### Simulation Results and Discussion  
In this section, the MATLAB simulation is based on the proposed live broadcast traffic model to analyze the results. The simulation sets the average file size of the DASH dataset to the minimum service bit rate and the maximum file size of the DASH dataset to the maximum service \begin{table}

The same results can be confirmed for the rest of the media. In contrast, when transmitting at the maximum bit rate, the minimum delay time is satisfied, but the B/W efficiency deteriorates. The same results are confirmed for the rest of the media. Figure 7 reveals a pattern similar to the results of Figures 4-6, but Figures 8-10 indicate that the maximum total delay, which seriously affects the service, is not high even at the minimum service bit rate. The reason is that 'Dashevc-live-4K V11' did not use rate control technology when encoding, and the other media did use the rate control technology when encoding. Rate control technology compresses media at a target bit rate as much as possible, so it can reduce the standard deviation of the segment files and the transmission delay. However, the media quality is relatively poor. Therefore, the encoding should be performed in consideration of the media quality when using the rate control technology. The simulation results of this paper reveal the B/W efficiency and transmission delay outcomes in media transmission. However, the results do not include the protocol overhead.
