AN APPARATUS AND METHOD IS DESCRIBED FOR TRANSMITTING, RECEIVING AND COMMUNICATING PROGRAM DATA SIGNALS WHICH ARE COMBINED WITH DIGITAL DATA SIGNALS. PREFERABLY, THE PRESENT INVENTION COMPRESSES 30 DIGITAL AUDIO SIGNALS (10-1 THROUGH 10-30), MULTIPLEXES THEM WITH TITLE, TRACK, ARTIST, RECORD LABEL, YEAR, ETC., PROGRAM INFORMATION (20-1 THROUGH 20-30 AND 30-1 THROUGH 30-30), AND TRANSMIT THE COMBINED SIGNALS VIA SATELLITE (50) TO A RECEIVING STATION (60). THE RECEIVING STATION DEMULTIPLEXES (70) THE SIGNALS AND SENDS THEM VIA A CABLE DISTRIBUTION SYSTEM TO A SUBCRIBER''S DIGITAL MUSIC TUNER (100). THIS TUNER FURTHER DEMULTIPLEXES (143) AND DECODES (147) THE SIGNALS SO THAT THE DIGITAL AUDIO SIGNALS MAY BE CONVERTED TO ANALOG (160) AND OUTPUT FOR LISTENING, WHILE THE CORRESPONDING DATA SIGNALS ARE COMMUNICATED (180) TO THE SUBSCRIBER. IN AN ALTERNATIVE PREFERRED EMBODIMENT, THE PROGRAM DATA SIGNALS ARE TRANSMITTED TO A REMOTE CONTROL RECEIVER (200). WHERE THEY ARE DISPLAYED. THE SYSTEM DESCRIBED IN THE PRESENT INVENTION MAY BE USED FOR TRANSMITTING VIDEO, SOFTWARE OR GAMES WITH PROGRAMS DATA TO SUBSCRIBERS.(FIG. 1) |
