Multimedia technology is often associated with computers, and the digital and interactive processing capabilities of computers have greatly promoted the development of multimedia technology. Generally speaking, multimedia can be regarded as a new technology or product formed by combining advanced computer technology with video, audio and communication technology. Therefore, we think that multimedia is the comprehensive processing of multimedia information such as text, graphics, images, audio and video by computer, which makes all kinds of information logically related and integrated into a system and interactive.

The publication and dissemination of information refers to the transmission process of information from sender to receiver, which has three basic elements: sender, receiver and communication channel. From the communication channels, there are two ways-one-way and two-way. One-way communication means that the sender simply sends and delivers information regardless of whether the receiver receives or has feedback. Two-way communication means that the feedback from the receiver will be passed on to the receiver, and the two sides will interact and influence each other. As an information dissemination system, it has high-tech features such as multimedia and cloud computing. From the communication point of view, this system should be a two-way communication network as a communication channel.
