The application describes a number of scenarios for connecting a portable game player to a "base computing device," which could be a PC, a central server or an advanced game console such as the upcoming PlayStation 3.
Under one scenario, the central computer would be used as a "content execution server," processing chunks of software code too complex for the portable gadget to crunch.
"The content execution server will act as a base computing device that will execute program instructions of the game and then transmit, via the wireless transceiver,...processed active program instructions to the portable game device," according to the application. "By preprocessing the game instructions at the content execution server...the receiving devices will not be required to have robust processing circuitry, which is commonly required to execute typical game programs that involve sophisticated mathematical operations, lighting adjustments, and graphics...The receiving device can concentrate on providing video display and providing audio output to the user."
The application goes on to describe a number of methods for using a wireless connection to download content to a portable device to get around limited storage and processing capacity on a handheld gadget. In one scenario, games and other content would be stored on a central server and uploaded to the portable device when needed.
"In addition to games, it should be understood that the data being held by the content execution server may also include other digital data," according to the application. "Examples of other digital data may include, but (are) not limited to, movies, DVD data, music, or other entertainment or business digital content."
While the application most frequently cites PCs and living room game consoles as server connections, it also envisions Wi-Fi on the go.
"In today's wired world, many users are able to access hot spots free of charge in many locations such as coffeehouses, airports, gas stations, and the like," according to the application. "Once the user is close enough to the access point, the user can log in to the Internet server and use their previously purchased games or purchase new games for entertainment. In another embodiment, the remote access user can access their own video games that are stored on their home system, such as the content execution server or a game CD loaded into a game console."
