Abstract

A video system controller (200) inserts synchronization pulses in a video camera line (100), which creates a video frame in the video camera line. The video system driver also inserts a camera code in the active video period of an unseen line of the video frame. A plurality of camera units (301-304) are connected to the video camera line and use the synchronization pulses placed in the video camera line to remain synchronized with the other camera units. When detecting a particular camera code in the video camera line, the camera unit corresponding to the particular camera code inserts a video image signal in the active video time period of the video line for the picture of video that contains the particular camera code. The video camera code returns the video system driver that receives the video frame that contains a composite of the synchronization inputs from the video system driver and the video image signal. The video system controller then transmits a video image signal to a video recorder or video display device (40).

A video output 213 of the video system controller 200 sends video image signals from the video system controller from the video system controller 200 to the video recorder or device. of video viewer 400. In one embodiment of the present invention, video frames 500 are made from several video lines, including unseen video lines 510 and video view lines 520. Each of the video lines 510 and 520 in a video frame 500 further includes synchronization time periods 511 and 521, respectively, and active video time periods 512 and 522, respectively. The video system controller 200 partially creates video frames 500 in the video camera line 100 by inserting sync pulses 530 in the video camera line 100 in the timing periods of synchronization signal 511 and 521. the video lines 510 and 420 for the video frames 500. In one embodiment, the video synchronization pulses 530 generated by the system video controller 200 are standard video synchronization pulses with the appropriate current to provide the amplitude from standard video synchronization pulse to line 100 of video pitcher. During active periods of video time 512 on 510 video lines normally not seen from 500 video frame, the video system controller 200 also inserts camera codes 540 into line 3 of video camera 100. In one embodiment, the camera codes 540 comply with standard video amplitudes. The video synchronization pulses 530 inserted in the video camera line 100 by the video system controller 200 are employed by the video camera units 301, 302, 303 and 304 to remain synchronized within the multi-iplexor system. of video 10. Each of the video camera units 301, 302, 303 and 304 generates a video image signal 550 during the active period of video time 521 of the video lines viewed 520 for the video frames 500 The camera code 540 inserted in the video camera line 100 by the video system controller 200 will correspond to one of the video camera units 301, 302, 302 and 304. When detecting a camera code 540 in the line of video camera 100, the corresponding camera unit 301, 302, 303 or 304 will insert the video image signal 550 generated by the camera unit in the line of video camera 100 in the period of video tie active 522 of video line vi 520 for video frame 500. Insertion of video signal 550 into video camera line 100 will add ideo 550 image signal to synchronization pulse 530 in the video view line 520, which results in a video frame 500 having a video view line 520 with a composite of the synchronization pulse 530 in the synchronization time period 521 and the video image signal 550 in the active 522 period of video time. The video system controller continues the video frame 500 which contains the compound of the sync pulse 530 and the video image signal 550, at the input 212. Upon receiving the video frame 500 which contains the sync pulse compound 530 and of the video image signal 550, the video system controller 200 sends the appropriate video image signal through the video output 213 to the video recorder or video display device 400.

In a "blocked line" condition the units of ara 301, 302, 303 and 304 take video images in the same cycle location for each of the input energy cycles. Other electrical devices that use the same electrical input power will be. " n in the same site location for each of the => cycles of input energy when the urudade-. of cameras 301, 302, 303, and 304, in a condition of "blocked lines" take video images.

The on-off control 220 also generates the camera codes 540 which control which of the camera units 301, 302, 303 or 304 is active during each video frame 500. The determination of the sequence of the active camera units, or that a camera is displayed or recorded, it is determined by the timing control 220. the decision as to which video camera unit is being used can be based on a tight synchronization mode for alarms onitoring , or other conditions that may require the change of the camera's ultiplexion. Accordingly, the control synchronizes ion 220 with the action of mu 11 iplex ion of the multipole system < or video 10 determining which camera unit 301, 302, 303 or 304 is active during each video frame 500, and controls the operation of the entire system uit iplexsr video 10 based on a logic designed spe íficamente for desired application. The video synchronization and camera code inserter 230 and the current driver 240 convert the synchronization pulses 530 and the camera codes 540 into a current mode and insert them into the appropriate video lines 510, 520 of the control box. video 500 on the video cable 100 through the output 211. The video frame 500 having the sync pulse compound 530 of the video system controller 200 and the video image signal 550 from one of the camera units 301, 302, 303, or 304, returns in video camera line 100 to video system controller 200 through input 212.

In one embodiment, the regulator 270 has a gain of two. The termination resistors 250 and 260 are connected to the first end 110 and the second end 120 of the video camera line 100., respectively, through the output 211 and input 212, respectively, of the video system controller 200. The termination resistors 250 and 260 help to avoid reflection in the line of the video camera 100. In a embodiment, the video camera units 301, 302, 303, or 304, are of the type of camera unit 600 which uses a standard camera 640. In the camera unit 600, the video frames 500 which are inserted in the line of video camera 100 by the monitor 200 of video system are received by a separator 630. The separator 610 allows synchronization pulses 530 and camera codes 540 placed in the line of video camera 100 by the controller of video system 200 are recorded in a video synchronization separator 620 and a camera code decoder 630 of the camera unit 600 without affecting the video frame 500 in the video camera line 100. The synchronization separator of v ideo 620 reads the non-snoring pulses 530 from the video input boxes 500 and sends these sync uses 530 to a standard 640 camera and a 650 video sync remover.

The standard camera 640 employs the 530 synchoni-ion pulses to remain un-snoring with the other camera units and components of the video multiplexer system 10. A generator 64? The synchronization signal in the standard camera 640 receives the synchronization signals 530 from the video indexing separator 620 and generates a synchronization signal based on the synchronization pulse 530 in the video frames 500. In one embodiment, the video synchronization 620 is a video synchronization separator model EL4583C, manufactured by élantec in Milpitas, California. The synchronization signal (s) generated < s > by the synchronization generator 642 is supplied < n) to a clock driver 644 and a video processor 648. The clock driver 644 drives an image forming device (CCD) 646 to create an image that is sent to the 648 video processor. The 648 video processor sends a video output signal having a camera sync signal there to the video sync remover 650. The video sync remover 630 removes the out-of-band signals normally generated by the standard 640 camera by erasing the sync signals from video (both vertical and horizontal) of the video signal that the standard camera 640 is sending. Accordingly, the video line 520 of the video frame 500 which is sent by the video sync remover 650 will have only the signals of video image 5 in the active time period 522. A 660 current driver converts d- = video signals from the video synchronization remover 65 0 in a current signal supplied to an enabling switch 670. The camera code decoder 630 reads the camera code 540 from the video frame 500 supplied to the camera code decoder 630 by the separator 610. In In one embodiment, the camera code decoder 630 is a logical device such as a microcontroller, a programmable logic device, or a specific integrated circuit for application (ASIÓ. If the camera code has inserted into the video camera line 100 by the video system controller 200 corresponds to the camera unit having the camera code decoder 630, then the camera code decoder 630 transmits a enabling signal to enabling switch 670. Upon receiving an enabling signal from the camera code decoder 630, the home switch 670 connects the current driver 660 to the video camera line 100, thereby inserting the video signal signals of the camera. video from the current driver 660 in the video camera line 100. In one embodiment, upon receipt of a camera code 540 associated with the part-camera unit, the camera code decoder 630 sends the signal enabling the switch 1111 to 670 and continues to send the enabling signal to the enabling switch 670 until the camera code decoder 630 receives a code of camera 540 not associated with the particular camera unit. A person with certain knowledge in the art will recognize that other methods can be used to insert the video signals in the ce.txv3 line. ra 100, such as by sending by the camera code decoder 630 a start and stop enabling signal to the enabling switch 670, the enabling switch 670 remaining connected between the current driver 660 and the video camera line 100 for a video frame upon receipt of a trigger enabling signal from the camera code decoder 630, the enabling switch 670 being activated in the absence of an enabling signal from the camera code decoder 630, or the like. Accordingly, when the camera code '540 in a video frame 500 in the video camera line 100 or corresponds to the camera code required for a specific unit of the camera units 600, the specific camera unit 60 will not insert a video image signal 550 into the ideo camera line 100.

In one embodiment, the video synchronization separator 720 is a separator. s ncroni a ion de video model EL4583C, manufactured by élantec en t ilpitas, California. The modified camera 740 differs from the standard camera 640 insofar as the output signal from the modified camera 740 does not have a synchronization signal. A current driver 760 converts a video signal from the modified camera 740 into a current signal and supplies this current signal to the enabling switch 770. The camera code decoding 730 reads the camera code 540 from the frame 500 video to the camera code decoder 730 by the controller 710. If the camera code inserted in the video camera line 100 by the video system controller 200 corresponds to the camera unit having the camera decoder 730 , then the camera code decoder 730 transmits an enabling signal to the enabling switch 770. Upon receiving an enabling signal from the camera code decoder 730, the enabling switch 770 inserts the video image signals from the impeller of current 760 in the video camera line 100. In one embodiment, upon receipt of a 540 camera code associated with a unit of particular camera, the camera code decoder 730 sends the enabling signal to the enabling switch 770 and continues to send the enabling signal to the enabling switch 770 until the camera code decoder 730 receives a camera code 540 not associated with the particular camera unit. A person with certain knowledge in the art will recognize that other methods for the insertion of video signals into the line of video camera 1O0, co or for example the camera code decoder 730 that sends a start and stop enabling signal to the camera. enabling switch 770, enabling switch 770 remains with state between current drive 760; > the video camera line 100 for a video frame upon receipt of a trigger enabling signal from the camera code decoder 730, the enabling switch 770 being activated in the absence of an enabling signal from the camera code decoder. 730, or similar. Accordingly, when the camera code 540 in a video frame 500 in the video camera line 100 does not correspond to the camera code required for a specific unit of the camera units 700, the specific camera unit 700 does not inserts a video image signal 550 into the video camera line 100.
