《云游戏的未来展望》:过去云游戏的挑战在于多媒体传输所需的高带宽以及游戏中的网络延迟。在Proceedings ofthe IEEE最新一期文章中学者们提出了对云游戏未来进展的预测。
In the late 2000s, several startups including OnLive [7] and GaiKai [8]started to offer cloud gaming services. Cloud gaming, as illustrated in Fig. 1,refers to the technologies that offload parts of game software from traditionalgame consoles or personal computers (PCs) to powerful and elastic cloudinfrastructures. Cloud gaming makes perfect sense to: 1) gamers, who otherwisehave to constantly upgrade their consoles or PCs, which is certainly no fun andcostly; 2) cloud service providers, who can sell the already-deployed andidling cloud resources to support the cutting-edge games that are extremelyresource hungry; and 3) game developers, who no longer need to spend months toport their games to different platforms. As such, cloud gaming has attractedsignificant attention from both academia and industry.
Initially, given the limited scales of these startups, people were notsure whether cloud gaming could be commercially successful. A fundamentalquestion that came to people, inside and outside the gaming circle, was: Willthe three dominating console manufacturers, Microsoft, Nintendo, and Sony, bewilling to give up their margin of selling the game consoles? The answer wasinitially unclear, and many suspected that these console manufacturers would bemore than happy to kill cloud gaming in order to remain profitable.
The opposite actually happened: Sony acquired GaiKai in 2012 for $380million, announced the new service PlayStation Now (PS Now) in early 2014, andbrought PS Now to parts of the world in 2015. Using PS Now, Sony allows theircustomers to play hundreds of PlayStation 3 (PS3) games on the latestPlayStation 4 (PS4) consoles without porting the games. Sony has also unveileda plan to: 1) allow gamers to use other PlayStation consoles and smart TV toaccess PS Now; and 2) include game titles developed for other generations ofPlayStations on PS Now. The emerging PS Now service indicates that cloud gaminghas great potential to become the next-generation, universal computer gamingplatform.
