Patent ID: 7895248

Claim:
A disc drive apparatus comprising: a receiving device that receives clip data, via a network, generated by one of an information editing apparatus which edits clip data and an image pick up apparatus which obtains clip data, wherein the clip data includes at least real time metadata attached thereto; a UMID (unique material identifier) generating device, that determines if UMID is attached to the received clip data and that generates UMID corresponding to the received clip data when UMID is not attached to the received clip data; a nonreal time metadata generating device that (a) determines if nonreal time metadata is attached to the received clip data, (b) when nonreal time metadata is attached, confirms whether UMID included in the attached nonreal time metadata is associated with stored clip data and (c) generates nonreal time metadata which corresponds to the received clip data when nonreal time metadata is not attached to the received clip data; a transmitting device that transmits the nonreal time metadata to the information editing apparatus; and a disc recording device that stores (a) the received clip data, and (b) the generated UMID and generated nonreal time metadata associated with the received clip data and that overwrites the nonreal time metadata when UMID is confirmed by the nonreal time metadata generating device.
