Archive-based content production was verified from different aspects. The archive featured an automatic tape-feed robot in combination with an HDD server and a DVD server. Content ID, a global unique code, was adopted for content and time code management. Both Content ID and time code were embedded in video content by digital watermarking. In such an environment the ID resolution test and the retrieval test by MPEG-7 description were executed. The effectiveness of content production was verified through these tests.
