[Task Management Number: 2005-S-403-02, Title: Intelligent Integrated Information Broadcasting (SmaR TV) Technology Development].

Since conventional digital broadcasting provides a broadcasting service according to a broadcasting standard, there is a limitation of backward compatibility in providing a new service. Here, the backward compatibility constraint is that even if a new broadcast service is provided, a user who was receiving the existing broadcast service should be able to continuously receive the existing broadcast service.

Due to the backward compatibility problem of maintaining the existing broadcasting standards, it is difficult to provide new multimedia services such as 3D video services using new technologies such as new compression schemes and new transmission schemes.

Here, the basic service transmitters 10a, 11a, and 12a that provide basic services are the same as the existing digital broadcasting system structure, and the integrated additional service transmitters (transmitters) that provide various additional services 10b and 11b. , 12b and 13) add various additional data in the existing digital broadcasting scheme and integrate the added additional data and transmit it through one physical channel. Therefore, the present invention consists of N additional encoders 105, 115, 125, additional multiplexers 106, 116, 126, and integrated modulator 13 in existing digital broadcasting transmission systems (DMB, DTV).

In the following description of FIG. 1, since the existing digital broadcasting part is mentioned in the standard (DMB, DVB-T, ATSC), the description will be briefly described, and an additional part (integrated additional service transmitter) will be described. do.

First, the basic service transmitters 10a, 11a, and 12a will be described.

The basic service transmitters 10a, 11a, and 12a include an encoder, a multiplexer, a PSI / PSIP generator, and a modulator, which are provided as many as the number of basic services. Each base service transmitter (10a, 11a, 12a) is an encoder (101, 111, 121), PSI / PSIP generator (102, 112, 122), encoding a corresponding base source (basic service source), the corresponding PSI A multiplexer (103, 113, 123) for generating a transport stream (information transport stream) containing information, and a modulator (104, 114, 124) for generating an RF signal for the basic transport stream.

Next, the integrated additional service transmitter (transmitter) 10b, 11b, 12b, 13 will be described.

The integrated supplementary service transmitter (transmitter) includes a plurality of supplementary service transport stream (TS) generators 10b, 11b, and 12b and the supplementary service integrated modulator 13, where the supplementary service transport stream (TS) is generated. The units 10b, 11b, and 12b generate an additional transport stream (TS) including corresponding program service information (PSI) for each additional service source that is a broadcast service target, and include additional encoders 105, 115, and 125. Multiplexers 106, 116, 126.

When the additional service is a three-dimensional (3D) video service, binocular right image or depth information is used. The depth data of the scheme is an additional source. In addition, to increase the resolution of existing digital broadcasting through an additional service, for example, when extending the DMB system of QVGA (Quarter Video Graphics Array) resolution to SD (Standard Definition) or HD (High Definition), An encoder for a high resolution of an encoding method applying scalability may be used as an additional encoder.

Since the structure of FIG. 1 maintains backward compatibility with the existing basic service, the additional encoder may apply an encoding technique capable of applying a high-efficiency compression ratio without being limited by the existing standard. The additional encoders 105, 115 and 125 compress the source data to generate an elementary stream (ES). The generated elementary streams are multiplexed with the corresponding PSI information through an additional multiplexer to generate a transport stream (TS). do.

The additional multiplexers 106, 116, and 126 convert the elementary stream ES, which is a compressed stream output from the additional encoders 105, 115, and 125, into a transport stream TS. That is, the additional multiplexers 106, 116, and 126 generate a TS stream including PSI (Program and System Information) information, which is basic information generated by the PSI / PSIP generators 102, 112, and 122.

In order to improve the transmission efficiency of the integrated SI generation and the output of the integrated SI and PID filters 331a to 331e output from the control unit 32 are channel-coded.

The symbol mapper 333a to 333f symbolizes each output data output from the channel encoders 332a to 332f in a constant modulation scheme (QAM, etc.), and the FFT module 334 outputs the symbol mapper 333a to 333f. A subcarrier band is allocated to each symbol data for each additional service to generate one transmission signal (baseband transmission signal).

The DA / D converter 335 converts a digital signal into an analog signal, and the Up Converter 336 performs a frequency up-conversion of an intermediate frequency (IF) signal into an RF signal. (HPA) 337 power-amplifies the RF signal and transmits it through the antenna. Here, the DA converter 335, the up converter 336, and the high power amplifier (HPA) 337 may be collectively referred to as a "radio wave transmitting unit".
