Abstract: In recent years,the emergence of 4G and 5G network has greatly improved the bandwidth of mobile device data transmission,while the performance of video playback devices has been also improved,which increases the user’s demand on the quality of video streaming gradually.Thus,improving the profit of video streaming over mobile network is becoming more and more important.This paper analyzed the effect of user preference on the profit of multi-content videostreaming system.Moreover,this paper proposed the profit model of End Users based on user preference by consi-dering the traffic cost and formulated the optimization problem of total system profit into weighted profit optimization problem.Considering that the users with different preferences have different effects on the total profit of video streaming system,this paper proposed a weight selection algorithm of End Users based on preference-bitrate ratio to select the optimal weights under the condition of current user preferences.Then the optimal bitrate under the condition of current user preference was obtained by solving the optimization problem of optimal weighted profit of End Users.The experimental results show that the proposed method improves the total profit of system by 5%~10% compared with the exis-ting method.

Key words: Multi-content, Preference-bitrate ratio, Profit, Traffic cost, User preference, Video transmission
