN by switching a base station taking an event into consideration. An application server delivers information relating to an event, which differs for each base station depending upon an installed position, to a terminal apparatus through a base station together with base station information including communication quality and functions of the base station. The terminal apparatus selects a base station with which connection should be established, on the basis of the event information and the base station information and switches the connection. The present disclosure can be applied to a communication system in a wireless LAN.

When a signal path in a signal outputting device is changed, the signal outputting device indicates signal path change information representing the change in the signal path to a signal inputting device. Based on the signal path change information, the signal inputting device adaptively changes a signal path between the signal outputting device and the signal inputting device. The signal inputting device can know the signal path in the signal outputting device easier than heretofore, and can simply change the signal path between the signal outputting device and the signal inputting device.

Required power consumption is reduced for communication between communication devices connected to a network by an IEEE 1394 bus line. When the network includes communication in a synchronous communication mode and communication in an asynchronous communication mode, a power supply for a communication process in the synchronous communication mode is controlled independently of a power supply for executing a communication process in the asynchronous communication mode. Similarly, the power supply for executing the communication process in the asynchronous communication mode is controlled independently of the power supply for executing the communication process in the synchronous communication mode.
