ABSTRACT:
The cable television digital audio system of the present invention provides seamless reception and integration of analog video and audio programs and digital audio programs. The system comprises a settop terminal with a digital audio module for receiving an RF modulated digital data stream. The settop terminal permits the simultaneous reception of analog video and audio broadcasts and digital audio broadcasts. The digital audio module may include a separate frequency agile RF tuner enabling both the settop terminal and digital audio module to be tuned to and reproduce separate programs. A television monitor receiver displays normal video programming from the settop terminal and also provides on-screen display (OSD) of channel selection and program information.
