Abstract:
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.
Abstract:
Provided are a transmission system, a receiving terminal, and a method for controlling XML-based data broadcasting contents through data channels in a T-DMB. In the transmission system, a data broadcasting transfer server transfers the data broadcasting contents, and a control command transfer server generates control command data according to a control action of a service provider with respect to the data broadcasting contents. A multiplexer multiplexes the data broadcasting contents and the control command data and transmits the multiplexed data broadcasting contents and control command data through data channels.
