Abstract
A multi-image switching method is provided. The switching method includes steps of: establishing a connection between a portable device and a smart device, and fetching a program source list from the smart device; transmitting a watch request message to the smart device according to a user-selected program source from the program source list, wherein the watch request message includes program source identification information; and receiving program information, which is corresponding to the program source identification information and replied by the smart device in response to the watch request message, and providing the program information to the portable device for display. Therefore, according to the embodiments, the same or different program information may be simultaneously viewed on the portable device and the smart device after establishing the connection between the portable device and the smart device through a handshake protocol.
