“…This method has the potential for application in the educational environment, because in this scenario all the students in a class play the same video game. Defining the players' area of interest within the scene and the different encoding of scenes detail at macroblocks level is a method by which significant savings can be achieved in the used network traffic, while retaining a high level of the QoE [53]. A similar principle of interest field analysis is used in [54], but by using virtual scene rendering information, which enables acceleration of the video encoding process, especially the calculation of the motion vector and selection of the macroblock mode, which reduces encoding time by as much as 72%.…”

The use of digital games in education has been the subject of research for many years and their usefulness has been confirmed by many studies and research projects. Standardized tests, such as PISA test, show that respondents achieved better reading, math and physics results if they used the computer more for gaming-related activities. It has been proven that the application of video games in education increases student motivation, improves several types of key skillssocial and intellectual skills, reflexes and concentration. Nevertheless, there are several challenges associated with the application of video games in schools and they can be categorized as technical (network and end device limitations), competency (teachers' knowledge in the area), qualitative (lack of educational games of high quality), and financial (high cost of purchasing games and equipment). The novel architecture for delivery of gaming content commonly referred to as "cloud gaming" has the potential to solve most of the present challenges of using games in education. A well-designed cloud gaming platform would enable seamless and simple usage for both students and teachers. While solving most of the present problems, cloud gaming introduces a set of new research challenges which will be discussed in this section.

“…The data storage of wireless sensor network is divided into internal data storage and external application data storage, and the wireless network is made by sensors and sink nodes [7,8]. Through the wireless network communication, a large number of sensor nodes will be deployed within or near a monitoring area and a network can be constituted by self-organization [9,10].…”

Based on the characteristics of data storage structure of HBase, and under the guidance of the storage optimization strategy, an efficient real-time storage model is designed. The real-time flow of data, which has fast storage in the cluster database, will satisfy the user's multiple needs of the data storage performance. Extenics primitives are used to integrate heterogeneous data-sets stored in the HBase database, cross-regional wireless sensor network data, and global data storage management catalogs for a double layer distributed storage architecture to improve storage and access efficiency. Under the circumstances that the storage space is insufficient or the storage space of the cluster text system is too massive, the HBase database cluster dynamic updating and optimizing the database space are also the research direction of this paper. Finally, the article carries on the experiment and concludes the appraisal through simulation.

“…The game information is also used to compute the motion vectors (MVs), which are then exploited in a fast mode selection algorithm to accelerate encoding. In [5], the authors propose a MB level rate control scheme, in the context of H.264 [6], where more bits are allocated to the region of interest (ROI) based on its importance. The same approach, but with a different spatial ROI-based weighting assignment, is proposed in [7] for the H.265 (aka high efficiency video coding (HEVC)) [8] video encoder.…”

Cloud gaming is a rising new trend for remote video gaming. Players send their commands using a thin-client device to a graphics rendering cloud server and receive a compressed video stream in response. However, video games with complex textures and motions, especially at high resolutions, require a substantial bitrate to deliver good visual quality. When the player's Internet connection is constrained or fluctuates, the visual quality may be significantly reduced, which negatively impacts the playing experience. In this paper, we present an Action-awaRe COmbat moDEl (ARCODE) for massively multiplayer online role-playing games (MMORPGs) running on cloud gaming platforms to improve compression efficiency. ARCODE captures different action data for different object types in the battle scene and determines the importance of each object relative to the player in each game state, considering the actions at the time. Based on the significance of each object to the player, the model determines how frequently its position should be updated. Reducing the number of motion updates in the scene leads to fewer bits needed to encode the video frames. Our experimental results on various test cases show that, for similar visual quality as that of the traditional approach, ARCODE can reduce the video bitrate from 9% to over 40%.
