Abstract
A multiple input data receiver for bi-directional cable television (CATV) systems simultaneously monitors and selectively receives a return path signal on a plurality of return paths. When an appropriate data or signal transmission is detected on a return path, the corresponding return path is selected and then demodulated. The demodulated signal is appropriately decoded to yield signal data. Various tests and analyzing may be performed on the signal data. Simultaneous monitoring/receiving of all or a plurality of return paths minimizes system response time.
