Although cloud game services transfer processing to remote servers and eliminate the need for powerful hardware, it also makes players more dependent on Internet connections. Google is giving the stadia cloud game service a new feature – support for AV1 decoder to minimize data traffic without sacrificing image quality. < p > < p > game streams are almost interactive video streams, and the graphics rendered and collected on remote servers will be sent to users’ mobile phones, computers or chromecast. As with any image or video, the higher the quality, the larger the file. The larger the file, the more bandwidth it takes up, which can increase users’ monthly Internet bills or reach the data limit faster. < / P > < p > at present, the best solution is to compress the data as tightly as possible, and then decompress it by the local device. In this process, the role of codecs is to balance the speed and efficiency. AV1 codec is the abbreviation of alliance for open media (aomedia) video 1, which was released in 2018. < / P > < p > the search giant is trying to use codecs for stadia, Google play movies, Google meet and even Google photos. Google has been touting the technology’s higher performance on low bandwidth connections, which can be used by game streams even on high bandwidth connections. < / P > < p > unfortunately, there are no more details about this goal, let alone a timetable for achieving it. There are still some open questions, such as whether AV1 is to be used throughout stadia or only under certain network conditions.
