Disclosed is a method, circuit and system for communication channel scanning by a video transceiver to determine whether a connection is being requested by another video transceiver. Scanning for connections requests may be performed according to two modes: (1) a first (complete) scanning mode, and (2) a second (partial) scanning mode. The information collected and/or recorded during a scanning sequence in the first scanning mode may be used as part of one or more partial scanning sequences performed in the second scanning mode. A scanning sequence in a first scanning mode may be followed by one or more (e.g. one, two, three etc.) scanning sequences in a second scanning mode. There may be provided a scanning circuit for checking for connection requests on one of a set of channels.
