  • the disk drive of the new-generation game device 300 reads the disk 302 (S 111 ) and acquires the reproduced signal supplied to the internal bus (S 112 ).
  • the new-generation game device 300 acquires the controller signal input from the game device controller 306 (S 114 ) and acquires the data input and output in the memory card 304 (S 116 ). Subsequently, the new-generation game device 300 superimposes the internal bus signal, various data including controller data and memory card data onto each other (S 118 ). The data for transmission thus superimposed is encrypted (S 120 ), converted into a USB signal, and transmitted to the compatibility adapter 200 via the USB connection cable 201 (S 122 ).
  • the compatibility adapter 200 receives the USB signal from the new-generation game device 300 and runs a compatibility process (S 140 ). The compatibility process by the compatibility adapter 200 will be described in detail in FIG. 8 .
  • the new-generation game device 300 receives the data subjected to the compatibility process in the form of a USB signal from the compatibility adapter 200 (S 124 ).
  • the new-generation game device 300 decodes the encrypted USB signal thus received (S 126 ), isolates and retrieves the respective signals, and places the signals on the bus (S 128 ). Thereby, the controller signal, the data to be output to the memory card, the audio signal, the video signal, etc. are retrieved.
  • the new-generation game device 300 outputs sound and video (S 130 ).
  • the new-generation game device 300 vibrates the game device controller 306 in accordance with the controller signal (S 132 ).
  • the new-generation game device 300 also writes the data to be output to the memory card into the memory card 304 (S 134 ).
  • FIG. 8 is a flowchart showing how the compatibility process in S 140 by the compatibility adapter 200 proceeds in detail.
  • the USB unit 211 of the compatibility adapter 200 receives the USB signal from the new-generation game device 300 (S 142 ), and the encryption unit 214 decodes the encrypted USB signal (S 144 ).
  • the CPU/DMA/MAC 216 isolates the decoded signals and feeds the signals to respective buses (S 146 ). Thereby, the controller signal, the data to be output to the memory card, the audio signal, the video signal, etc. are retrieved.
  • the DVD decoder emulator 226 of the new-generation game device 300 receives the reproduced signal read from the disk 302 and demodulates the signal (S 148 ).
  • the I/O processor 234 receives the signals from the CPU/DMA/MAC 216 and delivers the signals to the main processor 232 (S 150 ).
  • the main processor 232 performs computation based on the received data and outputs the result to the graphics processor 238 and the sound processor 236 (S 152 ).
  • the graphics processor 238 delivers video data to the CPU/DMA/MAC 216
  • the sound processor 236 delivers sound data to the CPU/DMA/MAC 216
  • the CPU/DMA/MAC 216 superimposes the video signal and the audio signal onto each other (S 154 ).
  • the encryption unit 214 encrypts the superimposed data for transmission and delivers the encrypted data to the USB unit 211 (S 156 ).
  • the USB unit 211 transmits the USB signal to the new-generation game device 300 (S 158 ).
  • the transmitted data includes controller data for vibrating the game device controller 306 and memory card data to be written in the memory card 304 .
  • the present invention can be used as a compatibility adapter device externally connected to an entertainment device.
