Abstract
Analog video signals are communicated from multiple service providers to subscribers by using analog optical carriers. Unlike digital optical carriers that typically support data services or IP TV, analog optical carriers that can be demodulated or translated back into the analog radio-frequency (RF) signals do not require additional and costly hardware for reception by a RF receiving device such as a television (TV) set. With the present invention, a TV set does not need significant digital hardware such as a digital set top box to allow the TV set to view video signals from a desired service provider. The present invention can allow a plurality of competing service providers to offer video services to a subscriber through a single optical network.
