Abstract A method for multiplexing tuner in bidirectional cable TV system is disclosed. The DOCSIS standard is used as transmit data in said TV system. A set top box is used to selectively receive TV programs in some channel by tuner. By extending the DOCSIS standard, the number of up channel is modified as the number of down channel to make terminal change the down channel of signals. As a result, the set top box with only one tuner can be used to selectively receive TV programs and provide interactive data service.
