METHOD FOR TRANSFORMING TERRESTRIAL DMB CONTENTS AND GATEWAY EMPLOYING THE SAME

摘要

The present invention provides a gateway for transforming a terrestrial digital multimedia broadcasting (DMB) contents. A gateway for transforming a terrestrial DMB contents includes an ensemble transport interface (ETI) demultiplexing unit for dividing the terrestrial DMB contents having ETI frame format into a fast information channel (FIC) and a main service channel (MSC); a session description protocol (SDP) packet processing unit for converting the FIC into a SDP packet; a transmission control protocol/Internet protocol (TCP/IP) packet generating unit for generating a TCP/IP packet based on the SDP packet; a real-time transport protocol (RTP) packet processing unit for converting the MSC into a first RTP packet; a user datagram protocol/Internet protocol (UDP/IP) packet generating unit for generating a UDP/IP packet based on the RTP packet; and an IP output unit for transmitting the TCP/IP packet and the UDP/IP packet through an IP network.
