Abstract
A system and method for providing interactive multimedia services to subscriber premises utilizing in whole or in part the public switched telephone network. The service is provided using an existing twisted wire pair subscriber line with Asymmetrical Digital Subscriber Line (ADSL) technology. The ADSL connection provides a 1.5 mbits/s downstream video information channel, a two-way telephone connection, and a 16 kbits/s control channel. This multiplexed signal is then separated and processed on premise and distributed in a two-way fashion as a complex radio frequency signal. Multiple television sets and telephone stations may be simultaneously served and may conversely communicate commands upstream to the multimedia network. A complete installation may be made in an entire premise without the necessity for any significant installation of new wiring. The system and methodology provide flexibility and are adapted to serve as an integral termination for multiple multimedia distribution and delivery architectures.
