Abrégé
(EN)
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.

本发明提供了用于变换地面数字多媒体广播(DMB)内容的网关。用于变换地面DMB内容的网关包括:信号群传输接口(ETI)解多路复用单元,用于将具有ETI帧格式的地面DMB内容划分为快速信息信道(FIC)和主服务信道(MSC);会话描述协议(SDP)分组处理单元,用于将FIC转换为SDP分组;传送控制协议/因特网协议(TCP/IP)分组生成单元,用于基于该SDP分组生成TCP/IP分组;实时传输协议(RTP)分组处理单元,用于将该MSC转换为第一RTP分组;用户数据报协议/因特网协议(UDP/IP)分组生成单元,用于基于该RTP分组生成UDP/IP分组;和IP输出单元,用于通过IP网络传送所述TCP/IP分组和UDP/IP分组。
