Multi-component video system controller

In a system having a single television receiver capable of receiving transmitted video signals in a plurality of broadcast bands, a source of external video signals and a video signal recorder for recording video signals thereon, a controller for the selective display on said television receiver of said transmitted, external or recorded video signals and the selective recording on said video signal recorder of said transmitted or external video signals, said controller comprising:

• a first plurality of user selectable control means for providing first control signals for the selective display on said television receiver of said transmitted, external or recorded video signals;
• a second plurality of user selectable control means for providing second control signals for the selective recording on said video signal recorder of said transmitted or external video signals;
• a plurality of input terminals for receiving said transmitted, external and recorded video signals;
• a plurality of output terminals for providing said transmitted, external or recorded video signals to said television receiver for display thereon and for providing said transmitted or external video signals to said video recorder for recording thereon;
• and
• a first logic circuit coupling each input terminal to said first plurality of user selectable control means and to an output terminal connected to said television receiver and responsive to said first control signals received from said first plurality of user selectable control means and a second logic circuit coupling each input terminal to said second plurality of user selectable control means and to an output terminal connected to said video signal recorder and responsive to said second control signals received from said second plurality of user selectable control means, wherein said first and second logic circuits include respective portions coupled to the same input terminal and wherein said respective portions of said first and second logic circuits are rendered in opposite conducting states when said video signals provided to said input terminal are displayed on said television receiver or recorded on said video signal recorder, and wherein a portion of said first logic circuit coupling the video signal recorder input terminal to said television receiver is rendered conducting when corresponding control means are selected in said first and second pluralities of user selectable control means such that a video signal simultaneously displayed and recorded is provided to said television receiver by said video signal recorder for display thereon in eliminating video signal losses due to signal splitting.

In a system having a single television receiver capable of receiving transmitted video signals in a plurality of broadcast bands, a source of external video signals and a video signal recorder for recording video signals thereon, a controller for the selective display on said television receiver of said transmitted, external or recorded video signals and the selective recording on said video signal recorder of said transmitted or external video signals, said controller comprising:

• a first plurality of two position mechanical switches for providing first control signals for the selective display on said television receiver of said transmitted, external or recorded video signals;
• a second plurality of two position mechanical switches for providing second control signals for the selective recording on said video signal recorder of said transmitted or external video signals wherein the selection of one switch in one of said first and second pluralities of switches automatically de-selects the other switches in said one plurality of switches;
• a plurality of input terminals for receiving said transmitted, external and recorded video signals;
• a plurality of output terminals for providing said transmitted, external or recorded video signals to said television receiver for display thereon and for providing said transmitted or external video signals to said video recorder for recording thereon;
• and
• first and second pluralities of electronic control devices coupled respectively to said first and second pluralities of mechanical switches for connecting each input terminal to an output terminal connected to said television receiver and to an output terminal connected to said video signal recorder, respectively, in response to control signals received from said first and second plurality of mechanical switches, wherein corresponding first and second electronic control devices coupled to the same input terminal are rendered in opposite conducting states by means of said control signals when the video signals provided to said input terminal are displayed on said television receiver or recorded on said video signal recorder, with the one of said first plurality of electronic control devices coupling said video signal recorder to said television receiver rendered conducting when corresponding switches are selected in said first and second pluralities of mechanical switches such that a video signal simultaneously displayed and recorded is provided to said television receiver by said video signal recorder for display thereon in eliminating video signal losses due to signal splitting.

A system for selectively providing a first video signal or first and second video signals respectively to a television receiver and a video signal recorder, said system comprising:

• a plurality of input terminals for receiving said video signals;
• first and second output terminals respectively coupled to said television receiver and to said signal recorder;
• user selectable control means for generating control signals;
• logic means coupled to said control means and responsive to said control signals;
• and
• first and second pluralities of conductive elements wherein each of said first plurality of conductive elements couples an input terminal to said first output terminal and each of said second plurality of conductive elements couples an input terminal to said second output terminal with each of said conductive elements operatively coupled to said logic means and wherein respective conductive elements connected to the same input terminal to which said video signals are provided are rendered in opposite conducting states in response to said control signals and wherein one of said first plurality of conductive elements couples said signal recorder to said television receiver for providing a video signal thereto for the simultaneous recording and display thereof in eliminating video signal losses due to signal splitting.
