Sony has filed a patent application which describes several methods for using wireless connections in portable game machines. The methods described could very well be used with the PlayStation Portable (PSP) gaming device in the future.
The patent application, filed in June 2003, describes, for instance, ways of connecting a portable device to a "base computing device" which would do all the resource intensive calculations and feed the data to the portable device. The device would be responsible for mostly just playing back video and audio.
In addition to using the wireless connection to enable more complex games, the application suggest that content could be downloaded wirelessly to the device. The content would not be limited to just games, but would cover other digital content as well -- such as movies and music.
Sony has not commented on the application or it's connections to PSP. PlayStation Portable is expected to be launched in the Europe in March 2005.
