"With the rapid development of the Internet, cloud gaming has increasingly gained attention. Cloud gaming is a new type of cloud service that allows a game to run on the cloud servers, and players interact with the game remotely on their own light-weight clients. There are many potential benefits for both players and game developers to deploy a game on a cloud server, such as reducing the need for clients to update the game, easing development of cross-device games and helping prevent software piracy. In this work, I developed a cloud game engine, Drizzle, with a time warp algorithm for latency compensation, and implemented a new transmission method that reduces the network bandwidth. Using Drizzle, I also developed a simple cloud game to evaluate the functionality and performance. Experiments with this game in a controlled laboratory environment provide objective measurements of game performance and subjective measurements of user performance. Analysis of the results shows Drizzle with time warp did not reduce noticeable latency but helped players get higher game scores compared to Drizzle without time warp. Moreover, Drizzle reduced network bitrates compared to some conventional cloud transmission methods."

Football fans do not have the time to watch every game in its entirety and need an effective solution that summarizes them the story of the game. Human-generated summaries are often too short, requiring time and resources to create. We utilize the advantages of Interactive TV to create an automatic football summarization service that is cohesive, provides context, covers the necessary plays, and is concise. First, we construct a degree of interest function that ranks each play based on detailed, play-by-play game events as well as viewing statistics collected from an interactive viewing environment. This allows us to select the plays that are important to the game as well as those that are interesting to the viewer. Second, we create a visual transition that shows the progress of the ball whenever plays are skipped, allowing the viewer to understand the context of each play within the summary. Third, we enable interactive controls that allow viewers to manipulate the summary and delve deeper into the actual game whenever they wish. We validate our solution through two user studies—one to ensure that our degree of interest function selects the plays that are most interesting to the viewer, and the other to show that our transitions and interactive controls provide a better understanding of the game. We conclude that our summary solution is effective at conveying the story of a football game.
