A connection method for providing a remote real-time audio and/or video (AV) signal includes: when a connection request that corresponds to a selected AV terminal is received from a user terminal, determining whether the selected AV terminal belongs to an AV terminal group, which includes a plurality of AV terminals; if it is determined that the selected AV terminal belongs to the AV terminal group, establishing connections with the selected AV terminal and at least one other AV terminal in the AV terminal group, and forwarding the AV signal of the selected AV terminal to the user terminal; and in response to a switch command from the user terminal, forwarding the AV signal of another one of the AV terminals in the AV terminal group to the user terminal. A communication framework that performs the method is also disclosed.
