    摘要: In an authentication system, a key registration apparatus receives input of an identifier unique to a second device, generates first key data from the identifier according to a predetermined key generation algorithm, and transmits the generated first key data to a first device, which receives and stores the first key data, and authenticates the second device with use of the first key data. The second device stores in advance second key data generated from the identifier according to the predetermined key generation algorithm, and is authenticated by the first device with use of the second key data. Accordingly, the first and second devices cannot be registered without using the key registration apparatus, thereby preventing communication with unregistered devices. This enables usage of content to be limited to individual usage in the home of a user, and can be realized even with devices that are not connected outside the home.

    摘要: A game system is composed of a home game execution apparatus and a portable game execution apparatus. The home game execution apparatus generates image data suitable for the image quality of the home game execution apparatus and image data suitable for the image quality of the portable game apparatus, transmits the pieces of the image data as necessary, and writes a game program to a portable recording medium. The portable game execution apparatus executes the game recorded on the portable recording medium while displaying the portable image received over the network. As a result, each game execution apparatus is able to execute the same game while displaying image data of an image quality suitable for the particular game execution apparatus.

    摘要: A game system in which game software produced to be used in stationary game machines can be used in portable game machines. The game system includes a stationary game machine, a portable game machine, and a memory card connectable to both the stationary and portable game machines. Image data contained in game software produced for the stationary game machine shows an image in the form of free-form surface. The stationary game machine converts the image data to show the image in the form of a polygon according to processing performance of the portable game machine, and stores the converted image data and a game program executable by the portable game machine onto the memory card. The portable game machine executes the game program stored on the memory card, and generates and displays a display image from the image data stored on the memory card.
