1. A method for content conversion verification for a secondary use of already-distributed audiovisual content data, comprising:
converting, at a first computer system, the already-distributed audiovisual content data to a target format to generate a converted content file in the target format,
wherein the already-distributed audio visual content data includes video and audio data, and
wherein said converting to the target format enables reuse of same quality of the video and audio data in the already-distributed audio visual content data;
generating a checksum for the converted content file; and
sending the already-distributed audiovisual content data and the checksum to a second computer system,
wherein the checksum is generated and sent to the second computer system when the secondary use of the already-distributed audiovisual content data is requested by the second computer system,
wherein the already-distributed audiovisual content data is converted to the target format and a local checksum is generated for a file in the target format in the second computer system simultaneously.
