Abstract

A system is presented for the multipath reception of video signals, including sound an/or image signals. The system includes at least two receivers and a diversity unit. At least one receiver receives and processes analog video signals, while the one or more remaining receivers receive and process digital video signals. The system may further include an analog selector unit for selecting the highest quality analog signal, and/or a digital selector unit for selecting the highest quality digital signal. The diversity unit receives the processed analog and digital video signals and combines them to produce a resulting video signal having a quality at least as high as the better of the processed analog and digital video signals. The diversity unit may combine the received video signals by performing a weighted addition of the signals.
