The difference between audio and video is that audio corresponds to sound, and video corresponds to image. In a projector, audio corresponds to an audio interface, which is responsible for inputting audio signals to the projector; and video corresponds to a video interface, which is responsible for inputting video signals to the projector.

The difference between audio and video is that audio corresponds to sound, and video corresponds to image. In a projector, audio corresponds to an audio interface, which is responsible for inputting audio signals to the projection; and video corresponds to a video interface, which is responsible for inputting video signals to the projection. The combination of the two together is the AV interface commonly known as everyone. Professionally speaking, it is the RCA interface. It is composed of yellow, white, and red colors. The yellow line is the video transmission line, and the white and red are responsible for the left and right channels. Voice transmission.
Extended information
Since entering the era of high-definition, the usage rate of the AV interface has been greatly reduced. As a general-purpose interface, the AV interface is the standard interface of many non-high-definition devices. In non-high-definition playback devices (such as TV set-top boxes, MP4 players, etc.), the projector can be easily connected through this interface, the projector can be used to watch TV, or use MP4 instead of PC as the playback device, eliminating the need to connect to the computer trouble. However, when playing high-definition content, the AV interface cannot meet the needs of users.
