Research on the Evaluation of Audiovisual Information Dissemination Effect Based on SIR Model : —Take TV Program Communication as an Example

In order to evaluate the complex propagation effect and influence of audio-visual information across screen and multiple terminals in the environment of media. Establishing a TBSIR model based on the principle of complex network SIR model, improving the original CCTV program evaluation index system to obtain the program propagation effect index to determine the initial parameter propagation rate λ and immune probability μ of the model. Selecting three CCTV-3 television programs to perform simulation calculations and obtain a TV program transmission effect map. From the map, which the time required for TV program transmission and the proportion of the audience covered by the program can be used to obtain the transmission effect and influence of the three programs.
