Multiplexed secure video game play distribution
摘要:
Multiple video game players access an encrypted video game library stored on a shared mass storage device. A multiplexer multiplexes data read from the mass storage device to provide output streams to multiple video game playing units consuming video game instructions. A secure bus communicates video game instructions from the shared mass storage device to each of the video game playing units. Video game software or other entertainment content is distributed to the shared mass storage device via electronic download in multi-level encrypted form. Before being transported, the content is encrypted and then further encrypted. Once the content has been successfully transported, it is decrypted to remove the further encryption layer—leaving the first encryption layer intact for protecting the video game during storage on mass storage at the remote distribution location.
