2 South Korea T-DMB standard 2.1 T-DMB Network Architecture T-DMB network architecture shown in Figure 2.

Figure 2 Developed based on European manufacturers Eureka 147 digital audio Broadcasting (Eureka-147DAB) system based on T-DMB digital radio transmission, the structure shown in Figure 3.

Figure 3 T-DMB transmission frame by a synchronization channel (SC), fast information channel (F IC ), The main service channel (MSC) 3-channels form shown in Figure 4.

Figure 4 FIC block from the fast (FIB) structure, its main function is to explain the MSC sending the necessary control information configured, the control information is a core part of Multiplexer Configuration information ( MCI ), The multiplexer multiplexer structure contains configuration information and the required information with the information re-multiplexer. Included in the additional information within the FIC, said business information (SI), Conditional Access (CA) Management Information, and fast information data channel (FIDC). In order to allow fast and Security Response to MCI, FIC without time interleaving and the use of high-level protection to prevent the transmission error to send.

MSC by a series of public interlaced frames (CIF), each of CIF for a 55 296-bit data fields within each 24ms of transmission. CIF is the smallest addressable unit capacity units (CU), the size of 64 bits. CU group to form an integer number of basic transmission unit of MSC, here called subchannels. MSC thus constitute a sub-channel reuse.

MSC's operational definition of two different transmission modes: flow mode and packet mode. Flow pattern within the specified subchannel a fixed bit rate transmission; packet mode transmission within a single sub-channel number of data services, each of its sub-channel can transmit one or more business components.

T-DMB based on Eureka-147DAB, support for Korean, an increase of flow patterns through the data channel to transmit video, audio and data services capabilities, relevant content can refer to ETSIEN 300 401 standard.

T-DMB data channel through flow mode to transmit video, audio and data business to add a video multiplexer, the structure shown in Figure 5.

Figure 5 Figure 5, the relevant functional modules as follows:

Initial object descriptor (IOD) generator to ISO / IEC 14496-1 standard generated IOD.

Object descriptor (OD) / binary format scene description (BIFS) as a standard generator to ISO/IEC14496-1 generate OD / BIFS stream.

AVC video symbol Encoder Will enter the video signals, symbolic, and follow the standard H.264 / AVC.

BSAC audio codec will input audio signals, symbolic, and follow the ISO/IEC14496-3 bit slice arithmetic coding (BSAC) standards.

Synchronization layer (SL) packet from the input of various devices Multimedia Flow generated in the SL packet synchronization, and follow the ISO/IEC14496-1 system standards.

Section (Section) generator produces a IOD / OD / BIFS section, and follow the ISO/IEC13818-1 standards.

Packet elementary stream ( PES ) Packet-based device will enter the SL packets of PES packets, and follow the ISO/IEC13818-1 standards.

Transport stream (TS) multiplexer will enter the section and multiplexing PES packets into MPEG-2 TS.

Multiplexed MPEG-2 TS data flow through the external encoder RS (204,188) to add error protection information.

Through the external encoder RS (204,188) to add error protection of data flow in the convolution interleaver of interleaving a video Service Flow. (Continued)
