1. A method of providing signals by way of a network from a remote site to a local site where the provided signals are provided in accordance with controls generated at the local site, the method comprising: causing acquisition from sensors at the remote site of first signals representing relatively rich information about real aspects of the remote site; causing processing at the remote site of the first signals representing the relatively rich information, the caused processing utilizing relatively rich signal processing resources present at the remote site, the caused processing producing second signals representing relatively less rich information about real aspects of the remote site where the less rich information can be transmitted over the network using less bandwidth than needed for transmitting the first signals representing the relatively rich information; causing transmission of the less rich information over the network from the remote site to the local site; and causing transmission of control signals generated at the local site to the remote site, the transmitted control signals controlling said processing at the remote site of the first signals.
