Overview: As MPEG-7 gets extended, DVB systems find the need to transport metadata over MPEG-2. This paper gives a view of a real implementation in an MHP application framework of the amendment ISO/IEC 13818-1:2000/Final Draft Amendment (FDAM) 1, which standardizes the carriage of MPEG-7 metadata over MPEG-2. The paper focuses mainly on the transport of metadata and how to synchronize metadata with the video content by means of Normal Play Time (NPT). The paper also presents some ways of broadcasting a Dynamic Metadata Service in a MHP application framework.
