1. A method for identifying video signal source, comprising:
combining a first video data and a first identification image corresponding to a first identification code as a first combined video data by a first transmitter control unit of a first transmitter device;
transmitting the first combined video data to a receiver control unit of a receiver device by the first transmitter device; and
outputting the first combined video data to a display device by the receiver control unit of the receiver device;
combining a second video data and a second identification image corresponding to a second identification code as a second combined video data by a second transmitter control unit of a second transmitter device, combining the first combined video data and the second combined video data as a split screen video data and outputting the split screen video data to the display device by the receiver control unit of the receiver device;
wherein the source of the first video data is an information processing device, and the first identification code is a network IP address of the information processing device, a hardware serial number after manufacture of the first transmitter device, or a obtained user's personal information when the information processing device executes a communication software;
wherein the first video data corresponds to a first video region on a display screen of the display device, the second video data corresponds to a second video region on the display screen of the display device, a user operation position is provided by a user input device;
wherein whether the user operation position is located in the first video region is determined by the receiver control unit, when it is determined that the user operation position is located in the first video region, the receiver control unit sends a first prompt instruction to the first transmitter device, a first indication device of the first transmitter device emits a first light or a first sound;
wherein whether the user operation position is located in the second video region is determined by the receiver control unit, when it is determined that the user operation position is located in the second video region, the receiver control unit sends a second prompt instruction to the second transmitter device, a second indication device of the second transmitter device emits a second light or a second sound, the first light and the second light are different, and the first sound and the second sound are different, the first video region and the second video region are shown in the form of split screen.
