BROADCAST CONTENTS TRANSMISSION DEVICE, BROADCAST CONTENTS RECEIVING DEVICE, BROADCAST CONTENTS TRANSMISSION METHOD, BROADCAST CONTENTS RECEIVING METHOD, AND PROGRAM

摘要

A contents input unit (201) receives an IP packet (or an Ethernet frame) having broadcast contents. A sharing unit (202) shares, on the basis of a predetermined system, the Ethernet frame received into hierarchies of different digital broadcasts of A-hierarchy and B-hierarchy. The Ethernet frame shared into the A-hierarchy is subjected to a capsulation treatment at an A-Hierarchy treatment unit (203), and is sent together with capsulation system information to a ground digital broadcast network. On the other hand, the Ethernet frame shared into the B-Hierarchy is also subjected to the capsulation treatment at a B-Hierarchy treatment unit (204), and is sent together with the capsulation system information to the ground digital broadcast network.
