Abstract: The present invention disclosed a system and method for transmitting multi-channel signals. With this system and method, each user can watch all available DTV channels without an exclusive antenna and tuner. The UDP port numbers are applied as the virtual channels to be selected by users, and decreasing the number of required antennas and tuners also decrease cost. The system comprises a plurality of audio/video sources for providing audio/video content and a server. A hub is coupled to the server, and a plurality of display units is coupled to the hub, whereas each of the display units receives the audio/video signals and displays the audio/video content from at least one of the audio/video sources.
