Claim 3
Dependent Claim
30 words
The apparatus of claim 1 further comprising external input program source selection switches connected to the multi-channel tuner for selecting input program sources as controlled by a remote subcarrier signal.
Claim 4
Dependent Claim
28 words
The apparatus of claim 2 further comprising internal program source selection switches connected to the multi-channel tuner for controlling interconnections between the multi-channel tuner and other user terminals.
Claim 5
Dependent Claim
46 words
The apparatus of claim 1 further comprising switching means in the switching control center external of the remote switching and processing converter and connected to the cables for switching signals from the user terminal to other remote switching and processing converters in the switching control center.
Claim 6
Dependent Claim
108 words
The apparatus of claim 1 further comprising an office terminal connected to the remote switching and processing converter by a cable and a directional coupler and a dual channel filter capable of receiving standard television or HDTV signals from the remote switching and processing converter and for having connected thereto means for creating signals for sending to the switching control center and having carrier signal means connected thereto and having subcarrier signal means connected to the carrier signal means for providing first and second subcarrier signals to control the switching of the remotely controlled multi-channel tuner in the remote switching and processing converter with the first subcarrier channel.
Claim 7
Dependent Claim
37 words
The apparatus of claim 5 in which the second subcarrier signal means controls switching means in the switching control center external to the remote switching and processing converter for controlling the provision of signals to the tuner.
Claim 8
Dependent Claim
39 words
The apparatus of claim 5 wherein the second subcarrier signal is provided with means in the switching control center external to the remote switching and processing converter for controlling the switching of the return signal from the user terminal.
Claim 9
Dependent Claim
84 words
The apparatus of claim 5 wherein the second subcarrier controls external switching in the switching control center to connect the tuner to a source of facsimile signals and wherein the dual channel filter in the user terminal is connected to a converter which is in turn connected to a VCR and display and which is connected to a computer and to a printer for printing facsimilies from the channel provided to the tuner according to the control of the first and second subcarrier signals.
Claim 10
Dependent Claim
37 words
The apparatus of claim 1 whereby internal modules of the remote switching and processing converter can encompass bandwidths of 12 MHz so as to enable the tuning, processing, modulation and amplification of high definition television signals (HDTV).
