Abstract(in English) As networks become more sophisticated, there is growing interest in cloud gaming, a service that allows users to play games running on a server remotely over a network. By using cloud gaming systems, users can play games that require high performance processing power on terminals with limited processing power. However, when playing games through a cloud gaming system, the response delay affects the quality of the experience. In order to provide users with an experience as if they were playing a local game on a cloud gaming system, it is necessary to reduce the response delay, including processing delay, transmission delay, and propagation delay, to the utmost limit. In this paper, we propose a speculative video transmission method for reducing the response delay in a cloud gaming system, and conduct a basic evaluation of the method. In this paper, we propose a speculative video transmission method to reduce the response delay in a cloud gaming system, and conduct a basic evaluation of the proposed method. In the proposed method, the cloud gaming server estimates the next input from the user and encodes the corresponding game video in advance. In this paper, we propose a speculative video processing method that estimates the next input from the user and encodes the corresponding game video in advance. The proposed method aims to reduce the response delay without straining the communication bandwidth by immediately sending the game video that corresponds to the actual input from the user. In order to evaluate the reduction of the response delay by the proposed method, we experimentally evaluated the encoding delay for the actual game video.
