Abstract: A system for preventing faulty connection between PoC and PoE. The system includes a signal generating circuit for generating a detection signal of a detection format of a powered device. A signal feedback circuit is configured to receive the detection signal, and to send a feedback signal to a power source equipment. A signal detecting circuit is configured to detect the feedback signal. A first control switch is coupled to the signal detecting circuit. A second control switch is coupled to the signal feedback circuit.

Abstract: An image processing apparatus is disclosed. The splitter duplicates an original image signal into a first image signal and a second image signal. The first signal converter converts the second image signal having a first image format to the second image signal having a second image format. The image processor stores the second image signal in the memory according to an enable signal and continuously compares whether the current frame of the second image signal is the same as the previous frame of the second image signal. If they are different, the image processor continuously receives the second image signal and stores it in the memory. If they are the same, the image processor stops receiving the second image signal. The second converter converts the second image signal having the second image format to the second image signal having the first image format.
