Abstract (en)
[origin: WO0022822A1] A cable television system (100) includes a transmitter (105) for transmitting a forward signal including a first signal having information within a first frequency range and a second signal having baseband data transmitted in a second frequency range. A node (120) receives the forward signal and splits the first signal from the second signal, and a data processing hub (255), such as an Ethernet hub, processes the second signal to arrange the baseband data into data packets. Subsequently, the first and second signals are recombined as a forward signal that is further transmitted within the cable television system (100). At least one tap (125) is included in the system (100) for splitting off a portion of the forward signal to provide the information and the baseband data at subscriber ports (336) of the tap (125).
