摘要：
A transmission system includes a transmission apparatus transmitting metadata relating to content via a network and a reception apparatus receiving the metadata. The transmission apparatus includes storing metadata including fragment updating management information in units of fragments; generating a delivery unit including a document which includes the metadata contained in fragments excluding the fragment updating management information; compressing the metadata in the delivery unit; adding document updating management information to the compressed metadata; and delivering the delivery unit. The reception apparatus includes receiving the compressed metadata; decompressing the compressed metadata; storing the decompressed metadata; and copy the document updating management information contained in the delivery unit and assign the document updating management information to the fragments as fragment updating management information.
