Claim 6:
7. A method for content conversion verification for a secondary use of the already-distributed audiovisual content data, comprising:
receiving, at a first computer system, the already-distributed audiovisual content data and a checksum from a second computer system,
wherein the checksum is generated and received from the second computer system when the secondary use of the already-distributed audiovisual content data is requested by the first computer system to the second computer system,
wherein the received checksum was generated at the second computer system after the already-distributed audiovisual content data was converted to a target format;
converting, at the first computer system, the received already-distributed audiovisual content data to the target format to generate a converted content file in the target format; and
generating, at the first computer system, a new checksum for the converted content file while the already-distributed audiovisual content data is being converted to the target format; and
wherein the received already-distributed audiovisual content data is segmented into a plurality of chunks so that (1) generating the new checksum and (2) comparing the received checksum and the new checksum are performed during the conversion of the already-distributed audiovisual content data to the target format.
