Abstract: Disclosed is a toy system for downloading digital contents via the internet and processing the downloaded digital contents through real time cooperation between a computer and a toy. The computer comprises a recording medium which stores digital contents and a digital contents driving program. The toy comprises a microprocessor, a communication port, a digital sound decoder, a speaker, a motor driving unit, a motor, an LED/lighting device and an LED/lighting device control unit. The digital contents comprise image data, first and second sound data and motion control data. The digital contents driving program processes the following steps: reading the digital contents; displaying the image data of the digital contents on a screen of the computer; outputting the second sound data of the digital contents to a speaker of the computer; and transmitting the first sound data and the motion control data of the digital contents as a packet form to the toy connected with the computer.

Abstract: Apparatus and method for preventing reproduction/distribution of digital goods by use of physical goods uses an inherent ID given to the physical goods. A first encrypted ID and an assignable identification name are also given to the goods. A second encrypted ID is generated when the assignable identification name registered upon the purchases of digital goods coincides with an inputted identification name. The present invention transfers, upon the purchase of the digital goods, the second encrypted ID and the purchased digital goods or the second encrypted ID and encrypted digital goods generated by encrypting the purchased digital goods according to the first encryption algorithm, and extracts the first encrypted ID from the second encrypted ID upon executing the digital goods.
