Abstract

For fiber-to-the-curb program switching, which is done at the central office, the same fixed frequency slot is always used for distributing the TV program selected for a video recording device at the subscriber's premises; for its related display, another selected slot is always used for distributing another selected TV program; the set-top converter is provided with two narrow band filters, one for each dedicated slot, instead of expensive tuners; the same set-top converter can be used in other rooms of the subscriber premises, except using a plug-in tuner for placing additional selected TV programs received from remaining, nondedicated slots into the same filter band used for the TV associated with the video recording device.
