Abstract
Abstract A display and control module sends synchronization signals and camera display codes to a loop multiplexer module and a home run multiplexer module. The loop multiplexer module has a plurality of cameras coupled to a loop multiplexer unit. The loop multiplexer unit controls the synchronization and selection of video from the cameras for sending to the display and control module. The home run multiplexer includes a home run multiplexer unit coupled to a plurality of coaxial cables, each coaxial cable having at least one video camera thereon. The home run multiplexer unit receives the synchronization and control signals from the display and control module and uses those signals for synchronizing and selecting video images from one of the plurality of cameras for sending to the display and control module. The display and control module uses the video signals from the loop multiplexer module and the home run multiplexer module to display on a display.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
A system for the control of video signal multiplexing, said system comprising: a slave module having a plurality of cameras coupled to a slave control unit for obtaining video signals from one of said plurality of cameras for output therefrom; a master control module having a monitor and a master control unit for receiving the video signals from the slave control unit and transmitting the video signals to said monitor and for sending a camera selection signal to said slave control unit that corresponds to one of said plurality of cameras; and wherein said slave control unit determines which one of said plurality of cameras to obtain the video signals from by selecting in a predetermined order one of said plurality of cameras for output from a list of said plurality of cameras and obtaining the video signals from the selected one of said plurality of cameras for output until said master control unit sends the camera selection signal to said slave control unit whereupon said slave control unit obtains the video signals from the camera corresponding to the camera selection signal.
Claim 2
Independent Claim
182 words
A system for the control of video signal multiplexing, said system comprising: a slave module having a plurality of cameras coupled to a slave control unit for obtaining video signals from one of said plurality of cameras for output therefrom; a master control module having a monitor and a master control unit for receiving the video signals from the slave control unit and transmitting the video signals to said monitor and for sending a camera selection signal to said slave control unit that corresponds to one of said plurality of cameras; and wherein said slave control unit determines which one of said plurality of cameras to obtain the video signals from by selecting in a predetermined order one of said plurality of cameras for output from a list of said plurality of cameras and obtaining the video signals from the selected one of said plurality of cameras for output until said master control unit sends the camera selection signal to said slave control unit whereupon said slave control unit obtains the video signals from the camera corresponding to the camera selection signal.
Claim 3
Dependent Claim
104 words
The system of claim 1, wherein each of said plurality of cameras in said slave module are associated with a different camera code and transmits a video signal upon receiving the associated camera code; and wherein said slave control unit obtains said video signals from said plurality of cameras by transmitting the camera code associated with a particular one of said plurality of cameras that the video signals are to be obtained from to said plurality of cameras, and receiving the video signals from the particular one of said plurality of cameras that the video signals are to be obtained from in response thereto.
Claim 4
Dependent Claim
75 words
The system of claim 2, wherein said plurality of cameras are connected to a loop of cable having a first end and a second end, and wherein said slave control unit inserts the camera code onto the first end of said loop of cable for transmission to said plurality of cameras, and wherein said slave control unit receives the video signals from said plurality of cameras at the second end of said loop of cable.
Claim 5
Dependent Claim
13 words
The system of claim 1, wherein said slave module is a loop module.
Claim 6
Dependent Claim
14 words
The system of claim 1, wherein said slave module is a home run module.
Claim 7
Dependent Claim
31 words
The system of claim 1, wherein said slave control unit transmits a slave synchronization signal to said plurality of cameras and said plurality of cameras synchronize to said slave synchronization signal.
Claim 8
Dependent Claim
35 words
The system of claim 6, wherein said master control unit transmits a master synchronization signal to said slave control unit and said slave control unit synchronizes said slave synchronization signal to said master synchronization signal.
