For NTSC format, the Chroma standard level is 40 IRE
If the Chroma level is low or too low, the color will not bright, and some details on the iamge will lost
or get dark or white when the monitor receives the iamge.
If the Chroma level is too high, there will be spots on the image. If this occurs, it cannot get the clear
image with all the details.
If the coaxial cable is too long, it will reduce the chroma level
2.3.8 PTZ controller
Display the input video images. Pan/tilt the P/T unit and zoom in/ out the image. Setup the controlling
parameters like protocol, communication port, baud rate, PTZ ID, pan/tilt speed; set and call preset
position.
2.3.9 Enhanced Color bar generator
The tester sends out the color bar by its BNC output to the monitor at the monitoring center. If the
monitor receive the color bar, it means the video transmit channel works normally. Meanwhile on the
basis of the received color bar, the monitoring center can judge if transmission has loss or interference.
The tester can also send out the color bar by its BNC output, then receive and display the color bar by
its BNC input to test on-site video transmission, such as video optical transmitter and receiver, video
cables.
The new function of sending the testing image can judge if the monitor receives the image well.
The new color bar (red, green, blue, white, black) can test the monitor whether have white or black dot
etc.
