The TVA metadata allows consumers to find, navigate, and manage contents through a variety of terminal devices including PDR, DTV, and IPTV. In general, a TVA metadata description is delivered from a content provider to a terminal device over a transport link. Because such metadata description can become very large, it is essential to encode each fragment of the metadata description in a compressed format before the delivery and then decode the encoded fragments at the terminal device. This paper proposes a new encoding procedure for TVA metadata based on the EXI and presents performance comparison results between the proposed encoding procedure and the existing TVA encoding procedure.
