NEC's video identification technology enables instant video content identification by extracting a unique descriptor called a "video signature" from video content. This technology is approved as the MPEG-7 Video Signature Tool; an international standard of interoperable descriptors used for video identification. The video signature is an extremely robust tool for identifying videos with alternations and editing effects. It facilitates search of very short video scenes. It also has a compact design, making ultrafast searches possible via a compact system. In this paper, we propose video identification solutions for the mass media industries. They adopt video signatures as metadata descriptions to enable efficient video registration operations and the visualization of video content relationships. Source

The purpose of the traditional image archiving system was to store the records of broadcasts. Since the standardization of the Material exchange Format (MXF), the management basis of image material has been shifting from tapes to files and the purpose of image archiving has been changing from storage to distribution. Nowadays, the archiving systems of NEC Corporation are capable not only of managing image material but also of constructing new business flow systems for the distribution of image material between broadcasters or between broadcasters and associated commercial interests.
