APPROACH TO DETERMINING THE SIZE OF MULTIMEDIA APPLICATIONS DATA BUFFER BASED ON VARIABLE CONNECTION BAND WIDTH
240 KB
This paper describes a dynamic way to determine the size of the data buffer in the media application. We have created a system to determine theoreticalapplication’s buffer size value. This system is composed of the network filter and traffic analyzer, as well as its own client-server application written in high-level language Java, emulating video streaming process from the server to the client. The study received the best size of the data buffer in volatile bandwidth data transfer. Under the best size, we mean the size of the data buffer that allows you to download the video part from the server quickly, and thus is sufficient to avoid any gaps in the playback video. The formula for determining the buffer size was compiled, based on the analysis of the data, received by ourexperiments. This formula allows buffer to have the exact size for uninterruptable video playback. There was further investigation of this formula to determine minimum video stream playing time, which would be enough for further approximation of the size of the input data buffer. In conclusion, we analyzed YouTube application buffer size. This investigation showed that the application does not account for changes in the speed of the client connection.
