碩士 === 國立臺灣科技大學 === 資訊管理系 === 105 === Technology advances have changed many things like multimedia storage and streaming video from local servers to cloud servers. After smart phones have become popular, people can use their phones to watch videoes. However, the network transfer service from the cloud is not unlimited, as it depends on how much you pay (Pay as You Go). Also, the mobile network transfer and speed are also limited. All of these make client users and service providers spend money to increase network transfer efficiency. Thus, to solve the aforementioned problems, we did some study, and we proposed a system that can change video quality depending on luminance and decrease the network transfer usage accordingly. Finally, we developed a system with the server application and the client application based on our proposed method. We collected user's feedback based on their current luminance, and generated a video with their feedback and the luminance. The users couldn't tell the difference between the original video and the adjusted one easily. As a result, we proved our methods, can help to reduce the amount of data transfer.
