Digital Video Broadcasting (Terrestrial, DVB-T) transmission system can use Orthogonal Frequency Division Multiplexing (OFDM) modulation and link channel coding (such as coded orthogonal frequency division multiplexing (Coded) Orthogonal Frequency Division Multiplexing (COFDM)) is used to transmit Moving Picture Experts Group (MPEG) streams. 1 is a schematic functional block diagram of an embodiment of a terrestrial digital video broadcast transmission system including an animation expert group source code and multiplex unit 110, and a ground channel switch 120. The active expert group source code and multiplex unit 11 multiplexes images, sounds and data into MPEG Program Stream (MPEG PS) and one or more program streams. Can be combined to become a dynamic expert group to transmit streams. Animation Expert Group The program stream can be similar to MPEG-l, MPEG-2, MPEG_4, H.263 or H.264. Animation expert group transfer stream (MPEG 0758-A32141TWF; MTKI-06-054; LukeLee 7 200812385

Transport Stream, MPEG TS) is the basic digital stream transmitted and received by a digital television receiver. It is worth noting that two different transport streams can be transmitted simultaneously using a technique called "hierarchical transfer". For example, hierarchical transmission can transmit standard definition TV (SDTV) and high-definition television on the same carrier.

T number. Depending on the quality of the received signal, the digital TV receiver can choose to decode standard TV signals or high quality TV signals. A dynamic group transfer stream may not represent a fixed length data packet sequence (e.g., 188 bit length). The multiplex conversion and energy disperser 1211a or 121 lb can use energy dispersive techniques to reduce the correlation between bit sequences. External encoder 1213a or 1213b is used for the first level of data protection. For example, Reed Soloman (RS) (204, 188) is used to correct up to 8 error bits in each 188-bit packet. Conventional interleaving is the use of external interleaver 1215a or 1215b to rearrange the transmitted data sequence. The internal encoder 1217a or 1217b is used for the second level of transmission data protection. For example, a punctured convolutional code can be used based on an original revolving code having a coding rate of 1/2 and having 64 states. In addition, the internal encoder 1217a or 1217b may allow the original convolutional code with a coding rate of 1/2 to achieve a perforation rate of 2/3, 3/4, 5/6, and 7/8. The internal interleaver 1221 rearranges the data sequence again to reduce the effects of burst errors. A mapper 1223 maps the sequence of digits to a baseband modulation sequence of a complex symbol, for example using Quadratic Phase-Shift Keying (〇 - 758-A32141TWF; MTKI) -06-054;LukeLee 8 200812385 - QPSK) ' 16_ Quadrature Amplitude Modulation (16-QAM), 64-Quadrature Amplitude Modulation (64-QAM), non-single 16-quadrature amplitude modulation (non-uniform 16-QAM) or a non-uniform 64-QAM constellation. The picture converter 1227 aggregates the above complex symbols into a fixed length Τ block (e.g., each block has 1512, 3024 or 6048 complex symbols). One frame has 68 blocks' and one superframe has 4 faces. To simplify signal transmission to the terrestrial wireless channel, additional signals can be inserted into each block. The pilot signal 1225 can be used for the equalization phase, and the Transmission Parameters Signaling (TPS) 1225 can be used to transmit the parameters of the transmitted signal and uniquely identify the signal. The Orthogonal Frequency Division Multiplexer 1229 modulates these block sequences using 2048, 4096, or 8192 carriers (i.e., 2k, 4k, or 8k modes). In order to reduce the complexity of the receiver, each orthogonal frequency division multiplexing block can be extended by inserting the guard interval inserter 1231, for example, by copying the length of the tail portion at the beginning (i.e., the cyclic prefix). The length of the guard interval can be 1/32, 1/16, 1/8, or 1/4 of the length of the original block. The digital/analog converter 1233 converts the digital signal into an analog signal and is finally modulated by the RF front end 1235 at a radio frequency (VHF or UHF). The details of the terrestrial digital video broadcast transmission system can be based on the ES1TI standard: EN 300 744 V1.5.1, Digital Video Broadcasting (DVB); Framing structure 5 channel coding and modulation for digital terrestrial television (November 2004). 075 8-A32141 TWF;MTKI-06-054;LukeLee 9 200812385 ^ ^ # (Digital νί(ΐ6〇Broadcasting - 衔^W^纯) is the skill of the broadcast service used by the handheld receiver iiti ride number (four) like money One of the feed lines implements the J-work block diagram, including the handheld digital video broadcast decoder 210, Feng: Shih, and the terrestrial digital video broadcast code-tuning transformer 250.,.,,,,,,,,,,,, The physical layer Li and the lowest-level protocol components.

The baseband interface of the handheld digital video broadcasting system is the network protocol interface. This interface allows the handheld digital video broadcasting system to be combined with other network protocol-based networks. Multi-Protocol Encapsulation (MPE) is intended to be transmitted in a stream. τ t Additional Layer of Forward Error Correction (FEC) data, such as Multi-Protocol (Multi-Protocol) The Encapsulation-Forward Error Correction (MPE-FEC) layer can be attached to the multi-protocol encapsulation level. The multi-protocol encapsulation-forward error corrector 211 is located at the connection layer (iinkla). Yer), the multi-protocol encapsulation_forward error correction processing is performed before the multi-protocol encapsulator 213 does not perform the multi-protocol encapsulation of the network protocol input stream. The multi-protocol encapsulation-forward error corrector 211, the multi-protocol encapsulator 213 And the time division module 215 together constitutes a handheld digital video broadcast decoder 21, which includes the basic functions of the handheld digital video broadcasting system. The network protocol input stream, as an independent basic stream, is multiplexed according to the time division method. The multi-protocol encapsulation_forward error correction protection mechanism is calculated separately for each independent basic stream. The network protocol packet is then encapsulated and embedded in the transport stream. The multi-protocol encapsulation-forward error correction protection mechanism may include a Reed-Solomon code combined with a block interleaver. The Multi-Protocol Encapsulation-Forward Error Corrector 211 creates a specific facet architecture, forward error correction, and integrates the input data of the handheld digital shirt like the broadcast decoder 210. Figure 4 is a schematic diagram of an embodiment of a forward error correction plane comprising a maximum of 1024 columns and a fixed number of 255 rows. Each screen is 〇758-A32141TWF; MTKI-06-.〇54; LukeLee 11 200812385 yuan corresponds to one yuan, and the maximum surface capacity is about 2M bits. The forward error correction can be divided into two parts, the application data sheet is on the left side (line 191) and the Reed-Solomon data sheet is on the right side (line 64). The application profile populates the network contract packets for the service to be protected. After applying the Reed-Solomon (255,191) code to the application τ data for each column, the Reed-Solomon data Τ: the table contains the parity byte of the Reed-Solomon code. After encoding, the network protocol packet is read from the application data table and encapsulated into the network protocol segment in a multi-protocol encapsulation method. The application data for each line is followed by the co-located data from the Reed-Solomon data sheet and packaged into different forward error correction segments. Multiple protocol encapsulation - forward error correction is directly related to time division. Both techniques are applied to the basic stream hierarchy, and a time-segmented burst may include the content of one or more forward error correction planes. The details of the digital video broadcast transmission system can be based on the ESTI standard: EN 302 304 VI·1·1, Digital Video Broadcasting (DVB); Transmission System for Handheld Terminals (DVB-H) (November 2004).
